The local proxy is not loading the central package -> proxy.conf.mjs needs to be updated

[berndu]

Hi

I have started testing the inheritance of the Central package in the June release.
The first thing I noticed was that when I use the local proxy, the Central Package does not load.

I investigated this and found:

bootstrap-config.ts
const url = ${prefix}/custom/${dashedVid}/CENTRAL_CODE.txt;
const xhr = new XMLHttpRequest();
xhr.open('GET', url, false); // 🔒 sync: finishes before Angular
xhr.setRequestHeader('Cache-Control', 'no-cache');
xhr.send(null);
if (xhr.status >= 200 && xhr.status < 300) {
nzVid = (xhr.responseText || '').trim();
}

But http://localhost:4201/nde/custom/41SLSP_ETH-ETH_CUSTOMIZING/CENTRAL_CODE.txt results in http 404

I added to the \proxy\proxy.conf.mjs another context:
{
context: [
'/nde/custom/*/CENTRAL_CODE.txt'
],
target: PROXY_TARGET,
secure: true,
changeOrigin: true,
logLevel: 'debug',
},

and CP was loaded.

Pls update your conf.

Best

And another context...

Otherwise Central Package /assets/css/custom.css is replaced by local assets/css/custom.css :(

41SLSP_NETWORK-CENTRAL_PACKAGE has to be replaced by something more generic.

context: [
'/nde/custom/41SLSP_NETWORK-CENTRAL_PACKAGE/**'
],
target: PROXY_TARGET,
secure: true,
changeOrigin: true,
logLevel: 'debug',
},

The issue is in proxy.conf.mjs.

What is wrong

Your current proxy rules include:

• a generic local handler for '/nde/custom/**'
• a local asset rewrite for '/nde/custom/*/assets/**'

That means:

• GET /nde/custom/.../CENTRAL_CODE.txt is caught by the local rule and not proxied, so it returns 404
• GET /nde/custom/.../assets/css/custom.css is rewritten to local /assets/css/custom.css, replacing the Central Package asset with the local one

---

What to change

Add an explicit proxy rule before the generic '/nde/custom/**' rule:

{
  context: [
    '/nde/custom/*/CENTRAL_CODE.txt',
    '/nde/custom/*/assets/**'
  ],
  target: PROXY_TARGET,
  secure: true,
  changeOrigin: true,
  logLevel: 'debug',
}

Use a wildcard path instead of the hard-coded package name 41SLSP_NETWORK-CENTRAL_PACKAGE.

Why this fixes it

Proxy rules are matched in order:

1. Specific Central Package routes should be proxied to PROXY_TARGET
2. Only then should the generic local /nde/custom/** fallback apply

That ensures:

• CENTRAL_CODE.txt is fetched from the backend, not blocked
• Central package asset requests are proxied correctly instead of rewritten to the local app

---

Recommended update

In proxy.conf.mjs, move or insert the new rule above:

{
  context: [
    '/nde/custom/*/CENTRAL_CODE.txt',
    '/nde/custom/*/assets/**'
  ],
  target: PROXY_TARGET,
  secure: true,
  changeOrigin: true,
  logLevel: 'debug',
},

Then keep the existing generic local rule after it.

If you want, I can also give you the exact patched block for proxy.conf.mjs.
