Creating a configurable Webhook module for a NestJS application

In this article, I will describe the creation of two NestJS modules with different configuration methods: a utility module and a business module with its own database.

There is a lot of text and code here, who is too lazy to read, they can just look at the changes in the project code: https://github.com/nestjs-mod/nestjs-mod-fullstack/compare/460257364bb4ce8e23fe761fbc9ca7462bc89b61..ec8de9d574a6dbcef3c3339e876ce156a3974aae

1. We come up with and paint a feature

Before implementing a certain functionality, you first need to write out everything that it should be able to do and describe entities with components that we know about this functionality.

Description

When developing a highly isolated NestJS module, we integrate with other modules either through the module configuration, or through a broker or queue.

In my practice, the main part of integrations is the publication of events for which we are already writing handlers in the integration layer of two functional modules.

And what if you need to provide access to these events to external sites, then you will have to write additional logic for registering such sites and access verification logic.

This webhook module provides access to application and module events and has CRUD operations for managing webhooks.

Module Characteristics

  1. The name is WebhookModule;
  2. Scalability - the module does not have the ability to scale, it can only work in a monolith;
  3. Is it possible to call forFeature - no, since events and handlers are thrown through the forRoot options;
  4. Does it have its own database - yes, the module comes with migrations and a Prisma scheme for generating a client to work with the database;
  5. Multitenancy - yes, since the site can work according to the B2B scheme and each new business is a new externalTenantId;
  6. Softdelet - no, the softdelet will be connected separately after the completion of the entire project and only where it is really needed, in the future a module will appear to enable and disable database auditing and it will be possible to look at the history of changes by record ids;
  7. Other owners of records in the table except externalTenantId - no, the record is common to the entire externalTenantId.

Tables

  1. WebhookUser - table with module users
    1. id:uuid - identifier;
    2. externalTenantId:uuid - company identifier;
    3. externalUserId:uuid is the user ID of the authorization server;
    4. UserRole:WebhookRole - user role;
    5. createdAt:Date - date of creation;
    6. updatedAt:Date is the date of the change.
  2. Webhook - table with webhooks
    1. id:uuid is the identifier;
    2. eventName:string(512) is the unique name of the event;
    3. endpoint:string(512) is the remote site to which the POST request will be sent;
    4. enabled:boolean - is the webhook active;
    5. headers?:JSON - headers that will be transmitted when sending to a remote site;
    6. requestTimeout?:number - do I need to wait for a response from a remote site and the maximum number of milliseconds to wait (by default 5 seconds);
    7. externalTenantId:uuid - company ID;
    8. createdBy:uuid - who created the record;
    9. UpdatedBy:uuid - who updated the record;
    10. createdAt:Date - date of creation;
    11. updatedAt:Date is the date of the change.
  3. WebhookLog - table with the history of webhook calls
    1. id:uuid - identifier;
    2. request:JSON - request to the remote site;
    3. ResponseStatus:string(20) - response status of the remote site;
    4. response?:JSON - response of the remote site;
    5. webhookStatus:WebhookStatus - status;
    6. webhookId:uuid - webhook ID;
    7. externalTenantId:uuid - company ID;
    8. createdAt:Date - date of creation;
    9. updatedAt:Date is the date of the change.

Dictionaries

  1. WebhookRole - dictionary of roles
    1. `Admin' - can read/create/change/delete any entities of any externalTenantId;
    2. `User' - can read/create/change/delete any entities of your externalTenantId only.
  2. WebhookStatus - dictionary of query statuses
    1. Pending - in the queue;
    2. Process - in processing;
    3. Success - successful call;
    4. Error - the call returned an error;
    5. Timeout - the call did not have time to work out.

Who can work with the module

  1. Admin - REST-a request that has the externalUserId=ID_USER property in the Request, which has the Admin role, has full access to all CRUD operations (WebhookController - at the url /api/webhook);
  2. User - REST-a request that has the externalUserId=ID_USER property in the Request, which has the User role, has full access to all CRUD operations, but only within its externalTenantId.

2. Creating all the necessary empty libraries

Since we will have additional common utilities for working with Prisma, we need to create a special library for this.

