Express jwt 2 

git clone https://github.com/andiks2018/JvalleyExpress-jwtPostman.git express_jwt_2
Enter fullscreen mode Exit fullscreen mode

buat file .env

DATABASE_URL="file:./db.sqlite"
PORT=8000
SECRET_KEY="masukanSecretKeyKamuTerserahApaAja"
Enter fullscreen mode Exit fullscreen mode

npx prisma db push

selanjutnya kita akan buat relasi di scheme prisma, serta mengganti author dengan user_id

//schema.prisma

// This is your Prisma schema file,
// learn more about it in the docs: https://pris.ly/d/prisma-schema

generator client {
  provider = "prisma-client-js"
}

datasource db {
  provider = "sqlite"
  url      = env("DATABASE_URL")
}

model Users {
  id        Int      @id @default(autoincrement())
  email     String   @unique
  password  String
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt

  //relation
  notes Notes[]
}

model Notes {
  id        Int      @id @default(autoincrement())
  title     String
  content   String
  user_id   Int
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt

  //relation
  user Users @relation(fields: [user_id], references: [id])
}
Enter fullscreen mode Exit fullscreen mode

setelah merubah data di model schema prisma selanjutnya kita db push ulang

npx prisma db push
selanjutnya kita akan jalankan server dengan perintah

npm run dev

selanjutnya kita buat file test.rest sebelumnya kita sudah menginstal extension REST Client for Visual Studio Code.

//test.rest


###
POST http://localhost:8000/user/register
Content-Type: application/json

{
    "email":"andi@andi.com",
    "password": "cobapassword"
}
Enter fullscreen mode Exit fullscreen mode

Image send request 201 created

Image berhasil

sebelumnya kita sudah membuat register user selanjutnya kita akan membuat login user di user_controller.js

//user_controller.js

import { request, response } from "express"
import db from "../../prisma/connection"
import jwt from "jsonwebtoken"
import env from "dotenv"
env.config()

// create user
export const user_register = async (req = request, res = response) => {
    try {

        // membaca request body
        const data = await req.body

        // tulis data dari body ke database
        const result = await db.users.create({
            data: data
        })

        const { SECRET_KEY } = process.env

        // generated token
        const token = jwt.sign({
            id: result.id,
            email: result.email
        }, SECRET_KEY)

        // kembalikan response json
        res.status(201).json({
            success: true,
            message: "user berhasil di tambahkan ke database",
            token: token
        })

    } catch (error) {
        res.status(500).json({
            success: false,
            error: error.message
        })
    }
}

//login user
export const user_login = async (req = request, res = response) => {
    try {

        //kita ambil body
        const data = await req.body

        //check email
        const checkEmail = await db.users.findUnique({
            where: {
                email: data.email
            }
        })

        //jika email tidak ditemukan di database
        if (!checkEmail) {
            return res.status(404).json({
                success: false,
                message: "email tidak ditemukan"
            })
        }

        //jika password tidak sama
        if (data.password !== checkEmail.password) {
            return res.status(401).json({
                success: false,
                message: "password kurang tepat"
            })
        }

        //generate token
        const token = jwt.sign({
            id: checkEmail.id,
            email: checkEmail.email
        }, process.env.SECRET_KEY)

        //kembalikan reseponse json
        res.status(500).json({
            success: true,
            message: "user berhasil di tambahkan ke database",
            token: token
        })

    } catch (error) {
        res.status(500).json({
            success: false,
            error: error.message
        })
    }
}
Enter fullscreen mode Exit fullscreen mode

tambahkan user login

//user_routes.js

import express from "express"
import { user_login, user_register } from "../controllers/user_controllers"

const user_routes = express.Router()

// user register
user_routes.post("/user/register", user_register)
user_routes.post("/user/login", user_login)

export default user_routes
Enter fullscreen mode Exit fullscreen mode

selanjutnya kita ke test.rest untuk menambahkan user login

//test.rest


### USER REGISTER
POST http://localhost:8000/user/register
Content-Type: application/json

{
    "email":"andi@andi.com",
    "password": "cobapassword"
}

### USER LOGIN

POST http://localhost:8000/user/login
Content-Type: application/json

{
    "email":"andi@andi.com",
    "password": "cobapassword"
}
Enter fullscreen mode Exit fullscreen mode

Image note

kita tidak bisa register dengan email yang sama,

Image send login dan register

kalau kita cek password generate muncul user dan id

Image jwt.io

kita butuh generate req bdy

//user_mdw.js

import { request, response } from "express"
import jwt from "jsonwebtoken"
import env from "dotenv"
env.config()

const user_mdw = async (req = request, res = response, next) => {
    try {
        // coba check apakah ada authorization
        const authorization = await req.headers.authorization
        if (!authorization) {
            return res.status(401).json({
                success: false,
                message: "authorization tidak ditemukan !"
            })
        }
        const token = await authorization.split(" ")[1]
        // validasi token
        const verify = await jwt.verify(token, process.env.SECRET_KEY)
        if (!verify) {
            return res.status(401).json({
                success: false,
                message: "Token tidak terverifikasi!"
            })
        }

