This repo can be used as a starting point for backend development with Nodejs. It comes bundled with Docker and is CI/CD optimized. The development environment uses docker-compose to start dependent services like mongo. There is an action to review all PRs with ChatGPT.

A few things to note in the project:

• Github Actions Workflows - Pre-configured Github Actions to run automated builds and publish image to Github Packages.
• Dockerfile - Dockerfile to generate docker builds.
• docker-compose - Docker compose script to start service in production mode.
• Containerized Mongo for development - Starts a local mongo container with data persistence across runs.
• Safe Mongooose Connection Helper - A helper class to connect with Mongoose reliably.
• Joi - For declarative payload validation
• Middleware for easier async/await - Catches errors from routes and throws them to express error handler to prevent app crash due to uncaught errors.
• OpenAPI 3.0 Spec - A starter template to get started with API documentation using OpenAPI 3.0. This API spec is also available when running the development server at http://localhost:3000/dev/api-docs
• .env file for configuration - Change server config like app port, mongo url etc
• Winston Logger - Uses winston as the logger for the application.
• ESLINT - ESLINT is configured for linting.
• Jest - Using Jest for running test cases

$ bash <(curl -s https://raw.githubusercontent.com/sidhantpanda/public/master/scripts/generate-express-ts-app.sh)

$ git clone [email protected]:sidhantpanda/docker-express-typescript-boilerplate.git your-app-name
$ cd your-app-name

$ yarn install

$ yarn setup-actions

Starting the dev server also starts MongoDB as a service in a docker container using the compose script at docker-compose.dev.yml.

$ yarn dev

Running the above commands results in

• 🌏API Server running at http://localhost:3000
• ⚙️Swagger UI at http://localhost:3000/dev/api-docs
• 🛢️MongoDB running at mongodb://localhost:27017

The mongo container is only only available in dev environment. When you build and deploy the docker image, be sure to provide the correct environment variables.

$ yarn build && yarn start

$ docker build -t api-server .
$ docker run -t -i \
      --env NODE_ENV=production \
      --env MONGO_URL=mongodb://host.docker.internal:27017/books \
      -p 3000:3000 \
      api-server

$ docker-compose up

To edit environment variables, create a file with name .env and copy the contents from .env.default to start with.

The application uses winston as the default logger. The configuration file is at src/logger.ts.

• All logs are saved in ./logs directory and at /logs in the docker container.
• The docker-compose file has a volume attached to container to expose host directory to the container for writing logs.
• Console messages are prettified
• Each line in error log file is a stringified JSON.
