Deno/typescript

Deno runtime

The DenoRuntime allows you to run lightweight and short-lived typescript function in a sandboxed environment. Permissions can be customized per typegraph and by default only include some HTTPs domains. It's a great way to implement custom logic and functions. All typegraphs can lazily spawn a web worker and get an incredible cold-start and continuous performance thanks to the V8 engine powering Deno.

Where ops.ts looks like:

// ops.ts

interface AddInput {
  a: number;
  b: number;
}
export function doAddition({ a, b }: AddInput) {
  return a + b;
}
