Learn the process of seamlessly uploading various document formats, videos, and previewing documents with Angular software

I am having trouble viewing uploaded files in the carousel. While I can see video and image files, other document formats are not displaying. Can someone please recommend a solution to enable viewing all types of documents as well?

  mydata = []
  onSelectFile(event) {
    const files = event.target.files;
    if (files) {
      for (const file of files) {
        const reader = new FileReader();
        reader.onload = (e: any) => {
          if (file.type.indexOf("image") > -1) {
            this.mydata.push({
              url:e.target.result,
              type: 'img'
            });
          } else if (file.type.indexOf("video") > -1) {
            this.mydata.push({
              url:e.target.result,
              type: 'video'
            });
          }else if (file.type.indexOf("ppt") > -1) {
               this.mydata.push({
              url:e.target.result,
             type: 'ppt'
        });
      }

        };
        reader.readAsDataURL(file);
      }
    }
  }

Answer №1

Within the HTML template on stackblitz, there is a reference to an object element for displaying a PDF document. As per the documentation provided by Mozilla, it is necessary to indicate the type of document being used. In this scenario, for PDF documents, you should include:

<object *ngIf="list.type == 'pdf'" [data]="list.url" type="application/pdf"></object>

By specifying the type as "application/pdf", the PDF file will be properly rendered. For other types of documents, ensure to specify the appropriate type as detailed in the documentation.
