Incorporating Electron Modules into an Angular 2 TypeScript App

I am working on transforming Angular 2's 5 Minute Quickstart tutorial into an Electron app by incorporating "electron-prebuilt".

https://i.sstatic.net/wLfJy.png

However, I am facing limitations in utilizing some of Electron's advanced features, such as writing to the file system.

Although I can successfully build and run "Electrogram", I encounter an error when attempting to use certain basic functionalities within my Electron application:

Modified app.component.ts

import { Component } from '@angular/core';
import { remote, ipcRenderer } from 'electron';
import { writeFile } from 'fs';

@Component({
  selector: 'my-app',
  template: '<h1>My First Angular 2 App</h1><button (click)="doSomething()">Do Something</button>'
})
export class AppComponent {

  doSomething() {
    writeFile("c:\temp\doSomething.txt", "some data");
  }
}

Error Message in DevTools Console

I need guidance on configuring the app to correctly locate the Electron modules. How can this be achieved?

Answer №1

Dealing with differences in module loaders, I have encountered a similar issue before. Depending on the method of app construction, I implement different solutions.

Using Webpack:

Webpack consolidates all modules and dependencies into a single resulting app.js file (depending on configuration). When using import { readFile } from 'fs', everything functions smoothly. The demo application Electrogram utilizes webpack for this purpose.

In my opinion, this approach is the most efficient and quickest way to build the app, delivering optimal performance at runtime.

SystemJs Method:

If SystemJS serves as the module loader, then the following lines are necessary to load the FS module:

let remote = require('electron').remote;
let fs = remote.require('fs');
...
let data = fs.readFileSync(this.dbFilename);

I hope this explanation proves beneficial.

(PS. Do I comprehend every detail of this? Not entirely...)
