Data Visualization With ApexCharts

ApexCharts is a modern charting library that helps developers to create beautiful and interactive visualizations for web pages with a simple API, while React-ApexCharts is ApexChart’s React integration that allows us to use ApexCharts in our applications. This article will be beneficial to those who need to show complex graphical data to their customers. Getting Started First, install the React-ApexCharts component in your React application and import react-apexcharts. npm i react-apexcharts apexchartsimport ReactApexCharts from 'react-apexcharts' The core components of an ApexChart is its configuration object. In the configuration object, we define the series and options properties for a chart. series is the data we want to visualize on the chart. In the series, we define the data and n...

FLIP Animations in React

With a very recent Safari update, Web Animations API (WAAPI) is now supported without a flag in all modern browsers (except IE).  Here’s a handy Pen where you can check which features your browser supports. The WAAPI is a nice way to do animation (that needs to be done in JavaScript) because it’s native — meaning it requires no additional libraries to work. If you’re completely new to WAAPI, here’s a very good introduction by Dan Wilson.One of the most efficient approaches to animation is FLIP. FLIP requires a bit of JavaScript to do its thing.Let’s take a look at the intersection of using the WAAPI, FLIP, and integrating all that into React. But we’ll start without React first, then get to that. FLIP and WAAPI FLIP animations are made much easier by the WAAPI!Quick refresher on FLIP...

React Integration Testing: Greater Coverage, Fewer Tests

Integration tests are a natural fit for interactive websites, like ones you might build with React. They validate how a user interacts with your app without the overhead of end-to-end testing.This article follows an exercise that starts with a simple website, validates behavior with unit and integration tests, and demonstrates how integration testing delivers greater value from fewer lines of code. The content assumes a familiarity with React and testing in JavaScript. Experience with Jest and React Testing Library is helpful but not required.There are three types of tests:Unit tests verify one piece of code in isolation. They are easy to write, but can miss the big picture. End-to-end tests (E2E) use an automation framework — such as Cypress or Selenium — to interact with your s...

Using Formik to Handle Forms in React

There is no doubt that web forms play an integral role in our web site or applications. By default, they provide a useful set of elements and features — from legends and fieldsets to native validation and states — but they only get us so far when we start to consider the peculiarities of using them. For example, how can we manipulate the state of a form? How about different forms of validation? Even hooking a form up to post submissions is a daunting effort at times.Component-driven front-end libraries, like React, can ease the task of wiring web forms but can also get verbose and redundant. That’s why I want to introduce you to Formik, a small library that solves the three most annoying parts of writing forms in React:State manipulation Form validation (and error messages) Form ...
