Livewire 3 Upgrade Blocker Lint

Runs the same checker as the npm package @readystack/livewire3-upgrade-blocker-lint on a Node.js runtime that pip installs for you (nodejs-wheel-binaries) - no system Node.js needed. Your files are checked locally.

The Livewire 2 lines that die quietly in Livewire 3 — named, with the v3 replacement beside each

Install

livewire3-upgrade-blocker-lint file

Node 18+. The same 15 rules as the VS Code extension, from a terminal or CI.

Free

• Scan the .php or .blade.php file you have open and get every Livewire 3 blocker with its v3 replacement, line by line — no key, no watermark, no run limit.
• --rules lists every rule

With a licence ($29 once)

• Scan every .php and .blade.php in the workspace in one command and export an owned REPORT.md / JSON with file:line for the whole migration, plus a non-zero exit code for CI.
