A simplified Jira clone built with Angular 9, ng-zorro and Akita

There have been a handful of cool Jira-cloned apps written in React/VueJS, which makes me wonder Why not Angular? And here you go.

This is not only a simplified Jira clone built with Angular 9, but also an example of a modern, real-world Angular codebase.

A simplified Jira clone built with Angular 9, ng-zorro and Akita

If you like my work, feel free to⭐ this repository. And we will be happy together :)
Thanks a bunch for stopping by and supporting me!

Who is it for 🤷‍♀️

I have been working with Angular for about four years. I built cool stuff at Zyllem but almost all of them are internal apps which is difficult to show.

This is a showcase application I've built in my spare time to experiment the new library that I wanted to try before: Akita, TailwindCSS, ng-zorro.

There are many Angular examples on the web but most of them are way too simple. I like to think that this codebase contains enough complexity to offer valuable insights to Angular developers of all skill levels while still being relatively easy to understand.


This piece of work is also part of our technical series angular-vietnam/100-days-of-angular which aims at enabling everyone, after 100 days of learning Angular with us, to self-build their application with the similar scale. Our desire is to advocate and grow the Angular developer community in Vietnam.

High level design

As requested by @eric_cart, I draw a simple high-level design for the application.

Application architecture

I have an AppModule that will import:

Jira clone built with Angular 9 and Akita - Application architecture

  • Angular needed modules such as BrowserModule and any module that need to run forRoot.
  • The application core modules such as AuthModule that need to available on the whole platform.
  • And I also configured the router to lazy load any modules only when I needed. Otherwise, everything will be loaded when I start the application. For instance, LoginModule when I open the URL at /login and ProjectModule when the URL is /project. Inside each modules, I could import whatever modules that are required. Such as I need the JiraControlModule for some custom UI components for the ProjectModule

Simple data interaction flow

As I am using Akita state management, I follow the Akita documentation for the data flow. I found it is simple to understand comparing with ngrx terms (reducer, selector, effect)

Jira clone built with Angular 9 and Akita - Simple data interaction flow

I set up a project state with initial data. The main heavy lifting part I think is the project service, it contains all the interacting with project store. Such as after fetching the project successfully, I update the store immediately inside the service itself. The last lego block was to expose the data through project query. Any components can start to inject project query and consume data from there.

Features and Roadmap

I set the tentative deadline for motivating myself to finish the work on time. Otherwise, It will take forever to complete :)

Phase 1 - Angular application and simple Nest API

June 13 - 27, 2020

  • Proven, scalable, and easy to understand project structure
  • Simple drag and drop kanban board
  • Add/update issue
  • Search/filtering issues
  • Add comments

Noted: All of your interactions with data such as leave a comment or change the issue detail will not be saved to the persistent database. Currently, the application will serve a fixed structure of data every time you open the app. It means if you reload the browser, all of your changes will be gone.

Phase 2 will bring you a proper API where you can log in and save your work.

While working with this application, I have the opportunity to revisit some of the interesting topics:

  • TailwindCSS configuration - that's awesome
  • Scrollable layout with Flexbox
  • Deploy Angular application to Netlify

Phase 2

September ~ October 2020

  • Refactor the mono repo to use Nx Workspace
  • GraphQL API and store data on the actual database
  • Authentication

Tutorial

When I look at the application, it is huge. When the task is huge, you usually don't know where and how to start working with them. I started to break the big task into a simple to-do list on notion. Once I know what needs to be done, what I need is to follow the plan. That's my approach.

I learned a lot of stuff. I know you might also have a curiosity about the process of building the same scale app as well. That's why I am writing a tutorial series on how I built Angular Jira clone from scratch. I hope you guys will learn something from that too :)

I will try to be as detailed as possible. Hopefully through the tutorial, you will get the idea and will start working on your own application soon. Please bear with me.

Its series will also be published in Vietnamese as part of our angular-vietnam/100-days-of-angular.

Time spending

It is a side project that I only spent time outside of the office hours to work on. One day, my team and I were fire fighting on PROD until 11 PM. After taking a shower, I continue with Angular Jira clone for another two hours...

According to waka time report, I have spent about 45 hours working on this project. Which is equivalent to watch the whole Stranger Things series twice.

I really enjoyed working on this project. The interactive kanban board took me sometimes, it is challenging but exciting at the same time.

What's currently missing?

There are missing features from the live demo which should exist in a real product. All of them will be finished on Phase 2:

Proper backend API

I built a very simple NestJS API to send a fixed data structure to the client. All of your interactivity with data will only be saved on the memory. If you refresh the page, it will be gone. Phase 2 will bring the application to live by saving the data into a database.

Proper authentication system 🔐

I am currently sending the same email and a random password to the server without any check to get the current user back. Phase 2 will also bring a proper authentication system.

Accessibility ♿

Not all components have properly defined aria attributes, visual focus indicators, etc.

Setting up development environment 🛠

  • git clone https://github.com/trungk18/jira-clone-angular.git
  • cd jira-clone-angular
  • npm run start:front for angular web application
  • The app should run on http://localhost:4200/

Unit/Integration tests 🧪

I skipped writing test for this project. I might do it for the proper backend GraphQL API.

Compatibility

It was being tested on IE 11, Chrome and Firefox. For Safari, there are some minor alignment issues.

Hey, I like the look very much!
Especially that this is the topic of one of my side projects as well 😂.
Except I've focused more on basic functionality and what can be achieved with the API. Beside some prototyping and learning on various topics.
For example css grid as a board display, parsing JQL expressions.
I used angular and ngPrime.

Sounds great. Did you have publish it anywhere? I would like to see it. For a project like Jira clone, we can actually try and test a lot of technology and see how all of them are working nicely at the end. Looking for more projects from you! 😊

Hey, thanks. It is on bitbucket, but far from complete or mature enough for a real publication :)

bitbucket.org/kisp/jira-light/

Exploring the jira API lead to some dead-ends. I found that boards are provided on the agile endpoint, only after I have implemented a board view through a JQL query execution.

Before you do anything involving "agile" - you need to be sure about some basics about the api.

  1. The cloud-api and the agile-api are two different endpoints working over the same data with some extra entities
  2. There are customFields defined on the ticket, which can be accessed via ids - ('Story points' is one of them) Some custom fields has a default name, 'Story points' is one of them. The id can be found by name. SP exists on scrum boards only obviously. Boards and epics can be accessed through the agile api with project key. end-so-on.

In overall I was a little-bit struggling to find the entry-point for having a good grasp to get my tickets displayed.

Seems like you did the extensive research on how the actual Jira work. I only focus on the front end of thing 😁But anyway I am preparing an API with GraphQL with some basic functionality. If you would like to take a look, this is a branch name: github.com/trungk18/jira-clone-ang...

Basically it is the flow:

  1. User login, you get some basic user information.
  2. There should be an list of projects associate with an user, so probably you will need to fetch the list of project. Then open the last opened project (My API is not working exactly like that)
  3. Fetch the project detail and show the board. A project will have a list of
  4. Lanes: mapped to the status: Backlog, Selected, Inprogress, Done
  5. Each lane will have a list of issues
  6. Have several API to update issue.

I hope that I can deployed the 2.0 version with API very soon. I didn't think about the custom fields that you are mentioning but I am aware of that on the actual use of Jira.

Anyway, good luck with that jira-light!
