20 Common NodeJS tools / packages for your backend production app

Let's cut to the chase, if you're planning on building a production level backend NodeJS application, chances are you'll need all or most of these packages:

1.  Express or NestJS for backend API framework
2.  Node-convict and dotenv for configuration management
3.  Joi for API request validations or data validations
4.  Sequelize ORM for MySQL/Postgres databases, or Mongoose for MongoDb
5.  RabbitMQ for publishing/subscribing to message queues, or Kafka for streams and message brokers
6.  Ioredis / node-redis for caching with Redis
7.  Axios for handling third party API integrations. Need a good command of json API calls and response handling
8.  Bull queue or Faktory for delayed/background jobs
9.  Socket.io for real time peer to peer connections
10. Jest/Supertest for unit testing or integration testing and coverage reports
11. Winston / Morgan for logging (use morgan-body if you want to log request / response, useful for debugging in staging and dev environments)
12. Passport.js for authentication, or any custom authentication service using cookie-parser, jsonwebtoken or oath
13. Node-cron for cron jobs
14. Multer for handling file uploads
15. Swagger for OpenAPI documentation (swagger-ui-express or @nest/swagger)
16. Lodash for utilities
17. Luxon for date time manipulation, especially when dealing with timezones
18. ESLint + TSLint + Prettier for static code analysis and formatting
19. Husky for Git hooks
20. Docker for containerisation (Not NodeJS specific, but it helps)
