Angular - Electron interface fails to reflect updated model changes

Whenever I click on a field that allows me to choose a folder from an electron dialog, the dialog opens up and I am able to select the desired folder. However, after clicking okay, even though the folder path is saved in my model, it does not immediately show up in the input field. The path only appears when I click outside the field causing it to lose focus. How can I fix this behavior?

The template includes:

<input type="text" class="form-control" (click)="onClickPath($event)" [(ngModel)]="currentConfiguration.workspacePath" id="workspace-path" name="workspace-name" aria-label="workspace" aria-describedby="workspace-lable">

CurrentConfiguration.ts

export class CurrentConfiguration {
    workspacePath: string;
}

configuation.component.ts

currentConfiguration: CurrentConfiguration = {
    workspacePath: ""
};

//onClickedPath event: 

onClickPath(event) {
    console.log("clicked: ", event.target.id);

    // open the dialog to select the directory
    const dir = this.electronService.remote.dialog.showOpenDialog({
        properties: ["openDirectory"],
        title: event.target.id.split('-').join(" ")
    }, (folderPath) => {
        console.log(folderPath);

        if (folderPath[0] == undefined) {
            this.electronService.remote.dialog.showMessageBox({
                type: "error",
                buttons: ["ok"],
                title: "Error",
                message: "Please select the folder"

            });
        }
        else{
            // set the correct directoryPath. 
            this.currentConfiguration[event.target.id.split('-')[0] + 'Path'] = folderPath[0];
        }
    });

}

Answer №1

Important - Although similar to this question on StackOverflow, I found a solution that worked for me and wanted to share.

It appears that Electron dialogs operate outside of the Angular zone, causing data updates to not trigger a view refresh in Angular.

To force a refresh, I had to ensure my logic ran within a zone, as shown below:

import { NgZone } from '@angular/core';
...
...
currentConfiguration: CurrentConfiguration = {
        workspacePath: ""
    };

// onClickedPath event:

onClickPath(event) {
            console.log("clicked: ", event.target.id);

            // open the dialog to select the directory
            const dir = this.electronService.remote.dialog.showOpenDialog({
                properties: ["openDirectory"],
                title: event.target.id.split('-').join(" ")
            }, (folderPath) => {
                console.log(folderPath);

                if (folderPath[0] == undefined) {
                    this.electronService.remote.dialog.showMessageBox({
                        type: "error",
                        buttons: ["ok"],
                        title: "Error",
                        message: "Please select the folder"

                    });
                }
                else{
                   // run all of this inside the zone
                   this.zone.run(() => {
                    // set the correct directoryPath.
                    this.currentConfiguration[event.target.id.split('-')[0] + 'Path'] = folderPath[0];
                    }); // end of zone
                }

            });

        }
