What is @emurgo/cardano-serialization-lib-browser?

@emurgo/cardano-serialization-lib-browser is a JavaScript library designed for use in browser environments to interact with the Cardano blockchain. It provides functionalities for creating, signing, and managing Cardano transactions, addresses, and keys.

What are @emurgo/cardano-serialization-lib-browser's main functionalities?

Creating and Managing Cardano Addresses

This feature allows users to create and manage Cardano addresses. The code sample demonstrates how to create an address object from a Bech32 string and convert it back to a Bech32 string.

const { Address } = require('@emurgo/cardano-serialization-lib-browser');
const address = Address.from_bech32('addr1...');
console.log(address.to_bech32());

Building Transactions

This feature allows users to build Cardano transactions. The code sample shows how to create a transaction builder, define an output with an address and value, and add it to the transaction.

const { TransactionBuilder, TransactionOutput, Address, Value } = require('@emurgo/cardano-serialization-lib-browser');
const txBuilder = TransactionBuilder.new();
const address = Address.from_bech32('addr1...');
const output = TransactionOutput.new(address, Value.new(1000));
txBuilder.add_output(output);

Signing Transactions

This feature allows users to sign Cardano transactions. The code sample demonstrates how to create a transaction, generate a witness set, and sign the transaction using a private key.

const { Transaction, TransactionWitnessSet, Vkeywitnesses, Vkeywitness, PrivateKey } = require('@emurgo/cardano-serialization-lib-browser');
const tx = Transaction.new();
const witnessSet = TransactionWitnessSet.new();
const privateKey = PrivateKey.from_bech32('ed25519_sk...');
const vkeyWitness = Vkeywitness.new(privateKey.to_public(), privateKey.sign(tx.body()));
witnessSet.set_vkeys(Vkeywitnesses.new().add(vkeyWitness));

cardano-wallet-js

cardano-wallet-js is a JavaScript library for interacting with the Cardano blockchain, focusing on wallet functionalities. It provides a higher-level abstraction compared to @emurgo/cardano-serialization-lib-browser, making it easier to use for wallet operations but less flexible for custom transaction building.

cardano-serialization-lib

cardano-serialization-lib is the Node.js counterpart of @emurgo/cardano-serialization-lib-browser. It offers similar functionalities but is designed for server-side applications rather than browser environments.

NPM packages with GC support

Note: This package uses weak references flag from wasm-bindgen. It uses FinalizationRegistry under the hood to automatically call "free" for each CSL struct when it is no longer needed. However, use this feature with caution as it may have unpredictable behaviors.
