SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

prek optimization helps teams tune pre-commit hook execution for faster, safer code checks by controlling how prek runs hooks in parallel and how much context is shared.

Core Features & Use Cases

  • Priority-based parallelism: groups hooks by priority to maximize throughput without sacrificing correctness.
  • pass_filenames tuning: adjust whether tools receive full project context or only changed files for faster runs.
  • Startup overhead reduction: minimize wrapper and environment startup costs for common tools.
  • Benchmarking & validation: provide workflows to measure performance, identify bottlenecks, and validate improvements.
  • Use Case: teams wanting faster CI pre-commit passes or developers seeking snappier local commits.

Quick Start

Run prek validate-config to verify your setup and then perform a dry-run to benchmark performance.

FAQPage Schema
How do I speed up pre-commit hooks for faster local commits?

Speed up pre-commit hooks by tuning prek parallelism with priority groups, adjusting pass_filenames to limit context, and reducing startup overhead. This configuration maximizes throughput without sacrificing correctness for snappier local commits.

What is pass_filenames tuning in pre-commit configurations?

pass_filenames tuning adjusts whether pre-commit tools receive full project context or only changed files. Adjusting this in prek minimizes shared context and reduces processing time for faster, safer code checks.

How do I benchmark pre-commit hook performance to identify bottlenecks?

Benchmark pre-commit hook performance by running prek validate-config to verify your setup, then executing a dry-run to measure performance and identify bottlenecks. This workflow ensures predictable, validated improvements.

Can I group pre-commit hooks by priority to maximize throughput?

Yes, you can group pre-commit hooks by priority using prek to maximize parallelism throughput. Priority-based parallelism coordinates multiple hooks efficiently without sacrificing correctness during execution.

Does prek hook optimization work for CI pipeline pre-commit passes?

prek hook optimization works for CI pipelines by tuning pre-commit hook execution for faster, safer code checks. Teams wanting faster CI pre-commit passes use priority groups and startup overhead management to achieve predictable results.
