This is a boilerplate application for building REST APIs in Node.js using ES6 and Express with Code Coverage and JWT Authentication. Helps you stay productive by following best practices. Follows Airbnb's Javascript style guide.
Heavily inspired from Egghead.io - How to Write an Open Source JavaScript Library.
| Feature | Summary |
|---|---|
| ES6 via Babel | ES6 support using Babel. |
| Authentication via JsonWebToken | Supports authentication using jsonwebtoken. |
| Code Linting | JavaScript code linting is done using ESLint - a pluggable linter tool for identifying and reporting on patterns in JavaScript. Uses ESLint with eslint-config-airbnb, which tries to follow the Airbnb JavaScript style guide. |
| Auto server restart | Restart the server using nodemon in real-time anytime an edit is made, with babel compilation and eslint. |
| ES6 Code Coverage via istanbul | Supports code coverage of ES6 code using istanbul and mocha. Code coverage reports are saved in coverage/ directory post yarn test execution. Open coverage/lcov-report/index.html to view coverage report. yarn test also displays code coverage summary on console. Code coverage can also be enforced overall and per file as well, configured via .istanbul.yml |
| Debugging via debug | Instead of inserting and deleting console.log you can replace it with the debug function and just leave it there. You can then selectively debug portions of your code by setting DEBUG env variable. If DEBUG env variable is not set, nothing is displayed to the console. |
| Promisified Code via bluebird | We love promise, don't we ? All our code is promisified and even so our tests via supertest-as-promised. |
| API parameter validation via express-validation | Validate body, params, query, headers and cookies of a request (via middleware) and return a response with errors; if any of the configured validation rules fail. You won't anymore need to make your route handler dirty with such validations. |
| Pre-commit hooks | Runs lint and tests before any commit is made locally, making sure that only tested and quality code is committed |
| Secure app via helmet | Helmet helps secure Express apps by setting various HTTP headers. |
| Uses yarn over npm | Uses new released yarn package manager by facebook. You can read more about it here |
- CORS support via cors
- Uses http-status to set http status code. It is recommended to use
httpStatus.INTERNAL_SERVER_ERRORinstead of directly using500when setting status code. - Has
.editorconfigwhich helps developers define and maintain consistent coding styles between different editors and IDEs.
Clone the repo:
git clone git@github.com:kunalkapadia/express-mongoose-es6-rest-api.git
cd express-mongoose-es6-rest-apiInstall yarn:
npm install -g yarnInstall dependencies:
yarnSet environment (vars):
cp .env.example .envStart server:
# Start server
yarn start
# Selectively set DEBUG env var to get logs
DEBUG=express-mongoose-es6-rest-api:* yarn startRefer debug to know how to selectively turn on logs.
Tests:
# Run tests written in ES6
yarn test
# Run test along with code coverage
yarn test:coverage
# Run tests on file change
yarn test:watch
# Run tests enforcing code coverage (configured via .istanbul.yml)
yarn test:check-coverageLint:
# Lint code with ESLint
yarn lint
# Run lint on any file change
yarn lint:watchOther gulp tasks:
# Wipe out dist and coverage directory
gulp clean
# Default task: Wipes out dist and coverage directory. Compiles using babel.
gulp# compile to ES5
1. yarn build
# upload dist/ to your server
2. scp -rp dist/ user@dest:/path
# install production dependencies only
3. yarn --production
# Use any process manager to start your services
4. pm2 start dist/index.jsIn production you need to make sure your server is always up so you should ideally use any of the process manager recommended here. We recommend pm2 as it has several useful features like it can be configured to auto-start your services if system is rebooted.
Universal logging library winston is used for logging. It has support for multiple transports. A transport is essentially a storage device for your logs. Each instance of a winston logger can have multiple transports configured at different levels. For example, one may want error logs to be stored in a persistent remote location (like a database), but all logs output to the console or a local file. We just log to the console for simplicity, you can configure more transports as per your requirement.
Logs detailed info about each api request to console during development.
Logs stacktrace of error to console along with other details. You should ideally store all error messages persistently.
Get code coverage summary on executing yarn test
yarn test also generates HTML code coverage report in coverage/ directory. Open lcov-report/index.html to view it.
# service restarts on file change
bash bin/development.sh# To use this option you need to make sure mongodb is listening on port 27017
# Build docker
docker build -t express-mongoose-es6-rest-api .
# Run docker
docker run -p 4040:4040 express-mongoose-es6-rest-apiIf you would prefer not to use any of our tooling, delete the following files from the project: package.json, gulpfile.babel.js, .eslintrc and .travis.yml. You can now safely use the boilerplate with an alternative build-system or no build-system at all if you choose.
