+### Typescript
+
+Gitea is in the process of migrating to type-safe Typescript. Here are some specific guidelines regarding Typescript in the codebase:
+
+#### Use type aliases instead of interfaces
+
+Prefer to use type aliases because they can represent any type and are generally more flexible to use than interfaces.
+
+#### Use separate type imports
+
+We use `verbatimModuleSyntax` so type and non-type imports from the same file must be split into two `import type` statements. This enables the typescript compiler to completely eliminate the type import statements during compilation.
+
+#### Use `@ts-expect-error` instead of `@ts-ignore`
+
+Both annotations should be avoided, but if you have to use them, use `@ts-expect-error` because it will not leave ineffective statements after the issue is fixed.
+
 ### `async` Functions
 
 Only mark a function as `async` if and only if there are `await` calls
