API Schema Generator

This npm package generates API endpoints and React hooks based on an OpenAPI schema, with TypeScript types for improved type safety and autocompletion. Built for use with fetch, it offers native, dependency-free HTTP requests.

Features

- API Endpoints: Generates endpoint functions with fetch implementation, providing a simple way to integrate APIs with native JavaScript methods.
- TypeScript Types: Automatically generates TypeScript types for API requests and responses based on the OpenAPI schema.
- React Hooks: Optional generation of React hooks, simplifying data fetching with hooks tailored to each endpoint.

Installation

Install the package via npm:

``bash
npm install openapi-fetch-gen
`

Usage

To generate API endpoints, TypeScript types, and React hooks (optional), use the CLI command:

`bash
node dist/cli.js -s schema.json -o generated --hooks react
`

$3

- -s, --schema: Path to the OpenAPI schema file (e.g., schema.json).
- -o, --output: Directory where the generated files will be saved.
- --hooks: Adds React hooks for each API endpoint (optional). Currently supports react.

$3

`bash
node dist/cli.js -s ./openapi-schema.json -o ./src/api --hooks react
`

Generated Files

- TypeScript Types: Strongly-typed request and response objects for each endpoint.
- API Endpoints: Functions using fetch to call each API endpoint.
- React Hooks: Optional React hooks for seamless API integration.

> Tip: Using TypeScript with this package enhances type safety and auto-completion, reducing errors and improving development speed.

Project Vision

This package is designed to bring type safety and streamlined API integration to the TypeScript and React ecosystem by utilizing OpenAPI schemas and native fetch` requests.
