Definitions

CRUD is a concept that encompasses the four stages essential to managing a database or persistent data storage – Create, Read, Update, and Delete. ReactJS is a JavaScript library used for building user interfaces. A CRUD web application is an application based on these four operations and built using ReactJS as its framework.

At its core, a CRUD web application enables a user to create, read, update, and delete any data that is stored in a persistent data storage. To create an application in ReactJS, developers utilize components, states, and props. Components are small, isolated blocks of code that enable the user to build custom, complex UIs. States are internal variables that help to manage data within the application, such as user inputs and interactions. And props is a type of data that is passed into a component to enable functionality.

To build a basic CRUD web application in ReactJS, developers must first define any data that will be stored and manipulated in the application. This data is usually stored in a database, such as MongoDB or MySQL. Next, the developer must create the components necessary for displaying data, taking user inputs, and other purposes needed within the application. With the components in place, the developer can implement logic and interactions that will invoke any of the CRUD operations. Finally, the ReactJS application is tested and deployed.

What is CRUD and Why Build a CRUD Web Application in ReactJS

What is CRUD?

CRUD is an acronym for Create, Read, Update, and Delete. CRUD operations are some of the most common and fundamental operations for manipulating data in any relational database. CRUD operations provide a consistent and predictable way to interact with a database in order to store, manipulate, and retrieve data.
CRUD operations allow for creating, reading, updating, and deleting data from a database. Create operations allow users to create a new item in the database, such as a new customer or product. Read operations allow users to retrieve a single item from the database or a set of items from the database. Update operations allow users to modify an item in the database, such as updating the price of a product. Finally, Delete operations allow users to delete an item from the database, such as a customer who is no longer active.

Why Build a CRUD Web Application in ReactJS?

CRUD web applications are a common type of application found on the web today. Building a CRUD web application in ReactJS is a popular way to quickly prototype and build a functional web application with the help of popular JavaScript libraries and frameworks. ReactJS is a popular choice for building a web application as it is now supported by major browser vendors and provides an excellent set of tools to build and maintain a web application.
ReactJS provides a library of components and tools to quickly prototype and build powerful web applications. Coupled with a modern back-end web framework, such as ExpressJS, ReactJS provides a powerful platform for building a CRUD web application. Furthermore, ReactJS is a JavaScript library which allows developers to quickly iterate and test their application without the need for a full-blown web framework.
In addition to the ease and speed of development, ReactJS supports several key features that make it an excellent choice for building a CRUD web application. These features include:

  • Virtual DOM – ReactJS utilizes a virtual DOM to quickly and efficiently render view components. This allows ReactJS applications to quickly respond to user events and render the components without the need to reload the page.
  • Components – ReactJS provides a powerful component-oriented architecture which allows developers to easily customize and build web applications.
  • State Management – ReactJS provides a powerful and robust state management system which helps developers to maintain data and application state.
  • Security – ReactJS provides several security features such as Cross-Site Request Forgery protection and Encrypted Value Retrieval, to ensure that the application is secure.
  • Performance – ReactJS applications are capable of providing some of the best performance on web applications and can scale easily.

Setting Up the Project Structure for ReactJS App

Project Setup

The first step in building a web application in ReactJS is setting up the project structure. This includes creating the React-specific files and folders, setting up the development environment, and constructing a basic HTML page to host our react components. First, create a new project folder and add an index.html page. This page will be the entry point for the React application. Next, install create-react-app, a CLI tool that will assist in setting up the React environment. Once complete, start up the development server and begin adding files and folders. Generally, the project folder will need a src and public folder. In the src folder, create a components folder to house individual React components. This components folder should also include an index.js file to help with importing and exporting components. Additionally, all css should be included in a folder inside the src folder. Lastly, create an App.js file in the src folder to handle the overall logic and arrangement of components.

Creating the Database

The next step in building a ReactJS application is designing the database that will store our data. This should be a relational database such as MySQL or PostgreSQL. Start by designing the tables that will hold our data. Fields should be carefully considered and should match up with the properties of our React components. Alternatively, a NoSQL database such as MongoDB could be used, but the structure of this data is less well-defined and additional considerations will need to be made in terms of storing the data in this type of database. Once a design for the database has been determined, the data should be transferred to a secure server. This will hold the current state of the application’s data and allow us to manipulate it via CRUD operations.

Creating the React Components

The final step in building a ReactJS web application is the creation of React components. These components will be responsible for fetching and manipulating data, as well as rendering it to the page. Start by constructing the components for the basic CRUD operations. Functions such as create, read, update, and delete should be handled in separate components. Additionally, any additional functionality such as authentication should be done in a separate component. After creating the components, they should be imported into the App.js file and put into an arrangement that makes sense. This will be dependent on the type of application being created, but generally, a sidebar for navigation and a main component that renders the current page should be included. Once complete, the React application will be ready to test.

Creating Components and Connecting Them to Create a CRUD Web App

The modern internet is highly interactive. To make the web more engaging, developers need to create web applications with features to create, read, update, and delete data. A web application capable of performing such tasks is referred to as a CRUD web application.

Understanding the Basics of CRUD

CRUD stands for create, read, update, and delete. As the acronym implies, these operations are essential for web applications that allow users to interact with data and create productivity applications. To code a full-fledged CRUD web application, the first step is to create individual components. Components in React are built using modular and reusable code units called components. Each component can also be broken down further into sub-components. These components need to be connected in a well-structured manner to form a CRUD web application.

Creating the React Components

The first step when building a CRUD web application in React is to create separate components for different sections of the application. The different sections include things like forms, list views, error messages, login screens, data tables, and more. All these components will need to be coded correctly so that they interact with each other correctly. These components must also be designed in such a way that they are independent of each other and do not share any dependencies. This helps in ensuring that individual components can be reused in other applications as well.
After the components have been created, they need to be connected in a structured manner. React components can be connected with one another using the React Router library. This library allows developers to link components up in a hierarchical manner. Using this library, developers can create single page applications without having to switch from page to page. It also makes it easier to keep track of the different components in the application.
Once the components have been connected, the last step is to setup the necessary services that will help in connecting the application to other backend systems. These services can include a database to store data from the different components and an API for communication between the application and the backend systems. With these components connected and the necessary services setup, the CRUD application will be ready for use.
