How to upload multiple images to Sails.js application - node.js

Question

Backstory
I'm building an online marketplace for used cars where owners can list their cars for sale and buyers can find affordable used cars more easily.
I'm using Sails.js v1.0 as my app's Node.js framework.
Challenge
I want users to be able to add images to each car they've listed, Craigslist-style.
Current Implementation
Here's what I have thus far...
In images.ejs view file I have an ajax-form element:
<ajax-form class="" action="images" :syncing.sync="syncing" :cloud-error.sync="cloudError" #submitted="submittedForm()" :handle-parsing="handleParsingForm" enctype="multipart/form-data">
<div class="form-outer flex justify-center items-center h-100 bt bw2">
<div class="form-inner bg-yellow pa3 w-100">
<div class="mb3 w-100">
<label class="db tl mv2 f4" for="upload">Upload</label>
<input class="pv3" id="upload" type="file" :class="[formErrors.upload ? 'is-invalid' : '']" v-on:change>
<div class="bg-light-red light-gray pa2 br2 mt1" v-if="formErrors.upload">Please select at least one image.</div>
</div>
<p class="bg-light-red light-gray pa2 br2 mt1" v-if="cloudError"><small>An error occured while processing your request. Please check your information and try again, or contact support if the error persists.</small></p>
<div class="">
<ajax-button :syncing="syncing" class="bg-green pa2 ba b--dark-gray br2 bw1 b circular-bold">Add images.</ajax-button>
</div>
</div>
</div>
</ajax-form>
This form submits to the controller at POST: cars/images.js:
module.exports = {
friendlyName: 'Images',
description: 'Allow users to upload images of car.',
inputs: {
},
exits: {
},
fn: async function (req, res) {
req.file('upload').upload({
// don't allow the total upload size to exceed ~10MB
maxBytes: 10000000
},function whenDone(err, uploadedFiles) {
if (err) {
return res.serverError(err);
}
// If no files were uploaded, respond with an error.
if (uploadedFiles.length === 0){
return res.badRequest('No file was uploaded');
}
// Get the base URL for our deployed application from our custom config
// (e.g. this might be "http://foobar.example.com:1339" or "https://example.com")
var baseUrl = sails.config.custom.baseUrl;
// Save the "fd" and the url where the upload for a user can be accessed
User.update(req.session.userId, {
// Generate a unique URL where the upload can be downloaded.
uploadUrl: require('util').format('%s/user/upload/%s', baseUrl, req.session.userId),
// Grab the first file and use it's `fd` (file descriptor)
uploadFd: uploadedFiles[0].fd
})
.exec(function (err){
if (err) return res.serverError(err);
return res.ok();
});
});
}
};
This controller/sails action is using the standard req/res objects within the Sails.js actions2 format.
All of the Sails documentation on file uploads points to the Sails body-parser implementation called Skipper, but I feel the documentation is lacking on the new actions2 syntax.
Can anyone point me to a concrete example of implementing this file upload feature, especially for uploading multiple image files?
