TypeScript

Page summary:

TypeScript adds a type system layer to Strapi applications, enabling type-safe code and automatic type generation. Create a new TypeScript project with the --typescript flag or add TypeScript support to an existing project.

4.3.0This feature requires Strapi version 4.3.0 or later.

TypeScript adds an additional type system layer above JavaScript, which means that any valid JavaScript code is also valid TypeScript code. In the context of Strapi development, TypeScript allows for a more type-safe codebase for your application, and provides you with a set of tools for automatic type generation and autocompletion.
