## Developing locally

```sh
# Clone repository
git clone git@github.com:renproject/ren-js.git && cd ren-js

# Install dependencies
yarn

# Build every package
yarn run build
```

## Linking

If you want to use your local version of RenJS in another repository, run

```sh
# In the ren-js repository
yarn run link:all
```

You can now link it to any other local repository by running:

```sh
# In other local repositories
yarn link @renproject/ren @renproject/chains @renproject/utils @renproject/provider
```

## Running tests

You'll need to:

1. Generate a mnemonic and send ETH (goerli for testnet) (path: `m/44'/60'/0'/0/`).
    - `let w = require("ethers").Wallet.createRandom(); console.debug(w.address, w.mnemonic.phrase);`
2. Generate a private key and send testnet crypto funds.
    - `require("send-crypto").newPrivateKey();`
3. Optionally generate an [Infura](https://infura.io) API key.

Create a `.env` file which contains the following exported variables:

```sh
export MNEMONIC="your mnemonic here"
export TESTNET_PRIVATE_KEY="your bitcoin private key"

# Optional
export INFURA_KEY="your infura key"
```

To run the tests:

```sh
yarn run test
```
