## Installation

Pick the build that matches your environment.

### Node.js / Bundlers

Full TypeScript typings included, works out-of-the-box with ts-node and standard bundlers.

```shell
npm install @hdwallet/core
```

### Browser (no build step)

The bundled library is available in the `./dist/` folder in this repo.

#### ESM

Modern module build, `import …` straight in the browser or any ESM-aware bundler.

```html
<script type="module">
  import { hdwallet } from './dist/hdwallet.min.js';
</script>
```

#### UDM

Standalone browser build, load via `<script>` and access as `window.hdwallet`.

```html
<script src="./dist/hdwallet.udm.min.js" type="text/javascript"></script>
```

## Quick Usage

### Example

A simple Bitcoin HDWallet generator:

```node
// SPDX-License-Identifier: MIT

import { HDWallet } from '@hdwallet/core';
import { BIP39_ENTROPY_STRENGTHS, BIP39Entropy } from '@hdwallet/core/entropies';
import { BIP39_MNEMONIC_LANGUAGES } from '@hdwallet/core/mnemonics';
import { Bitcoin as Cryptocurrency } from '@hdwallet/core/cryptocurrencies';
import { CustomDerivation } from '@hdwallet/core/derivations';
import { PUBLIC_KEY_TYPES } from '@hdwallet/core/consts';
import { BIP32HD } from '@hdwallet/core/hds';

const hdwallet: HDWallet = new HDWallet(
  Cryptocurrency, {
    hd: BIP32HD,
    network: Cryptocurrency.NETWORKS.MAINNET,
    language: BIP39_MNEMONIC_LANGUAGES.KOREAN,
    publicKeyType: PUBLIC_KEY_TYPES.COMPRESSED,
    passphrase: 'talonlab'
  }
).fromEntropy(
  new BIP39Entropy(
    BIP39Entropy.generate(
      BIP39_ENTROPY_STRENGTHS.ONE_HUNDRED_TWENTY_EIGHT
    )
  )
).fromDerivation(
  new CustomDerivation({
    path: 'm/0\'/0/0-1'  // Cryptocurrency.DEFAULT_PATH
  })
);

// console.log(JSON.stringify(hdwallet.getDump(['indexes']), null, 4));
console.log(JSON.stringify(hdwallet.getDumps(['indexes']), null, 4));
