Sparo optimizes performance of Git operations for your large frontend monorepo.

Monorepo for Sparo toolkit

Sparo optimizes performance of Git operations for your large frontend monorepo.

Key features

• Familiar interface: The sparo command-line interface (CLI) wrapper offers better defaults and performance suggestions without altering the familiar git syntax. (The native git CLI is also supported.)

• A proven solution: Git provides quite a lot of ingredients for optimizing very large repos; Sparo is your recipe for combining these features intelligently.

• Simplified sparse checkout: Work with sparse checkout profiles instead of confusing "cones" and globs

• Frontend integration: Sparo leverages Rush and PNPM workspace configurations, including the ability to automatically checkout project dependencies

• Dual workflows: The sparo-ci tool implements a specialized checkout model optimized for continuous integration (CI) pipelines

• Extra safeguards: Avoid common Git mistakes such as checkouts with staged files outside the active view

• Go beyond Git hooks: Optionally collect anonymized Git timing metrics in your monorepo, enabling your build team to set data-driven goals for local developer experience (not just CI!)

  (Metrics are transmitted to your own service and are not accessible by any other party.)

For details, consult the Sparo documentation.
