Angular 6 library pipe
How to add a custom pipe in an Angular 6 library in order for it to be available in my main app ?
Currently I'm doing this in:
lib.module.ts:
@NgModule({
declarations: [
SomePipe
],
exports: [
SomePipe
]})
in public_api.ts:
export * from './lib/pipes/some.pipe';
in app.module.ts:
import { LibModule } from 'lib';
@NgModule({
...
imports: [
LibModule
]
...
})
I'm trying to use the pipe {{ 'something' | some}} but transform method of SomePipe is not called.

So the issue appears to be here:
export * from './lib/pipes/some.pipe';
You are exporting everything from some.pipe file when you should have exported the module(@NgModule) from the module file. Something like this:
export * from './lib.module';
Doing that should fix the issue.
Here's a Sample StackBlitz for your ref.

The export export * from './lib/pipes/some.pipe'; is correct because my pipe implementation resides in some.pipe.ts file.

The custom pipe was added correctly, and was working in my application. There was another bug that I did not manage to see, regarding a service (imported incorrectly from the library) that my @Pipe was using inside the transform() method. Therefore, transform() always appeared to return nothing, because it was relying on that service.
