Echo JS 0.11.0

You have different software to manage this.

1. the tracker script to embed into pages
2. the backend to digest the data and sort into the right storage per user.
3. the dashboard/app to look at collected data.

1: is just a little bit of javascript, no framework or stack needed, except for snowplow, to actually collect the data
2. you could use anything you are comfortable with, but for http routing with per-user authentication you could use nodejs, express, passport and db of your choice: nosql: mongo/mongoose or for sql: postgres or mysql with knex/bookshelf.
3. Use whatever you want to, react, vue or if you must angular.
There are good component presets like quasar.

Hello. 

Tracker? Send events?
You should be more precise about your product.
snowplow is a library to do analytics with their software.

What kind of tracker do you have and what events do you need to send?

Is it a complex logistics tracker of packages and you need to send push notifications? Be more concrete. The specific the better.

Is it a single page application? progressive web app? mobile hybird app?  What are the requirements.
You can slap any framework against any problem, but to really know your problems would be nice to be able to help.
Otherwise, pick what you want. Vue, React whatever. Both have good generation CLI tools to quickly get started. With the least amount of configuration setup required.

There is Promise.all though  ¯\_(ツ)_/¯

has this anything to do with javascript? I guess no.

EchoJS has also always been my favorite news feed, as an independent platform. :) So glad you are back

This is CSS task, not JS.

I can completely understand the authors problems.
I have always seen Angular as a tool, that tries to define how to deal with any situation (read enterprise). But once you need to go beyond the limits or how Angular has intended it for you, you begin to really struggle.

At least this guy is having the attention of the internet now :)

Less code equals bad UX. Of course, it is as easy as that to define the quality of a package.
