Sample action with Typescript and parcel.

Run npm install && npm run build && pd publish dist/main.js to try it out.

This example also uses @planet-a/parcel-optimizer-versioned-imports to version imports when possible.

index.ts

import { defineAction } from "@pipedream/types";
import assert from "node:assert";

export default defineAction({  
  name: "My Action",
  version: "0.0.1",
  key: "my-key",
  description: "Example",
  props: {},
  type: "action",
  methods: {},
  async run(options) {
    assert(options);
    const { $ } = options;

    $.export("$summary", ":tada:");
    $.export("hello", "world");
  },
});