Commands

./node_modules/.bin/nx g @nestjs-mod/schematics:library prisma-tools --buildable --publishable --directory=libs/core/prisma-tools --simpleName=true --projectNameAndRootFormat=as-provided --strict=true
Enter fullscreen mode Exit fullscreen mode

Console output

CREATE libs/core/prisma-tools/src/lib/prisma-tools.module.ts
Enter fullscreen mode Exit fullscreen mode

In order not to copy similar code from test to test as part of the tests, we will create a library for test utilities.

Commands

./node_modules/.bin/nx g @nestjs-mod/schematics:library testing --buildable --publishable --directory=libs/testing --simpleName=true --projectNameAndRootFormat=as-provided --strict=true
Enter fullscreen mode Exit fullscreen mode

Console output

CREATE libs/testing/src/lib/testing.environments.ts
CREATE libs/testing/src/lib/testing.module.ts
Enter fullscreen mode Exit fullscreen mode

In addition to the test and Prisma utilities, we will also have common utilities, we will also create our own library for them.

Commands

./node_modules/.bin/nx g @nestjs-mod/schematics:library common --buildable --publishable --directory=libs/common --simpleName=true --projectNameAndRootFormat=as-provided --strict=true
Enter fullscreen mode Exit fullscreen mode

Console output
$ ./node_modules/.bin/nx g @nestjs-mod/schematics:library common --buildable --publishable --directory=libs/common --simpleName=true --projectNameAndRootFormat=as-provided --strict=true

CREATE libs/common/src/lib/common.constants.ts
CREATE libs/common/src/lib/common.environments.ts
CREATE libs/common/src/lib/common.module.ts

Now we are creating a business model.

3. Adding a NestJS-mod module for working with migrations and a module for generating a Prisma client

Since for the @nestjs-mod/prisma module to work, it is necessary to transfer the module with the generated client to our database, which does not yet exist, then we transfer the @nestjs-mod/prisma itself, since it has a stub.

Adding new modules to apps/server/src/main.ts.

import { WEBHOOK_FEATURE, WEBHOOK_FOLDER } from '@nestjs-mod-fullstack/webhook';

// ...

bootstrapNestApplication({
  modules: {
    // ...
    core: [
      // ...
      PrismaModule.forRoot({
        staticConfiguration: {
          schemaFile: join(rootFolder, WEBHOOK_FOLDER, 'src', 'prisma', PRISMA_SCHEMA_FILE),
          featureName: WEBHOOK_FEATURE,
          prismaModule: isInfrastructureMode() ? import(`@nestjs-mod/prisma`) : import(`@nestjs-mod/prisma`),
          addMigrationScripts: false,
          nxProjectJsonFile: join(rootFolder, WEBHOOK_FOLDER, PROJECT_JSON_FILE),
        },
      }),
    ],
    // ...
    infrastructure: [
      // ...
      DockerComposePostgreSQL.forFeatureAsync({
        featureModuleName: WEBHOOK_FEATURE,
        featureConfiguration: {
          nxProjectJsonFile: join(rootFolder, WEBHOOK_FOLDER, PROJECT_JSON_FILE),
        },
      }),
      Flyway.forRoot({
        staticConfiguration: {
          featureName: WEBHOOK_FEATURE,
          migrationsFolder: join(rootFolder, WEBHOOK_FOLDER, 'src', 'migrations'),
          configFile: join(rootFolder, FLYWAY_JS_CONFIG_FILE),
          nxProjectJsonFile: join(rootFolder, WEBHOOK_FOLDER, PROJECT_JSON_FILE),
        },
      }),
    ],
  },
});
Enter fullscreen mode Exit fullscreen mode

We are launching the generation of additional code for infrastructure and customer prism.

