Copied!
Or via npm then import.
1
npm install web3
Copied!
1
const Web3 = require("web3");
Copied!
Now that the library is imported a provider can be created.

const NODE_URL = "YOUR SPEEDY NODE URL HERE";
2
const provider = new Web3.providers.HttpProvider(NODE_URL);
3
const web3 = new Web3(provider);
Copied!
That's it! See the web3.js docs for more details on how to use the web3 object.

Next, create a provider and if needed a signer to sign transactions.
1
const NODE_URL = "YOUR SPEEDY NODE URL HERE";
2
const provider = new ethers.providers.JsonRpcProvider(NODE_URL);
