Alexandre Rafalovitch commented on SOLR-12196:
----------------------------------------------
My feeling is that "if not now" will be "close to never". Because it was a huge
effort to move it to Angular 1 and some bits were not even finished for very
long time (ever?). So, let's say another 3 years before anybody will raise this
conversation with the same amount of "sunk costs" as right now.
As to how/who, yeah, that's the big issue. Has been, it seems for a long time.
I am interested in learning React but I am not a frontend dev myself to take a
lead. And certainly not a visual designer, which is the hairy part... But my
feeling is that maybe it is worth asking on the dev list as a tradeoff
discussion.
> Prepare Admin UI for migrating to Angular.io
> --------------------------------------------

> Key: SOLR-12196
> URL: https://issues.apache.org/jira/browse/SOLR-12196
> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Components: Admin UI
> Reporter: Jan Høydahl
> Priority: Major
> Labels: Angular, AngularJS, angular-migration
> Fix For: master (8.0)
>
>
> AngularJS is soon end of life, it [enters LTS in july
> 2018|https://docs.angularjs.org/misc/version-support-status], whereupon it
> will only receive fixes to serious bugs. Solr uses AngularJS 1.3 (the latest
> AngularJS will be 1.7).
> This issue is *not* for upgrading to Angular5/6, but to start preparing the
> existing UI for easier migration later on. See
> [https://angular.io/guide/upgrade].
> This JIRA will likely get multiple sub tasks such as
> * Change to [Folders-by-Feature
> Structure|https://angular.io/guide/upgrade#follow-the-angularjs-style-guide],
> i.e. mix html, css, js in a folder based on feature
> * Use a [Module
> Loader|https://angular.io/guide/upgrade#using-a-module-loader] like
> [Webpack|https://webpack.js.org/]
> * Use [Component
> Directives|https://angular.io/guide/upgrade#using-component-directives]
> (requires first move from AngularJS 1.3 to 1.5)
> The rationale for this lira is recognising how central the Admin UI is to
> Solr, not letting it rot on top of a dying framework. Better to start moving
> step by step and [perhaps write all new views in Angular
> 5|https://angular.io/guide/upgrade#upgrading-with-ngupgrade], than to fall
> further and further behind.
> This effort of course assumes that Angular.io is the path we want to go, and
> not React, VueJS or some other new kid on the block :)
