Basic CI: Lint → Test → Build

Automate quality gates with a tiny CI: run lint, run tests, then build. Fail fast, keep logs readable, and cache dependencies.

Basic CI: Lint → Test → Build is a free React Academy lesson on CoddyKit — lesson 3 of 3. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the React Academy learning path, one of 3 lessons in the course, and your progress syncs across the web and the CoddyKit app.

Why CI?

Goal: Automate checks on every push.

  • Lint: fast static checks
  • Test: behavior safety
  • Build: optimized output

Steps at a glance

  • Trigger: push/PR
  • Install deps (cache)
  • Run lint → run tests → build
  • Artifacts: build folder, test report

Demo: Lint step

Lint is fast and fails early; fix style/errors before heavy work.

<div id="root"></div>

Demo: Test step

Tests confirm behavior; keep them small and fast in CI.

<div id="root"></div>

Demo: Build step

Build produces optimized assets; only run after lint+tests succeed.

<div id="root"></div>

Tips & checklist

  • Fail fast: lint → tests → build
  • Cache dependencies
  • Keep logs short; surface failures clearly
  • Store build artifacts for preview
