Update a Stream

To update a Drips configuration you'll need to use the NFTDriver.setDrips method:

setDrips(
    tokenId: string, 
    tokenAddress: string, 
    currentReceivers: DripsReceiverStruct[], 
    newReceivers: DripsReceiverStruct[], 
    transferToAddress: string, 
    balanceDelta?: BigNumberish)
: Promise<ContractTransaction>

Take a look at this method's documentation to understand what each parameter represents.

To use this method you will first need to create a NFTDriverClient and a DripsSubgraphClient.

You’ll also need to know the assetId of the ERC20 token you’re updating:

const assetId = Utils.Asset.getIdFromAddress(tokenAddress);

You'll need to have the list of current receivers in order to update the stream. You can get the current receivers by calling:

const currentDripsConfiguration =
    await subgraphClient.getUserAssetConfigById(configuredUserId, assetId);
const currentReceivers = currentDripsConfiguration.dripsEntries || [];

Next, you’ll need to create a list of new receivers that you want to set. Take a look at this code sample, which shows how you can do this with the help of some utility functions the SDK exposes, from some form inputs. If you would like to see this code sample in action, you can do so by running the NFTDriverClient examples app.

Finally call the setDrips method to update the Drips Configuration.
