Creating a JSON File using Ionic

I am currently working on an Ionic Application and my goal is to store data in a JSON file.

For creating the file, I execute the following code snippet:

this.file.writeFile(this.file.dataDirectory, 'test.json', 'hello,world,', {replace: true});

Unfortunately, the above code doesn't seem to be working as expected. The test.json file is not being created!

What could possibly be causing this issue?

EDIT: I recently received advice that I might need to incorporate cordova into my project. Can anyone elaborate on what that entails?

EDIT: Could it be because I am unable to locate "this.file.dataDirectory"?

PS: I have been executing (ionic cordova run browser) to run my script. Is there a chance that this method is causing complications?

In addition, even after implementing Melchia's suggestion, I am still not seeing any output in the console.log!

Answer №1

To add the cordova file plugin to your project, execute the following command:

$ ionic cordova plugin add cordova-plugin-file
$ npm install --save @ionic-native/file

Once the plugin's package is installed, include it in your app's NgModule.

import { File } from '@ionic-native/file';


...

@NgModule({
  ...

  providers: [
    ...
    File
    ...
  ]
  ...
})
export class AppModule { }

In your page.ts file, include the following code:

import { File } from '@ionic-native/file';

constructor(private file: File) { }


this.file.writeFile(this.file.dataDirectory, 'test.json', 'hello,world,', {replace: true}).then(_ => console.log('Directory exists')).catch(err => console.log('Directory doesn\'t exist'));

When working with Ionic V4, it's recommended to utilize the import { File } from '@ionic-native/file/ngx'; for managing files.
