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!

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