In this guide, Handling of Complex States refers to the managing the state of one or more User Interface controls such as text fields, OK buttons, radio buttons, etc. in a graphical user interface. In this user interface programming technique, the state of one user interface control depends on the state of other user interface controls.
Moreover, Creating a Scrollable Table in React, with a huge amount of data you can use scroll functionality, as an alternative for the pagination. Scrolling functionality works vertically (y-axis) and horizontally (x-axis).
Data Visualization in React.js, web applications often have to help the end user make sense of different kinds of data. One of the best ways to show data in a nice and easy to understand way is to visualize it using graphs (charts). This article will demonstrate an efficient approach to creating React graphs by using the KnedoReact charts library, and we will implement Donut, Bar, Line and Sparkline graphs. We’re going with the React graph library that is part of KendoReact, as it is feature-rich and highly customizable. As part of a complete React UI components library, where this data visualization library really shines is its integration with the 90+ components within KendoReact, enabling developers to implement consistent styling and sleek design across an entire project.
Testing React Components, there are a few ways to test React components. Broadly, they divide into two categories:
- Rendering component trees in a simplified test environment and asserting on their output.
- Running a complete app in a realistic browser environment (also known as “end-to-end” tests).
This documentation section focuses on testing strategies for the first case. While full end-to-end tests can be very useful to prevent regressions to important workflows, such tests are not concerned with React components in particular, and are out of the scope of this section.
Building a Sliding Menu, in user interfaces today, sliding menus are all the rage. These menus are basically off-screen elements that slide into view when you click or tap on something that looks like an arrow, a hamburger icon, or something else that indicates a menu will appear.
Creating a Dropdown, before starts creating a dropdown list, it is important to know what is a dropdown list. A dropdown list is a toggleable menu that allows the user to choose one option from multiple ones. The options in this list are defined in coding, which is associated with a function. When you click or choose this option, that function triggers and starts performing. You have seen a dropdown list most of the time on registration forms to select the state or city from the dropdown menu. A dropdown list allows us to choose only one from the list of items. See the below screenshot how the dropdown list looks like-
React JS and Flux Architecture, flux is an architecture that Facebook uses internally when working with React. It is not a framework or a library. It is simply a new kind of architecture that complements React and the concept of Unidirectional Data Flow. That said, Facebook does provide a repo that includes a Dispatcher library. The dispatcher is a sort of global pub/sub handler that broadcasts payloads to registered callbacks. A typical Flux architecture will leverage this Dispatcher library, along with NodeJS’s EventEmitter module in order to set up an event system that helps manage an applications state.
