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:

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