Now we have generated all the Prisma clients and need to update the import in the file apps/server/src/main.ts.

import { WEBHOOK_FEATURE, WEBHOOK_FOLDER } from '@nestjs-mod-fullstack/webhook';

// ...

bootstrapNestApplication({
  modules: {
    // ...
    core: [
      // ...
      PrismaModule.forRoot({
        staticConfiguration: {
          schemaFile: join(rootFolder, WEBHOOK_FOLDER, 'src', 'prisma', PRISMA_SCHEMA_FILE),
          featureName: WEBHOOK_FEATURE,
          prismaModule: isInfrastructureMode() ? import(`@nestjs-mod/prisma`) : import(`@nestjs-mod-fullstack/webhook`), // <-- update
          addMigrationScripts: false,
          nxProjectJsonFile: join(rootFolder, WEBHOOK_FOLDER, PROJECT_JSON_FILE),
        },
      }),
    ],
  },
});

4. Adding migrations with the necessary tables and dictionaries

I usually create migration files with my hands using this template: V%Y%m%d%H%M__New Migration.sql.

After starting the generation of additional infrastructure code, additional commands for working with migrations appear in the library, the same commands can be run from the scripts of the root package.json.

Commands

# create migrations folder
mkdir ./libs/feature/webhook/src/migrations
npm run flyway:create:webhook
Enter fullscreen mode Exit fullscreen mode

Console output
$ mkdir ./libs/feature/webhook/src/migrations
npm rumkdir ./libs/feature/webhook/src/migrations

$ npm run flyway:create:webhook

> @nestjs-mod-fullstack/source@0.0.8 flyway:create:webhook
> ./node_modules/.bin/nx run webhook:flyway-create-migration


> nx run webhook:flyway-create-migration

> echo 'select 1;' > ./libs/feature/webhook/src/migrations/V`date +%Y%m%d%H%M`__NewMigration.sql

7. Let's recreate the Prisma schema using the new database

We update the libs/feature/webhook/src/prisma/schema.prisma scheme previously created by the Prisma generator, and add an additional dto file generator.

generator client {
  provider = "prisma-client-js"
  engineType = "binary"
  output   = "../../../../../node_modules/@prisma/webhook-client"

}

datasource db {
  provider          = "postgres"
  url               = env("SERVER_WEBHOOK_DATABASE_URL")
}

generator prismaClassGenerator {
  provider                 = "prisma-class-generator"
  output                   = "../lib/generated/rest/dto"
  dryRun                   = "false"
  separateRelationFields   = "false"

  makeIndexFile            = "false"
  clientImportPath         = "@prisma/webhook-client"

10. Installing the libraries that will be needed for the module to work

Since the handlers will run the http method, you need to install axis and its NestJS module.

Commands

npm i --save @nestjs/axios axios
Enter fullscreen mode Exit fullscreen mode

Console output
$ npm i --save @nestjs/axios axios

11. Deleting unnecessary files from created libraries

The generator creates a typical configuration of the NestJS-mod module, but we don't always need all the created files, so we delete all unnecessary ones.

rm -rf libs/common/src/lib
rm -rf libs/testing/src/lib
rm -rf libs/core/prisma-tools/src/lib/prisma-tools.configuration.ts

12. Adding common types that can be reused in other modules

The type with parameters used in the CRUD query of many records.

Creating a file libs/common/src/lib/types/find-many-args.ts

import { ApiPropertyOptional } from '@nestjs/swagger';

export class FindManyArgs {
  @ApiPropertyOptional({ type: Number })
  curPage?: number;

  @ApiPropertyOptional({ type: Number })
  perPage?: number;

  @ApiPropertyOptional({ type: String })
  searchText?: string;
}
Enter fullscreen mode Exit fullscreen mode

The type with additional information returned as a result of the response of the request for many records is passed: the current page and the total number of records.

Creating a file libs/common/src/lib/types/find-many-response-meta.ts

import { ApiProperty, ApiPropertyOptional } from '@nestjs/swagger';

export class FindManyResponseMeta {
  @ApiPropertyOptional({ type: Number })
  curPage?: number;

  @ApiPropertyOptional({ type: Number })
  perPage?: number;

  @ApiProperty({ type: Number })
  totalResults!: number;
}
Enter fullscreen mode Exit fullscreen mode

A type for returning the result as a single string when calling various procedures that do not return data.

