    Class AngularConfigManager

    Manages modifications to an Angular project's angular.json file.

    Usage:

    const manager = new AngularConfigManager(repoRoot, clientPackagePath);
    if (!manager.Load()) return; // angular.json not found — skip silently

    manager.AddPrebundleExcludes(manifest);
    // future: manager.AddAssets(manifest);
    // future: manager.AddBuildOptions(manifest);

    const result = manager.Save();

    The class tracks whether any mutations actually changed the config. If nothing changed, Save() is a no-op (no unnecessary file writes).

    • Adds the app's npm scope(s) to serve.options.prebundle.exclude for all projects in angular.json. Idempotent: patterns already present are skipped.

            version?: string;
        }

      Returns number

      Number of patterns added (0 if all already present).

    • Loads and parses angular.json from the client workspace.

      Returns boolean

      true if the file was loaded successfully, false if angular.json doesn't exist (which is not an error — the project may not use Angular).

      If the file exists but can't be parsed as JSON.

    • Removes the app's npm scope(s) from serve.options.prebundle.exclude. Only removes patterns NOT used by any other installed app.
