local-cors-proxy-bun

A Bun CORS proxy for local development.

Install

bun add local-cors-proxy-bun

CLI

bunx local-cors-proxy-bun --port 8010 --origin "*" --credentials

| Flag | Short | Default | Description | | --------------- | ----- | ------- | ------------------------------------------ | | --port | -p | 8010 | Port to listen on | | --origin | -o | * | Access-Control-Allow-Origin value | | --credentials | -c | false | Include Access-Control-Allow-Credentials |

Environment variables (PORT, ORIGIN, CREDENTIALS) work too — flags take priority.

Programmatic

import { createProxy } from "local-cors-proxy-bun";

const server = createProxy({ port: 8010, origin: "*", credentials: false });

// server is a Bun.Server instance
server.stop();

Usage

https://localhost:{port}/{encoded URL to proxy}

Prefix any encoded URL with the proxy address.

The proxy strips host, origin, and referer headers, follows redirects, and adds CORS headers to the response.

e.g.

http://localhost:8010/https%3A%2F%2Fapi.example.com%2Fdata
