How to remove all console.log statements from your minified or combined javascript file

Question

Iam using Visual studio

Iam having javascript codes scattered in different files.

Currently iam using below link's compressor

this generates output as combined+minified files on project build.

i am looking for some way to remove all console.log statements from my codes in minified files. Please suggest me how to do this.

That won't help you, but ideally you would have a build script that only includes `console.log` in development mode. This could be done with e.g. ant and the C preprocessor (cpp). — Felix Kling, Jan 06 '11 at 15:38

Why not just do this:

window['console'] = { log: function() {} };

when you don't want the "console.log" statements to do anything?

Pointy

iam looking for some way in visual studio, too get rid of unnecessary code. Rather than doing this. A build event that would merge all files and get rid of console thing. – Praveen Prasad Jan 06 '11 at 15:56

OK, well I'm not a Visual Studio expert, so I regret that I cannot help with that. – Pointy Jan 06 '11 at 15:59

Manually, you can use your editor, such as Visual Studio and with Search and Replace functionality use RegEx to remove all of your console logs.

With regex such as this:

console\.log(\((\").*\"\);+|\((\').*\'\);+)

You will be able to match all console.logs with " or ' wrapping strings.

Then you replace then with empty string.

You have to select g flag, or GLOBAL option or Replace All button.

Also consider, that console object has multiple methods, such as dir, table, group, etc...
