Node Skeleton

A boilerplate to help start Node.js projects quickly and effectively. Packaged with Typescript, Docker, PM2, Eslint, VSCode config, Winston, Typedoc, Nodemon, AVA, PromClient, OpenAPI/Swagger, etc.

Motive behind this project

Having worked on a lot of node.js projects, I had to repetitively do the same tasks over and over again, get a project structure, install stuff, implement standardization, containerize it, implement logging, and make sure everything is in place before I start off. This takes all the burden out and lets people focus just on the logic and nothing else.

You can find the article I wrote on this project here: https://medium.com/techahoy/building-a-boilerplate-for-microservices-part-1-166ce00f5ce9

Basic Concepts behind the architecture

  1. All the code you write resides within src folder and gets built when you start the server in dist folder.
  2. All configuration is stored against the respective environment in src/config/env folder and .env file in the root.
  3. All your navigation routes are placed in src/app/routes folder. You can place as many js files as you want within.
  4. All your logic is written in controllers placed within src/app/controllers folder.
  5. If you have utility functions which you will use across controllers, put them in src/app/utils folder.
  6. All the server side rendered template files are to be placed in src/app/views folder.
  7. All your static files and content is to be placed in the public folder.

Deployment instructions

Normal Installation

  1. Install node.js and git
  2. Add them to path if not already in path.
  3. Install typescript globally with npm install typescript -g
  4. Run npm install to get all the dependencies installed
  5. cd to the project directory and run tsc to build using typescript
  6. Run npm run-script start-dev

Cloning & Running with Docker

  1. Install Docker and Docker Compose
  2. Clone/Download the repository and CD to it
  3. Run docker-compose up to get the containers installed and started.

Pulling & Running from Docker Hub

  1. Pull the container from DockerHub with the command docker pull tvvignesh/node-skeleton (Add version if you want)

  2. Then, start the container using the command: docker run -d -p 8085:8085 -p 9229:9229 -e NODEJS_PORT=8085 -e NODE_ENV=development -e NODEJS_IP=0.0.0.0 tvvignesh/node-skeleton

Running via PM2

  1. Install node.js and pm2
  2. CD to the pm2 directory
  3. Run pm2 start pm2-dev.json to start the development cluster

Building the code

  1. Run npm run build to build the typescript code, copy relevant files

Logging Middleware

Winston logging can be added by using the winston library. logger.log('error', 'Internal server error - ' + err.stack, err);

By default, logging occurs in console in the development environment and gets written to files within logs folder in other environments.

Static Files

You can place all your static files in the public directory and that will get served by the server directly

Exposing Metrics

The project is bundled with prom-client to enable exporting the metrics to prometheus with ease. You can access the default metrics at "/metrics" endpoint. You can modify what you export in src/app/controllers/metrics.server.controllers.ts

Linting

You can customize rules if needed using the .eslintrc file placed in the root directory. If you are using VSCode, you can have the ESLint extension installed. While linting is run everytime you build/start the server, you can manually run it by npm run lint

Generate API Documentation (OpenAPI/Swagger)

You can generate documentation site by providing details regarding all the endpoints in the apidoc.yaml file in the root and once done, you can start the server and your documentation will get exposed in /api-docs URL. You can use tools like OpenAPI GUI to help generate the YAML file for you.

Generate Code Documentation

You can generate documentation based on your code by running npm run document. Once generated, you can find the documentation in the docs folder. See this to know how to document your code to be rendered by the doc generator.

Running Tests

You can run your tests by using npm run test command. The project is bundled with AVA as the test framework.

Environmental Variables

You can set up the environmental variables in the .env file and that will get used in files like docker-compose, Dockerfile, etc. In addition to this, you can set up the rest of the environmental configurations in config/env/yourenv.ts where yourenv can be anything and the respective configs will get loaded depending on env you set.

Compatibility

Since this project uses all the latest features of the node ecosystem, it requires Node >= v10.0.0
