And this is done by declaring the types - the compile type declarations first. The code above can be cleaner and more readable if we separate the runtime and compile-time declarations. Declare types before runtime implementation In the code above, by setting esModuleInterop to true we enable allowSyntheticDefaultImports which is important for TypeScript to support our syntax. Note: To use this option, we need to configure the tsconfig.json file as seen below: With this approach, we can destructure what we need from the react module instead of importing all the contents. A better pattern is to use default export as seen below: While the code above works, it is confusing and not a good practice to import all the contents of React if we are not using them. Now let’s learn about the ten useful patterns to apply when using React and Typescript:īelow are ten useful patterns to apply when using React and Typescript: 1. Track and manage actionable issues that are linked to code, directly from the IDE.
💡 To make it easier for your team to keep codebase healthy and prioritise technical debt work, try using Stepsize.
In this article, we would look at some useful patterns to use when working with React and TypeScript. And this is because the principles involved in writing clean code, eliminates technical debts. Consequently, clean code can lower the cost of software development. Writing clean code involves writing codes with clear and simple design patterns that makes it easy for humans to read, test and maintain. Anyone can write code that a computer can understand but good developers write clean code – code that humans can understand.Ĭlean code is a reader-focused development style that improves our software quality and maintainability. As a JavaScript library, React inherits this problem.Ĭlean code is a consistent style of programming that makes your code easier to write, read, and maintain. The result of this is that JavaScript errors are caught very late and this can lead to nasty bugs. JavaScript is a loosely typed language, and as a result, it catches runtime. React is a JavaScript library, and it is the most popular and industry-leading frontend development library today.
