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

``sh
npm install @babel/core strip-debug
`

Usage

`js
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.

Ignoring specific lines

You can ignore specific statements from being stripped by using special comments:

`js
// strip-debug-ignore-next
console.log('This will NOT be stripped');

console.log('This will be stripped'); // strip-debug-ignore
`

Both comment styles work:
- // strip-debug-ignore-next - Ignores the next line
- // strip-debug-ignore - Ignores the current line (inline comment)
- / strip-debug-ignore-next /` - Block comment style also works
