Discussion on: Angular Ivy: a detailed introduction

[Lars Gyrup Brink Nielsen]

New finding: The ngComponentDef/ɵcmp key can be determined by importing ɵNG_COMP_DEF from @angular/core. So in version 8, ɵNG_COMP_DEF would evaluate to 'ngComponentDef' whereas it would evalute to 'ɵcmp' in Angular version 9.

There are similar key constants for directives, pipes, and Angular modules.

Really nice hint! I will have a look, I am working a post about compiler pipeline.

Oh dear, I just discovered that this export was called ɵNG_COMPONENT_DEF in Angular version 8, but is renamed to ɵNG_COMP_DEF in Angular version 9 😔
