Automated tests are especially important in large applications that have lots of moving parts. It is smart to learn about many methods of testing applications so that you can provide as much coverage as possible. If you are not familiar with using snapshots in testing, read on. Snapshot tests are written as part of frontend test automation.
React, a front-end framework for building user interfaces, uses component-based architecture and non-opinionated design principles, making it a developer favorite. React has been widely adopted and has a large community of developers behind it. Netlify is a popular framework for hosting React applications, but it does not provide your team with the highest level of control over the deployment process. As a result, you are not able to perform important tasks like running automated tests.
For most of my career I’ve worked with health and wellness startups. Most of these companies have a wearable that tracks movement, heart rate, body weight or stimulates a body part. The common denominator between these apps is their use of sensor data to determine physiological progress an athlete is making. Problem is, your Bluetooth Low Energy (BLE) device does not have an internet connection and cannot send diagnostics anywhere if there are errors.
Data visualization is the process of translating large data sets and metrics into charts, graphs, and other visuals. The resulting visual representation of data makes it easier to identify and share real-time trends, outliers, and new insights about the information represented in the data. Using CircleCI webhooks, we can gather data on workflow and job events. In this tutorial, I will lead you through the steps to create a React-based dashboard to visualize this data.
If a picture is worth a thousand words, then a well-done data visualization is worth a million. The quality of a dashboard can make or break an application. In this tutorial, you will learn how to make high-quality data visualizations easily by using the Nivo charting library with ReactJS. You will also learn how to query data stored in InfluxDB to make your charts dynamic and versatile.
Sometimes, managing several input fields gets crazy complex. You may need to recreate the same thing for each form and that’s can be really time-consuming. With a reusable Text Input in React, you can create just one input element in just one component and reuse it everywhere in any form. Let’s do this.
Since its release in 2013, React.js has become one of the most popular solutions for building dynamic, highly interactive web app frontends. React’s declarative nature and component-based architecture make it easier to build and maintain single-page applications.
React Native has come a long way since an internal prototype at Facebook to where it is now. The cross-platform framework is now a go-to tool for businesses to develop natively rendered mobile apps for iOS and Android. Thanks to its reduced development time with hot reloading to its focus on runtime performance with natively rendered views, React Native has gained traction with large-scale companies like Shopify and Tesla. Web developers have made the leap from the browser to mobile bringing with them all of their tools and expertise, and it is consistently the most popular cross-platform framework.
