update-v4 schematic writes @angular-architects/native-federation-v4-v4/config into federation.config.mjs

[Ionaru]

Summary

ng g @angular-architects/native-federation-v4:update-v4 <project> rewrites the federation config's import to @angular-architects/native-federation-v4-v4/config (note the doubled -v4), which does not resolve. The build then fails with Cannot find package '@angular-architects/native-federation-v4-v4' until the import is corrected by hand.

Affected versions

• @angular-architects/native-federation-v4@20.4.3 (dist-tag v20-support)
• @angular-architects/native-federation-v4@21.2.8 (dist-tag latest)

Both ship the identical code path.

Cause

src/schematics/update-v4/schematic.js:

const V3_PACKAGE = '@angular-architects/native-federation';
const V4_PACKAGE = '@angular-architects/native-federation-v4';
// ...
content = content.replace(new RegExp(escapeRegExp(V3_PACKAGE + '/config'), 'g'), V4_PACKAGE + '/config');
content = content.replace(new RegExp(escapeRegExp(V3_PACKAGE) + '(?!/)', 'g'), V4_PACKAGE);

The first replacement produces @angular-architects/native-federation-v4/config. The second then matches the @angular-architects/native-federation prefix inside that result: its (?!/) lookahead only guards against a following /, and the next character here is -. So it substitutes a second time, giving @angular-architects/native-federation-v4-v4/config.

Reproduction

1. An Angular 20 workspace on @angular-architects/native-federation v3 with a CommonJS federation.config.js.
2. npm i -D @angular-architects/native-federation-v4@20.4.3
3. ng g @angular-architects/native-federation-v4:update-v4 <project>

Generated federation.config.mjs:

import { withNativeFederation } from '@angular-architects/native-federation-v4-v4/config';

Expected: @angular-architects/native-federation-v4/config.

Suggested fix

Make the second replacement skip an already-substituted prefix, for example by widening the lookahead to (?!\/|-v4), or by running the bare-package replacement before the /config one so the two cannot compound.
