Web3 Ipfs

Description

Experience seamless file management on our IPFS host with our SDK. Utilize API keys to effortlessly pin, unpin, retrieve, and securely access files through the gateway, ensuring efficient and secure file operations. Simplify decentralized file management with ease and confidence.

Installation

npm install ipfs-sdk

Setup

To start, simply require the W3IPFS SDK and set up an instance with your W3IPFS API Keys or your JWT key. Don't know what your keys are? Check out your Account Page. In the example below we provided with 2 ways to call the W3IPFS SDK.

// Use the api keys by providing the strings directly 
import W3IpfsClient from 'ipfs-sdk';
const client = new W3IpfsClient("key", "secret-key")

// Use the api keys by specifying your api key and api secret
import W3IpfsClient from 'ipfs-sdk';
const client = new W3IpfsClient({pinningApiKey: "key", pinningSecretApiKey: "secret-key"})

Quickly test that you can connect to the API with the following call:

client.testAuthentication().then((result) => {
    //handle successful authentication here
    console.log(result);
}).catch((err) => {
    //handle error here
    console.log(err);
});

Usage

Once you've set up your instance, using the W3IPFS SDK is easy. Simply call your desired function and handle the results of the promise.

    metadata: {
        name: string,
        keyvalues: {

        }
    }
}
