better-firebase-functions-esbuild

esbuild plugin for optimizing Firebase Cloud Functions builds. Version 7.1.1 is the latest stable, released April 2026, requiring Node >=20 and esbuild >=0.17.0. It provides per-function entry point generation with tree shaking by executing the BFF entry point in a discovery mode, automatically reusing runtime config (functionDirectoryPath, searchGlob, etc.) so no duplicate configuration is needed. Published weekly, it supports buildFunctions() as the recommended API, along with manual discovery helpers and a logging plugin. Differentiates from vanilla esbuild by automating the discovery of Firebase function files and maintaining the output directory structure matching the runtime layout.
