CORS Proxy

This is a simple proxy server that adds the necessary headers to allow Cross-Origin Resource Sharing (CORS) for a specified website.

Getting Started

These instructions will help get a copy of the CORS-Proxy up and running on a local machine for development and testing purposes.

Prerequisites

Node.js and npm are required for the proxy to run. They can downloaded from the official website or can be installed with a package manager like Homebrew (for macOS) or Chocolatey (for Windows).

Installation

1. Clone or download this repository.
2. Open a terminal and navigate to the root directory of the project.
3. Run npm install to install the required dependencies.

Running the Server

Run the following command to start the proxy server:

node index

The server will listen on port 3000 by default. To use a different port, pass the port as a parameter.

For example, to run the proxy server on port 3333, run the following command:

node index 3333

Usage

To use the proxy, simply make a request to localhost:<port>/proxy with the target URL as a header named 'Target-URL'. For example, to make a GET request to https://example.com/api/users, use the following URL:

http://localhost:3000/proxy/api/users

With the following header:

{ 'Target-URL': 'https://example.com' }

If using during development, a default URL can be set to avoid having to set the Target-URL header with every request.

For example, to set https://example.com/ as the default URL, pass the target URL as a parameter in the terminal:

node index 3000 https://example.com/

Note: if a Target-URL header is present in the request, it will override the default URL.

Limitations

• The proxy only supports HTTP and HTTPS requests.
• The proxy does not support websockets.
• The proxy does not support server-side rendering of client-side applications.
