SyntaxError: Unexpected token 'const' -- despite the fact that I replaced const - node.js

Question

I'm trying to export my firebase app so I can call it inside of mocha test specs as well as within the source code I'm trying to test.
My Mocha test spec looks like this:
import Vue from 'vue'
import Edit from '#/components/Edit'
import filedata from '../../../static/filedata.js'
import submitFile from '../../../helpers/submitFile.js'
import firebaseapp from '../../../src/db.js'
var db = firebaseapp.database()
var storage = firebaseapp.storage()
describe('Edit.vue', () => {
it('should let me add files without choosing a category', () => {
// add files to appear on the homepage
var Constructor = Vue.extend(Edit)
var vm = new Constructor().$mount()
console.log(filedata + ' is the file data')
var ref = storage.ref('categories')
console.log(ref)
submitFile(filedata)
}) ...
And the submitFile file looks like this:
var firebaseapp = require('../src/db.js')
console.log('the app is: ' + firebaseapp)
var db = firebaseapp.database()
var storage = firebaseapp.storage()
module.exports = function(files){
// is the function being called from the test environment?
if(files){
console.log(files)
}
else {
// function called from src -- files were null
var files = this.$refs.upload.uploadFiles;
}
var storageRef = storage.ref();
var pdfsRef = storageRef.child('files');
// var self = this;
console.log('the files length is ' + files.length)
files.forEach(function(file){
var file = file['raw'];
var name = file['name']
var fileref = storageRef.child(name);
var uploadTask = fileref.put(file);
uploadTask.then(function(snapshot){
console.log('uploaded');
var url = snapshot.downloadURL;
self.gettext(url, name);
});
try {
uploadTask.on('state_changed', function(snapshot){
// Observe state change events such as progress, pause, and resume
// Get task progress, including the number of bytes uploaded and the total number of bytes to be uploaded
self.uploadProgress = (snapshot.bytesTransferred / snapshot.totalBytes) * 100;
console.log(self.uploadProgress + ' is the upload progress.');
switch (snapshot.state) {
case app.storage.TaskState.PAUSED: // or 'paused'
console.log('Upload is paused');
break;
case app.storage.TaskState.RUNNING: // or 'running'
console.log('Upload is running');
break;
}
}, function(error) {
// Handle unsuccessful uploads
}, function() {
// Handle successful uploads on complete
// For instance, get the download URL: https://firebasestorage.googleapis.com/...
var downloadURL = uploadTask.snapshot.downloadURL;
});
}
catch(e){
console.log(e)
}
})
}
Lastly, here's what db.js looks like:
var Firebase = require('firebase')//import Firebase from 'firebase'
var config = {
...
};
var app = Firebase.initializeApp(config) /// USED TO BE CONST APP
export default app
What's very strange is that when I run npm run unit, I get an error telling me that const is not recognized.
SyntaxError: Unexpected token 'const'
at webpack:///src/db.js~:11:0 <- index.js:38182
So I went through my db.js file and changed const to var, and I'm getting the exact same error*, no matter how I change the file.
Does anyone have any idea what could be going on?

Answer 1

From the looks of the error thrown, this seems like a problem with PhantomJS cache. Check this Stack Overflow post right here.
