To create a download link for a file in HTML, you can use the <a> (anchor) element with the download attribute.
`
<h1>Download File Example</h1>
<p>Click the link below to download a sample file:</p>
<a href="path/to/your/file.txt" download="filename.txt">Download File</a>
`
The download attribute specifies the default filename that the file should have when downloaded. In the example, it's set to "filename.txt". You can change this to whatever name you prefer.
In addition to adding data from the backend, you can also include this. I'm using Laravel in this case.
Simulate fetching data from the backend (replace this with your actual data retrieval logic)
const dataBackend = "Your Data From Backend : " + {!! json_encode($dataFromBackend) !!}
Create a Blob containing the data
const file = new Blob([dataBackend], {
type: 'text/plain'
});
Create a download URL for the Blob
const url = URL.createObjectURL(file);
Set the download link's href attribute to the URL
document.getElementById('downloadLink').href = url;
A Blob (Binary Large Object) is a data type used to represent binary data in the form of a file-like object. Blobs can store various types of data, such as text, images, audio, and more. They are particularly useful in web development, especially when working with files and handling binary data. Blob has two parameters :
const blob = new Blob(array, options);
- array : An array containing the data to be stored in the Blob. Each element in the array represents a chunk of binary data.
- options (optional): An object specifying the MIME type or content type of the Blob. For example, { type: 'text/plain' } indicates that the Blob contains plain text.
You can also visit the blob documentation link to find out what features are provided by the blob.
