🔧 ESLint#

A static code analysis tool for JavaScript and TypeScript. Catches bugs, enforces code style, and flags bad patterns — before you run the code.

📦 Install#

# Install locally in a project (recommended)
npm install --save-dev eslint

# Initialize config (interactive setup)
npx eslint --init

⚠️ As of ESLint v9, the config format changed from .eslintrc.* to eslint.config.js (flat config). Most tutorials online still show the old format — check the version.

🔧 Husky#

A tool that makes git hooks easy to share across a team. Hooks are stored in the repo (.husky/) and automatically activated when anyone runs npm install — no manual git config needed.

📦 Install#

npm install --save-dev husky
npx husky init

husky init does two things:

Adds a prepare script to package.json
Creates a default .husky/pre-commit file

✅ Core Use Cases#

Run linters before every commit (e.g. markdownlint, ESLint)
Run tests before pushing
Enforce commit message format (with commitlint)
Ensure no contributor can accidentally skip hooks — hook setup is automatic via npm install

🔑 Key Usage#

How it works#

git clone <repo>
cd <repo>
npm install
 └── triggers "prepare" script in package.json
 └── runs "git submodule update --init --recursive && husky"
 └── sets git core.hooksPath = .husky/_ automatically

No manual git config needed — ever.

🔧 markdownlint-cli2#

A fast CLI tool to lint Markdown files against a set of rules. Catches bad formatting, missing code block languages, trailing spaces, and inconsistent structure — before they reach GitHub.

📦 Install#

npm install --save-dev markdownlint-cli2

Requires Node.js. No global install needed — use via npx or npm run scripts.

✅ Core Use Cases#

Enforce consistent Markdown formatting across all .md files
Block bad commits via a git pre-commit hook (via Husky)
Fail CI/CD pipelines on unformatted Markdown
Auto-fix many common issues with --fix

🔑 Key Commands / Usage#

Check all Markdown files#

npm run lint:md
# or directly:
npx markdownlint-cli2 "**/*.md" "#node_modules" "#themes" "#public"

What it does: Scans all .md files, prints violations with file + line number.
