Using Node.js SDK

Using Node.js SDK to Update Content with Lighthouse IPNS

Step 0: Get API keys from Lighthouse as explained in the main tutorial.

Step 1: Import the Lighthouse package and set up your API key:

import lighthouse from '@lighthouse-web3/sdk';
const apiKey = process.env.API_KEY; // Replace this with your actual API key

Step 2: Generate an IPNS key using the Lighthouse SDK:

const keyResponse = await lighthouse.generateKey(apiKey);
console.log(keyResponse.data);

This will return an IPNS name and ID, which we will use in the next steps.

Step 3: Publish the content using the generated IPNS key and the CID:

const pubResponse = await lighthouse.publishRecord(
  "QmWC9AkGa6vSbR4yizoJrFMfmZh4XjZXxvRDknk2LdJffc",
  keyResponse.data.ipnsName,
  apiKey
);
console.log(pubResponse.data);

You will receive a response containing the IPNS name and the link to access the published content.

Step 4: Get all IPNS keys associated with your Lighthouse account:

const allKeys = await lighthouse.getAllKeys(apiKey);
console.log(allKeys.data);

This step allows you to retrieve a list of all IPNS keys associated with your account.

Step 5: (Optional) Remove an IPNS key:

const removeRes = await lighthouse.removeKey(keyResponse.data.ipnsName, apiKey);
console.log(removeRes.data);

This step enables you to remove an IPNS key if necessary.
