Getting Started: Javascript SDK

Let's scaffold a React app and add our dependencies

npx create-react-app shdwapp
cd shdwapp/
yarn add @shadow-drive/sdk @project-serum/anchor \
    @solana/wallet-adapter-base \
    @solana/wallet-adapter-react \
    @solana/wallet-adapter-react-ui \
    @solana/wallet-adapter-wallets \
    @solana/web3.js \
    @solana-mobile/wallet-adapter-mobile

Review the Solana Web3.js SDK and Solana API resources.

Instantiate the Wallet and Connection

Use the Solana docs and examples here if you need help. We're going to focus on Shadow Drive SDK in these docs, so if you need a primer on how to build a React site with Solana, we can refer you to other resources.

Solana example code:

Sample Code provided by Solana 
import { WalletNotConnectedError } from '@solana/wallet-adapter-base';
import { useConnection, useWallet } from '@solana/wallet-adapter-react';
 import { Keypair, SystemProgram, Transaction } from '@solana/web3.js';
 import React, { FC, useCallback } from 'react';
export const SendSOLToRandomAddress: FC = () => {
const { connection } = useConnection();
const { publicKey, sendTransaction } = useWallet();
const onClick = useCallback(async () => {
    if (!publicKey) throw new WalletNotConnectedError();

    // 890880 lamports as of 2022-09-01
    const lamports = await connection.getMinimumBalanceForRentExemption(0);

    const transaction = new Transaction().add(
        SystemProgram.transfer({
            fromPubkey: publicKey,
            toPubkey: Keypair.generate().publicKey,
            lamports,
        })
    );

    const {
        context: { slot: minContextSlot },
        value: { blockhash, lastValidBlockHeight }
    } = await connection.getLatestBlockhashAndContext();

    const signature = await sendTransaction(transaction, connection, { minContextSlot });

    await connection.confirmTransaction({ blockhash, lastValidBlockHeight, signature });
}, [publicKey, sendTransaction, connection]);

return (
    <button onClick={onClick} disabled={!publicKey}>
        Send SOL to a random address!
    </button>
);

};

Building components for various Shadow Drive operations

Let's start by instantiating the Shadow Drive connection class object. This will have all Shadow Drive methods and it implements the signing wallet within the class for all transactions.

At the simplest level, it is recommend for a React app to immediately try to load a connection to a user's Shadow Drives upon wallet connection. This can be done with the useEffect React hook.

import React, { useEffect } from "react";
import * as anchor from "@project-serum/anchor";
import {ShdwDrive} from "@shadow-drive/sdk";
import { useWallet, useConnection } from "@solana/wallet-adapter-react";

export default function Drive() {
    const { connection } = useConnection();
    const wallet = useWallet();
    useEffect(() => {
        (async () => {
            if (wallet?.publicKey) {
                const drive = await new ShdwDrive(connection, wallet).init();
            }
        })();
    }, [wallet?.publicKey])
    return (
        <div></div>

This can be done with a NodeJS + TypeScript program as well.

const anchor = require("@project-serum/anchor");
const { Connection, clusterApiUrl, Keypair } = require("@solana/web3.js");
const { ShdwDrive } = require("@shadow-drive/sdk");
const key = require("./shdwkey.json");

async function main() {
    let secretKey = Uint8Array.from(key);
    let keypair = Keypair.fromSecretKey(secretKey);
    const connection = new Connection(
        clusterApiUrl("mainnet-beta"),
        "confirmed"
    );
    const wallet = new anchor.Wallet(keypair);
    const drive = await new ShdwDrive(connection, wallet).init();
}

main();

Create a Storage Account

This implementation is effectively the same for both Web and Node implementations. There are three params that are required to create a storage account:

  • name: a friendly name for your storage account
  • size: The size of your storage accounts with a human readable ending containing KB, MB, or GB
  • version: can be either v1 or v2. Note - v1 is completely deprecated and you shuold only use v2 moving forward.
//create account
const newAcct = await drive.createStorageAccount("myDemoBucket", "10MB", "v2");
console.log(newAcct);

Get a list of Owned Storage Accounts

This implementation is effectively the same for both Web and Node implementations. The only parameter required is either v1 or v2 for the version of storage account you created in the previous step.

const accts = await drive.getStorageAccounts("v2");
// handle printing pubKey of first storage acct
let acctPubKey = new anchor.web3.PublicKey(accts[0].publicKey);
console.log(acctPubKey.toBase58());

