JS Task API Examples: switching to mainnet

This section is aimed mainly at requestors wishing to switch from running simple test tasks on our testnet to launching production payloads utilizing the vast number of providers on the mainnet.

By default, the JS SDK will execute tasks on the testnet. It is a development network with a limited amount of providers and limited amounts of computational resources available. If you would rather need a larger amount of providers to compute on, you should switch to the mainnet.

In this article, we will show how to run your tasks on Polygon.

Yagna service is installed and running with the try_golem app-key configured.

Create a project folder, initialize a Node.js project, and install the @golem-sdk/golem-js library.

mkdir golem-example
cd golem-example
npm init
npm i @golem-sdk/golem-js

Copy the code into the index.mjs file in the project folder and run:

node index.mjs

In this example, we create the TaskExecutor with additional parameters that indicate we intend to run our task on the Polygon platform.

import { TaskExecutor } from "@golem-sdk/golem-js";

(async () => {
  const executor = await TaskExecutor.create({
    payment: { network: "polygon" },
    package: "529f7fdaf1cf46ce3126eb6bbcd3b213c314fe8fe884914f5d1106d4",
    yagnaOptions: { apiKey: "try_golem" },
  });

  const result = await executor.run(async (ctx) => (await ctx.run("node -v")).stdout);
  await executor.end();

  console.log("Task result:", result);
})();

In the script output, you can see that now the network is a Polygon.
