Hi all, I've pushed a commit that upgrades the Angular version from 7 to 9. At the same time, I've optimized the UI build process a bit: - Ahead-of-time compilation is activated - Optimizations (e.g., JS minification) are turned on - I switched the default build tool from custom webpack to angular-cli and modified the startup scripts in the package.json, so that "npm start" now triggers "ng serve" and "npm build" now triggers ng build. There is still a fallback to use the old custom webpack config by running npm start-webpack, once everything works, we can remove this later.
The changes should reduce the resulting JS bundle size quite significantly (~6MB for the whole bundle). However, I had to change quite a few things to get this working, e.g., old AngularJS modules had to be prepared for minification, incompatible libraries etc. I also turned on strictDi for AngularJS modules to better discover issues in the future. So although I checked and most things seem to work as expected, I'm quite sure we'll find some new bugs after this upgrade (Angular 9 now uses Ivy unter the hood, see https://angular.io/guide/ivy-compatibility). It would be great if you could check the whole UI to see if there's any unexpected behavior. At least one open issue I've discovered: - there's an open issue with plotly.js and Angular 9 (see https://github.com/plotly/angular-plotly.js/issues/75) , I changed the Plotly module to PlotlyViaCDNModule, but have not yet checked if this is working now Just reply to this mail in case you find any other issues!
