local-node-info

I wrote a code that's working fine locally, but doesn't pass the test, I tried with "web3" package and "ethers" package, here's my code:

<!DOCTYPE html>
<body>
    <h1>NETWORK INFOS</h1>
  <h2>Chain ID: <span id="chainId"></span></h2>
  <h2>Number of blocks : <span id="blockNumber"></span></h2>

  <script src="https://cdn.ethers.io/scripts/ethers-v4.min.js"
        charset="utf-8"
        type="text/javascript">
  </script>
  <script type="text/javascript">
    document.addEventListener('DOMContentLoaded', async () => {
      try {
        // Connect to a local Ethereum node
        const provider = new ethers.providers.JsonRpcProvider('http://localhost:8545');

        // Get the chain ID
        const chainId = await provider.getNetwork().then(network => network.chainId);

        // Get the block number
        //let blockNumber = 0;
        const blockNumber = await provider.getBlockNumber();

        // Display information on the page
        document.getElementById('chainId').textContent = chainId;
        document.getElementById('blockNumber').textContent = blockNumber;
      } catch (error) {
        console.error('Error:', error.message);
      }
    });
  </script>
</body>
</html>

and here's the test response:
[1m�[43m�[30m
Puppeteer old Headless deprecation warning:�[0m�[33m
In the near feature headless: true will default to the new Headless mode
for Chrome instead of the old Headless implementation. For more
information, please see https://developer.chrome.com/articles/new-headless/.
Consider opting in early by passing headless: "new" to puppeteer.launch()

Hi @MalekLahbib, I have tried to run your solution locally, and it does not work for me :) I might have tried an incomplete version: could you please send me the full solution text using this formatting?

@nprimo thanks for the formatting advice, I didn't give attention to it, from now I will, I updated my comment so now you have the full code. I launched a local eth node with "npx hardhat node", and when I open my html file it works.

Hello @MalekLahbib,

Thank you for submitting this issue.

  • Your page is correct. However, the test environment does not have access to the internet for security reasons, which is why your library import fails. You can download the library, add it to your repository, and import it locally. I've updated the instructions for clarity.
  • The warning issue is harmless, but I've submitted a PR to remove it.
