The Typescript API framework that boosts developer productivity

Bridge is a strongly typed framework that auto-generates the OpenAPI specification and fully-typed Typescript client code, without schema or .

Simplicity

Bridge offers an easy and scalable way to write your backend code.

Create an endpoint

an intuitive way to write and to manage your endpoints.

Validate your data

Bridge supports query, body and headers validation using zod, yup or superstruct.

Add middlewares

Create powerful type-safe middlewares that can validate data, and pass data to next middlewares.

Experience the power of TS

Catch error ahead of time and improve your productivity using IDE’s autocompletion.

index.ts

import { initBridge, handler, apply, httpError } from 'bridge';
import z from 'zod'

const authMid = handler({
   headers: z.object({ token: z.string() }),
   resolve: (data) => {

(parameter) data: {
  headers: {
    token: string;
  };
}

     if (data.headers.token !== 'private_token') 
        return httpError(401, 'Wrong token');
      else return { name: 'John Doe' };
    },
})

const getMe = handler({

   body: z.object({ pseudo: z.string().min(3) }),

   middlewares: apply(authMid),

   resolve: () => 'Hello!'

(parameter) data: {
  body: {
    pseudo: string;
  };
  mid: {
    name: string;
  };
  headers: {
    token: string;
  };
}

   resolve: (data) => `Hey ${data.body.pseudo}`

})

const bridge = initBridge({ routes: { getMe } });

bridge.HTTPServer().listen(8080, () => {
    console.log("Listening on port 8080"); 
});

Never write HTTP requests again

Use your server's route like functions.

Goodbye Postman collections

The client SDK contains all the information necessary to integrate and use correctly your API.

Easily maintain and update your code

After an update, the IDE alerts developers of changes that happened in the API, and identifies where changes need to be made in the client code.
