In Angular8 defineInjectable was renamed to ɵɵdefineInjectable and defineInjectable was deprecated. This makes pre-8 libraries compatible with v8, however v8 compiled libraries will not be compatible with pre-8 consumers.

So, We should compile with Angular 7 and release it as compatible version for Angular 6 and 7.
Angular 8 compiled library will be compatible with Angular 8 + projects

@udayvunnam when will this fix be available? I am using ng7 and i am getting this error. Not sure how to fix.

[udayvunnam]

Hi @lenichols the fix is already available. Please use xng-breadcrumb@2.1.2 for Angular 6.x and 7.x

Compatibility versions: https://github.com/udayvunnam/xng-breadcrumb#compatiblity-table

The issue is because of a breaking change from @angular/core in version 8. If you ever upgrade your project to Angular 8+, use xng-breadcrumb@3.x instead
