Run sass-convert in a node express service

[andersonbalves]

Hi guys!

Is there a way to run this lib in a express service?

I have to do a service to convert css codes to sass codes. I tried do make this but when I call the convert({from: 'css', to: 'sass'}) I get this following error:

events.js:187
      throw er; // Unhandled 'error' event
      ^
Error: spawn sass-convert ENOENT
    at Process.ChildProcess._handle.onexit (internal/child_process.js:264:19)
    at onErrorNT (internal/child_process.js:456:16)
    at processTicksAndRejections (internal/process/task_queues.js:80:21)
Emitted 'error' event on ChildProcess instance at:

    at processTicksAndRejections (internal/process/task_queues.js:80:21) {
  errno: 'ENOENT',
  code: 'ENOENT',
  syscall: 'spawn sass-convert',
  path: 'sass-convert',
  spawnargs: [ '--from=css', '--to=sass', '--stdin', '--no-cache' ]
}

My code:

app.post(["/v1/css-to-sass/"], (req, res) => {
    var inputStreamReq;

    req.pipe(req.busboy);
    req.busboy.on('file', function (fieldname, file, filename) {
      console.log("Uploading: " + filename);
      const name = uuidv1();
      inputStreamReq = fs.createWriteStream(__dirname + '/../model/' + name + '.css');
      file.pipe(inputStreamReq);

      inputStreamReq.on('close', () => {
        vfs.src(__dirname + '/../model/' + name + '.css')
          .pipe(converter({
            from: 'css',
            to: 'sass'
          }))
          .pipe(vfs.src(__dirname + '/../model/'));

        res.send('');

      });
    });

Hi @andersonbalves,

our sass-convert package is buggy and unmaintained. I would recommend not using it. It's trying to access the old Ruby Sass binary, which leads to several issues.

Thanks for the answer @pascalduez

So I'll try do use ruby-sass directly (hope it works hahaha).
