WML File Upload

The wml-file-upload library is designed to enhance Angular applications by providing robust file upload capabilities. This library streamlines the process of integrating file upload functionality, addressing common challenges such as handling multiple file formats, validating file sizes, and providing feedback on the upload process. Its primary goal is to offer a configurable and efficient solution for developers to incorporate file upload features into their applications, with a focus on ease of use and flexibility.

At the heart of the wml-file-upload library are several key components that facilitate its core functionality. The library includes components for file selection, upload progress indication, and error handling. These components work in concert to provide a seamless user experience, allowing for the asynchronous upload of files with real-time progress feedback. Developers have the ability to customize these components, tailoring the file upload experience to their application's specific needs. Parameters and services are exposed to enable customization, such as defining file size limits, specifying allowed file types, and customizing the UI elements. The library also supports interactivity, offering hooks and events that developers can leverage to create dynamic responses to the file upload process. In terms of implementation, the library encourages a modular approach, where developers can integrate and configure the file upload components within their existing Angular applications, ensuring flexibility and adaptability to various use cases.

Installation

npm install -d @windmillcode/angular-wml-file-manager

Usage

wml-file-upload Component Usage

The wml-file-upload component from the @windmillcode/angular-wml-file-manager library provides a robust solution for implementing file upload functionality in Angular applications. This guide illustrates how to use the component for various developer needs.

Basic Usage

To start using wml-file-upload, first ensure that the WmlFileManagerModule is imported into your module:

import { WmlFileManagerModule } from '@windmillcode/angular-wml-file-manager';

@NgModule({
  declarations: [
    // other components
  ],
  imports: [
    // other modules
    WmlFileManagerModule,
  ],
})
export class YourModule {}

HTML

Create a simple file upload interface:

<wml-file-upload [params]="uploadParams"></wml-file-upload>

TypeScript

Configure the uploadParams in your component:

import { WMLFileUploadParams } from '@windmillcode/angular-wml-file-manager';

@Component({
  selector: 'your-component',
  templateUrl: './your-component.component.html',
})
export class YourComponent {
  uploadParams = new WMLFileUploadParams({
    dragDropText: 'Drag and drop files here or click to browse',
    browseFileText: 'Browse Files',
  });

  constructor() {}
}

Advanced Usage

Custom Validation

You can provide custom file validation logic by defining the uploadAllowedPredicate function:

TypeScript

uploadParams = new WMLFileUploadParams({
  dragDropText: 'Drag and drop files here or click to browse',
  browseFileText: 'Browse Files',
  uploadAllowedPredicate: (file: File, fileList: File[]) => {
    // Custom validation logic, for example, restrict file size and type
    return file.size <= 1048576 && ['image/jpeg', 'image/png'].includes(file.type);
  },
});

Handling File Upload

To handle file uploads, define an uploadFn function that returns an Observable to handle the upload process:

TypeScript

uploadParams = new WMLFileUploadParams({
  dragDropText: 'Drag and drop files here or click to browse',
  browseFileText: 'Browse Files',
  uploadFn: (fileItem: WMLFileUploadItem) => {
    // Return an Observable from the upload service
    return this.fileUploadService.upload(fileItem.file);
  },
});

TypeScript: File Upload Service

An example upload service method:

@Injectable({
  providedIn: 'root',
})
export class FileUploadService {
  constructor(private httpClient: HttpClient) {}

  upload(file: File): Observable<any> {
    const formData = new FormData();
    formData.append('file', file);

    return this.httpClient.post('/api/upload', formData);
  }
}

By following these examples, you can configure the wml-file-upload component for basic and advanced use cases, including custom validation and file upload handling.

Changelog

0.1.7

uploadAllowedPredicate - allows developer to edit the files list after the uploadAllowedPredicate validation for additional modfication or aux tasks as needed be sure to return WMLFileUploadItem[] | this.params.files as necessary

1.0.0

* ensured that there is support for ngx-translate and non ngx-translate features
* to enable translation

export function HttpLoaderFactory(http: HttpClient) {
  return new TranslateHttpLoader(http);
}
    HttpClientModule,
    WmlFileManagerModule
    .forChild(
      new WMLModuleForRootParams({
        ngxTranslateLoaderFactory:HttpLoaderFactory
      })
    ),

* to disable translation

    WmlFileManagerModule

1.0.1

• minor dependency update

2.0.0

• MAJOR rename to angular-wml-file-manager
  • fixed major problems concerning ngx-translate

// translate
// first make sure to have ONLY ONE in the imports for AppModule
