Editing Content

This guide will walk you through editing content on the Lens Storage Nodes.

For editing files or folders the link_hash addressing is used.

If a link_hash resolves to a folder the entire folder will be replaced and all existing files within the same folder will be deleted.
If a link_hash resolves to a file, the file will be replaced by the new one.

Assuming you have a signer instance that satisfies the Signer interface.

interface Signer {  signMessage({ message }): Promise<string>;}

Viem's WalletClient class satisfies the Signer interface.

Define the ACL template for the update:

import { AclTemplate } from "@lens-protocol/storage-node-client";
const acl: AclTemplate = {  template: "lens_account",  lensAccount: "0x6982508145454Ce325dDbE47a25d4ec3d2311933",};

Then, edit the file from its lens:// URI as follows:

const updated = new File(  ["Ehlo Lens Storage, wen contents ?"],  "ehlo-lens-storage.txt",  {    type: "text/plain",  });
const success = await storageClient.editFile("lens://af5225b…", updated, signer, { acl });\
console.log(success); // true

That's it—you successfully edited the resource on the Lens Storage Nodes.
