babel-plugin-remove-use-strict

library1.0.1jsnpmunverified

A Babel plugin that removes all `"use strict"` directives from JavaScript code. Version 1.0.1 is the current stable release; the package has minimal updates and is essentially feature-complete. It is a niche utility for projects where strict mode is unwanted (e.g., legacy code, certain bundling scenarios). Unlike manual regex-based removal, this plugin integrates directly into the Babel pipeline and respects AST, avoiding false positives in string literals or comments.

Verified usage

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

default

✓ module.exports = { plugins: ["remove-use-strict"] }

✗ import removeUseStrict from 'babel-plugin-remove-use-strict'

This is a Babel plugin, not a JavaScript export. It's used via Babel config, not imported directly.

plugin name string

✓ "remove-use-strict"

✗ "babel-plugin-remove-use-strict"

In .babelrc or babel.config.js, you specify the short name 'remove-use-strict' (without the 'babel-plugin-' prefix).

require("@babel/core").transform

✓ require("@babel/core").transform(code, { plugins: ["remove-use-strict"] })

✗ require("@babel/core").transform(code, { plugins: [require("babel-plugin-remove-use-strict")] })

When using Node API, the plugin is referenced by string name, not required as a module.

Shows basic Babel config and the effect of removing 'use strict' directives from code.

// .babelrc { "plugins": ["remove-use-strict"] } // Input "use strict"; function f() { "use strict"; console.log("use strict"); } // Output function f() { console.log("use strict"); }

Debug

Known issues

gotchaString literals containing 'use strict' (e.g., in console.log) are NOT removed.

fix

The plugin only removes directive nodes; ensure you understand the AST distinction.

affects: <=1.0.1

gotchaThe plugin is designed for Babel 6/7; compatibility with Babel 8 is untested.

fix

Test with your Babel version; consider contributing if issues arise.

affects: >=1.0.0

gotchaRemoving 'use strict' may change module behavior in ES modules or Node.js; it's not polyfilled.

fix

Only use if you understand the implications of disabling strict mode globally.

affects: >=1.0.0

Errors

Common errors & fixes

Error: Could not find plugin 'babel-plugin-remove-use-strict'. Ensure it is installed.

Missing npm install or incorrect plugin name.

fix

Run 'npm install babel-plugin-remove-use-strict' and use short name 'remove-use-strict' in config.

SyntaxError: Unexpected token (1:1) while parsing "use strict"

Input code is not JavaScript (e.g., JSON) or has syntax error.

fix

Ensure input is valid JavaScript; the plugin works on AST, not raw text.

TypeError: this.Opportunities is not a function

Babel version mismatch (e.g., using Babel 6 plugin in Babel 7).

fix

Use a Babel 7 compatible version or fork the plugin.
