Create awesome Express.js applications with best of breed tech including Typescript, structured logging with Pino, API validation and interactive documentation via an OpenAPI 3 or Swagger 2 spec, environment based config with dotenv.

generator-express-no-stress-typescript gets you up and running in seconds. It's ridiculously easy to configure. Heck, just take the defaults. Start it. Write code.

This generator scaffolds a fully functioning REST API server complete with interactive documentation, API validation, structured logging, environment driven config, and more. Simply run the generator and smile :-D

This project is a Typescript variant of generator-express-no-stress

Here's what you get!

What you get!

  • Typescript - Typescript is a typed superset of JavaScript that compiles to plain JavaScript
  • Express.js - Fast, unopinionated , minimalist web framework for Node.js
  • Pino - Extremely fast node.js logger, inspired by Bunyan. It also includes a shell utility to pretty-print its log files
  • dotenv - Loads environment variables from .env for nodejs projects
  • Swagger - is a simple yet powerful representation of your RESTful API.
  • SwaggerUI - dynamically generate beautiful documentation and sandbox from a Swagger-compliant API

API Validation

Simply describe your APIs with Swagger and automagically get for free:

  • Interactive documentation
  • API validation

Interactive API Doc

API Validation!

Oops! I the API caller forgot to pass a name field, no stress, we've got this!

Structured Logging

Structured logging out of the box!

raw

pretty

Structured logging pretty printed by default - great for dev!

API Validation Example

Simply describe your APIs with Swagger and automatically get:

  • API request validation
  • Interactive documentation

FAQ

Q: How do I modify the example API and make it my own?

A: There are two key files that enable you to customize and describe your API:

  1. server/routes.ts - This references the implementation of all of your routes. Add as many routes as you like and point each route your express handler functions.
  2. server/common/api.yaml - This file contains your OpenAPI spec. Describe your API here. It's recommended that you to declare any and all validation logic in this YAML. express-no-stress-typescript uses express-openapi-validator to automatically handle all API validation based on what you've defined in the spec.

Q: I previously generated an app, but I want to change the API root. How do I do this?

A: You need to make to small changes

  1. Modify server/routes.ts
   // Change your original path e.g. /api/v1/examples, to:
   app.use('/api/v2/examples', examplesRouter);
  1. Modify server/common/api.yaml and update the api root:
  # Change e.g. /api/v1 to /api/v2
  servers:
  - url: /api/v2
