Create a file called package. With the package. We're also going to need to configure Babel with a. The package. For right now, we want to get start working so we can load the application. The start script is currently configured to look inside of a folder called src so create a folder called src in the project directory and add the following files:. The index. It also loads the script build.

Our main. First thing's first, and we want to get some images displayed as quickly as possible! We will create a Gallery component that will display our images. In the project folder, create a file called Gallery. We've hard coded an array of data into this component, which is a great way to start working quickly. The Gallery extends Componentand in its constructor we set the initial state of the component. Finally, we render a basic structure with some styled markup. The image-scroller element uses the images array to produce multiple elements using map.

With the Gallery created, we can update main. For now, we are using the hard-coded image URLs via the flickrImages arrayand displaying the first image url as the selectedImage. We're accessing these properties by setting a default initial state within the Gallery component class constructor.

We can add interactivity to the gallery with an event handler that calls the setState method on the Gallery component:.A good solution of ReactJS carousel image gallery. This component brings many useful features, such as thumbnails, slider, swipe and more, as we mobile support!

Image Carousel

Nothing can help you learn like trial and error. When you get your hands dirty your brain is like sponge. Your ability to absorb new knowledge is incredible.

In addition, learning by practice is also more fun. For this reason, I decided to write this short tutorial on React. I hope it will help you learn React and improve your skills. Live demo on CodePen. Source code on GitHub.

How TO - Responsive Image Grid

In a fact, the last tutorial appeared on this blog on September Also, it is a coincidence that the last tutorial was about React. In this tutorial, we will create stunning image gallery. In addition, this gallery will also contain modal dialog for previewing bigger version of images. This gallery will require a number of resources. Enjoy this tutorial.

The first thing we have to do to build the gallery and learn React is to gather necessary resources. In this tutorial we are are going to use three CSS stylesheets.

The goal of normalize stylesheet is to stick to CSS best practices. In short, different browsers render various elements in a different way. We want to reduce these browser inconsistencies. As a result, we will create consistent cross-browser experience. Stylesheet from Bootstrap framework will provide this tutorial with grid system. We will use it to distribute the images in our gallery. Although, we could write some simple grid system.

However, that would cost us some time we can use more wisely. What is the reason for implementing the last stylesheet Font awesome? Well, I want to use two icons in this tutorial. We will use the first icon as a label for opening the modal window. This is all for CSS. What about JavaScript?

We will need two libraries to make this tutorial on how to learn React by practice work. We will not use jQuery or any other library.

One thing about JavaScript. Therefore, it is high likely that you will need some compiler to convert the code into older syntax of JavaScript. Otherwise, it will probably not work in older browser.

In this tutorial, I used babel.React Bootstrap images are automatically adjusted to all screen sizes - image will never be larger than parent elements. Its styles can be changed via classes.

In addition to our border-radius utilitiesyou can use. Align images with the helper float classes or text alignment classes. Take a look at our masks section to know all the colors possibilities.

Strong overlay. Light overlay.Too long? Skip the text and jump straight to the code. React is a declarative Javascript library that allows you to create reusable UI components that can handle events and data changes.

This is done by using a transformer like Babel more on this later. For now, let's create a PhotoGallery. The Photo component will represent a single photo view in our gallery. A component usually starts with an upper case letter and is defined using the React. For now, the only function the component will have is a render function that returns the html for displaying an image.

In order to reuse this component for multiple photos, we need to pass in the image URL instead of hard-coding it inside the img tag. React components receive information via the props object, so we can add a photoURL property to it and pass in a different URL for each photo.

Note that since photoURL is a Javascript expression we must place it in curly braces to evaluate it when assigning it to the src attribute.

Let's update Photo to use a div with a styled background image instead of a plain img tag. This will help us add some fancy functionality later. We want the background image of our div to point to the photo URL. However we are getting it dynamically from the props object so we can't reference it inside a static CSS file.

The convention for dynamic CSS properties is to store them in a separate object and assign it to the style attribute. The static CSS properties can go into a separate CSS file as usual, with the corresponding class name assigned to the className property. Now that we have a Photo component, let's build a Photo Gallery component that will display multiple photos in a row.

Just like before, the PhotoGallery component has a render method that returns the HTML necessary to display its contents. We loop over these URLs in the render method to create an array of Photo components. These will then be included as children of the div in the return statement.

Now that we have a gallery, let's create an HTML file that will render it in the browser. The head contains a link to our CSS file:.At its core, React is just a UI toolkit, ala GWT, but it has a very healthy ecosystem around it that provides everything you need to build a kick-ass progressive web app PWA.

It uses webpack under-the-covers to build the project, launch a web server, and run its tests. Spring Boot has a similar tool, called Spring Initializr. Both tools are worth looking into, and you can learn how to create a basic app with them by reading my Bootiful Development with Spring Boot and React tutorial.

JHipster is an application generator that initially only supported Angular and Spring Boot. In its version 5. JHipster v5. You can use npm, but JHipster will use Yarn if you have it installed. If you have Git installed, JHipster will auto-commit your project after creating it and will allow you to upgrade between versions. To create a photo gallery app with JHipster, create a directory, and run jhipster in it.

When you choose OAuth 2. This means you need to have an identity provider IdP that stores your users and allows your app to retrieve information about them. A default set of users and groups is imported at startup, and it has a client registered for your JHipster app.

Then run the following command in a terminal window:. This screen allows you to enable forgot password, remember me, and verify by email as well.

Navigate to Roles and click on the Default Roles tab.

Click Users and Add. One of the features I added to JHipster is what I like to call save user snapshot. This feature allows you to create relationships with the User entity. The only downside is when you have entities with a user relationship, the users dropdown will only contain the users that have logged into your app.

When using Spring Security with Spring Boot, you can configure most configuration settings in a properties files. You can even override properties with environment variables.

You can try this example live in Archriss' showcase app on Android and iOS or check out the demo. This component supports both remote images by specifying source. Be aware that the width and height must be defined for local images, but is not required for remote images! Although the dimensions could still be provided for remote images to save the gallery from fetching them, which could potentially improve performance.
