Use the Solana docs and examples here if you need help. We're going to focus on ShdwDrive 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.
Building components for various ShdwDrive operations
Let's start by instantiating the ShdwDrive connection class object. This will have all ShdwDrive 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 ShdwDrives upon wallet connection. This can be done with the useEffect React hook.
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.
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.
constaccts=awaitdrive.getStorageAccounts("v2");// handle printing pubKey of first storage acctlet acctPubKey =newanchor.web3.PublicKey(accts[0].publicKey);console.log(acctPubKey.toBase58());
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.
key: A PublicKey object representing the public key of the Shdw 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.
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:
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.
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.
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.
This method is used to create a new instance of the ShdwDrive class. It accepts a web3 connection object and a web3 wallet. It returns an instance of the ShdwDrive class.
// Javascript SDK example using the constructor method// this creates a new instance of the ShadowDrive class and initializes it with the given connection and wallet parametersconstshadowDrive=newShadowDrive(connection, wallet).init();
addStorage