Creating a file libs/common/src/lib/types/status-response.ts

import { ApiProperty } from '@nestjs/swagger';

export class StatusResponse {
  @ApiProperty({ type: String })
  message!: string;
}

13. Adding the "PrismaToolsModule" module with additional utilities for working with Prisma-orm

There are very few utilities at this stage, but as the application expands, there will be more.

Module environment variables

Information on how to transfer them can be found in the infrastructure document https://github.com/nestjs-mod/nestjs-mod-fullstack/blob/master/apps/server/INFRASTRUCTURE.MD, using the hidden: true option we hide when generating .env files.

Example of environment variables:

Key Description Sources Constraints Default Value
useFilters Use filters. obj['useFilters'], process.env['SERVER_USE_FILTERS'] optional true true
paginationInitialPage Pagination initial page. obj['paginationInitialPage'], process.env['SERVER_PAGINATION_INITIAL_PAGE'] optional 1 1
paginationPerPageSteps Pagination per page steps. obj['paginationPerPageSteps'], process.env['SERVER_PAGINATION_PER_PAGE_STEPS'] optional - -
paginationPerPage Pagination per page. obj['paginationPerPage'], process.env['SERVER_PAGINATION_PER_PAGE'] optional 5 5

Updating the file libs/core/prisma-tools/src/lib/prisma-tools.environments.ts

import { ArrayOfStringTransformer, BooleanTransformer, EnvModel, EnvModelProperty, NumberTransformer } from '@nestjs-mod/common';

@EnvModel()
export class PrismaToolsEnvironments {
  @EnvModelProperty({
    description: 'Use filters.',
    transform: new BooleanTransformer(),
    default: true,
    hidden: true,
  })
  useFilters?: boolean;

  @EnvModelProperty({
    description: 'Pagination initial page.',
    transform: new NumberTransformer(),
    default: 1,
    hidden: true,
  })
  paginationInitialPage?: number;

  @EnvModelProperty({
    description: 'Pagination per page steps.',
    transform: new ArrayOfStringTransformer(),
    default: [1, 2, 5, 10, 25, 100],
    hidden: true,
  })
  paginationPerPageSteps?: (number | string)[];

  @EnvModelProperty({
    description: 'Pagination per page.',
    transform: new NumberTransformer(),
    default: 5,
    hidden: true,
  })
  paginationPerPage?: number;
}

Class with module errors

Although at this stage the backend is available as a REST service, errors are not inherited from Http errors, instead there is a special filter that maps errors.

This class, dictionaries and error descriptions probably shouldn't have been in this module, well, I still haven't figured out where to move them, so in all my projects it all lies also in the PrismaToolsModule module.

Creating a file libs/core/prisma-tools/src/lib/prisma-tools.errors.ts

export enum DatabaseErrorEnum {
  COMMON = 'DB-000',
  UNHANDLED_ERROR = 'DB-001',
  UNIQUE_ERROR = 'DB-002',
  INVALID_IDENTIFIER = 'DB-003',
  INVALID_LINKED_TABLE_IDENTIFIER = 'DB-004',
  DATABASE_QUERY_ERROR = 'DB-005',
  NOT_FOUND_ERROR = 'DB-006',
}

export const DATABASE_ERROR_ENUM_TITLES: Record<DatabaseErrorEnum, string> = {
  [DatabaseErrorEnum.COMMON]: 'Common db error',
  [DatabaseErrorEnum.UNHANDLED_ERROR]: 'Unhandled error',
  [DatabaseErrorEnum.UNIQUE_ERROR]: 'Unique error',
  [DatabaseErrorEnum.INVALID_IDENTIFIER]: 'Invalid identifier',
  [DatabaseErrorEnum.INVALID_LINKED_TABLE_IDENTIFIER]: 'Invalid linked table identifier',
  [DatabaseErrorEnum.DATABASE_QUERY_ERROR]: 'Database query error',
  [DatabaseErrorEnum.NOT_FOUND_ERROR]: 'Not found error',
};

export class DatabaseError<T = unknown> extends Error {
  code = DatabaseErrorEnum.COMMON;
  metadata?: T;

