gw3-sdk-js

This repository contains the JavaScript SDK for Gateway3, an decentralized IPFS gateway. The Gateway3 SDK provides a simple and easy-to-use interface to interact with IPFS, enabling developers to build scalable and distributed applications.

Requirements

• Node.js v14.0.0 or above, or modern web browsers (Chrome 60+, Firefox 53+, Safari 10.1+, Edge 15+)
• Access key and secret from Gateway3

Installation

To install the IPFS Gateway SDK, use the following command:

npm install gw3-sdk

Usage

Import the IPFS Gateway SDK in your JavaScript project:

import { Client } from 'gw3-sdk'

Use new Client to create a new Gateway3 client with the provided access key and access secret.

Here's a simple usage example:

import { Client } from 'gw3-sdk';

let client = new Client('YOUR-ACCESS-KEY', 'YOUR-ACCESS-SECRET');

// Replace 'YOUR-FILE' with the file you want to upload
let file = 'YOUR-FILE';
let hooks = {
  onProgress: (event) => console.log(`Upload progress: ${event.percent}%`),
  onSuccess: (body) => {
    console.log('Upload success', body);
    // After file is uploaded, pin the file using its CID.
    client.addPin(body.cid)
      .then(() => console.log(`File with CID ${body.cid} has been pinned successfully.`))
      .catch((error) => console.log(`Error in pinning file with CID ${body.cid}:`, error));
  },
  onError: (error) => console.log('Upload error', error),
};

client.uploadFile(file, hooks);

uploadFile

Uploads the given data to Gateway3 and returns the corresponding CID.

async function uploadFile(file: File, hooks?: Hooks) : Promise<{ cid: string }>

interface Hooks {
  onProgress?: (event: ProgressEvent) => void
  onSuccess?: (body: any) => void
  onError?: (error: Error) => void
}
interface ProgressEvent {
  percent?: number
}

getIpfs

Retrieves data from the Gateway3 for the given CID.

async function getIpfs(cid: string)

addPin

Requests Gateway3 to pin the given CID.

async function addPin(cid: string)

removePin

Requests Gateway3 to unpin the given CID.

async function removePin(cid: string)
