Ethereum Boilerplate Questions

hi, I compiled the code with the log(error) but I got no message back, or I just can’t find it.

  useEffect(() => {
    if (data?.result) {
      const NFTs = data.result;
      setTotalNFTs(data.total);
      for (let NFT of NFTs) {
        if (NFT?.metadata) {
          NFT.metadata = JSON.parse(NFT.metadata);
          // metadata is a string type
          NFT.image = resolveLink(NFT.metadata?.image);
          console.log(error);
        }
      }
      setNFTTokenIds(NFTs);
    }

Where should I look?
btw the nfts’s in /myBalance are showing up properly

To add to this, as it’s all react, I went to look at the vanilla JS boilerplate link from the docs but it’s not the same kind of “boilerplate” as this. In that, it’s not really anything at all…

The boilerplate was designed to be like a LEGO, so you can easily get one of the components and use it in any place of your project. There may be some imports with dependencies, but they are easy to move as well.

I actually don’t know how does it work with other stacks, you need to keep in mind that it’s a boilerplate for React.

Please give us some more info, I actually don’t understand your issue :sweat_smile:

sorry, i’m kind of a beginner with this.

So I used the last boillerplate and updated all the dependencies. Then I’m following the tutorial (filled in the .env) and got stuck at the part where the cryptopunk nfts have to show up in the browser. In the console I got only some warnings back. The nft’s in my wallet are showing up properly on the /NFTBalance page.

This is my code:

import { useMoralis } from "react-moralis";
import { useEffect, useState } from "react";
import { useMoralisWeb3Api, useMoralisWeb3ApiCall } from "react-moralis";
import { useIPFS } from "./useIPFS";

export const useNFTTokenIds = () => {
  const { token } = useMoralisWeb3Api();
  const { chainId } = useMoralis();
  const { resolveLink } = useIPFS();
  const [NFTTokenIds, setNFTTokenIds] = useState([]);
  const [totalNFTs, setTotalNFTs] = useState()
  
  const {
    fetch: getNFTTokenIds,
    data,
    error,
    isLoading,
  } = useMoralisWeb3ApiCall(token.getAllTokenIds, { chain: chainId, address: "0xb47e3cd837ddf8e4c57f05d70ab865de6e193bbb" });

  useEffect(() => {
    if (data?.result) {
      const NFTs = data.result;
      setTotalNFTs(data.total);
      for (let NFT of NFTs) {
        if (NFT?.metadata) {
          NFT.metadata = JSON.parse(NFT.metadata);
          // metadata is a string type
          NFT.image = resolveLink(NFT.metadata?.image);
          console.log(error);
        }
      }
     
      setNFTTokenIds(NFTs);
    }
  // eslint-disable-next-line react-hooks/exhaustive-deps
  }, [data]);
  
  return { getNFTTokenIds, NFTTokenIds, totalNFTs, error, isLoading };

Maybe this could help?

Please share the error messages. Do you have NFTs in your wallet?

The nft’s in my wallet are loading fine on the /nftBalance page.

Just on the /nftMarket the cryptopunks won’t show up.

Hey @bogdabart, there is no /nftMarket on the ethereum boilerplate, are you referring to the NFT marketplace boilerplate?

Thanks for reply. Yes, I’m doing the cloning opensea tutorial where you start with the boilerplate.

Changed these lines in the app.js

      <Menu.Item key="/nftMarket">
        <NavLink to="/nftMarket"> Marktplaats</NavLink>
      </Menu.Item>

<Route path="/nftMarket">
              <NFTTokenIds />

hi
yes it showing thank you

I cloned the eth boilerplate repo and created a new server on moralis - then linked them together using the application ID and server URL.

The eth boilerplate project is also very slow. Some UI elements are not loading as well. The fiat onramper doesn’t load at all. I switched to the local dev environment thinking it would make things faster, but the same issues reproduced on the local dev/test/mainnet networks.

Additional info:

I am creating this server from Beirut, Lebanon. Could it be that the region has something to do with this? Since the closest region to Beirut is Frankfurt.

Hi guys, can’t seem to get the DEX screen working (http://localhost:3000/1inch), the token list is blank, see image. I installed the 1-inch plugin already.

Also, how to get the Fiat on-ramp screen working? (again just blank screen currently)

Thanks.

Hey @bogdabart, I just checked the ethereum nft marketplace boilerplate and seems like you are missing these props on NFTTokenIds component

<Route path="/nftMarket">
   <NFTTokenIds inputValue={inputValue} setInputValue={setInputValue}/>
</Route>

Mysteriously started working lol. Just the Fiat on-ramp to figure out now.

Have you added your key to the plugin settings? Also please provide error message screenshots :man_mechanic:

Thanks. Where is the code for the smart contracts?

in the truffle folder

Thank you.

Now I am getting this error:
