Cannot find 'block' and 'sender' on Minting a new Position

[z0st]

Hi there, I want to ask about the 'block' and 'sender' names when I run the code that appear on https://docs.uniswap.org/sdk/guides/liquidity/minting.

const deadline = block.timestamp + 200

const { calldata, value } = NonfungiblePositionManager.addCallParameters(position, {
  slippageTolerance: new Percent(50, 10_000),
  recipient: sender,
  deadline: deadline,
})

I Googled about 'block.timestamp' and just found something about Web3JS package for node but it doesn't work too. And the same with the name 'sender'.

I have installed: ethers @uniswap/v3-sdk @uniswap/sdk-core Web3

I'm using node 16.15.0,

Thanks in advance, Alex

Hey @z0st! The deadline is a flexible parameter, that just ensures the liquidity addition transaction only occurs before the given UNIX timestamp. If you specifically want to get the latest block timestamp, one option is to use ethers.js as seen here https://docs.ethers.io/v5/api/providers/provider/#Provider-getBlock. Otherwise, you can just set it to a timestamp in the future that you want to keep the transaction valid for.
