JS Licence Key Gate: GPL & Eval Keys

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

Handsontable, TinyMCE, CKEditor 5, FullCalendar, AG Grid, MUI X and Syncfusion licence keys in closed-source JS/TS

Install

js-licence-key-gate file

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

Free

• Check one open JS/TS file for GPL, evaluation and missing commercial licence keys, with the line and the fix
