const { network } = require("hardhat")
const { networkConfig, devlopementChains } = require("../helper-hardhat-config")
module.exports = async ({ getNamedAccounts, deployments }) => {
const { deploy, log } = deployments
const { deployer } = await getNamedAccounts()
const chainId = network.config.chainId
let ethUsdPriceFeedAddress
if (devlopementChains.includes(network.name)) {
const ethUsdAggregator = await deployments.get("MockV3Aggregator")
ethUsdPriceFeedAddress = ethUsdAggregator.address
} else {
ethUsdPriceFeedAddress = networkConfig[chainId]["ethUsdPriceFeed"]
}
log("----------------------------------------------------")
log("Deploying FundMe and waiting for confirmations...")
const fundMe = await deploy("FundMe", {
from: deployer,
args: [ethUsdPriceFeedAddress],
log: true,
// we need to wait if on a live network so we can verify properly
// waitConfirmations: network.config.blockConfirmations || 1,
})
log("----------------------------------------------------")
}
module.exports.tags = ["all", "fundme"]I'm getting below error on deploy of FundMe. Please help me resolving this , I'm stuck not able to find any working solution |

If you look at that loooooong error on the first line of your error, you'll seee:
So it's likely something is wrong with either you constructor, or your
console.log(ethUsdPriceFeedAddress)Before you run your deploy function? |

I got stuck at this particular point and tried figuring it out, PatrickAlphaC indeed gave us all we need to be successful and now i understand why he emphasized so much on community, just did some googling around found |

This worked for me as well, but can someone explain why thats the case? I dont understand how the getConversionRate function being internal would effect how the ethUsdPriceFeed is being perceived. I mean I dont really see the link between a function that only takes th ethAmount and PriceFeed as inputs and another input into a network? As you can probably tell I'm very confused and would appreciate any help anyone can provide. Thank you so much in advance! |

This is a bit confusing! Let me try to break it down @mosh02. When we work with libraries, we usually use this: using x for y;like: using PriceConverter for uint256;This means that all the functions in the PriceConverter library are available to call on any This means, we can call AggregatorV3Interface feed = AggregatorV3Interface(address(0x23424252));
uint256 cat = 1;
cat.getConversionRate(address(feed));But you might be asking "hey! You can think of using a library like this as substituting the first parameter with the object that the function is being invoked on. For example: cat.getConversionRate(address(feed));Is nearly the same as calling: getConversionRate(cat, address(feed));Does that make sense? |

Oh yes that makes much more sense. but since thats the case is there any reason to make library functions anything other than internal functions? Or are there other situations where we would use libraries outside of contracts? Also thank you so much for this course its extremely helpful and you've done an amazing job on it, hope the best for you and your loved ones. |
