Importing Leaflet Draw NGX for angular 4

Question

I followed the steps from the main git: https://github.com/Asymmetrik/ngx-leaflet

first I installed the required libraries (leaflet, leaflet-draw, leaflet-ngx, and leaflet-draw-ngx)

then I declared the required directive imports in app.module.

In my view I set the following:

<div class="col-md-6" style="height: 400px;"
         leaflet
         leafletDraw
         [leafletOptions]="options"
         [leafletLayers]="layers"
         [leafletLayersControl]="layersControl"
         [leafletDrawOptions]="drawOptions">
</div>

but I get the following error:

> Uncaught Error: Template parse errors:
Can't bind to 'leafletDrawOptions' since it isn't a known property of 'div'. ("fletDraw [leafletOptions]="options" [leafletLayers]="layers" [leafletLayersControl]="layersControl" [ERROR ->][leafletDrawOptions]="drawOptions"> </div> <div class="col-md-6"> <table class="table table-striped c"): ng:///gxxxx.html@0:258

    at JitCompiler._compileModuleAndComponents (compiler.es5.js?524d:26658)
    at JitCompiler.compileModuleAsync

I am new to angular 4, I'm I doing something wrong ? or is it related to ES version ?

Make sure you import the Leaflet and LeafletDraw modules into the module in which your component is defined (not just in AppModule).

In your AppModule.ts:

import { LeafletModule } from '@asymmetrik/ngx-leaflet';
import { LeafletDrawModule } from '@asymmetrik/ngx-leaflet-draw.module';
...
imports: [
    ...
    LeafletModule.forRoot(),
    LeafletDrawModule.forRoot()
]
...

In the component's module:

import { LeafletModule } from '@asymmetrik/ngx-leaflet';
import { LeafletDrawModule } from '@asymmetrik/ngx-leaflet-draw.module';
...
imports: [
    ...
    LeafletModule,
    LeafletDrawModule
]
...