  constructor(message?: string | DatabaseErrorEnum, code?: DatabaseErrorEnum, metadata?: T) {
    const messageAsCode = Boolean(message && Object.values(DatabaseErrorEnum).includes(message as DatabaseErrorEnum));
    const preparedCode = messageAsCode ? (message as DatabaseErrorEnum) : code;
    const preparedMessage = preparedCode ? DATABASE_ERROR_ENUM_TITLES[preparedCode] : message;

    code = preparedCode || DatabaseErrorEnum.COMMON;
    message = preparedMessage || DATABASE_ERROR_ENUM_TITLES[code];

    super(message);

    this.code = code;
    this.message = message;
    this.metadata = metadata;
  }
}

Module Services

The modules have a service with various utilities, at the moment it has only two functions: converting part of the Prisma-orm errors into the format we need and a function for obtaining record offset based on frontend pagination.

Creating a file libs/core/prisma-tools/src/lib/prisma-tools.service.ts

import { FindManyArgs } from '@nestjs-mod-fullstack/common';
import { ConfigModel } from '@nestjs-mod/common';
import { Logger } from '@nestjs/common';
import { basename } from 'path';
import { PrismaToolsEnvironments } from './prisma-tools.environments';
import { DATABASE_ERROR_ENUM_TITLES, DatabaseErrorEnum } from './prisma-tools.errors';

@ConfigModel()
export class PrismaToolsService {
  private logger = new Logger(PrismaToolsService.name);

  constructor(private readonly prismaToolsEnvironments: PrismaToolsEnvironments) {}

  // eslint-disable-next-line @typescript-eslint/no-explicit-any
  convertPrismaErrorToDbError(exception: any) {
    try {
      const stacktrace = String(exception?.stack)
        .split(`${__dirname}/webpack:/${basename(__dirname)}/`)

            return {
              message: DATABASE_ERROR_ENUM_TITLES[DatabaseErrorEnum.INVALID_IDENTIFIER],
              stacktrace,
              code: DatabaseErrorEnum.INVALID_IDENTIFIER,
              metadata: exception?.meta,
              originalError,
            };
          }
          const relatedTable = exception.meta?.['cause'].split(`'`)[1];
          this.logger.debug({

          return {

            metadata: exception?.meta,
            originalError,
          };
        }

        this.logger.debug({ ...exception });

        return {
          message: DATABASE_ERROR_ENUM_TITLES[DatabaseErrorEnum.DATABASE_QUERY_ERROR],
          stacktrace,
          code: DatabaseErrorEnum.DATABASE_QUERY_ERROR,

  getFirstSkipFromCurPerPage(

Filter for module errors

As part of the backend application, each module has its own error types, but when sending an error to the frontend, we must convert it into an Http error, for such a conversion we create a PrismaToolsExceptionsFilter.

Creating a file libs/core/prisma-tools/src/lib/prisma-tools.filter.ts

import { ArgumentsHost, Catch, HttpException, HttpStatus, Logger } from '@nestjs/common';
import { BaseExceptionFilter } from '@nestjs/core';
import { PrismaToolsService } from './prisma-tools.service';
import { PrismaToolsEnvironments } from './prisma-tools.environments';

@Catch()
export class PrismaToolsExceptionsFilter extends BaseExceptionFilter {
  private logger = new Logger(PrismaToolsExceptionsFilter.name);

  constructor(private readonly prismaToolsService: PrismaToolsService, private readonly prismaToolsEnvironments: PrismaToolsEnvironments) {
    super();
  }

  override catch(exception: HttpException, host: ArgumentsHost) {
    if (!this.prismaToolsEnvironments.useFilters) {
      super.catch(exception, host);
      return;
    }
    const parsedException = this.prismaToolsService.convertPrismaErrorToDbError(exception);
    if (parsedException) {
      super.catch(new HttpException(parsedException, HttpStatus.BAD_REQUEST), host);
    } else {
      this.logger.error(exception, exception.stack);
      super.catch(exception, host);
    }
  }
}
Enter fullscreen mode Exit fullscreen mode

NestJS-mod module

This is a simple module that can take some parameters from environment variables and export the service with utilities to the outside.

