TypeScript is great for large-scale web applications, as you can write frontend and backend code with it. On the backend, you need to install a library called ts-node to execute TypeScript code in a Node.js environment.
Also, TypeScript allows using some ES6 and ES7 candidate features not yet supported by major browsers. For example, the optional chaining operator and class constants were available in TypeScript long before ECMAScript officially supported them.
When Shouldn’t You Use TypeScript for a New Project?Even if TypeScript is generally fantastic, there are still reasons why I wouldn’t recommend using it. The biggest reason not to use TypeScript is if you or your team have to respect a tight deadline. Deadlines are stressful enough, and adding a new technology that you have no experience working with isn’t recommended. Unfortunately, learning TypeScript takes time, and this time may be better spent elsewhere for projects with a deadline. Also, TypeScript can be challenging to configure, especially for beginners. It may require installing multiple npm libraries and working with a bundler (like webpack). If you aren’t prepared to spend the time learning all of this new information, don’t use it. Another thing to consider is that using TypeScript will increase the developers’ entry threshold. If the project is open-source, this can increase developers’ difficulty in contributing to it. Also, for managers and hiring personnel, using TypeScript in a project means that the developers you hire must have experience using TypeScript or another OOP language. Adopting TypeScript raises the minimum job qualification to work on the project and can increase the project’s budget, because you need to hire more experienced developers.
.ts, and fixing the errors outputted by the TypeScript compiler.
Another option is to keep the legacy code and only write new features in TypeScript. When a feature touches a part of the legacy code, you can migrate it simultaneously while working on it.
Is TypeScript good for large projects?
Yes, TypeScript is particularly well-suited for large projects. Its features like static typing, interfaces, and classes can make the code more organized, easier to understand, and easier to maintain, which are all crucial for large-scale development.
Is TypeScript widely used in the industry?
Yes, TypeScript is widely used in the industry. Many large companies, including Microsoft, Google, and Airbnb, use TypeScript for their large-scale projects due to its scalability and improved tooling.
