File Upload Progress Indicator with Axios and VueJS

Thank you good sir!! This helped me tremendously in serving non-PDF files in a react web app I'm working on.

Download for IE works with FileSaver. Thank you very much! I'm using Tomassito 's code as I think it's cleaner. Really nice snippet! Thanks for sharing! Thank you to javilobo8 and Tomassitowhose version I am using. Great share! Thanks a lot! To set type of file and filename from "content-disposition" -header you can use this:.

I was looking for such a solution, and it works amazing. For me this is not working properly when using blob response type. It only works when i set responseType to arraybuffer. Also when using arraybufferit shows downloading after 1 minute or so depending on file size. Help, this way the pdf is first streamed, then recreated, but without all the images. Can I somehow directly download the created pdf on the server side, it's all intact, pictures there and everything?

Or how can I get around this? Sorry for the probably dumb question, I'm new to js altogether. OK ; result. Length; return result. React: this. This saved my self-confidence after 10 days struggling with the problem and trying every possible combinations of solutions!

Quality snippet right here! The link from RickMeijer helped out tooOn the back end you can use the framework that you want, or language that you want.

The biggest take aways will be how to do the uploading of the file with VueJS and Axios. This is what makes the process a whole heck of a lot easier. So first, we will start with a single file to get things going. I just built a simple component that contains a file input:.

The first is a ref attribute that gives this input a name.

We can now access this input from within VueJS which we will in a second. When the user uploads a file, this gets called and we can handle the file. We will be implementing this method in the next step. The last element in the simple form is a button that calls a method submitFile when clicked. This is where we will submit our file to the server and we will be implementing this method as well. The first thing we want to do is add the handleFileUpload method to our methods object which will give us a starting point for implementation:.

What we will do in this method is set a local variable to the value of the file uploaded. The FileList is not directly editable by the user for security reasons.

However, we can allow users to select and de-select files as needed, which we will go through later in the tutorial. In our data method add:. Now we have something to set in our handleFileUpload method! The this. This makes it easily accessible within our component. Next, what we will do is append the file to the formData. This is done through the append method on the object: FormData.

What we are doing is essentially building a key-value pair to submit to the server like a standard POST request:. We just append the file variable that we have our data stored in.In this tutorial, you'll learn how to handle multi-part Form Data in React by implementing a simple file upload example.

After creating the files and installing the dependencies, you can start your React app using the following commands:. This will also automatically open your web browser and navigate to that address.

Let's now create a component that contains a form for file uploading. We import React and axios and we create and export the FileUploadForm component. Next, we need to define the onSubmit and onChange methods in the component as follows:.

The onChange method calls the setState method to set the file state variable to the selected file. The file is passed as a parameter to the method from the file state variable. Next, we call the post method of axios and we pass the formData instance as the data object. Sponsored Links. How to detect route changes with React Router 5 Hooks? What's new with React Router 6?

This get's around max upload sizes allowing you to upload large files. If prop multiple is true a file list is rendered on selecting files otherwise file upload will begin on selection. Drag is supported and when files are dragged over the uploader the class vuejs-uploader--dragged is added to the root element.

For resumable uploads we need to know what parts have already been uploaded so we don't bother re uploading them. This component makes use of a response property that returns an array of parts remaining that still need to be uploaded. If this property is in the response it will remove any parts in the queue that are not in that array. To make use of this property it expects to be formatted as meta. Skip to content.

Almost any modern web application allows you to do this. Up until this point, we have all the different tricks to upload files with VueJS and Axios. In this tutorial we are going to combine all of these tricks to make the ultimate file uploader with VueJS and Axios.

The user will be able to select which files they want through dragging and dropping or selecting through the standard uploader.

This tutorial will flow in steps, we will: 1. Build our drag and drop base. Add previews for the files selected if they are images 3. Upload the selected files 5. Add a progress bar 6. Take a short derivative for the direct to upload process. This will upload the files when they are dropped onto the drop base.

Lots of cool stuff in this tutorial, but it can get a little complicated at times so reach out if you need a hand during any of the steps! This is the guts of the tutorial, but also where we should start. The key to having a drag and drop file uploader is to have an element where you can drag and drop files.

First, we need to create an empty Vue Component. In this component add the following component stub:. In here is where we will build all of our functionality.

I added a real basic style for the form which just centers it in the screen and added some text to instruct the users where to drag and drop the files. This allows us to access the element from within our component code. The first piece of functionality we will add to our component is a check to see if the drag and drop functionality is supported or not. This flag will determine if we show the text to allow drag and drop and if we even bind the events to the elements. We also added an array of files that will store the files the user selected when they dragged and dropped over the element.

Next, we will want to add a method that determines whether the browser is drag and drop capable. Add the following method to your methods object in the Vue component:.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Sign in to your account. I've spent a few hours today trying to get a post request to work with a few parameters and a file that I need to upload.

What am I doing wrong? The code looks good to me. You don't need to set the Content-Type, but it's not important. What happens when you try to send a request via axios? I noticed that setting Content-Type or not doesn't change anything on this case. When I try to send the request with Axios, seems like data goes as an empty string so the backend will respond with an error related to missing parameters.

Please let me know if there's anything else I can do to help debug this, ok? Tks nickuraltsev! Could you please take a look at how your requests look like in Chrome Dev Tools Network panel and provide a screenshot if possible?
