Local CORS Proxy

Simple proxy to bypass CORS issues. This was built as a local dev only solution to enable prototyping against existing APIs without having to worry about CORS.

This module was built to solve the issue of getting this error:

No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:3000' is therefore not allowed access. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disable

Getting Started

npm install -g local-cors-proxy

Simple Example

API endpoint that we want to request that has CORS issues:

https://www.yourdomain.ie/movies/list

Start Proxy:

lcp --proxyUrl https://www.yourdomain.ie

Then in your client code, new API endpoint:

http://localhost:8010/proxy/movies/list

End result will be a request to https://www.yourdomain.ie/movies/list without the CORS issues!

Alternatively you can install the package locally and add a script to your project:

 "scripts": {
   "proxy": "lcp --proxyUrl https://www.yourdomain.ie"
 }

Options

Option Example Default
--proxyUrl https://www.google.ie
--proxyPartial foo proxy
--port 8010 8010
--credentials (no value needed) false
--origin http://localhost:4200 *

env vars

It is possible to set custom cookies when doing upstream requests. Add the following to your .env file:

LCP_COOKIE=my_token=12312; sessionId=12313212
