How do I set the Skipper body Limit in SailsJS v1.0? - sails.js

Question

I am currently having an issue when uploading files bigger then 10mb. I am uploading them to an s3 bucket.
I have tried to set the limit within the skipper that gets built in the middleware with the bodyparser.
order: [
'cookieParser',
'session',
'myRequestLogger',
'bodyParser',
'compress',
'poweredBy',
'router',
'www',
'favicon',
],
myRequestLogger: function (req, res, next) {
sails.log("Requested :: ", req.method, req.url);
return next();
},
/***************************************************************************
* *
* The body parser that will handle incoming multipart HTTP requests. *
* *
* https://sailsjs.com/config/http#?customizing-the-body-parser *
* *
***************************************************************************/
bodyParser: (function _configureBodyParser() {
var skipper = require('skipper');
var middlewareFn = skipper({
strict: true,
limit: '50mb'
});
return middlewareFn;
})(),
This doesn't seem to be using the limit property being set at all.
Any advice on this would help.

I'm not entirely sure where you found the limit option for Skipper, but limiting the file size of an upload is kinda documented between skipper-s3 the skipper.
Specifying the maxBytes option when receiving the upload in your action/controller should work.
If you're going to be uploading files to multiple actions/controllers then I'd keep the max file size somewhere like sails.config.custom.maxUploadFilesize so there's a single place to configure it - couldn't find any global Skipper options but I could have missed it.
const MAX_UPLOAD_BYTES = 10 * 1024 * 1024;
req.file('avatar')
.upload({
// Required
adapter: require('skipper-s3'),
key: 'thekyehthethaeiaghadkthtekey',
secret: 'AB2g1939eaGAdesoccertournament',
bucket: 'my_stuff',
maxBytes: MAX_UPLOAD_BYTES
}, function whenDone(err, uploadedFiles) {
if (err) {
return res.serverError(err);
}
return res.ok({
files: uploadedFiles,
textParams: req.params.all()
});
});
