  }'

JavaScript (web3.js)

const { Connection } = require('@solana/web3.js');

const connection = new Connection("http://cute-rabbit.by.supanode.xyz:8899/", 'confirmed');

(async () => {
    const slot = await connection.getSlot();
    console.log("Current Slot:", slot);
})();

Supported Methods

The full Solana JSON-RPC API is supported. Some heavy methods like getProgramAccounts can be slow on shared tiers — if you rely on them heavily, consider a higher tier or a dedicated node.
