We can request any sort of data from an API and then use this approach to save data inside our computer.Īll the major browsers support all the above methods except the method using the Axios library. This method is not restricted to the plain text entered by the user like the previous method.

Here we get random images from a site, use Axios to request those images in the form of blobs, and then download them using the anchor tag’s download attribute. createObjectURL(new Blob()) Ĭonst link = document.createElement('a')

Attach this link to the document and simulate a click using the.

Set href as the URL created in the first step and download attribute as the downloaded file’s name.Create a DOMString that contains the URL representing the Blob object.Resolve the promise returned by the Axios request by performing the following steps:.Create an Axios get request with URL as the source of the file and the responseType as a blob.

It represents data like programs, code snippets, multimedia objects, and other things that don’t support JavaScript native format. Blobīlob stands for Binary Large Object and is a data type that can store binary data. Before proceeding with the approach’s details, let us understand what Blob is, the data type used to download files using Axios. In this approach, we will use the Axios library to download files. Var text = document.getElementById('text').value

Var element = document.createElement('a') ĮtAttribute('href','data:text/plain charset=utf-8, ' + encodeURIComponent(textInput)) ĮtAttribute('download', filename) Call the download function with text from the text area and the text file’s filename as parameters.

Remove the element from the body of the document(HTML page).Īttach an event listener looking for a click to a download button.

Use element.click() to simulate a mouse click.

Append this created element to the body of the document(HTML page).

Set the date type to text/plain and encoding to UTF-8 using the data:text/plain charset = utf-8 as the attribute value of href.

This will help us to replace certain special characters with a combination of escape sequences.

Use the encodeURIComponent to encode the text and append it to URI as its component.

Create an anchor tag using the createElement property and assign download and href attributes to it.

Create a text area to enter the text data.

I'm not sure of the diffence between the left column choices, so I'd set them both.Įdge seems to be the easiest of all. In essence the Fetch API fetch () method returns a response, from which a blob can be. For the XHR request we use the Fetch API with the whatwg-fetch polyfill. Choose your desired outcome for that item in the right column. To solve this it was necessary to download the file to memory with an XHR request and then get the browser to open or download it with whatever plugin/UI it normally uses for pdf file. Find PDF as the content type and chose betweem (application/download) and (application/pdf) in the left column. Go to General settings and scroll a little more than halfway down the page to Applications. That's cleverly hidden setting deep in the bowels of Chrome will solve your problem in that browser.įirefox makes this easier. Click on that, then select Download PDF files instead of automatically opening them in Chrome. Scroll way down the page to Additional content settings where you'll find PDF documents as the fourth entry. Find Permissions and click on Additional permissions at the bottom of that section. To set Chrome to download pdf files rather than opening them in the Chrome viewer, open Settings, click on Privacy and security, then Site Settings. I never use Chrome, but I just opened it and checked settings.
