## Background

This repo contains starter code for building [`@tableland`](https://github.com/tablelandnetwork) applications. It comes packed with packages and starter code, including:

- Tableland clients & tools—EVM contracts, SDK, Local Tableland, and Hardhat Tableland plugin.
- A `Starter` contract that imports Tableland and OpenZeppelin contract—including table creation, writes, and access control setup.
- Basic deployment script and a unit test that sets up the `TablelandTables` registry for contract interaction.
- Other useful scripts and packages for local deployment, formatting, and testing—including `prettier`, `eslint`, `solhint`, and Hardhat configuration setup.

## Usage

First, clone this repo:

```sh
git clone https://github.com/tablelandnetwork/hardhat-js-tableland-template
```

### Build & deploy

To simply compile contracts, you can install dependencies with `npm install` and then run:

```
npm run build
```

To install packages, compile contracts, and also startup Local Tableland and Hardhat nodes, run the following:

```
npm run up
```

This will keep the nodes running until you exit the session. While this is running, you can then choose to deploy the contracts to these local networks by opening a new terminal window and running:

```
npm run deploy:up
```

Alternatively, you may want to deploy contracts locally but without active nodes running. The following can be used to deploy the contracts while also starting & shutting down Local Tableland and Hardhat nodes once the script exits. Be sure anything running via `npm run up` has been closed out before running:

```
npm run deploy:local
```

Lastly, to deploy to any live network listed in `hardhat.config.js`, you can simply pass the network name after running the `deploy` command. The `.env.example` file should first be copied to a `.env` file and then have all of the values for private keys and API keys replaced. For example, to deploy contracts on Ethereum mainnet, you would do the following after creating a `.env` file with variables for `ETHEREUM_PRIVATE_KEY`, `ETHEREUM_API_KEY`, and (optionally) `ETHERSCAN_API_KEY`:

```
npm run deploy mainnet
```

Note that if no network name is passed, the script will fail.

### Testing

For full test coverage, run the following, which will show statement, branch, function, and line coverage (see `index.html` located in the `coverage` directory):

```
npm test
```

You can see gas costs associated with each contract method:

```
npm run test:gas
```

### Formatting & cleanup

Remove untracked files and directories, such as those that were autogenerated:

```
npm run clean
```

Format and lint the project:

```
npm run format
```

### Extracting the ABI and bytecode

You can grab the assets you need by compiling the contracts and then using some [`jq`](https://jqlang.github.io/jq/) magic:

#### ABI

```shell
cat artifacts/contracts/Starter.sol/Starter.json | jq '.abi' > abi.json
```

#### Bytecode

```shell
cat artifacts/contracts/Starter.sol/Starter.json | jq -r '.bytecode' > bytecode.bin
```

### Contract verification

To perform contract verification on Etherscan and other block explorers, you first need to deploy a contract to a live network, such as Sepolia:

```shell
npx hardhat run scripts/deploy.js --network sepolia
```

Then, copy the logged deployment address and replace `DEPLOYED_CONTRACT_ADDRESS` with this value in the command below:

```shell
npx hardhat verify DEPLOYED_CONTRACT_ADDRESS --network sepolia
```
