TypeScript is a strongly typed programming language that builds on JavaScript, giving you better tooling at any scale. GenAIScript scripts can be authored in TypeScript.

You can convert any existing script to typescript by changing the file name extension to .genai.mts.

def("FILE", files)
$`Summarize each file. Be concise.`

It is possible to import TypeScript source file.

export function summarize(files: string[]) {
    def("FILE", files)
    $`Summarize each file. Be concise.`
}

• import

import { summarize } from "./summarizer.mts"
summarize(env.generator, env.files)

Yes and No.

Most modern editors, like Visual Studio Code, will automatically type-check TypeScript sources.

You can also run a TypeScript compilation using the scripts compile command.

However, at runtime, GenAIScript converts TypeScript to JavaScript without type checks through tsx.
