pnpm 9.5 Introduces Catalogs: Shareable Dependency Version Specifiers
pnpm 9.5 introduces a Catalogs feature, enabling shareable dependency version specifiers, reducing merge conflicts and improving support for monorepos.

npm install @scure/bip39
Or
yarn add @scure/bip39
import * as bip39 from '@scure/bip39';
import { wordlist } from '@scure/bip39/wordlists/english';
// Generate x random words. Uses Cryptographically-Secure Random Number Generator.
const mn = bip39.generateMnemonic(wordlist);
console.log(mn);
// Reversible: Converts mnemonic string to raw entropy in form of byte array.
const ent = bip39.mnemonicToEntropy(mn, wordlist)
// Reversible: Converts raw entropy in form of byte array to mnemonic string.
bip39.entropyToMnemonic(ent, wordlist);
// Validates mnemonic for being 12-24 words contained in `wordlist`.
bip39.validateMnemonic(mn, wordlist);
// Irreversible: Uses KDF to derive 64 bytes of key data from mnemonic + optional password.
await bip39.mnemonicToSeed(mn, 'password');
bip39.mnemonicToSeedSync(mn, 'password');
This submodule contains the word lists defined by BIP39 for Czech, English, French, Italian, Japanese, Korean, Simplified and Traditional Chinese, and Spanish. These are not imported by default, as that would increase bundle sizes too much. Instead, you should import and use them explicitly.
function generateMnemonic(wordlist: string[], strength?: number): string;
function mnemonicToEntropy(mnemonic: string, wordlist: string[]): Uint8Array;
function entropyToMnemonic(entropy: Uint8Array, wordlist: string[]): string;
function validateMnemonic(mnemonic: string, wordlist: string[]): boolean;
function mnemonicToSeed(mnemonic: string, passphrase?: string): Promise<Uint8Array>;
function mnemonicToSeedSync(mnemonic: string, passphrase?: string): Uint8Array;
All wordlists:
import { wordlist as czech } from '@scure/bip39/wordlists/czech';
import { wordlist as english } from '@scure/bip39/wordlists/english';
import { wordlist as french } from '@scure/bip39/wordlists/french';
import { wordlist as italian } from '@scure/bip39/wordlists/italian';
import { wordlist as japanese } from '@scure/bip39/wordlists/japanese';
import { wordlist as korean } from '@scure/bip39/wordlists/korean';
import { wordlist as simp } from '@scure/bip39/wordlists/simplified-chinese';
import { wordlist as spanish } from '@scure/bip39/wordlists/spanish';
import { wordlist as trad } from '@scure/bip39/wordlists/traditional-chinese';
