How to Add Script Tag to React/JSX?

When it comes to app development, using a third-party library is common. It is the best way to develop an app for the web. 

React is an extremely demanding framework in the app development market today and creates cross-platform applications easily. If you want to complete the project successfully, you can hire react developer from a reputable company and carry out the development process smoother. 

• Whether you want to add a third-party library, you must install and use the NPM package. 
• You can easily install packages and import them for use.
• In a certain scenario, the package is unavailable, and you need to embrace files from the external source or CDN directly.
• Adding a script tag in index.html may or may not work every time. 

You must look at why an error arises when adding a script tag in react components. You can understand the different array of the process to obtain javascript around react that make the app development process easier and faster.

Why it shows an error:

React utilizes react DOM to deliver JSX content on the web page. React DOM is virtual that exists on top of the original DOM. It renews changed nodes from the DOM. Original DOM updates after every change. 

React DOM employs createElement to change JSX into DOM elements. createElement function requires innerHTML API to add a changed node in the browser’s original DOM. HTML5 states that script tags never execute if they insert with innerHTML. It is the main reason that the execution of the script tag shows an error in react.

Implement the right solution:

The best solution is to add a script into DOM directly with the help of a document interface by web API. Developers utilize the javascript DOM manipulation method to add script tags without interfering with react DOM. 

You can understand what to do to add a script tag. In the script tag page, the user interface can categorize into diverse processes like logic and react components. 

• First, move to head and script tag from DOM.
• After that, you can utilize the setAttribute method to include a new script.
• Modified script tag can append to head.

When it comes to reacting, the script can add to the DOM when the component loads on the browser. React has a hook for this scenario, like useEffect. The whole process can wrap within the hook and trigger when the component delivers for the first time and adds a new script.

Developers add a different range of scripts in real-world projects. They develop custom hooks and call them different times with diverse source links. Custom hooks store in a separate directory in the/src folder. 

import { useEffect } from 'react';
export default function useExternalScripts({ url }){
useEffect(() => {
const head = document.querySelector("head");
const script = document.createElement("script");
script.setAttribute("src", url);
head.appendChild(script);
return () => {
head.removeChild(script);
};
}, [url]);
};
In the component, you can add a new script in the file.
import useExternalScripts from "./hooks/useExternalScripts"
const Component = () => {
useExternalScripts("https://www.scriptdomain.com/script")
...
}

The new script can append to the page head whenever the component is mounted in DOM. The script can be eliminated when a component unmounts. Never use return snippets whether the script can use different components across the app. 

Function go back by the hook is a cleanup function that executes when the component unmounts. Developers don’t need it whether they use sources at several places. When running an application, developers must check and examine all necessary scripts. 

Alternating option:

Using a react helmet is ideal for managing changes within the head tag. The helmet takes complete care of the script if it is placed within it. 

import { Helmet } from "react-helmet"
export default function Component() {
return (
<> 
<Helmet>
<script
src="https://www.myscripts.com/scripts"
crossorigin="anonymous"
async
></script>
</Helmet>
...
</>
)
}

Important components used in the app:

Before working with React, you need to understand important components use in the app. You can pay attention to vital guidelines to add a script tag. 

Master page:

The master page lets individuals design the perfect layout for the web pages. Moreover, the master web page describes the look, feel and standard behavior. With it, you can develop pages that comprise content you wish to show.

Stateless execution:

When users ask for the individual content page, the web app combines with the master page efficiently. It gives the exact outcome. Certainly, merge master page layout with content display ideal output. 

• React helps developers to use several options to show data.
• Developers have a great chance to retrieve and store data.
• In the React app, they utilize data-bound control to automate data presentation and input.
• For good automation, they take necessary UI elements, including drop-down lists, text boxes, and tables.

Client script and framework:

In React, client-script functionality enables users to boost diverse features. If you want a richer and responsive user interface, you can utilize client script due to it lets asynchronous calls to the server.

Membership:

React is a reliable framework for creating a perfect web app with proper user credentials. Whether you log into a web app, the database can be read. Account folders like files that are implemented by diverse parts of membership involve registering, logging in, authorizing access, and altering password. Web form bears path and openID.

Authentication lets users log in to the site from Facebook, Twitter, Google, and Windows Live. Template default utilizes database names to form different database membership. The development of the database server comprises Studio Express. 

Conclusion:

Overall, you can understand the above solution carefully and add a script tag easily to react. InnerHTML is the main element to manipulate nodes on browser DOM. For security reasons, developers don’t use script tags in innerHTML. 

You can spend time and hire dedicated react developer to deal with app development efficiently. Inserting a new script tag and appending it to the head element is a great approach to adding a script tag in the app. React Helmet is also the perfect library to attain the same thing.
