This project is a simple script that reads eth client data and presents the current gas environment in realtime. I built this because etherscan and other websites struggle to offer a realtime view with enough context besides recommendations on what gas prices to use.
The first step is to install geth: https://geth.ethereum.org/docs/install-and-build/installing-geth
Once you have that on your system, I highly recommend spinning up a light client as it's much quicker to operate and provides the necessary data
geth --syncmode "light" --ws
The --ws flag tells geth to offer a websocket endpoint, which we need in order to get a realtime data feed of new block headers being sent around the network.
Then, while the light client is running:
- clone this repo
- Enter into it
node index.js
You should be up and running. The default websocket address should be ws://127.0.0.1:8546. You can see it print out in the geth console. If it's something different, update the address in index.js.
