This is a NodeJs application written in Typescript and some enhancement. By applying some design patterns and design architecture, unit test and integration test mechanism against a real database, caching mechanism with Redis, documentation with open API, Docker, CI/CD stuffs, authentication using both JWT and HMAC signature that helps this application consideration as a NodeJS (Typescript) boilerplate.

The idea of creating this application is to handle real-life requirements using a strong Node JS (Typescript) application using some design patterns, architecture, and the proper testing mechanism that helps the application's stability and scalability.

Build a task management API.

• User is able to register through an endpoint
• User is able login through an endpoint after registering
• A user is able to submit a task through an endpoint.
• The backend will consume the task (use a random timer delay to simulate some work).
• Through another endpoint, the user can check the status of the task.
• Store tasks in a database (MySQL)
• A task is first created as a draft with a 24h lifetime, it needs to be confirmed to be added to the task queue.
• Use Redis to store draft tasks
• Create an authentication procedure between the client and the server using either an HMAC signature and a shared secret

Follow these steps below to make sure the application running in the correct way:

• Makes sure you have installed Mysql, Redis, NodeJs, PM2 on your local machine before stating the application
• Otherwise, you should use Docker Container to host the application.

• Run the command npm i to install all the application dependencies.
• Modify .env.example file to .env and config the corresponding information into .env file
• Run the command npm run lint to checking the coding convention is strict.
• Run the command npm run format to format the Typescript code styles.
• Run the command npm run migration:create to create a database migration file.
• Run the command npm run migration:run to run all the current database migration.
• Run the command npm run migration:revert to revert the current database migration.
• Run the command npm run . to starting development the application.
• Run the command npm run build to compiler the application from TS to JS.
• Run the command npm run start:debug to enable debug mode.
• Run the command npm run test to performs the all the test.
• Run the command npm run test:compose to performs the all the test with Docker.

Run the commands below to build the application production mode: First we need to change NODE_ENV=production in the .env file

• Run the command npm run start to run application on production mode.
• Run the command npm run start:prod to build application with PM2 cluster.
• Run the command npm run stop to stop current application running on PM2 cluster.
• Run the command npm run delete to delete current application running on PM2 cluster.
• After running npm run start:prod the application will migration database automatically in production environment.

Run the application in Docker Environment:

• Make sure your local machine has been installed the Docker container.
• Run the command docker-compose up to starting development the application.
• Run the command docker-compose down to stop development the application.
• Run the command docker-compose up --build to rebuild the application.
• Run the command docker-compose up -d to build the application in the background. Note*: There are some other docker command need to hand on by your self.

• Change open api OPEN_API_USERNAME and OPEN_API_PASSWORD to what ever characters in .env file
• Otherwise, the credentials will set as default as shown below:
  • Username: task
  • Password: management
• Landing on http://localhost:3005/api/docs to open the Open API docs for local environment.
• Landing on {url}/api/docs to open the Open API docs for development/production environments.
• Use the default credentials or username/password setting up in the .env file for sign in to open API.
