BWS IPFS SDK

Official Blockchain Web Services IPFS solution NodeJS SDK.

Overview

Blockchain Web Services (BWS) is a comprehensive platform offering a suite of blockchain-based solutions, designed to simplify and enhance the integration of blockchain technology into various business and individual needs.

This SDK provides the easiest way to save data into the InterPlanetary File System (IPFS). Use it to save your NFT metadata and images.

Installation

npm install --save @bws-sdk/ipfs

How to use it

Once installed, just import the SDK, create an instance using your API Key and start using the available functions. To get your API Key go to www.bws.ninja and sign up - it's free.

import { BWSIPFS } from @bws-sdk/ipfs;
const ipfs = new BWSIPFS('<your API key>')

Operations

Use the following available operations:

• uploadJSONAsync to save JSON data (e.g. NFT Metadata),
• uploadFileAsync to upload images or PDF files, or
• uploadStreamAsync if you need to pass a stream for sending your file(s).

All the operations will return the following IPFS related information (pointing to your newly created IPFS file):

{
    "cid": "QmU7avmnTb4iVbNGCHMJmdEbsx9nRtUx7dWGpKeE7zjo8T",
    "uris": {
        "ipfs": "ipfs://QmU7avmnTb4iVbNGCHMJmdEbsx9nRtUx7dWGpKeE7zjo8T",
        "url": "https://ipfs.bws.ninja/ipfs/QmU7avmnTb4iVbNGCHMJmdEbsx9nRtUx7dWGpKeE7zjo8T"
    }
}

uploadJSONAsync

Upload a JSON to IPFS. You can pass the JSON object or the string representation.

import { BWSIPFS } from @bws-sdk/ipfs;
const ipfs = new BWSIPFS('<your API key>')

await ipfs.uploadJSONAsync({ timestamp: Date.now() }).then(data => {
    console.log(data);
}).catch(err => {
    console.log(err);
});

uploadFileAsync

Upload a file to IPFS by indicating the file path.

import { BWSIPFS } from @bws-sdk/ipfs;
const ipfs = new BWSIPFS('<your API key>')

await ipfs.uploadFileAsync('./files/image.png').then(data => {
    console.log(data);
}).catch(err => {
    console.log(err);
});

uploadStreamAsync

Upload content to IPFS by passing a stream.

import fs from 'fs';

import { BWSIPFS } from @bws-sdk/ipfs;
const ipfs = new BWSIPFS('<your API key>')

await ipfs.uploadFileAsync(fs.createReadStream('./files/image.png').then(data => {
    console.log(data);
}).catch(err => {
    console.log(err);
});
