Getting started with Angular FileManager component

This section explains how to create a simple File Manager component and its basic usage.

Prerequisites

To get started with File Manager component, ensure the compatible versions of Angular and Typescript.

  • Angular : 4+
  • Typescript : 2.6+

Setting up angular project

Angular provides the easiest way to set angular CLI projects using Angular CLI tool.

Install the CLI application globally to your machine by using following command.

npm install -g @angular/cli

To Create a new application, refer the below command

ng new syncfusion-angular-app

Navigate to the created project folder by using following command.

cd syncfusion-angular-app

Refer Syncfusion Angular Getting Started section to know more about setting up angular-cli project.

Adding Dependencies

The following list of dependencies are required to use the file manager component in your application.

|-- @syncfusion/ej2-angular-filemanager
    |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-layouts
    |-- @syncfusion/ej2-popups
    |-- @syncfusion/ej2-data
    |-- @syncfusion/ej2-inputs
    |-- @syncfusion/ej2-lists
    |-- @syncfusion/ej2-buttons
    |-- @syncfusion/ej2-splitbuttons
    |-- @syncfusion/ej2-navigations
    |-- @syncfusion/ej2-grids
    |-- @syncfusion/ej2-filemanager
  • Install Syncfusion file manager package using below command.
npm install @syncfusion/ej2-angular-filemanager --save

The above package installs File Manager component dependencies which are required to render the component in an Angular environment.

Adding style sheet to the application

To render the file manager component, import the file manager and its dependent component’s styles as given below in [src/styles.css].

@import '../node_modules/@syncfusion/ej2-base/styles/material.css';
@import '../node_modules/@syncfusion/ej2-inputs/styles/material.css';
@import '../node_modules/@syncfusion/ej2-popups/styles/material.css';
@import '../node_modules/@syncfusion/ej2-buttons/styles/material.css';
@import '../node_modules/@syncfusion/ej2-splitbuttons/styles/material.css';
@import '../node_modules/@syncfusion/ej2-navigations/styles/material.css';
@import '../node_modules/@syncfusion/ej2-layouts/styles/material.css';
@import '../node_modules/@syncfusion/ej2-grids/styles/material.css';
@import '../node_modules/@syncfusion/ej2-angular-filemanager/styles/material.css';

Note: To refer the combined component styles, use Syncfusion CRG (Custom Resource Generator) in your application.

Adding File Manager module

After installing the package, the file manager component module is available to configure into your application from installed syncfusion package.

Refer to the following snippet to import the file manager module in app.module.ts from the @syncfusion/ej2-angular-filemanager.

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';

import { AppComponent } from './app.component';

// Imported syncfusion filemanager module from filemanager package
import { FileManagerModule } from '@syncfusion/ej2-angular-filemanager';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    HttpModule,

    // Registering EJ2 filemanager Module
    FileManagerModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Adding Syncfusion component

Add the FileManager component snippet in app.component.html as follows.

<ejs-filemanager id='default-filemanager' [ajaxSettings]='ajaxSettings'>
</ejs-filemanager>

Refer the FileManager component snippet in app.component.ts as follows.

import { Component } from '@angular/core';
@Component({
  selector: 'app-root',
  styleUrls: ['app/app.component.css'],
  templateUrl: 'app/app.component.html'
})
export class AppComponent {
  public hostUrl: string = 'https://ej2-aspcore-service.azurewebsites.net/';
  public ajaxSettings: object = {
    url: this.hostUrl + 'api/FileManager/FileOperations'
  };
}

Note: The ajaxSettings must be defined while initializing the file manager. File manager utilizes the URL’s mentioned in ajaxSettings to send file operation request to the server. The File Manager service link is given in hostUrl.

Run the application

Use the npm run start command to run the application in the browser.

npm start

The following samples shows the basic file manager component in browser.

