Overview

This file extends common/hooks.md with web-specific hook recommendations.

Web Hooks

Recommended PostToolUse Hooks

Prefer project-local tooling. Do not wire hooks to remote one-off package execution.

Format on Save

Use the project's existing formatter entrypoint after edits:

{
  "hooks": {
    "PostToolUse": [
      {
        "matcher": "Write|Edit",
        "command": "pnpm prettier --write \\"$FILE_PATH\\"",
        "description": "Format edited frontend files"
      }
    ]
  }
}

Equivalent local commands via yarn prettier or npm exec prettier -- are fine when they use repo-owned dependencies.

Lint Check

{
  "hooks": {
    "PostToolUse": [
      {
        "matcher": "Write|Edit",
        "command": "pnpm eslint --fix \\"$FILE_PATH\\"",
        "description": "Run ESLint on edited frontend files"
      }
    ]
  }
}

Type Check

{
  "hooks": {
    "PostToolUse": [
      {
        "matcher": "Write|Edit",
        "command": "pnpm tsc --noEmit --pretty false",
        "description": "Type-check after frontend edits"
      }
    ]
  }
}

CSS Lint

{
  "hooks": {
    "PostToolUse": [
      {
        "matcher": "Write|Edit",
        "command": "pnpm stylelint --fix \\"$FILE_PATH\\"",
        "description": "Lint edited stylesheets"
      }
    ]
  }
}

PreToolUse Hooks

Guard File Size

Block oversized writes from tool input content, not from a file that may not exist yet:

{
  "hooks": {
    "PreToolUse": [
      {
        "matcher": "Write",
        "command": "node -e \\"let d='';process.stdin.on('data',c=>d+=c);process.stdin.on('end',()=>{const i=JSON.parse(d);const c=i.tool_input?.content||'';const lines=c.split('\\\
').length;if(lines>800){console.error('[Hook] BLOCKED: File exceeds 800 lines ('+lines+' lines)');console.error('[Hook] Split into smaller modules');process.exit(2)}console.log(d)})\\"",
        "description": "Block writes that exceed 800 lines"
      }
    ]
  }
}

Stop Hooks

Final Build Verification

{
  "hooks": {
    "Stop": [
      {
        "command": "pnpm build",
        "description": "Verify the production build at session end"
      }
    ]
  }
}

Ordering

Recommended order:

  1. format
  2. lint
  3. type check
  4. build verification
