babel-plugin-transform-jscript

library6.22.0jsnpmunverified

Babel plugin that fixes buggy named function expressions in JScript (IE<=8). This is an older Babel 6 plugin (v6.22.0), part of Babel's preset-es2015. It wraps named function expressions in an IIFE to avoid JScript's incorrect hoisting behavior. Not needed for modern browsers or Node.js. The plugin has no active maintenance as Babel 6 is superseded by Babel 7+; alternatives include using @babel/preset-env with the 'ie' target.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

default

✓ import plugin from 'babel-plugin-transform-jscript'

✗ const plugin = require('babel-plugin-transform-jscript')

Babel 6 plugins are CommonJS, but import works with bundlers. For .babelrc, just use the string 'transform-jscript'.

Demonstrates how to enable the plugin via .babelrc and shows the transformation of a named function expression to an IIFE to fix JScript hoisting.

// .babelrc { "plugins": ["transform-jscript"] } // input.js var foo = function bar() {}; // output.js var foo = (function() { var bar = function() {}; return bar; })();

Debug

Known issues

deprecatedThis plugin is for Babel 6 only and is no longer maintained. Use @babel/preset-env with the 'ie' option instead.

fix

Upgrade to Babel 7+ and use @babel/preset-env targeting 'ie 8' or similar.

affects: >=6.0.0

gotchaThe plugin only transforms named function expressions with the 'var' assignment pattern. Other patterns like object property assignments are not handled.

fix

Ensure your code uses var foo = function bar() {} to be transformed.

Errors

Common errors & fixes

Cannot find module 'babel-plugin-transform-jscript'

Package not installed or Babel 7+ is used (plugin name changed).

fix

Run 'npm install babel-plugin-transform-jscript' for Babel 6, or use @babel/plugin-transform-jscript for Babel 7+ (if available) but it's likely not needed.

Error: Cannot find module 'babel-core' from '...'

Using Babel 6 API with Node API but babel-core not installed.

fix

Ensure 'babel-core' is installed: npm install babel-core