Creating a file libs/core/prisma-tools/src/lib/prisma-tools.module.ts

import { createNestModule, NestModuleCategory } from '@nestjs-mod/common';
import { PRISMA_TOOLS_MODULE } from './prisma-tools.constants';
import { PrismaToolsEnvironments } from './prisma-tools.environments';
import { PrismaToolsService } from './prisma-tools.service';
import { APP_FILTER } from '@nestjs/core';
import { PrismaToolsExceptionsFilter } from './prisma-tools.filter';

export const { PrismaToolsModule } = createNestModule({
  moduleName: PRISMA_TOOLS_MODULE,
  environmentsModel: PrismaToolsEnvironments,
  moduleCategory: NestModuleCategory.core,
  providers: [{ provide: APP_FILTER, useClass: PrismaToolsExceptionsFilter }],
  sharedProviders: [PrismaToolsService],
});

14. Adding the "WebhookModule" module to work with webhooks

Module environment variables

The module has a built-in Guard and Filter, which can be disabled via environment variables if you want to customize the implementation and then manually bind them to modules or the entire application.

At startup, the module creates a user with the Admin role, whose value of the externalUserId field is taken from the environment variable.

User identification occurs by searching for the value of the variable externalUserId in the Request, which means that there must be some kind of guard standing earlier or global, in which the externalUserId is determined and set in the Request.

In addition to Request, there is also an unsafe way to transfer the ID of an external user, for this you can use Headers, at this stage of project development this method is enabled by default.

Example of environment variables:

Key Description Sources Constraints Default Value
useGuards Use guards. obj['useGuards'], process.env['SERVER_WEBHOOK_USE_GUARDS'] optional true true
useFilters Use filters. obj['useFilters'], process.env['SERVER_WEBHOOK_USE_FILTERS'] optional true true
autoCreateUser Auto create user from guard. obj['autoCreateUser'], process.env['SERVER_WEBHOOK_AUTO_CREATE_USER'] optional true true
checkHeaders Search tenantId and userId in headers. obj['checkHeaders'], process.env['SERVER_WEBHOOK_CHECK_HEADERS'] optional true true
skipGuardErrors Skip any guard errors. obj['skipGuardErrors'], process.env['SERVER_WEBHOOK_SKIP_GUARD_ERRORS'] optional false false
superAdminExternalUserId User ID with super admin role. obj['superAdminExternalUserId'], process.env['SERVER_WEBHOOK_SUPER_ADMIN_EXTERNAL_USER_ID'] optional - 248ec37f-628d-43f0-8de2-f58da037dd0f

Updating the file libs/feature/webhook/src/lib/webhook.environments.ts

import { BooleanTransformer, EnvModel, EnvModelProperty } from '@nestjs-mod/common';

@EnvModel()
export class WebhookEnvironments {
  @EnvModelProperty({
    description: 'Use guards.',
    transform: new BooleanTransformer(),
    default: true,
    hidden: true,
  })
  useGuards?: boolean;

  @EnvModelProperty({
    description: 'Use filters.',
    transform: new BooleanTransformer(),
    default: true,
    hidden: true,
  })
  useFilters?: boolean;

  @EnvModelProperty({
    description: 'Auto create user from guard.',
    transform: new BooleanTransformer(),
    default: true,
    hidden: true,
  })
  autoCreateUser?: boolean;

  @EnvModelProperty({
    description: 'Search tenantId and userId in headers.',
    transform: new BooleanTransformer(),
    default: true,
    hidden: true,
  })
  checkHeaders?: boolean;

  @EnvModelProperty({
    description: 'Skip any guard errors.',
    transform: new BooleanTransformer(),
    default: false,
    hidden: true,
  })
  skipGuardErrors?: boolean;

  @EnvModelProperty({
    description: 'User ID with super admin role.',
  })
  superAdminExternalUserId?: string;
}
Enter fullscreen mode Exit fullscreen mode

Module configuration

Environment variables can be changed from stand to stand, but there are also settings that are set when building the application, they are the same between all stands.

These settings include the types of events that can be sent as webhooks, as well as the names of the header keys to identify the current user or the current company.

