Just go to tsconfig.json and set

"strictPropertyInitialization": false
to get rid of the compilation error.

Otherwise you need to initialize all your variables which is a little bit annoying

error TS2564: Property 'description' has no initializer and is not definitely assigned in the constructor. in angular class

Comment

  id!: number;

got it, it's because typescript 2.7.2 included a strict class checking where all properties should be declared in constructor. So to work around that, just add a bang sign (!) like: name!:string;