Full Response:

Output 
[
  {
    publicKey: PublicKey {
      _bn: <BN: c9217d175c7257f52a64cb9faa203e65487343720441cef2d9abcb3f8c706053>
    },
    account: {
      immutable: false,
      toBeDeleted: false,
      deleteRequestEpoch: 0,
      storage: <BN: a00000>,
      owner1: [PublicKey],
      accountCounterSeed: 0,
      creationTime: 1665690481,
      creationEpoch: 359,
      lastFeeEpoch: 359,
      identifier: 'myDemoBucket'
    }
  },
  {
    publicKey: PublicKey {
      _bn: <BN: 502aa038c1b95a8bc36c301f3ae06beda929ec3a044b0543e70d4378d4c574ea>
    },
    account: {
      immutable: false,
      toBeDeleted: false,
      deleteRequestEpoch: 0,
      storage: <BN: a00000>,
      owner1: [PublicKey],
      accountCounterSeed: 1,
      creationTime: 1665690563,
      creationEpoch: 359,
      lastFeeEpoch: 359,
      identifier: 'myDemoBucket'
    }
  }
]

Get a Specific Storage Account

This implementation is effectively the same for both Web and Node implementations. The only parameter required is either a PublicKey object or a base-58 string of the public key.

const acct = await drive.getStorageAccount(
    "EY8ZktbRmecPLfopBxJfNBGUPT1LMqZmDFVcWeMTGPcN"
);
console.log(acct);

Full Response:

Output

}

Upload a File

The uploadFile method requires two parameters:

  • key: A PublicKey object representing the public key of the Shadow Storage Account
  • data: A file of either the File object type or ShadowFile object type

Check the intellisense popup below when hovering over the method

File objects are implemented in web browsers, and ShadowFile is a custom type we implemented in TypeScript. So either you are using File in the web, or you are scripting in TS.

Here is an example with a React Component:

React Upload Component 
import React, { useState } from "react";
import { ShdwDrive } from "@shadow-drive/sdk";
import { useWallet, useConnection } from "@solana/wallet-adapter-react";
import FormData from "form-data";

export default function Upload() {
    const [file, setFile] = useState < File > undefined;
    const [uploadUrl, setUploadUrl] = useState < String > undefined;
    const [txnSig, setTxnSig] = useState < String > undefined;
    const { connection } = useConnection();
    const wallet = useWallet();
    return (
        <div>
            <form
                onSubmit={async (event) => {
                    event.preventDefault();
                    const drive = await new ShdwDrive(
                        connection,
                        wallet
                    ).init();
                    const accounts = await drive.getStorageAccounts();
                    const acc = accounts[0].publicKey;
                    const getStorageAccount = await drive.getStorageAccount(
                        acc
                    );

                    const upload = await drive.uploadFile(acc, file);
                    console.log(upload);
                    setUploadUrl(upload.finalized_location);
                    setTxnSig(upload.transaction_signature);
                }}
            >
                <h1>Shadow Drive File Upload</h1>
                <input
                    type="file"
                    onChange={(e) => setFile(e.target.files[0])}
                />
                <br />
                <button type="submit">Upload</button>
            </form>
            <span>You may have to wait 60-120s for the URL to appear</span>
            <div>
                {uploadUrl ? (
                    <div>
                        <h3>Success!</h3>
                        <h4>URL: {uploadUrl}</h4>
                        <h4>Sig: {txnSig}</h4>
                    </div>
                ) : (
                    <div></div>
                )}
            </div>
        </div>
    );
}

And a NodeJS + TypeScript implementation would look like:

TS UploadFile 
const { ShdwDrive, ShadowFile } = require("@shadow-drive/sdk");
/**
 * ...
 * Initialize storage account here...
 * ...
 */
const fileBuff = fs.readFileSync("./mytext.txt");
const acctPubKey = new anchor.web3.PublicKey(
    "EY8ZktbRmecPLfopBxJfNBGUPT1LMqZmDFVcWeMTGPcN"
);
const fileToUpload: ShadowFile = {
    name: "mytext.txt",
    file: fileBuff,
};
const uploadFile = await drive.uploadFile(acctPubKey, fileToUpload);
console.log(uploadFile);

Upload Multiple Files

This is a nearly identical implementation to uploadFile, except that it requires a FileList or array of ShadowFiles and an optional concurrency parameter.

