Summary of Changes

Hello @joehan, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a new dataconnect:compile command to the Firebase CLI, enhancing the developer experience for Firebase Data Connect users. This command automates the crucial steps of validating Data Connect schemas and generating client SDKs, ensuring that Data Connect services are correctly configured and ready for use. It provides a streamlined way to manage the compilation lifecycle of Data Connect projects.

Highlights

  • New CLI Command: A new firebase dataconnect:compile command has been added to the Firebase CLI.
  • Data Connect Compilation: This command is designed to compile Data Connect schema, connector configurations, and GQL files.
  • Targeted Compilation: The command supports optional --service and --location flags, allowing users to compile specific Data Connect services.
  • Compilation Process: The compilation process involves two main steps: building (validating schemas/connectors and generating .dataconnect metadata) and generating SDKs.

Code Review

This pull request introduces a new dataconnect:compile command. This command provides a way to compile Data Connect services, which includes building schemas and connectors and generating typed SDKs. The implementation correctly reuses existing logic from the deploy and SDK generation commands. My review includes a couple of suggestions to improve the clarity and correctness of the new command's implementation, such as updating the command description to be more comprehensive and clarifying a parameter passed to a shared function.

type CompileOptions = Options & { service?: string; location?: string };

export const command = new Command("dataconnect:compile")
.description("compile your Data Connect schema and connector config and GQL files.")

The command's description is slightly incomplete. In addition to compiling schema and connector files, the command also generates typed SDKs via DataConnectEmulator.generate. To avoid user surprise and accurately reflect the command's full functionality, I recommend updating the description.

Suggested change
.description("compile your Data Connect schema and connector config and GQL files.")
.description("compile your Data Connect schema and connector config, generate GQL files, and generate typed SDKs.")

options.nonInteractive,
options.force,

For clarity and to avoid potential confusion, it's better to pass false directly for the dryRun parameter, as this command doesn't support a --dry-run option. Using !!options.dryRun could be misleading for future maintenance, as it implies that dryRun might be a valid property on the options object.

Suggested change
!!options.dryRun,
false,
