@zenclabs/api

A TypeScript-based DSL to generate API contracts (OpenAPI, Swagger, JSON Schema, API Blueprint), client SDKs (TypeScript, Swift, Kotlin) or even server boilerplate (e.g. Express).

Example of an API definition file api.ts which defines a single POST endpoint to create a user:

import { api, endpoint, request } from "@zenclabs/api";

@api()
class Api {
  @endpoint({
    method: "POST",
    path: "/users"
  })
  createUser(@request req: CreateUserRequest): CreateUserResponse {
    throw "contract";
  }
}

interface CreateUserRequest {
  firstName: string;
  lastName: string;
}

interface CreateUserResponse {
  success: boolean;
}

You can pass the definition above to a generator by simply running:

npx @zenclabs/api generate --api api.ts

This is work in progress as of 3 Nov 2018:

• [x] Functional TypeScript DSL
• [x] Support for multiple files (using import statements)
• [x] OpenAPI 3 generator
• [x] OpenAPI 2 generator
• [x] JSON Schema generator
• [ ] API Blueprint generator
• [x] TypeScript axios-based client generator
• [x] TypeScript express-based server boilerplate generator
• [ ] Swift client generator
• [ ] Kotlin client generator

• Usage
• Commands

Usage

To get started and set up an API declaration in the current directory, run:

npx @zenclabs/api init

You can then run a generator with:

npx @zenclabs/api generate --api api.ts

Commands

• api generate
• api help [COMMAND]
• api init

api generate

Runs a generator on an API. Used to produce client libraries, server boilerplates and well-known API contract formats such as OpenAPI.
