Strip console, alert, and debugger statements from JavaScript code

strip-debug

Strip console, alert, and debugger statements from JavaScript code

Useful for making sure you didn't leave any logging in production code.

Usage

npm install @babel/core strip-debug

Usage

import {transformSync} from '@babel/core';
import stripDebug from 'strip-debug';

transformSync('function foo(){console.log("foo");alert("foo");debugger;}', {
	plugins: [stripDebug]
}).code;
//=> 'function foo() { void 0;void 0; }'

To prevent any side-effects, console.*/alert* is replaced with void 0 instead of being stripped.

If you shadow the console global with your own local variable, it will still be removed.
