# How to upload to IPFS using Spheron SDK?

# 1. Spheron Storage SDK (for Nodejs environments)

# Installation

npm i @spheron/storage

# Usage

import { SpheronClient, ProtocolEnum } from '@spheron/storage'

const client = new SpheronClient({ token })

let currentlyUploaded = 0

const { uploadId, bucketId, protocolLink, dynamicLinks } = await client.upload(
  filePath,
  {
    protocol: ProtocolEnum.IPFS,
    name,
    onUploadInitiated: uploadId => {
      console.log(`Upload with id ${uploadId} started...`)
    },
    onChunkUploaded: (uploadedSize, totalSize) => {
      currentlyUploaded += uploadedSize
      console.log(`Uploaded ${currentlyUploaded} of ${totalSize} Bytes.`)
    }
  }
)

# 2. Spheron Browser Upload SDK (for Browser environments)

# Installation

npm i @spheron/browser-upload

# Usage

# Server

You have to set up a web server with an endpoint that will be used by the frontend to fetch the token for upload.

import { SpheronClient, ProtocolEnum } from "@spheron/storage";

...

app.get("/initiate-upload", async (req, res, next) => {
  try {
    const bucketName = "example-browser-upload"; // use your preferred name
    const protocol = ProtocolEnum.IPFS; // use your preferred protocol
    const token = process.env.SPHERON_TOKEN; // add your access token in .env or paste it here

    const client = new SpheronClient({ token });

    const { uploadToken } = await client.createSingleUploadToken({
      name: bucketName,
      protocol,
    });

    res.status(200).json({
      uploadToken,
    });
  } catch (error) {
    console.error(error);
    next(error);
  }
});

# Client

You have to send a request to your server to create the uploadToken that will be used to upload files from the browser.

import { upload } from "@spheron/browser-upload";

...

const response = await fetch(`<BACKEND_URL>/initiate-upload`); // get the temporary access token from server
const resJson = await response.json();
const token =  resJson.uploadToken;

let currentlyUploaded = 0;

const { uploadId, bucketId, protocolLink, dynamicLinks } = await upload(files, {
  token,
  onChunkUploaded: (uploadedSize, totalSize) => {
    currentlyUploaded += uploadedSize;
    console.log(`Uploaded ${currentlyUploaded} of ${totalSize} Bytes.`);
  },
});
