typera

Features

• A purer approach to building your apps: Each route handler is an async function that takes a request and returns a response
• Automatically parses request inputs like route params, query params, headers and request body into typed values
• Infer the types of responses (status code, body, headers), allow type checking them according to your expectations
• Middleware are fully typed. This means that you no longer have to guess what's available in req, or whether a middleware short-circuits and returns a response. Instead, everything is type checked
• It's straightforward to start adding fully typed routes to an existing Express or Koa app. Old routes can be migrated gradually
• Built-in support for automatically generating an OpenAPI definition from your app with typera-openapi
