# Local Node Info
|
||
|
|
|
||
|
|
To start, we will create a simple page that displays basic information from our local node.
|
||
|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
Create a web page, `localNodeInfo.html` that loads an ethereum library, connects to a local node at `http://localhost:8545` and displays basic information :
|
||
|
|
|
||
|
|
- In an element with (`id`=`chainId`), the number ID of the current network
|
||
|
|
- In an element with `blockNumber` as `id` the number of blocks in the chain
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
### Hint
|
||
|
|
|
||
|
|
You can use any library such as `ethers.js` or `web3.js` to connect to your local node.
|
||
|
|
|
||
|
|
Automated tests check for elements with specific IDs, the design is up to you.
|
||
|
|
|
||
|
|
Minimal structure:
|
||
|
|
|
||
|
|
```HTML
|
||
|
|
<!DOCTYPE html>
|
||
|
|
<body>
|
||
|
|
<span id="chainId"></span>
|
||
|
|
<span id="blockNumber"></span>
|
||
|
|
|
||
|
|
<script src="XXX"></script>
|
||
|
|
<script type="module">
|
||
|
|
// Your code
|
||
|
|
</script>
|
||
|
|
</body>
|
||
|
|
</html>
|
||
|
|
```
|
||
|
|
|
||
|
