How to include a file upload control in an Angular2 reactive form?

Question

For some weird reason, there are just no tutorials or code samples online showing how to use Angular2 Reactive forms with anything more than simple input or select dropdowns

Answer 1

I'm a bit late to this, but for anyone else that may come here looking for the same solution - This is my file input accessor that can be used with Reactive or Template-driven forms. Demo here.

There's some optional validation provided with it that can be used to check image dimensions and file size, extension, type, which is disabled by default.

npm i file-input-accessor and add the module to your AppModule imports:

import {BrowserModule} from '@angular/platform-browser';
import {FileInputAccessorModule} from "file-input-accessor";

@NgModule({
    declarations: [
        AppComponent
    ],
    imports: [
        BrowserModule,
        FileInputAccessorModule
    ],
    providers: [],
    bootstrap: [AppComponent]
})
export class AppModule {}

Then use your file input like any other input:

You can subscribe to valueChanges property just like any other reactive control.
