Using jq and Prettier in a Hook for Windows users - lessons 19 | 20

[develad]

There is an error in the course videos for windows users in the PowerShell terminal in VScode.

THE FIX CODE IS:

"hooks": { "PostToolUse": [ { "matcher": "Write|Edit", "hooks": [ { "type": "command", "command": "jq -r '.tool_input.file_path' | tr -d '\\r' | { read -r fp; [[ \"$fp\" =~ \\.tsx?$ ]] && npx prettier --write \"$fp\"; } 2>/dev/null || true" } ] } ] }

What changed from the original version:

• tr -d '\r' → -replace '\r','' — strips carriage return characters natively in PowerShell
• read -r fp → direct variable assignment
• 2>/dev/null || true → PowerShell silently ignores errors by default; you can add -ErrorAction SilentlyContinue if needed

And for Ubuntu, I had to use

"hooks": {
    "PostToolUse": [
      {
        "matcher": "Write|Edit",
        "hooks": [
          {
            "type": "command",
            "command": "jq -r '.tool_input.file_path' | xargs -I{} bash -c '[[ \"{}\" =~ \\.tsx?$ ]] && npx prettier --write \"{}\"'"
          }
        ]
      }
    ]
  }