Recall that the default setting is to attempt to upload 3 files concurrently. Here you can override this and specify how many files you want to try to upload based on the cores and bandwith of your infrastructure.

Delete a File

The implementation of deleteFile is the same between web and Node. There are three required parameters to delete a file:

  • key: the storage account's public key
  • url: the current URL of the file to be deleted
  • version: can be either v1 or v2
const url =
    "https://shdw-drive.genesysgo.net/4HUkENqjnTAZaUR4QLwff1BvQPCiYkNmu5PPSKGoKf9G/fape.png";
const acctPubKey = new anchor.web3.PublicKey(
    "EY8ZktbRmecPLfopBxJfNBGUPT1LMqZmDFVcWeMTGPcN"
);
const delFile = await drive.deleteFile(acctPubKey, url, "v2");
console.log(delFile);

Edit a File (aka Replace a file)

The editFile method is a combo of uploadFile and deleteFile. Let's look at the params:

  • key: the Public Key of the storage account
  • url: the URL of the file that is being replaced
  • data: the file that is replacing the current file. It must have the exact same filename and extension, and it must be a File or ShadowFile object
  • version: either v1 or v2
const fileToUpload: ShadowFile = {
    name: "mytext.txt",
    file: fileBuff,
};
const url =
    "https://shdw-drive.genesysgo.net/4HUkENqjnTAZaUR4QLwff1BvQPCiYkNmu5PPSKGoKf9G/fape.png";
const acctPubKey = new anchor.web3.PublicKey(
    "EY8ZktbRmecPLfopBxJfNBGUPT1LMqZmDFVcWeMTGPcN"
);
const editFile = await drive.editFile(acctPubKey, url, "v2", fileToUpload);

List Storage Account Files (aka List Objects)

This is a simple implementation that only requires a public key to get the file names of a storage account.

const acctPubKey = new anchor.web3.PublicKey(
    "EY8ZktbRmecPLfopBxJfNBGUPT1LMqZmDFVcWeMTGPcN"
);
const listItems = await drive.listObjects(acctPubKey);
console.log(listItems);

And the response payload:

{ keys: [ 'index.html' ] }

Increase Storage Account Size

This is a method to simply increase the storage limit of a storage account. It requires three params:

  • key: storage account public key
  • size: amount to increase by, must end with KB, MB, or GB
  • version: storage account version, must be v1 or v2
const accts = await drive.getStorageAccounts("v2");
let acctPubKey = new anchor.web3.PublicKey(accts[1].publicKey);
const addStgResp = await drive.addStorage(acctPubKey, "10MB", "v2");

Reduce Storage Account Size

This is a method to decrease the storage limit of a storage account. This implementation only requires three params - the storage account key, the amount to reduce it by, and the version.

const acctPubKey = new anchor.web3.PublicKey(
    "EY8ZktbRmecPLfopBxJfNBGUPT1LMqZmDFVcWeMTGPcN"
);
const shrinkAcct = await drive.reduceStorage(acctPubKey, "10MB", "v2");

Next you'll want to claim your unused SHDW

This method allows you to reclaim the SHDW that is no longer being used. This method only requires a storage account public key and a version.

const acctPubKey = new anchor.web3.PublicKey(
    "EY8ZktbRmecPLfopBxJfNBGUPT1LMqZmDFVcWeMTGPcN"
);
const claimStake = await drive.claimStake(acctPubKey, "v2");

Delete a Storage Account

As the name implies, you can delete a storage account and all of its files. The storage account can still be recovered until the current epoch ends, but after that, it will be removed. This implementation only requires two params - a storage account key and a version.

const acctPubKey = new anchor.web3.PublicKey(
    "EY8ZktbRmecPLfopBxJfNBGUPT1LMqZmDFVcWeMTGPcN"
);
const delAcct = await drive.deleteStorageAccount(acctPubKey, "v2");

Undelete the Deleted Storage Account

You can still get your storage account back if the current epoch hasn't elapsed. This implementation only requires two params - an account public key and a version.

const acctPubKey = new anchor.web3.PublicKey(
    "EY8ZktbRmecPLfopBxJfNBGUPT1LMqZmDFVcWeMTGPcN"
);
const cancelDelStg = await drive.cancelDeleteStorageAccount(acctPubKey, "v2");
