DEV Proxy Minimal Reproducable Example

MRE for unjs/nitro#1643

Problem

Nitro devProxy drops basepath of proxied server (only accepts Protocol, Host and Port of URL)

Config

{
    devProxy: {
        "/api": {
           target: "http://localhost:3001/api"
        }
    }
}

Expected

http://nitro:3000/api/foo => http://server:3001/api/foo

Observed

http://nitro:3000/api/foo => http://server:3001/foo

MRE

api_srv

Simple HTTP Server listening on 3001 responding with api_path: ${req.url}

httpxy_mre ✔️

Simple HTTP Server elevating httpxy to server /api via Proxy

nitor_mre ❌

Nitro stater sample, with devProxy

Changes

1. add proxy2 to httpxy_mre
   • /foo as entrypoint
   • initialize directly on proxy creation (similar to nitro dev/server.ts)
2. add /foo to nitro devProxy
3. add /bar to httpxy_mre
   • acutally httpxy is ignoring the path
   • nitro is just dropping the path of the route
