@fluid-tools/build-cli

flub is a build and release tool for the Fluid Framework GitHub repositories. flub is intended to replace the existing fluid build-tools, primarily by reusing existing build-tools functionality and wrapping it in a more consistent, maintainable CLI using oclif.

Command Topics

• flub ai - AI-powered assistant for launching the right AI agent.
• flub autocomplete - Display autocomplete installation instructions.
• flub build-perf - Build performance observability commands for collecting, processing, and analyzing build metrics.
• flub bump - Bump the version of packages, release groups, and their dependencies.
• flub check - Check commands are used to verify repo state, apply policy, etc.
• flub commands - List all flub commands.
• flub exec - Run a shell command in the context of a package or release group.
• flub generate - Generate commands are used to create/update code, docs, readmes, etc.
• flub help - Display help for flub.
• flub info - Get info about the repo, release groups, and packages.
• flub list - List packages in a release group in topological order.
• flub merge - Sync branches depending on the batch size passed
• flub modify - Modify commands are used to modify projects to add or remove dependencies, update Fluid imports, etc.
• flub promote - Promote commands are used to promote packages published to an npm registry.
• flub publish - Publish commands are used to publish packages to an npm registry.
• flub release - Release commands are used to manage the Fluid release process.
• flub rename-types - Renames type declaration files from .d.ts to .d.mts.
• flub report - Report analysis about the codebase, like code coverage and bundle size measurements.
• flub transform - Transform commands are used to transform code, docs, etc. into alternative forms.
• flub typetests - Updates configuration for type tests in package.json files. If the previous version changes after running preparation, then npm install must be run before building.
• flub vnext - Vnext commands are new implementations of standard flub commands using new infrastructure.

Developer notes

This package outputs its build files to lib/ instead of dist/ like most of our other packages. The reason is that oclif uses the lib folder by convention, and there are oclif bugs that can be avoided by putting stuff in lib. See the PR here for an example: https://github.com/microsoft/FluidFramework/pull/12155

Testing

The release command provides a testMode flag, which subclasses are expected to check when handling states. If in test mode, all handled states should immediately return true. This enables tests to verify that new states are handled in some way. Other commands could adopt this, but only the release command uses it today.

The release command also provides a state flag that can be used to initialize the state machine to a specific state. This is intended for testing.

Manual Integration Testing and Debugging

There are some VS Code launch targets like flub generate typetests that may work in some cases.

To run a locally built version of flub in contexts where the invocation of flub is done via package.json scripts, use a pnpm override. For client that is:

            "@fluid-tools/build-cli": "file:./build-tools/packages/build-cli",
            "@fluidframework/build-tools": "file:./build-tools/packages/build-tools",
            "@fluid-tools/version-tools": "file:./build-tools/packages/version-tools"

This approach can be used with flub generate typetests to ensure that the --entrypoint configuration, if any, from the scripts is included, and can be done from a JavaScript Debug console to debug, though breakpoints will need to be set in the .js files in node_modules (for example in node_modules/.pnpm/file+build-tools+packages+build-cli_@[email protected]/node_modules/@fluid-tools/build-cli/lib/commands/generate/typetests.js).

Alternatively, link: overrides give similar results and are known to support setting breakpoints directly in .ts files. When using link: be sure dependencies in build-tools are installed. See pnpm.ic documentation for more information.

            "@fluid-tools/build-cli": "link:./build-tools/packages/build-cli",
            "@fluidframework/build-tools": "link:./build-tools/packages/build-tools",
            "@fluid-tools/version-tools": "link:./build-tools/packages/version-tools"

Either pattern requires pnpm i --no-frozen-lockfile after setting overrides. If any build-tools package dependencies are updated when using file:, be sure to rerun for both workspaces.
