Debug

Known issues

deprecatedJs2Py is in maintenance mode; no new features or major fixes. Consider alternatives like pyexecjs or Node.js subprocess for modern JavaScript.

fix

Use pyexecjs or call Node.js directly.

affects: >=0.74.0

gotchaES6+ features (e.g., arrow functions, const/let, classes) are not fully supported. May throw SyntaxError.

fix

Transpile modern JS to ES5 (using Babel) before passing to Js2Py.

affects: all

deprecatedThe top-level `require()` function is experimental and may not work with CommonJS modules.

fix

Prefer `EvalJs` with manual script loading.

affects: all
