stripify

Browserify transform that strips console.log lines from your code.

This module for browserify will remove console.log, console.info, console.warn, console.error, debugger and friends from your js files.

Example

For example.js:

var foo = "bar"
console.log(foo + " bar")
foo = "foo"

then on the command line:

browserify -t stripify example.js > bundle.js

or with the api:

var browserify = require("browserify")
  , fs = require("fs")
 
var b = browserify("example.js")
b.transform("stripify")
 
b.bundle().pipe(fs.createWriteStream("bundle.js"))

the bundle file output is:

var foo = "bar"
 
foo = "foo"

Usage

npm install stripify

As with all browserify transforms, stripify returns a through/transform stream.

var fs = require("fs")
  , stripify = require("stripify")
  , src = "/path/to/file.js"
  , dest = "/path/to/file-transformed.js"
  , ts = stripify(src)
 
fs.createReadStream(src).pipe(ts).pipe(fs.createWriteStream(dest))

Command line

You can use stripify on the command line as well:

npm install -g stripify
stripify /path/to/file.js

Output is written to stdout.

Options

--replacement=STATEMENT, -r STATEMENT

Stripify will remove console.log statements by default. If you've put a log statement in a weird place, removing it could cause a syntax error. The replacement option allows you to specify a replacement statement.

e.g.

echo "console.log('foo')" | stripify -r '(0)' # Outputs (0) 

browserify main.js -t [stripify -r '(0)']

var stripify = require("stripify")
stripify("file.js", {replacement: '(0)'})