File Download support

To perform the download operation, initialize the downloadUrl property in a ajaxSettings of File Manager component.

import { Component } from '@angular/core';
@Component({
  selector: 'app-root',
  styleUrls: ['app/app.component.css'],
  templateUrl: 'app/app.component.html'
})
export class AppComponent {

  public ajaxSettings: object = {
    url: this.hostUrl + 'api/FileManager/FileOperations',
    downloadUrl: this.hostUrl + 'api/FileManager/Download'
  };
}

File Upload support

To perform the upload operation, initialize the uploadUrl property in a ajaxSettings of File Manager Component.

import { Component } from '@angular/core';
@Component({
  selector: 'app-root',
  styleUrls: ['app/app.component.css'],
  templateUrl: 'app/app.component.html'
})
export class AppComponent {
  public hostUrl: string = 'https://ej2-aspcore-service.azurewebsites.net/';
  public ajaxSettings: object = {
    url: this.hostUrl + 'api/FileManager/FileOperations',
    uploadUrl: this.hostUrl + 'api/FileManager/Upload'
  };
}

Image Preview support

To perform the image preview support in the File Manager component, need to initialize the getImageUrl property in a ajaxSettings of File Manager component.

Injecting feature modules

Basically, the file manager component contains a context menu for performing file operations, large-icons view for displaying the files and folders, and a breadcrumb for navigation. However, these basic functionalities can be extended by using the additional feature modules like toolbar, navigation pane, and details view to simplify the navigation and file operations within the file system. The above modules can be injected into file manager by importing them as providers in app.module.ts.

Refer the code snippet in for app.module.ts.

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FileManagerModule, NavigationPaneService, ToolbarService, DetailsViewService } from '@syncfusion/ej2-angular-filemanager';
import { AppComponent } from './app.component';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule, FileManagerModule
  ],
  providers: [NavigationPaneService, ToolbarService, DetailsViewService],
  bootstrap: [AppComponent]
})
export class AppModule { }

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
<ejs-filemanager id='overview' [ajaxSettings]='ajaxSettings' [toolbarSettings]='toolbarSettings'
[navigationPaneSettings]='navigationPaneSettings'>
</ejs-filemanager>

Note: The appearance of the File Manager can be customized by using cssClass property. This adds a css class to the root of the File Manager which can be used to add new styles or override existing styles to the File Manager.

Switching initial view of the File Manager

The initial view of the File Manager can be changed to details or largeicons view with the help of view property. By default, the File Manager will be rendered in large icons view. When the File Manager is initially rendered, created will be triggered. This event can be utilized for performing operations once the File Manager has been successfully created.

Maintaining component state on page reload

The File Manager supports maintaining the component state on page reload. This can be achieved by enabling enablePersistence property which maintains the following,

  • Previous view of the File Manager - View
  • Previous path of the File Manager - Path
  • Previous selected items of the File Manager - SelectedItems

For every operation in File Manager, ajax request will be sent to the server which then processes the request and sends back the response. When the ajax request is success, success event will be triggered and failure event will be triggered if the request gets failed.

The current path of the File Manager can be specified initially or dynamically using the path property.

The following code snippet demonstrates specifying the current path in File Manager on rendering.

import { Component } from '@angular/core';

@Component({
    selector: 'app-root',
    styleUrls: ['app/app.component.css'],
    templateUrl: 'app/app.component.html'
})
export class AppComponent {
    public ajaxSettings: object;
    public path: string;
    public hostUrl: string = 'https://ej2-aspcore-service.azurewebsites.net/';
    public ngOnInit(): void {
        this.ajaxSettings = {
            url: this.hostUrl + 'api/FileManager/FileOperations',
            getImageUrl: this.hostUrl + 'api/FileManager/GetImage',
            uploadUrl: this.hostUrl + 'api/FileManager/Upload',
            downloadUrl: this.hostUrl + 'api/FileManager/Download'
        };
        // Specify the required current path
        this.path = '/Food';
    };
}
