Bun reads the paths field in your tsconfig.json to re-write import paths. This is useful for aliasing package names or avoiding long relative paths.

tsconfig.json

{
  "compilerOptions": {
    "paths": {
      "my-custom-name": ["zod"],
      "@components/*": ["./src/components/*"]
    }
  }
}

With the above tsconfig.json, the following imports will be re-written:

tsconfig.ts

import { z } from "my-custom-name"; // imports from "zod"
import { Button } from "@components/Button"; // imports from "./src/components/Button"

See Docs > Runtime > TypeScript for more information on using TypeScript with Bun.
