Background

There's a lot of tech debt across TIS. In FE this is the case too.

Over time, some FE devs have tried to address the tech debt, with varying degrees of success and completion.

The result is an FE beast with duplicated elements in places, that need converging into one agreed solution, and multiple areas where the codebase needs bringing up the date (e.g. Angular 5 Apps containing non-Angular 5 code, and other Apps that aren't yet Angular 5 that need re-writing with Angular 5)

Relevant data

Things that need addressing are:

  1. Different versions of Angular in use
  2. Removal of dependency on jHipster scaffolding
  3. Aligning the filing structure to match best practice for Angular 5
  4. Tidy up the SCSS folder and code
  5. Where to apply global and local styles
  6. Tidying up of a plethora of tests and test approaches
  7. NGRX - observable

Options considered


Option 1:Option 2:Option 3:
Bringing all elements in TIS up to the same, current version of AngularV5V6

V7

Pros and cons

(plus) Admins UI is v5 and the biggest element of TIS. Getting everything to v5 would mean we could then upgrade all of TIS to later versions of Angular more easily

(minus) v5 is already 2 full versions behind the current stable version of Angular (v7). Admins UI contains lots of non-Angular v5 code within it that will need to be converted to Angular v5 first

(plus) More modern version of Angular opens up new features and addresses issues from v5

(minus) No element is using Angular v6 yet, so bringing all of TIS up to v6 is a huge task

(plus) More modern version of Angular opens up new features and addresses issues from v6
