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.`);
    },
  }
);

Checkout our Storage SDK Documentation for more info.

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.`);
  },
});
 
...
