Below are some short tutorials that cover common tasks.

Custom route with parameters

In this tutorial, we are going to implement the following features:

• Update the Trashcan component to receive and log route parameters.
• Create a new route that points to the Trashcan component and uses the main layout.
• Create an action reference that allows redirecting to the new route.
• Create a button in the New menu that invokes an action.

Update src/app/components/trashcan/trashcan.component.ts and append the following code to the ngOnInit body:

import { ActivatedRoute, Params } from '@angular/router';

@Component({...})
export class TrashcanComponent {

    constructor(
        // ...
        private route: ActivatedRoute
    ) {}

    ngOnInit() {
        // ...

        this.route.params.subscribe(({ nodeId }: Params) => {
            console.log('node: ', nodeId);
        });
    }

}

The code above logs the current route parameters to the browser console and is proof the integration works as expected.

Next, add a new route definition as in the example below:

{
  "$schema": "../../../extension.schema.json",
  "$version": "1.0.0",
  "$name": "plugin1",

  "routes": [
    {
      "id": "custom.routes.trashcan",
      "path": "ext/trashcan/:nodeId",
      "component": "your.component.id",
      "layout": "app.layout.main",
      "auth": ["app.auth"]
    }
  ]
}

The template above creates a new route reference with the id custom.routes.trashcan that points to the ext/trashcan/ route and accepts the nodeId parameter.

Also, we are going to use the default application layout (app.layout.main) and authentication guards (app.auth).

Next, create an action reference for the NAVIGATE_ROUTE application action and pass route parameters: /ext/trashcan for the path, and 10 for the nodeId value.

{
    "$schema": "../../../extension.schema.json",
    "$version": "1.0.0",
    "$name": "plugin1",

    "routes": [...],

    "actions": [
        {
            "id": "custom.actions.trashcan",
            "type": "NAVIGATE_ROUTE",
            "payload": "$(['/ext/trashcan', '10'])"
        }
    ]
}

Finally, declare a new menu item for the NEW button and use the custom.actions.trashcan action created above.

{
    "$schema": "../../../extension.schema.json",
    "$version": "1.0.0",
    "$name": "plugin1",

    "routes": [...],
    "actions": [...],

    "features": {
        "create": [
            {
                "id": "custom.create.trashcan",
                "type": "default",
                "icon": "build",
                "title": "Custom trashcan route",
                "actions": {
                    "click": "custom.actions.trashcan"
                }
            }
        ]
    }
}

Now, if you run the application, you should see a new menu item called "Custom Trashcan Route" in the "NEW" dropdown. Upon clicking this item you should navigate to the /ext/trashcan/10 route containing a Trashcan component.

Check the browser console output and ensure you have the following output:

node:  10

You have successfully created a new menu button that invokes your custom action and redirects you to the extra application route.

Dialog actions

In this tutorial, we are going to create an action that invokes a custom material dialog.

Please read more details on Dialog components here: Dialog Overview

Create a dialog

ng g component dialogs/my-extension-dialog --module=app

Update my-extension-dialog.component.ts:

import { Component } from '@angular/core';
import { MatDialogRef } from '@angular/material/dialog';

@Component({
  selector: 'aca-my-extension-dialog',
  templateUrl: './my-extension-dialog.component.html',
  styleUrls: ['./my-extension-dialog.component.scss']
})
export class MyExtensionDialogComponent {
  constructor(public dialogRef: MatDialogRef<MyExtensionDialogComponent>) {}
}

Update my-extension-dialog.component.html:

<h2 mat-dialog-title>Delete all</h2>
<mat-dialog-content>Are you sure?</mat-dialog-content>
<mat-dialog-actions>
  <button mat-button mat-dialog-close>No</button>
  <!-- The mat-dialog-close directive optionally accepts a value as a result for the dialog. -->
  <button mat-button [mat-dialog-close]="true">Yes</button>
</mat-dialog-actions>

Create an action

Append the following code to the src/app/store/actions/app.actions.ts:

export const SHOW_MY_DIALOG = 'SHOW_MY_DIALOG';

export class ShowMydDialogAction implements Action {
  readonly type = SHOW_MY_DIALOG;
}

Create an effect

Update src/app/store/effects/app.effects.ts:

import { ShowMydDialogAction, SHOW_MY_DIALOG } from '../actions/app.actions';

@Injectable()
export class AppEffects {
  constructor(...) {}

  @Effect({ dispatch: false })
  showMyDialog$ = this.actions$.pipe(
    ofType<ShowMydDialogAction>(SHOW_MY_DIALOG),
    map(() => {})
  );

  // ...
}

Update to raise a dialog

import { MatDialog } from '@angular/material/dialog';
import { MyExtensionDialogComponent } from '../../dialogs/my-extension-dialog/my-extension-dialog.component';

@Injectable()
export class AppEffects {
  constructor(
    ...,
    private dialog: MatDialog
  ) {}

  @Effect({ dispatch: false })
  showMyDialog$ = this.actions$.pipe(
    ofType<ShowMydDialogAction>(SHOW_MY_DIALOG),
    map(() => {
      this.dialog.open(MyExtensionDialogComponent)
    })
  );

  ...

}

Register a toolbar action

Update the src/assets/app.extensions.json file, and insert a new entry to the features.toolbar section:

{
  ...,

  "features": {
    "toolbar": [
      {
        "id": "my.custom.toolbar.button",
        "order": 10,
        "title": "Custom action",
        "icon": "extension",
        "actions": {
          "click": "SHOW_MY_DIALOG"
        }
      }
    ]
  }
}

Now, once you run the application, you should see an extra button that invokes your dialog on every click.
