Merge localBuild support into `firebase deploy` #9193

annajowang · 2025-09-26T13:19:28Z

Description

Process localBuild source deploys configs in firebase deploy for apphosting.

If localBuild is indicated in firebase.json, the deploy process will run a local apphosting build and upload the built app into a GCS bucket (instead of the entire source code).
Code to actually set localBuild in the user's firebase.json is not included here.

Scenarios Tested

firebase deploy --only apphosting
with apphosting { localBuild:true } in firebase.json.

The rollout is not expected to work on the backend yet, but a local build should be kicked off and the output should be successfully uploaded into buckets.

firebase deploy --only apphosting without localBuild continue to work.

- Adds `/firebase:init` prompt with placeholder guidance. - Resources are defined in `src/mcp/resources`. - Prompts and other output can "link" to resources by saying to use the `read_resources` tool with a particular URI. - Consolidates context into a single McpContext type. - Some additional refactoring and cleanup.

* feat(mcp): Combine auth_get_user and auth_list_users tools Combines the `auth_get_user` and `auth_list_users` MCP tools into a single `auth_get_users` tool. This new tool has two optional arguments, `uids` and `emails`. - When no arguments are provided, it behaves like `auth_list_users`. - When either `emails` or `uids` is provided, it looks up users by the provided identifiers. Removes unused variables and ensures that `passwordHash` and `salt` fields are consistently removed from all user objects returned by the tool. * Formats * Parallelize calls * Small fixes * npm format --------- Co-authored-by: google-labs-jules[bot] <161369871+google-labs-jules[bot]@users.noreply.github.com> Co-authored-by: Joe Hanley <[email protected]> Co-authored-by: Alexander Nohe <[email protected]>

This indicates that my refactoring did not break any existing functionality. I have created the new spec file at `src/mcp/tools/auth/update_user.spec.ts` with a basic test structure. I have added a comprehensive suite of tests to `src/mcp/tools/auth/update_user.spec.ts` to cover all the functionality of the new tool. * Cleaning up unit tests * Fixing tests * PR suggestions * PR fixes * Few changes * Name update * Name update --------- Co-authored-by: google-labs-jules[bot] <161369871+google-labs-jules[bot]@users.noreply.github.com> Co-authored-by: Joe Hanley <[email protected]> Co-authored-by: Alexander Nohe <[email protected]>

* feat: support preview releases in publish script The publish script has been updated to support a new 'preview' version. When releasing a preview version, the following changes occur: - A branch name must be provided, and the release will be built from that branch. - The npm package is published with a '--tag=preview' flag. - The following steps are skipped: - Pushing changes to the master branch. - Creating a GitHub release. - Generating firepit artifacts. - Generating a Docker image. * feat: include branch name in preview release version and tag Updates the preview release functionality to include the sanitized branch name in the npm prerelease version string and the npm distribution tag. This allows for multiple preview versions from different branches to coexist without conflicting. --------- Co-authored-by: google-labs-jules[bot] <161369871+google-labs-jules[bot]@users.noreply.github.com>

This commit renames the `experimental:mcp` command to `mcp` and adds an alias for the old name to maintain backward compatibility. All references to the old command name in the codebase have been updated. Additionally, the `isEnabled('mcp')` check has been removed, as the command is now stable. A changelog entry has been added for this change. Co-authored-by: google-labs-jules[bot] <161369871+google-labs-jules[bot]@users.noreply.github.com> Co-authored-by: Joe Hanley <[email protected]>

* feat: Add GA4 tracking for Gemini CLI extension This change adds a new parameter `gemini_cli_extension` to the MCP GA4 tracking when the `experimental:mcp` command is run. This parameter is set to "true" when the `IS_GEMINI_CLI_EXTENSION` environment variable is set, and "false" otherwise. This will allow us to track the usage of the Gemini CLI extension. * feat: Add GA4 tracking for Gemini CLI extension This change adds a new parameter `gemini_cli_extension` to the MCP GA4 tracking when the `experimental:mcp` command is run.

src/deploy/apphosting/prepare.ts

+    try {
+      const { outputFiles, annotations, buildConfig } = await localBuild(
+        options.projectRoot || "./",
+        "nextjs",


Is it noted anywhere to the user that only nextjs is supported? What happens if they try to deploy an Angular app

No, that's also why this feature is not exposed to the users anywhere yet. The original intention was to have this used exclusively by Studio first, so the nextjs hardcode is fine.

The underlaying local build CAN actually support angular, but the parsing of the build output to zip and upload to GCS needs tweaking to support angular.

We will also need the micro-discovery feature to tell the under-lying local build which adapter to run. This is very far from being done.

So the general steps of this work is:

get an MVP working that support nextjs for team testing

expand support beyond nextjs and MVP

document things when it's ready for users to use directly via the CLI
