Language Support: TypeScript

[dylburger]

I'd like to author TypeScript code steps on Pipedream, similar to how I can choose to "Run Node.js code" today.

Bumping 😃

Hello @todsac, any plans for getting this prioritized?

[dylburger]

@hhimanshu this isn't on the immediate roadmap, but we hear you and plan to add support for other languages like TypeScript in the future!

For anyone looking to get Typescript support - you can get it by compiling your TS into a commonjs module, then uploading that to pipedream via cli. Something like this:

// myAction.ts
export default {
  name: "GBucket - Upload File",
  description: "Uploads a file to a GBucket route",
  key: "myGBucketUploader",
  version: "1.0.0",
  type: "action",
  props: {
    googleCloud: {         // passed in app object https://pipedream.com/docs/apps/all-apps/#apps
      type: "app",
      app: "google_cloud",
    },
    webhookTrigger: {    // passed in param https://pipedream.com/docs/workflows/steps/params/#entering-expressions
      type: "object",      
    },
  },
  async run() {

      // access your passed in variables, which can come from a previous code step
      const { myData } = (this as any).webhookTrigger.object;

     // access your auth passed in from apps
     const { Storage } = require("@google-cloud/storage");
     const key = JSON.parse((this as any).googleCloud.$auth.key_json);
    const storage = new Storage({
      projectId: key.project_id,
      credentials: {
        client_email: key.client_email,
        private_key: key.private_key,
      },
    });
    await storage.upload(myData)

  }
}

// rollup.config.js (or webpack.config.js)
const configAction = {
  input: "src/actions/myAction.ts",
  output: {
    file: "lib/actions/myAction.js",
    format: "cjs",
    sourcemap: true,
    exports: "default",
  },
  plugins: [
    commonjs(), // enable CommonJS modules
    nodePolyfills(), // enable NodeJS polyfills
    resolve({ preferBuiltins: true, browser: true }), // enable importing from node_modules
    typescript(), // enable TypeScript
    json(), // enable JSON
    globals(), // allows globals to be imported (process.env)
    builtins(), // allows builtins to be imported via require/import
  ],
};

echo "Deploying Pipedream..."
yarn build
NODE_ENV=production pd publish ./lib/actions/myAction.js

Which will end up looking like re-useable action this in the Pipedream UI.

Typescript. Yes please.

Powered by Deno and able to define the type that the code block will receive would be 🎉
