Local Automation Pipeline

Automated local-first verification and artifact generation toolchains.

TECHNOLOGY:Node.jsGit HooksZshESLint
01 // WHY I BUILT IT

Manual CI runs on remote servers often create slow feedback cycles for solo builders. I needed instantaneous local validation before pushing commits.

02 // THE HYPOTHESIS & IDEA

Create zero-overhead git pre-commit and pre-push scripts that check TypeScript types, modified file linting, and asset bundle sizes in under 2 seconds.

03 // WHAT I TRIED

Configured Git hooks with parallelized check execution using native Node.js child processes and ripgrep.

04 // WHAT WORKED

Staging-only checks executed in under 1.4 seconds, catching type errors before git pushes occurred.

05 // WHAT FAILED

Running full end-to-end browser tests on every commit was too slow and caused workflow friction.

06 // KEY LEARNINGS

Tiered validation works best: instant type/lint on pre-commit, full static build check on pre-push.

07 // EXPERIMENTAL RESULT

Standardized automation toolchain now adopted across all JTM Labs active projects.

08 // NEXT ITERATION

Package the pipeline into an open-source CLI utility for quick reuse.

## Laboratory Notes This toolchain was developed to keep software development feedback loops fast and reliable on local developer machines. ### Workflow Hierarchy - **Tier 1 (Pre-commit / ~1.5s)**: Staged file linting, TypeScript declaration check, formatting integrity. - **Tier 2 (Pre-push / ~5s)**: Full production build compile, route resolution check, static asset integrity.
