Grunt and Async Writing

[jlbrooks]

When attempting to run css-modulesify as a browserify transform through Grunt using Grunt-browserify, an output file is generated but there is nothing written to it.

Digging into the code, I believe the issue is with the final asynchronous write here. As noted in the Grunt docs, Grunt is synchronous by default and requires you to register an async task and notify when finished. I have confirmed that changing the async write to be fs.writeFileSync(cssOutFilename, css); solves the issue.

Because this is embedded as a plugin within browserify, which is then run through the grunt-browserify plugin, I don't see an easy way to configure this correctly. Has anyone else been able to get this plugin working with a Grunt build? I'm fairly inexperienced with Grunt, so I could definitely be missing something obvious.

I've put together an example repo here. Running grunt browserify should generate the empty css file.

As far as solutions go, possibly a flag to force a synchronous write? That is, if there isn't something else I'm missing.
