@numbersprotocol/estuary-upload

estuary-upload

Upload your file to Estuary and generate Numbers ID (Nid, the same as default IPFS CIDv1).

If you upload a file to Estuary and find the CIDv1 is different from Kubo (IPFS implementation in Go) CIDv1, it is because both Kubo and Estuary generate CIDv1, but they use different chunk sizes: Kubo (256 KB) vs Estuary (1 MB). estuary-upload helps you generate Nid (Kubo CIDv1) in any file size.

Installation

yarn global add @numbersprotocol/estuary-upload

Usage

In code

Add from path

import { Estuary } from 'estuary-upload';

const estuary = new Estuary('<api-key>');
const cid = await estuary.addFromPath('my-file.jpg');
console.log(
  `The file is uploaded to Estuary with CID ${cid} preserved!`
);

Add from Nid (Kubo CIDv1)

import { Estuary } from 'estuary-upload';

const estuary = new Estuary('<api-key>');
const cid = await estuary.addFromCid(
  'bafkreia2254bseihmsqw7fzxsk54p7nqmitn2ibhnjiafxtql6by54idv4'
);
console.log(
  `The file is uploaded to Estuary with CID ${cid} preserved!`
);

Add from buffer

import { Estuary } from 'estuary-upload';

const estuary = new Estuary('<api-key>');
const cid = await estuary.addFromBuffer(new Uint8Array([21, 31, 41]));
console.log(
  `The file is uploaded to Estuary with CID ${cid} preserved!`
);
