How can I concatenate all JS files in a folder?

Question

I have a main app folder with many subfolders, each with their own subfolders, etc, which along the way contain .js files.

I want to create a grunt task that concatenates all the .js files anywhere under this main top level folder, which is called src.

Is there anyway to do that?

Right now, I have

            cwd: '.',
            src: [
                'src/**/**/*.js',
                'src/**/**/**/*.js',
                'src/**/**/**/**/*.js',
            ],
            dest: 'dist/app/superapp.js'

but this doesn't account for all possible .js file locations. And if I add a new .js in some folder, I don't want to have to manually update the grunt task.

Are all the files under `app` or `src`? If `src` you should only need the single `src/**/*.js` line to do the trick. — Andy, Apr 07 '15 at 12:05
maybe you're overdoing the wildcards, `**/*.js` should match any depth. — doldt, Apr 07 '15 at 12:05
@Andy good catch. I meant to say they're all under `src`. I edited — CodyBugstein, Apr 07 '15 at 12:16

According to the grunt docs, src/**/*.js is all you need here.

foo/**/*.js will match all files ending with .js in the foo/ subdirectory and all of its subdirectories.
