React is one of the common forms to build an application with present technology evolution. React hooks have evolved with the advanced betterment of React with the latest Javascript. The app development companies are frequently using hooks for application building and development. 

Typescripts ensure the proper usage of hooks in React. Typescript is the novel method used for front-end development which upgrades the skills of the front-end development team. Hence, in the current application development scenario, Typescript and React hooks are two important components that must be included according to the requirement. 

In React, hooks are used for improvement in code relativity. Further, in this article, we will study more about the React hooks and typescripts using them collectively to write different codes. You can hire react develop from for front-end application development for your enterprise. 

React Hooks: An Overview

React hooks are considered to be the functional element with a stateless format. The functional components are upgraded as container components which are quite time-consuming and complex. 

React hooks handles both functions by maintaining the uniform motion and writing the simplified codes with typescript assistance. According to the many expert developers, writing the React codes with Typescript is an attractive and convenient experience for the developer. 

Considering the common example of integrating the local state with a basic component which React hooks handles the quotation: 

// put signature in local state and toggle signature when signed changesfunction QuotationSignature({quotation}) {
   const [signed, setSigned] = useState(quotation.signed);   useEffect(() => {       fetchPost(`quotation/${quotation.number}/sign`)   }, [signed]); // effect will be fired when signed changes
   return <>       <input type=”checkbox” checked={signed} onChange={() => {setSigned(!signed)}}/>       Signature   </>}

About Typescript: 

Typescript is the most recent attraction of Javascript, which provides the advanced methods to integrate error-free coding, simplified documentation with variation authority, and type checking during the run time. Recently, the trend of using React with Typescript is leveraging and becoming a simplified aspect for front-end developers. 

The Process To Use React Hooks With Typescript: 

Below is the process mentioned to use React with Typescript: 


Here the project is started, and being the initial stage, you have to provide the name of the projects and other imperative details needed. The initial coding is according to the below-mentioned coding pattern:

cd typescript-with-react/code .npm start

In this coding, the file name will have a .tsx or .ts extension, reflecting the transpiled files in Typescript. 

Handling State:

While writing the React codes in Typescript, it becomes necessary to mention the definition of types and variables with their associate returns and functions. Below is the process description: 

  • Create interface denoting data type of associate variables
  • Within the interface, mention the definition of the desired state of variables and additional elements like a square bracket with specified format and values. 

inputValue:number | string | null

This coding mentions the data type, numeral, string, and even the null value added to the interface. 

Prop Handling: 

For prop handling in React, there is a need for a prior declaration about the valuation, type, number, and definition of variables in both receiving and sending phases. The support of Typescript with notify the error if any detail is detected missing. 

The sending phase coding is framed as:

<List form={form}/><Form form={form} setForm={setForm} />The receiving side codes will look like:import { IState as IProps } from “../App”
const List: React.FC<IProps> = ({ form }) => {…}

After acceptance of forms of variables definition in the React form with accepted props are wrriten with code:

setForm: React.Dispatch<React.SetStateAction<Props[“form”]>>

Function Handling: 

Using the React with Typescript, mentioning the output of each function involved becomes necessary. Below is the process of integrating the functions by mentioning their output. 

  • Add JSX.Element[] post parameters which reflect the function of JSX array. Write the nested return statement mentioning the mapping function to get the pure JSX functions.

Below are the codes: 

const randomFunction = (): void => {…}

Event Handling: 

Event handling in React Typescript is according to the DOM event with JSX files. Below is the pattern mentioned: 

<input className=”inputBox” type=’text’ name=”name” value={} onChange={(e) => handleChange(e)} /><textarea className=”inputBox” name=”review” value={} onChange={(e) => handleChange(e)}></textarea>

The input tag attains a DOM property where the call handle change option triggers the event. For such action, a function must be created that receives an HTML element in specific parameters. Below is the coding mentioned for this: 

const handleChange = (e: React.ChangeEvent<HTMLInputElement | HTMLTextAreaElement>): void => {        setInput({            …input,            []:        })    }

Benefit Of Using Typescript With React Hooks:

The major benefit of using this combination is splitting the quotationstate into two distinct formats. When integrated into codes, it looks like this: 

interface QuotationProps{   quotation:Quotation;}function QuotationPage({quotation}:QuotationProps){   const [quotation, setQuotation] = useState(quotation);   const [signed, setSigned] = useState(false);}


These are the basic detail about React Hooks and Typescripts which are collectively used for writing the script with minimum errors. This novel element of Javascript has transformed the front-end development with advanced and fast processing with a zero-error policy. Using Typescript with React s becoming a futuristic trend to develop a customized and advanced front-end interface. Get custom react solutions at Bosc Tech Labs with our experienced react developers.