Updating the file libs/feature/webhook/src/lib/webhook.configuration.ts

import { ConfigModel, ConfigModelProperty } from '@nestjs-mod/common';
import { WebhookEvent } from './types/webhook-event-object';

@ConfigModel()
export class WebhookConfiguration {
  @ConfigModelProperty({
    description: 'List of available events.',
  })
  events!: WebhookEvent[];

  @ConfigModelProperty({
    description: 'The name of the header key that stores the external user ID.',
    default: 'x-external-user-id',
  })
  externalUserIdHeaderName?: string;

  @ConfigModelProperty({
    description: 'The name of the header key that stores the external tenant ID.',
    default: 'x-external-tenant-id',
  })
  externalTenantIdHeaderName?: string;
}
Enter fullscreen mode Exit fullscreen mode

Class with module errors

Since at this stage the project is being developed as a REST backend, which is available on the frontend as an OpenAPI library, the class with errors is also published in the Swagger schema.

In order for the error description to be more detailed, it uses decorators that add meta information that will be output to the Swagger schema.

Creating a file libs/feature/webhook/src/lib/webhook.errors.ts

import { ApiProperty, ApiPropertyOptional } from '@nestjs/swagger';

export enum WebhookErrorEnum {
  COMMON = 'WEBHOOK-000',
  FORBIDDEN = 'WEBHOOK-001',
  EXTERNAL_USER_ID_NOT_SET = 'WEBHOOK-002',
  EXTERNAL_TENANT_ID_NOT_SET = 'WEBHOOK-003',
  USER_NOT_FOUND = 'WEBHOOK-004',
  EVENT_NOT_FOUND = 'WEBHOOK-005',
}

export const WEBHOOK_ERROR_ENUM_TITLES: Record<WebhookErrorEnum, string> = {
  [WebhookErrorEnum.COMMON]: 'Webhook error',
  [WebhookErrorEnum.EXTERNAL_TENANT_ID_NOT_SET]: 'Tenant ID not set',
  [WebhookErrorEnum.EXTERNAL_USER_ID_NOT_SET]: 'User ID not set',
  [WebhookErrorEnum.FORBIDDEN]: 'Forbidden',
  [WebhookErrorEnum.USER_NOT_FOUND]: 'User not found',
  [WebhookErrorEnum.EVENT_NOT_FOUND]: 'Event not found',
};

export class WebhookError<T = unknown> extends Error {
  @ApiProperty({
    type: String,
    description: Object.entries(WEBHOOK_ERROR_ENUM_TITLES)
      .map(([key, value]) => `${value} (${key})`)
      .join(', '),
    example: WEBHOOK_ERROR_ENUM_TITLES[WebhookErrorEnum.COMMON],
  })
  override message: string;

  @ApiProperty({
    enum: WebhookErrorEnum,
    enumName: 'WebhookErrorEnum',
    example: WebhookErrorEnum.COMMON,
  })
  code = WebhookErrorEnum.COMMON;

  @ApiPropertyOptional({ type: Object })
  metadata?: T;

  constructor(message?: string | WebhookErrorEnum, code?: WebhookErrorEnum, metadata?: T) {
    const messageAsCode = Boolean(message && Object.values(WebhookErrorEnum).includes(message as WebhookErrorEnum));
    const preparedCode = messageAsCode ? (message as WebhookErrorEnum) : code;
    const preparedMessage = preparedCode ? WEBHOOK_ERROR_ENUM_TITLES[preparedCode] : message;

    code = preparedCode || WebhookErrorEnum.COMMON;
    message = preparedMessage || WEBHOOK_ERROR_ENUM_TITLES[code];

    super(message);

    this.code = code;
    this.message = message;
    this.metadata = metadata;
  }
}
Enter fullscreen mode Exit fullscreen mode

Types used

All available types of events that will be sent via webhooks should be described when connecting the module via the WebhookModule.forRoot(), since this list will be displayed on the frontend when creating webhooks.

In the example property, you need to pass an example of an object that we will send via webhook.

