Update to latest quasar version:

npm i -g @quasar/cli@latest

Lessons Learned

The best approach is to use Firestore directly in the app without a nodejs backend for most things. Vuexfire seems to be a good candidate to abstract a lot of hassle away for this.

Backend Query from .vue File:

methods: {
getPosts() {
.get(`${process.env.API}/posts`, {
headers: { Authorization: this.$q.localStorage.getItem("token") },
.then((resp) => {
this.posts = resp.data;
.catch((error) => {
if (error.response) {
if (error.response.status == 403) {
this.$router.push("/auth").catch((err) => {console.log(err)});

When commiting to git, include .postcssrc.js manually or the quasar app will break.

JS Promises

A more elegant way to write asynchronous functions without using .then and .catch is this format:

const funcName = async() => {
const a = getA()
const b = getB()
const c = await Promise.all([a,b])
return c

You could also await getA() and getB() separately, but they would not execute in parallel like in the example. This is useful if the value of B depends on A.
