Create a new folder and navigate to it: - -```bash -mkdir web3-providers-tutorial -cd web3-providers-tutorial -``` - -3. Install web3.js using npm: - -```bash -npm i web3 -``` - -4. Create a new JavaScript file called `web3-websocket-provider.js` in your code editor. - -5. Copy and paste the following code into your `web3-websocket-provider.js` file and save it: - -```typescript title='WebSocket Provider' -import { Web3 } from 'web3'; - -// Connect to the Ethereum network using WebSocket provider -const ganacheUrl = 'ws://localhost:8545'; -const wsProvider = new Web3.providers.WebsocketProvider(ganacheUrl); -const web3 = new Web3(wsProvider); - -async function main() { - try { - console.log('Does the provider support subscriptions?:', wsProvider.supportsSubscriptions()); - - // Subscribe to new block headers - const subscription = await web3.eth.subscribe('newBlockHeaders'); - - subscription.on('data', async (blockhead) => { - console.log('New block header: ', blockhead); - - // You do not need the next line if you like to keep being notified for every new block - await subscription.unsubscribe(); - console.log('Unsubscribed from new block headers.'); - }); - subscription.on('error', (error) => console.log('Error when subscribing to New block header: ', error)); - - // Get the list of accounts in the connected node which is in this case: Ganache. - const accounts = await web3.eth.getAccounts(); - // Send a transaction to the network - const transactionReceipt = await web3.eth.sendTransaction({ - from: accounts[0], - to: accounts[1], - value: web3.utils.toWei('0.001', 'ether'), - }); - console.log('Transaction Receipt:', transactionReceipt); - } catch (error) { - console.error(error); - } -} - -main(); -``` - -6. Ensure that Ganache is running as mentioned in the [Prerequisites](#prerequisites) section. - -7. Type `node web3-websocket-provider.js` in the command prompt or terminal window and press Enter. This will run your JavaScript file. - -If everything is set up properly, you should see the new block headers, transaction hash, and pending transaction printed in the console. The unique feature of WebSocket provider highlighted in this example is that it can subscribe to new block headers and pending transactions to get them in real-time. And by running the sample, you will get something similar to this in your console: - -```bash -Do the provider supports subscription?: true -New block header: { - logsBloom: '0x00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000', - miner: '0x0000000000000000000000000000000000000000', - difficulty: '0', - totalDifficulty: '0', - extraData: '0x', - gasLimit: 6721975, - gasUsed: 21000, - hash: '0xd315cecf3336640bcd1301930805370b7fe7528c894b931dcf8a3b1c833b68c8', - mixHash: '0x1304070fde1c7bee383f3a59da8bb94d515cbd033b2638046520fb6fb596d827', - nonce: '0x0000000000000000', - number: 40, - parentHash: '0xeb7ce3260911db2596ac843df11dbcbef302e813e1922db413f6f0b2a54d584d', - receiptsRoot: '0xf78dfb743fbd92ade140711c8bbc542b5e307f0ab7984eff35d751969fe57efa', - stateRoot: '0x95e416eec0932e725ec253779a4e28b3d014d05e41e63c3369f5da42d26d1240', - timestamp: 1684165088, - transactionsRoot: '0x8f87380cc7acfb6d10633e10f72567136492cb8301f52a41742eaca9449bb378', - sha3Uncles: '0x1dcc4de8dec75d7aab85b567b6ccd41ad312451b948a7413f0a142fd40d49347', - baseFeePerGas: 4959456, - size: undefined -} -Transaction Receipt: { - transactionHash: '0x0578672e97d072b4b91773c8bfc710e4f777616398b82b276323408e59d11362', - transactionIndex: 0n, - blockNumber: 1n, - blockHash: '0x5c05248fe0fb8f45a8c9b9600904a36c0e5c74dce01495cfc72278c185fe7838', - from: '0x6e599da0bff7a6598ac1224e4985430bf16458a4', - to: '0x6f1df96865d09d21e8f3f9a7fba3b17a11c7c53c', - cumulativeGasUsed: 21000n, - gasUsed: 21000n, - logs: [], - logsBloom: '0x00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000', - status: 1n, - effectiveGasPrice: 2000000000n, - type: 0n -} -Unsubscribed from new block headers. -```