Creating a file libs/feature/webhook/src/lib/types/webhook-event-object.ts

import { ApiProperty } from '@nestjs/swagger';

export class WebhookEvent {
  @ApiProperty({ type: String })
  eventName!: string;

  @ApiProperty({ type: String })
  description!: string;

  @ApiProperty({ type: Object })
  example!: object;
}
Enter fullscreen mode Exit fullscreen mode

Information about all sent events is recorded in the WebhookLog table, its generated DTO contains fields that we set ourselves in the backend, so we create a new DTO based on the generated one and remove these fields.

We also create a DTO to form a response to the CRUD operation of reading many records.

Creating a file libs/feature/webhook/src/lib/types/webhook-log-object.ts

import { FindManyResponseMeta } from '@nestjs-mod-fullstack/common';

Some of the fields for the Webhook entity are exposed and checked on the backend. therefore, we create new DTO for interaction with the front based on the DTO generated from the database.

The WebhookUser entity, which is editable by admins, also needs to be limited by available fields.

The module has its own Guard that checks for the presence of the user and company ID in the Request property or in the Headers and also adds the webhookUser property in which it stores the created user of the module.

The feature modules that I create always have a table with users, since they can be moved to a separate microservice and a separate database at any time.

import { WebhookUser } from '../generated/rest/dto/webhook_user';

export type WebhookRequest = {
  webhookUser?: Omit<WebhookUser, 'Webhook_Webhook_createdByToWebhookUser' | 'Webhook_Webhook_updatedByToWebhookUser'> | null;
  externalUserId: string;
  externalTenantId: string;
  headers: Record<string, string>;

Module Decorators

The SkipWebhookGuard decorator is needed to exclude the controller method or the entire controller from theGuard check.

The CheckWebhookRole decorator starts checking the user's role availability.

The decorators CurrentWebhookRequest and CurrentWebhookUser are used to get information from the Request.

import { getRequestFromExecutionContext } from '@nestjs-mod/common';
import { createParamDecorator, ExecutionContext } from '@nestjs/common';

export const CurrentWebhookRequest = createParamDecorator((_data: unknown, ctx: ExecutionContext) => {
  const req = getRequestFromExecutionContext(ctx) as WebhookRequest;

});

export const CurrentWebhookUser = createParamDecorator((_data: unknown, ctx: ExecutionContext) => {
  const req = getRequestFromExecutionContext(ctx) as WebhookRequest;
  return req.webhookUser;
});

Module controllers

The main controller of the entire module is the WebhookController, it has CRUD operations to work with the Webhook entity, as well as the profile method to get the current user of the module.

The controller also has a findManyLogs method that returns the history of sent events.

The controller is available to the Admin and User roles, users with the Admin role can see and modify the webhooks of all companies, users with the User role can only see their own webhooks.

Filter for module errors

To convert module errors to an Http error, create a WebhookExceptionsFilter.

Creating a file libs/feature/webhook/src/lib/webhook.filter.ts

import { ArgumentsHost, Catch, HttpException, HttpStatus, Logger } from '@nestjs/common';
import { BaseExceptionFilter } from '@nestjs/core';
import { WebhookError } from './webhook.errors';

@Catch()
export class WebhookExceptionsFilter extends BaseExceptionFilter {

  override catch(exception: WebhookError | HttpException, host: ArgumentsHost) {
    if (exception instanceof WebhookError) {
      super.catch(
        new HttpException(
          {
            code: exception.code,
            message: exception.message,

NestJS-mod module

Unlike PrismaToolsModule (example: SERVER_USE_FILTERS), the environment variables of the current module will have a prefix (example: SERVER_WEBHOOK_USE_FILTERS), this is done by overriding getFeatureDotEnvPropertyNameFormatter.

Turning off the Guard and Filter on the controllers occurs by wrapping them in special decorators when the module is connected.

Conclusion

The createNestModule utility from the @nestjs-mod/common package provides various module configuration options for NestJS-mod and NestJS applications, this allows us not to invent our own configuration options.

Since the WebhookModule module has its own database, it can be moved to a separate microservice or reused in various projects.

Plans

In the next post, I will write a frontend for the webhooks module in Angular...
