## @0x/subproviders

A few useful web3 subproviders including a LedgerSubprovider useful for adding Ledger Nano S support.

We have written up a [guide](https://0x.org/docs/guides/web3-provider-explained#web3-provider-examples) article detailing some use cases of this subprovider package.

### Read the [Documentation](https://0x.org/docs/tools/subproviders).

## Installation

```
yarn add @0x/subproviders
```

If your project is in [TypeScript](https://www.typescriptlang.org/), add the following to your `tsconfig.json`:

```json
"compilerOptions": {
    "typeRoots": ["node_modules/@0x/typescript-typings/types", "node_modules/@types"],
}
```

## Contributing

We welcome improvements and fixes from the wider community! To report bugs within this package, please create an issue in this repository.

Please read our [contribution guidelines](../../CONTRIBUTING.md) before getting started.

### Install dependencies

If you don't have yarn workspaces enabled (Yarn < v1.0) - enable them:

```bash
yarn config set workspaces-experimental true
```

Then install dependencies

```bash
yarn install
```

### Build

To build this package and all other monorepo packages that it depends on, run the following from the monorepo root directory:

```bash
PKG=@0x/subproviders yarn build
```

Or continuously rebuild on change:

```bash
PKG=@0x/subproviders yarn watch
```

### Clean

```bash
yarn clean
```

### Lint

```bash
yarn lint
```

### Run tests

#### Unit tests

```bash
yarn run test:unit
```

#### Integration tests

In order to run the integration tests, make sure you have a Ledger Nano S available.

-   Setup your Ledger with the development mnemonic seed: `concert load couple harbor equip island argue ramp clarify fence smart topic`
-   Plug it into your computer
-   Unlock the device
-   Open the on-device Ethereum app
-   Make sure "browser support" and "contract data" are disabled
-   Start [TestRPC](https://github.com/trufflesuite/ganache-cli) locally at port `8545`

Then run:

```
yarn test:integration
```

**Note:** We assume a derivation path of `m/44'/60'/0'/0` which is already configured in the tests. With this setup and derivation path, your first account should be `0x5409ed021d9299bf6814279a6a1411a7e866a631`, exactly like TestRPC.

#### All tests

```bash
yarn run test:all
```
npm package: @laodabi/0x-utils
Description: 0x TS utils
Latest version: 6.5.2

## @0x/utils

Utils to be shared across 0x projects and packages

## Installation

```bash
yarn add @0x/utils
```

If your project is in [TypeScript](https://www.typescriptlang.org/), add the following to your `tsconfig.json`:

```json
"compilerOptions": {
    "typeRoots": ["node_modules/@0x/typescript-typings/types", "node_modules/@types"],
}
```

## Usage

```javascript
import { addressUtils, bigNumberConfigs, classUtils, intervalUtils, promisify } from '@0x/utils';
```

## Troubleshooting

If you are still seeing TS type errors complaining about missing DOM types such as `Response`:

```
error TS2304: Cannot find name 'Response'.
```

Then you need to explicitly add the `dom` lib to your compiler options in `tsconfig.json`. The `dom` library is included by default, but customizing the `lib` option can cause it to be dropped.

```
"compilerOptions": {
    "lib": [..., "dom"],
```
