Let’s begin with the basics. From Angular 6 upgrading Angular versions can be done with the cli. This makes life a lot easier:

ng update @angular/cli @angular/core

Rxjs

Angular 7 uses RxJS v6.3 so update RxJS:

ng update rxjs

Typescript

Angular 7 supports Typescript v3.1 so here we go again:

ng update typescript

Other libraries

  • codelyzer
  • ng-packagr
  • tslib
  • tsickle (had to be added)

TsLint plugin

This could be old news already, but we said goodbye to tslint-language-service and got typescript-tslint-pluginas our tslint plugin. Note that this has to be changed in the tsconfig.json.

Hope you got some valuable pointers for a smooth upgrade.
