Web3Eth

The Web3Eth allows you to interact with an Ethereum blockchain.

For using Web3 Eth functions, first install Web3 package using npm i web3 or yarn add web3 based on your package manager usage. After that, Web3 Eth functions will be available as mentioned in following snippet.

import { Web3 } from 'web3';
const web3 = new Web3('https://mainnet.infura.io/v3/<YOURPROJID>');

const block = await web3.eth.getBlock(0);

For using individual package install web3-eth package using npm i web3-eth or yarn add web3-eth and only import required functions. This is more efficient approach for building lightweight applications.

import { Web3Eth } from 'web3-eth';

const eth = new Web3Eth('https://mainnet.infura.io/v3/<YOURPROJID>');
const block = await eth.getBlock(0);

sendTransaction

▸ sendTransaction<ReturnFormat>(transaction, returnFormat?, options?): Web3PromiEvent<TransactionReceipt, SendTransactionEvents<ReturnFormat>>

Type parameters

Name	Type
`ReturnFormat`	extends `DataFormat` = { `bytes`: `HEX` ; `number`: `BIGINT` }

Parameters

Name	Type	Description
`transaction`	`Transaction` \| `TransactionWithFromLocalWalletIndex` \| `TransactionWithToLocalWalletIndex` \| `TransactionWithFromAndToLocalWalletIndex`	The Transaction, TransactionWithFromLocalWalletIndex, TransactionWithToLocalWalletIndex or TransactionWithFromAndToLocalWalletIndex to send. Note: In the `to` and `from` fields when hex strings are used, it is assumed they are addresses, for any other form (number, string number, etc.) it is assumed they are wallet indexes.
`returnFormat`	`ReturnFormat`	(DataFormat defaults to DEFAULT_RETURN_FORMAT) Specifies how the return data should be formatted.
`options?`	`SendTransactionOptions`<`TransactionReceipt`>	A configuration object used to change the behavior of the `sendTransaction` method.

Returns

▸ subscribe<T, ReturnType>(name, args?, returnFormat?): Promise<InstanceType<RegisteredSubscription[T]>>

Lets you subscribe to specific events in the blockchain.

Type parameters

Name	Type
`T`	extends keyof `RegisteredSubscription`
`ReturnType`	extends `DataFormat` = `DataFormat`

Parameters

Name	Type	Description
`name`	`T`	The subscription you want to subscribe to.
`args?`	`ConstructorParameters`<`RegisteredSubscription`[`T`]>[`0`]	Optional additional parameters, depending on the subscription type.
`returnFormat`	`ReturnType`	-

Returns

Promise<InstanceType<RegisteredSubscription[T]>>

A subscription object of type RegisteredSubscription. The object contains:

subscription.id: The subscription id, used to identify and unsubscribing the subscription.
subscription.subscribe(): Can be used to re-subscribe with the same parameters.
subscription.unsubscribe(): Unsubscribes the subscription and returns TRUE in the callback if successful.
subscription.args: The subscription arguments, used when re-subscribing.

You can use the subscription object to listen on:

on("data") - Fires on each incoming log with the log object as argument.
on("changed") - Fires on each log which was removed from the blockchain. The log will have the additional property "removed: true".
on("error") - Fires when an error in the subscription occurs.
on("connected") - Fires once after the subscription successfully connected. Returns the subscription id.

Example

// Subscribe to `logs`
const logSubscription = web3.eth.subscribe('logs', {
    address: '0x1234567890123456789012345678901234567890',
    topics: ['0x033456732123ffff2342342dd12342434324234234fd234fd23fd4f23d4234']
});
logSubscription.on('data', (data: any) => console.log(data));
logSubscription.on('error', (error: any) => console.log(error));

Example

// Subscribe to `newBlockHeaders`
const newBlocksSubscription = await web3.eth.subscribe('newBlockHeaders');

newBlocksSubscription.on('data', async blockhead => {
	console.log('New block header: ', blockhead);

	// You do not need the next line, if you like to keep notified for every new block
	await newBlocksSubscription.unsubscribe();
	console.log('Unsubscribed from new block headers.');
});
newBlocksSubscription.on('error', error =>
	console.log('Error when subscribing to New block header: ', error),
);

subscribe('pendingTransactions')

Subscribes to incoming pending transactions. You can subscribe to pending transactions by calling web3.eth.subscribe('pendingTransactions').

(await web3.eth.subscribe('pendingTransactions')).on('data', console.log);

subscribe('newHeads')

( same as subscribe('newBlockHeaders')) Subscribes to incoming block headers. This can be used as timer to check for changes on the blockchain.

The structure of a returned block header is BlockHeaderOutput:

(await web3.eth.subscribe('newHeads')).on( // 'newBlockHeaders' would work as well
 'data',
console.log
);

subscribe('syncing')

Subscribe to syncing events. This will return true when the node is syncing and when it’s finished syncing will return false, for the changed event.

(await web3.eth.subscribe('syncing')).on('changed', console.log);
> `true` // when syncing

(await web3.eth.subscribe('syncing')).on('data', console.log);

  }

subscribe('logs', options)

Subscribes to incoming logs, filtered by the given options. If a valid numerical fromBlock options property is set, web3.js will retrieve logs beginning from this point, backfilling the response as necessary.

options: You can subscribe to logs matching a given filter object, which can take the following parameters:

fromBlock: (optional, default: 'latest') Integer block number, or 'latest' for the last mined block or 'pending', 'earliest' for not yet mined transactions.
address: (optional) Contract address or a list of addresses from which logs should originate.
topics: (optional) Array of 32 Bytes DATA topics. Topics are order-dependent. Each topic can also be an array of DATA with or options.

 (await web3.eth.subscribe('logs', {
   address: '0xdac17f958d2ee523a2206206994597c13d831ec7',
  })).on('data', console.log);
