This project is designed for a production ready environment. It can handle the scale and complexity of a very demanding application. This project is being used by companies like MindOrks, AfterAcademy, and CuriousJr. Apps/Websites having 10+ million usebase.
It is suitable for Web Apps, Mobile Apps, and other API services.

We will learn and build the backend application for a blogging platform. The main focus will be to create a maintainable and highly testable architecture.
Following are the features of this project:
- This backend is written in Typescript: The type safety at build time and having intellisense for it in the IDE like vscode is unparalleled to productivity. I have found production bug reduced to a significant amount since most of the code vulnerabilities are identified during the build phase itself.
- Separation of concern principle: Each component has been given a particular role. The role of the components is mutually exclusive. This makes the project easy to be unit tested.
- Feature encapsulation: The files or components that are related to a particular feature have been grouped unless those components are required in multiple features. This enhances the ability to share code across projects.
- Centralised Error handling: I have created a framework where all the errors are handled centrally. This reduces the ambiguity in the development when the project grows larger.
- Centralised Response handling: Similar to Error handling we have a response handling framework. This makes it very convenient to apply a common API response pattern.
- Mongodb is used through Mongoose: Mongodb fits very well to the node.js application. Being NoSQL, fast, and scalable makes it ideal for modern web applications.
- Redis Memcache: I have used the redis server for caching the items which does not change frequently. It will boost the performance of our system.
- Async execution: I have used async/await for the promises and made sure to use the non-blocking version of all the functions with few exceptions.
- Docker compose has been configured: I have created the Dockerfile to provide the easy deployability without any setup and configurations.
- Unit test is favored: The tests have been written to test the functions and routes without the need of the database server. Integration tests has also been done but the unit test is favored.
- A pure backend project: I have experienced that when a backend is developed clubbed with a frontend then in the future it becomes really difficult to scale. We would want to create a separate backend project that servers many websites and mobile apps.

# clone repository recursively
git clone https://github.com/fifocode/nodejs-backend-architecture-typescript.git- Install Docker and Docker Compose. Find Instructions Here.
# install and start docker containers
docker-compose up --build- You will be able to access the api from http://localhost:3000
docker exec -t blogs-tester npm run testIf having any issue
- Make sure 3000 port is not occupied else change PORT in .env file.
- Make sure 27017 port is not occupied else change DB_PORT in .env file.
- Make sure 6379 port is not occupied else change REDIS_PORT in .env file.
Change the following hosts in the .env and .env.test
- DB_HOST=localhost
- REDIS_HOST=localhost
Best way to run this project is to use the vscode Run and Debug button. Scripts are available for debugging and template generation on vscode.
- Install node.js and npm on your local machine.
# From the root of the project executes
$ npm install$ docker compose stop tester
$ docker compose stop app # production mode
$ npm start
or
# watch mode
$ npm run watch# unit and integration tests
$ npm test
