Breaking Changes

Added a new required appsOutDir option to the apolloClientAiApps Vite plugin

The apolloClientAiApps Vite plugin now requires an appsOutDir option that controls where build output is written. The value must end with apps as the final path segment (e.g. "dist/apps").

apolloClientAiApps({ targets: ["mcp"], appsOutDir: "dist/apps" });

The plugin will now write the application manifest to <appsOutDir>/<appName>/.application-manifest.json, where appName is taken from the name field in your apollo-client-ai-apps config or package.json. Previously, the output location was derived from build.outDir in your Vite config. Setting build.outDir alongside this plugin will now emit a warning that it is ignored.

This option replaces build.outDir. Setting build.outDir now emits a warning and the value is ignored. To migrate, please move the path from build.outDir to the appsOutDir option in the apolloClientAiApps plugin.

// vite.config.ts
export default defineConfig({
- build: {
-   outDir: "../../apps",
- },
  plugins: [
    apolloClientAiApps({
      targets: ["mcp"],
+     appsOutDir: "../../apps" ,
    }),
  ],
});
