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

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

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).

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.

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

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.

• 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.
