So, let’s dive in and examine the key factors that can help you determine which is better suited for your React projects.
What Is TypeScript?
dynamically without the need to reload the entire page.
It is a new technology as compared to other technologies. There are many benefits of using React, one of the reasons for it coming into so much popularity; it makes it easier to make dynamic web apps as it requires less code, has reusable codes, dedicated tools for debugging, and many more.
- Tooling & IDE Support: TypeScript provides robust tooling and excellent support in popular IDEs. It offers features like autocompletion, code navigation, and refactoring capabilities, which can enhance developer productivity and reduce the likelihood of introducing bugs.
- Scalability: As projects grow in size and complexity, TypeScript’s static typing can help prevent certain bugs and simplify refactoring code. It provides better code organization and documentation through interfaces, type annotations, and generics.
Use Case Example for React Better with TypeScript
Imagine you’re part of a development team working on a large-scale e-commerce platform using React. The project involves multiple team members collaborating on different components and functionalities. In such a scenario, TypeScript can bring significant benefits. Its static typing feature helps catch potential type-related errors during development, making the code more robust and maintainable. With TypeScript’s strong tooling and IDE support, developers can use autocompletion, code navigation, and refactoring capabilities, improving productivity and reducing the chances of introducing bugs. Furthermore, as the project scales in complexity, TypeScript’s static typing provides better code organization and documentation through interfaces, type annotations, and generics. Considering this project’s size, complexity, and team collaboration aspect, using TypeScript with React would be a favorable choice.
Tooling and Autocomplete
Ecosystem and Library Support
JavaSript is more popular in the field of app development, as per the survey report of StackOverflow. It can not only be used for native mobile and desktop development but also is used for developing browser-based apps and websites. Since the typescript was released in the year 2013, it has become one of the preferred choices of many developers due to its easier syntax and scalability.
|Tooling Support||Excellent tooling support with TypeScript compiler (tsc) and IDE integration||Simpler setup, no additional type checker required|
|Complexity||Adds complexity due to managing types, generics, and interfaces||Simpler without the need to define types explicitly|
|Development Speed||Initial slowdown due to writing types, but can lead to faster development in the long run||Faster initial development, but may lead to more runtime errors|
|Strictness and Flexibility||Enforces stricter rules on code, reducing flexibility in some cases||Allows more flexibility and may lead to potential runtime errors|
Best Practices for React Development
Some of React’s best practices you should follow to improve the performance of your application are listed below-
1. Avoid Repetitive Code
If you find that you are writing duplicate code, make the code into reusable components.
Instead of continuously writing the code in every component that needs a menu, it makes more sense, for instance, to construct a component for your navigation menu.The benefit of a component-based architecture is that. Your project can be divided up into manageable pieces that you can utilize throughout your application.
2. Opt for Fragments instead of Divs where possible
The code returned by React components must be contained in a single element, most frequently a div or a React fragment. You should opt for fragments where possible.
Using div> expands the DOM, especially in large projects, since the more tags or DOM nodes your website has, the more memory it requires and the more energy a browser must expend to load it. This causes a slower website load time and a possibly worse user experience.
3. Avoid Using State
React state maintains a record of the data, and when it changes, it causes the React component to render again. Avoid utilizing state as much as possible while developing React applications since the more state you use, the more data you have to manage across your project.
Declaring a state only when necessary is one method of reducing its usage. If you are retrieving user data from an API, for instance, keep the entire user object in the state rather than just the individual properties.
4. Write tests for each React component
Create tests for the components you make to lessen the likelihood of mistakes. Testing guarantees that the parts behave as you would anticipate. Jest, one of the most popular testing frameworks for React, offers a setting in which you may run your tests.
5. Use Object Destructuring for Props
Use object destructuring to pass the prop name rather than the props object. By doing this, you no longer need to look for the props object every time you need to utilize it.
How to Create a React Project in Typescript?
To Create a React Project in TypeScript, Follow These Steps:
- Open your terminal or command prompt.
- Run the following command to create a new React project with TypeScript:
npx create-react-app my-app --template typescript
or if you prefer to use Yarn:
yarn create react-app my-app --template typescript
This command will create a new directory called
my-app (you can replace
my-app with the name you prefer) and set up a new React project with TypeScript.
- Once the project creation process is complete, navigate to the project directory:
- You can now start the development server by running the following command:
or if you’re using Yarn:
This will start the development server and open your React application in a web browser. You can begin editing the TypeScript files in the src directory and see the changes live-reloaded in the browser.
That’s it! You have successfully created a React project with TypeScript. You can start building your application using React components and TypeScript type annotations.
Reasons You Should Use TypeScript With React
Here are some reasons why you should use TypeScript with React-
1. Improved IDE support
Different code editors like Visual Studio Code, Atom, and Sublime Text are compatible with TypeScript. Better code completion recommendations, error checking, and refactoring capabilities are made possible by TypeScript’s static typing characteristics.
2. Type Safety
Developers can identify type-related issues at compile time rather than during runtime because of TypeScript’s type system. High-quality code is simpler to write and maintain thanks to this functionality. For instance, TypeScript can assist in identifying mistakes in a React component’s props and state.
3. Easier Collaboration
Code can be written in a more organized manner with TypeScript, which facilitates developer collaboration. The time and effort needed to comprehend and manage complicated codebases is reduced as a result.
4. Better Performance
5. Easier Refactoring
TypeScript makes easy renaming of the variables and functions in a large codebase by automatically updating references to those variables or functions.
6. Code Documentation
Typescript allows developers to make their code with JSDoc comments. This makes it easier for the developers to understand the code and collaborate on projects.
7. Improved Scalability
It can be really difficult to keep track of all the variables and functions in the codebase once the project starts to grow more and more. With the help of the Typescript, it becomes easier to manage and scale the projects by providing more structure and organization.
8. Improved Code Quality
With the Typescript, developers can write cleaner, more efficient, and more maintainable code as it enforces strict type checking and other best practices.
9. Reduced Maintenance Costs
TypeScript code is more maintainable and predictable, which leads to less time and effort to debug and maintain. So over the lifetime of the project, it can lead to significant cost savings.
10. Better Error Handling
In the development process itself, the Typescript allows the developer to catch errors early. It helps in preventing runtime errors and makes debugging easier.
