Cloudinary is a cloud-based service where you can store, manipulate, manage and serve images. I chose to use Cloudinary because it has a free tier that includes all the features I need. Cloudinary has the concept of transformationswhich are chained together to modify images however you need.

Once uploaded, the transformations occur, modifying and storing the new image. This is necessary so you can upload right to Cloudinary without negotiating a private key using a server-side language. This is where you can crop, resize, change quality, rotate, filter, etc. You now have a place to upload, manipulate, store, and serve images for your app. To handle the image upload, I used react-dropzone.

Call handleImageUploadpassing the image files[0] to this method. I broke this into a separate method, following the Single responsibility principle.

Essentially, this principle teaches you to keep methods compact and only do one thing. Using the. These pieces of data contain all the information Cloudinary needs to handle the uploaded image. By calling. Inside of the. Next, we check if the response we received contains a URL that is not an empty string.

I am assuming you already have some experience with CRA. If not, here is a great tutorial. The application has 3 possible states we need to account for:. We are going to set up each of those states in their own presentation component. First things first, Spinner. Not a lot to this one, it shows while the images are uploading.

A little more interesting here, we are passing in the images as a prop and then mapping over those images to produce the required jsx. But this is still pretty bland. Lets take a peek at our final presentation component, Buttons. If there was an additional button, I probably would have.

Here we are setting up our two buttons to either upload a single image file or multiple images. Still no big surprises.

Its time to move on to the meat of this project in the App. This is were the client starts to come alive. We have a couple of methods on the App class to help us manage the image upload workflow, onChange and removeImage.

This the core of the project so lets break it down a little bit. We are extracting the files to be uploaded out of the DOM and shipping them off to our server in a fetch request.

Time to get into the server code. And that is it!Last week I showed you how to upload images, resize and crop them using PHP. As I promised, this week I will show some modern and advanced HTML5 image upload techniques that you can use on your site.

HTML5 is a big trend and an awesome way of building sexy web applications that your users will just love. HTML5 introduced its File API for representing file objects in web applications, as well as programmaticaly selecting them and accessing their data.

Lets get our hands dirty and begin some coding. For HTML part, we will reuse the form from the last week and add some features to it:. We are not dealing with fancy styles, so there is no CSS involved. Notice the name of the file input.

It allows us to store multiple files as multidimensional array. The real thing here is that the browsers that do not support HTML5 features of FileAPI, will simply ignore multiple attribute and everything will act like in the first tutorial.

Try this now, select multiple files and you should see some file info below your form inside output element. This is ideal solution, when browser supports everything. Let me show you how to check for support in your browser:. If you run this code in Internet Explorer, you will be able to select only one file and alert will pop up that the File APIs are not supported. This really the interesting part. The JavaScript is veyr similar to before:.

There is plenty more stuff you can do with this. I will show you how to show the preview of the image before actual upload happen. This is a very neat feature. For example, your user wants to upload a photo directly from the camera.

The idea is to resize the image to some normal resolution before uploading and save time uploading it to server. This can be achieved with canvas and some of the techniques described above.