        /**
         * {
         *  "id" : 1,
         *  "email" : 'andi@andi.com'
         * }
         * 
         * lanjut boss..
         */

        //generate req body
        req.body.user_id = verify.id
        req.body.email = verify.email
        next()

    } catch (error) {
        res.status(401).json({
            success: false,
            error: error.message
        })
    }
}

export default user_mdw
Enter fullscreen mode Exit fullscreen mode

lanjut ke test rest, tapi sebelumnya kita harus rubah data menjadi objek dengan inputan nilai title content dan user_id

Image data

//note_controller.js

import { request, response } from "express"
import db from "../../prisma/connection"

// read notes
export const notes_read = async (req = request, res = response) => {
    try {
        const result = await db.notes.findMany()
        res.status(200).json({
            success: true,
            notes: result
        })
    } catch (error) {
        res.status(500).json({
            success: false,
            error: error.message
        })
    }
}

// create note
export const notes_create = async (req = request, res = response) => {
    try {
        const data = await req.body
        const createNote = await db.notes.create({
            data: {
                title : data.title,
                content : data.content,
                uer_id : data.user_id
            }
        })
        res.status(201).json({
            success: true,
            message: "Berhasil menambahkan note ke database",
            note: createNote
        })
    } catch (error) {
        res.status(500).json({
            success: false,
            error: error.message
        })
    }
}
Enter fullscreen mode Exit fullscreen mode

tadi ada beberapa error http yang salagh tulis, kemudian ketika send request create note katanya jwt must provider. solusinya tadi kita hapus file db.sqlite kemudian kita

npx prisma db push ulang

maka kemudian send request ulang , register, login, dan create note.

Image berhasil login

sampai disini selesai create note

selanjutnya kita akan baca datanya dimana note user itu hanya bisa membaca note yang dia buat. read note sebelumnya in bisa membaca semua note yang ada,

Image notes read

//notes_controllers.js

import { request, response } from "express"
import db from "../../prisma/connection"

// read notes
export const notes_read = async (req = request, res = response) => {
    try {
        const data = await req.body
        const result = await db.notes.findMany({
            where: {
                user_id : data.user_id
            }
        })
        res.status(200).json({
            success: true,
            notes: result
        })
    } catch (error) {
        res.status(500).json({
            success: false,
            error: error.message
        })
    }
}

// create note
export const notes_create = async (req = request, res = response) => {
    try {
        const data = await req.body
        console.info(data)
        const createNote = await db.notes.create({
            data: {
                title : data.title,
                content : data.content,
                user_id : data.user_id
            }
        })
        res.status(201).json({
            success: true,
            message: "Berhasil menambahkan note ke database",
            note: createNote
        })
    } catch (error) {
        res.status(500).json({
            success: false,
            error: error.message
        })
    }
}
Enter fullscreen mode Exit fullscreen mode

Image note read

//test.rest


### USER REGISTER
POST http://localhost:8000/user/register
Content-Type: application/json

{
    "email":"andi3@andi.com",
    "password": "cobapassword"
}

### USER LOGIN

POST http://localhost:8000/user/login
Content-Type: application/json

{
    "email":"andi3@andi.com",
    "password": "cobapassword"
}

### NOTE CREATE

POST http://localhost:8000/notes/create
Content-Type: application/json
Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6NCwiZW1haWwiOiJhbmRpM0BhbmRpLmNvbSIsImlhdCI6MTY3Mjk3OTU1M30.EE_pXrJpClcwz7fzO0jL37orfXsHXalyCP3BGtlIvok

{
    "title":"ini judul saya",
    "content": "ini content saya "
}

### NOTE READ
GET http://localhost:8000/notes/read
Content-Type: application/json
Enter fullscreen mode Exit fullscreen mode

kalau seperti ini maka akan bisa membaca semua note yang sudah dibuat oleh semua user,

register

Image register

login

Image login

Create note user 6

Image note

Read note

Image note

cuman yang kita baca disini adalah semua note, sekarang kita pisahkan dengan middleware, kita notes_routes.js

Image mdw
3

//notes_routes.js

import express from "express"
import { notes_create, notes_read } from "../controllers/notes_controllers"
import user_mdw from "../middleware/user_mdw"

const notes_routes = express.Router()

// create 
notes_routes.post("/notes/create", user_mdw, notes_create)

// read 
notes_routes.get("/notes/read", user_mdw, notes_read)

export default notes_routes
Enter fullscreen mode Exit fullscreen mode

lanjut kita ke test.rest lagi untuk membaca note, harusnya sekarang sudah tidak bisa lagi di akses, kecuali memasukkan token user loginnya.

error tidak bisa membaca note

Image author

sekarang kita sudah bisa akses note yang kita buat tadi. kita baru membuat satu note.

Image note author
