In today’s digital-first age, online site performance is critical for ensuring business continuity, attracting repeat sales, and gaining a competitive advantage. Lazy loading accelerates page loads of websites and apps. Many implementation techniques are available, however, so choose wisely. In particular, become familiar with the universal practices and the language- and framework-specific approaches.
React is a popular open-source JavaScript library for creating user interfaces (UIs) for single-page web applications, with React Native slated for building mobile apps. Helpfully, React organizes UIs into collections of reusable components, rendering feature management a cakewalk. However, to boost user engagement, conversion, and SEO ranking, you must optimize your app for fast page loads.
React Native is a popular open source software that enables you build mobile applications easily with JavaScript. Other similar and popular options out there include Ionic, Lungo, Sencha Touch and NativeScript Vue. You can use your existing knowledge of HTML5, CSS and JavaScript to develop mobile applications without having to learn a different set of skills.
In our first article, we built a part of the front-end of our image search tool with the focus mainly on the parent App.js stateful component.
In this article - part two of a series - we will continue developing a AI image Search App, in which users can search for content in an image, not just the description. The app is built with React for UI interaction, Cloudinary for image upload and management and Algolia for search.
What if we could create an AI image search service? Type in a word and get images with titles or descriptions matching our search. Better yet, what if we could create an AI image search service but rather than matching just titles and image description, we can search for something in an image, regardless of the given image title or description. For example, find one with a dog in it, or those that may have a street lamp or a bus (more like an image search tool).
In this talk, the audience learns everything they will ever need to know about playback controls, offline media, image & video optimization and transformation, pre-loading, deep learning with Images, audio & improving web performance by using the right tools while dealing with media assets in their react apps.
This is part 2 of a 3 part series
React has become more popular, as well as more mature, over the last four years since its release by Facebook. It has become one of the go-to technologies for people looking to componentize the front-end of any web application. It also helps that an entire mobile stack is built around React in the form of ReactNative. The components are wonderful, however there can be a burdensome learning curve. But, in the end, there’s the payoff of highly reusable code and a better user experience.
To start building a user interface, you might use React, a JavaScript library for building flexible and reusable components. However, you also need a supporting tool for managing digital media (images and videos). The recently announced React SDK from Cloudinary capably serves that purpose.
Developing a library requires a different approach from developing an application. You must consider the use of the library in someone else’s application and design for it. React is well suited for this purpose. And if the library you are creating is an adapter to another library, you can dynamically generate the component's properties definition to ensure they are forward compatible. There is however more than one way to achieve the same goal, with some conventions to follow and others to cautiously not follow. In particular, I chose to use the context function even though it is an experimental feature because it is useful when you don’t know, or can’t dictate, the way your library's components will be utilized.
