I have a web api set up which returns a pre-signed url with the relevant details. I am having a hard time getting this set up to work. The documentation says that the url should be supplied as a props to the file upload component like so. I am firing the web api call once the file passes the inputFilter filter criteria which in my case just checks for a text file extention.

I am able to get the correct signed url which even works when I put the url as the value for the put-action props like so. However, when trying to set it dynamically, the start upload status says - No action configured which is odd as I am sure the variable is being set after the promise is returned from the API. I have tried to set the props after the promise is returned as suggested here and even tried to re render the upload component after promise is returned as suggested here but still I am getting the same message.

Managed to get this working by setting the file level property putAction like below.

Otherwise you are hogging up your server bandwidth and cpu time.

For cross-checking, here is the official documentation on browser-based uploads. Obviously, you need to create a bucket to hold your files, at the S3 management console. Also, you should create a minimal-privilege user instead of using your own credentials. You do that at the Amazon IAM management console. After you create a user and save its key pair, you must declare its permissions by adding an IAM policy.

The minimal policy that is required to upload files to S3 is:. Note that this is different from the upload policy. This policy limits actions that are possible if you have both the access key and the secret key. Thus, if someone steals that key pair, the consequences would be few. So you must let the S3 bucket know that you are going to make uploads from your website domain. Otherwise any requests will be considered unsafe and rejected by the browser.

The request contains the file, a filename key, in S3 termssome metadata, and and a signed policy more about that later. The structure you see in GUI clients is just a convenience. Internally, every file uploaded to S3 is referenced by a flat string key. The policy is like a ticket that permits the client to upload something to your S3 bucket.

The secret key must be concealedwhich is why the policy has to be constructed and signed on the server. In the simplest of scenarios, I guess, you can pre-sign a single policy for all future uploads, and get around having a server part to your app. But, typically, it is important to only allow a safe subset of keys to be uploaded, ideally a specific key, because this is the only access control you get with uploading files - without a proper restriction, a client can replace any file in the bucket with his upload.

Another thing is controlling file size and ensuring the file has proper access level - typically public-read.

The policy has an expiration time, after which it becomes invalid. The best practice is to construct the policy on-demand just before the upload and set the policy lifetime to a minimum, like a couple of minutes. This minimizes the risk of someone reusing the policy. I found it most convenient to have the backend prepare the entire set of parameters, rather than having the policy logic on the backend and the parameter logic on the frontend.

The most complicated part of all this is generating the signature. Take note that the intermediate hashing steps use binary keys, and only the final result is hex-encoded. The only important detail is that the file field must be the last in the form data. I bet you would like to use it for this upload, too - and it is indeed the easiest way to set up a user-friendly upload form.

To demostrate all of this, I made a minimal working uploader with source on Github. Liked the post?GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

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.

How to Handle File Uploads in Vue 2

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.

Now we can begin to make our axios request! We will be doing this through the post method. The third parameter is a config for the request which is awesome because we can add other headers to it.In this article, we will talk about how to handle file uploads with VueJs. We will create an images uploader that allow user to upload single or multiple images file by drag and drop or select file dialog. We will then upload the selected images and display them accordingly.

We will also learn to filter the upload file type, for example, we only allow images, do not allow file type like PDF.

We will be using VueJs to handle the UI part. We need a backend application to accept the uploaded files.

You may follow the backend tutorials or download and run either one of these server side application to handle file upload for your backend We will be using File upload with Hapi. We will also learn the tricks to enable fake upload on the front-end.

Upload file to S3 with Laravel and Vue.js

We will be using vue-cli to scaffold Vue. We will be using the webpack-simple project template. Let's proceed to create our service. We will be using axios to make HTTP calls. Nothing much, the code is pretty expressive itself. We upload the files, wait for the result, map it accordingly.

You may run the application now with npm run dev command. Try uploading a couple of images, and it's working! Remember to start your backend server. We can upload the files successfully now. However, there's no indication in UI. Let's update our HTML template. If you are lazy to start the back-end application Hapi, Express, etc to handle file upload. Here is a fake service to replace the file upload service. Came across this solution in this Stackoverflow post.

Pretty useful. My online demo is using this service.

Before you can upload files and folders to an Amazon S3 bucket, you need write permissions for the bucket. When you upload a file to Amazon S3, it is stored as an S3 object.

Objects consist of the file data and metadata that describes the object. You can have an unlimited number of objects in a bucket. You can upload any file type—images, backups, data, movies, etc. The maximum size of a file that you can upload by using the Amazon S3 console is GB. You can upload files by dragging and dropping or by pointing and clicking. To upload folders, you must drag and drop them. Drag and drop functionality is supported only for the Chrome and Firefox browsers.

When you upload a folder, Amazon S3 uploads all of the files and subfolders from the specified folder to your bucket. It then assigns an object key name that is a combination of the uploaded file name and the folder name.

The key names include the folder name as a prefix. If you upload individual files and you have a folder open in the Amazon S3 console, when Amazon S3 uploads the files, it includes the name of the open folder as the prefix of the key names. For example, if you have a folder named backup open in the Amazon S3 console and you upload a file named sample1. However, the object is displayed in the console as sample1. If you upload individual files and you do not have a folder open in the Amazon S3 console, when Amazon S3 uploads the files, it assigns only the file name as the key name.

For example, if you upload a file named sample1. If you upload an object with a key name that already exists in a versioning-enabled bucket, Amazon S3 creates another version of the object instead of replacing the existing object.

If you are using the Chrome or Firefox browsers, you can choose the folders and files to upload, and then drag and drop them into the destination bucket. Dragging and dropping is the only way that you can upload folders. In the Bucket name list, choose the name of the bucket that you want to upload your folders or files to. In a window other than the console window, select the files and folders that you want to upload. Then drag and drop your selections into the console window that lists the objects in the destination bucket.

Drag and drop more files and folders to the console window that displays the Upload dialog box. To add more files, you can also choose Add more files. This option works only for files, not folders. To immediately upload the listed files and folders without granting or removing permissions for specific users or setting public permissions for all of the files that you're uploading, choose Upload. To set permissions or properties for the files that you are uploading, choose Next.

Choose Add account to grant access to another AWS account. Under Manage public permissions you can grant read access to your objects to the general public everyone in the worldfor all of the files that you're uploading. Granting public read access is applicable to a small subset of use cases such as when buckets are used for websites. We recommend that you do not change the default setting of Do not grant public read access to this object s.

You can always make changes to object permissions after you upload the object. On the Set Properties page, choose the storage class and encryption method to use for the files that you are uploading.

You can also add or modify metadata. Choose a storage class for the files you're uploading.
