## Dependencies

- [Node and Yarn](https://github.com/nvm-sh/nvm#installing-and-updating)
- [Docker Compose](https://docs.docker.com/compose/install)
- [Rust](https://www.rust-lang.org/tools/install)
- [Solana](https://docs.solana.com/cli/install-solana-cli-tools)
- [Anchor](https://project-serum.github.io/anchor/getting-started/installation.html#install-anchor)

## Setup

```
yarn install
yarn workspaces run build
yarn workspace @switchboard-xyz/switchboardv2-cli link
anchor build && node ./scripts/setup-example-programs.js
```

### Localnet Testing Setup

The SDK supports copying a Switchboard devnet environment to your localnet environment for integration testing. This is useful if you want to see how your program will react to Switchboard data feed updates.

First, set the _[provider.cluster]_ in `Anchor.toml` to localnet.

Next, create a Switchboard devnet queue and oracle.

```
sbv2 localnet:env --keypair ../payer-keypair.json -o .switchboard
```

This command will output:

- **start-local-validator.sh**: starts a local Solana validator with the Switchboard program, IDL, and our devnet environment pre-loaded
- **start-oracle.sh**: start a Switchboard oracle and start heartbeating on the localnet queue
- **docker-compose.yml**: docker file with the Switchboard oracle environment
- **switchboard.env**: contains your Switchboard accounts

In three separate shells, run the following commands in this order:

- `./.switchboard/start-local-validator.sh`
- `./.switchboard/start-oracle.sh`
- `anchor test --skip-local-validator`

The anchor test are configured to first fetch the account info for the Switchboard DAO controlled devnet permissionless queue. If the account info is not found, it assumes a localnet connection and looks for the `switchboard.env` with your Switchboard environment specific public keys. If a`.switchboard` directory or `switchboard.env` file is not found in the root project directory, it will look 2 levels higher until giving up.
