Vuejs post file download

Next, we add a removeFile key method which will remove the file from the file array. When the file is removed, the reactive nature of VueJS will update our listing. This method will remove the file from our uploaded files array. The method accepts the key in the files array of the file we are removing.

The full implementation of this method will be:. What this does is splice the files array at the index of the file we are removing and remove 1 entry from the array. When we do this, our list will re-render through VueJS keeping everything in sync. Since we are using a local files array, we can modify this at will. The next and final thing we have to do is submit our files to the server that the user has selected! This iterates over the files that the user has selected and prepares to submit them to the server.

This sends all of our form data to the server with the files that the user has uploaded! Like before, on the server side, you can access the files through the key of files which is the first parameter of the formData. When using Laravel and the Request facade, you can access the selected files the user has uploaded with the following method: Request::file 'files'. You can now do any processing you want!

There ya go! We made another component that allows the user to edit their file uploads before submitting to the server. Check it out and let us know your thoughts!

You can always include more information than just files with your post. When you build your FormData you can add additional text or other fields like this:. Now since we are configuring our request before we send it to the sever, arrays get accessed differently.

You will either need to account for this when building your FormData object. You can either iterate over your cool data and push it on a nicely organized array or you can do a JSON. You will just need to decode it before you can access it. When axios returns success, another quick tip is to reset your local files array back to nothing. You can simply clear your local files like this:.

Hopefully this tutorial has helped a little. There is always room for expansion and you can do progress uploads and other cool features. We are working on a book that will tie in this feature along with a whole bunch more API Driven ideals.

This is very similar to the Axios request where we pass formData as the second parameter to the axios. There are a few gotchas with doing file uploads.

First, as I mentioned in the intro, you can use PUT to send files to the server as well. With Axios, you can easily build in a progress indicator to show progress on uploading large files. As of this writing, you can not do this with the Fetch API. Next up, we will try to abstract some of the settings to a standard location to clean up the Fetch API requests and make them easier to use.

When the above link is clicked, the file is opened in a new browser tab, i need to prevent this default behavior and force a download upon click. The HTML 5 tag "download" is suppose to solve this problem doesn't seem to work. Chrome has recently deprecated the download tag form working with cross domain downloads.

Does vue have a modifier to prevent this default? Are there any other ways to download the file either in javascript or in html? One proposed solution is to read the URL as a arrayBuffer and then create a new blob in the DOM, and then create an anchor element and click it.. But that seems hacky to force a download of a file. I am sure their must be a cleaner solution to download a file form a URL, its a trivial problem, hoping for a simple solution.

You can fetch the file as a blob and provide it the same way, there will be no request that leads into CORS issues. Notes: I used Axios for my example but that's not a requirement, the blob's mime type is hardwired for the sake of simplicity.

If you want the browser to handle the download instead of handling the download in JavaScript you need to use window. This gives a better user experience IMO but gets tricky to set up when trying to access authorization-protected content.

To do this you need to store the authorization in cookies instead of relying on storing the authorization header in the browser's local storage. I'm using Laravel and Vue. How are we doing? Please help us improve Stack Overflow.
