Hardhat plugin

A Hardhat plugin for Local Tableland and Hardhat nodes.

If you are developing with Hardhat, the @tableland/hardhat plugin can be used to run alongside Local Tableland. It's important to node that embedded in the Local Tableland process is two steps: spinning up a Tableland validator node and a Hardhat node. Thus, the plugin helps manage these and allows you to use familiar Hardhat commands.

1. Installation & setup

Create a folder and then cd into it to set up a Hardhat app. Follow the starter steps by choosing a project type (JavaScript, TypeScript, or empty) and other configurations.

npx hardhat

Then, install @tableland/hardhat as a dev dependency:

npm install --save-dev @tableland/hardhat

2. Adjust the Hardhat config & script

With @tableland/hardhat, you should import the plugin in your hardhat.config.js and adjust the config. Add the localTableland key with values silent and verbose to false—these control logging behavior.


/** @type import('hardhat/config').HardhatUserConfig */
module.exports = {
solidity: "0.8.18",
localTableland: {
silent: false,
verbose: false,

3. Start a node & deploy locally

Start a Hardhat and Local Tableland node at the same time with:

npx hardhat node --network local-tableland

Now that nodes are running, you can deploy your contract. The deployed contracts will interact with the Hardhat node, and then the Local Tableland node will materialize emitted SQL events and allow for read queries at the HTTPS gateway at http://localhost:8080/api/v1/.

Run the following in another terminal window to deploy your contract:

npx hardhat run scripts/deploy.js --network localhost

If, instead, you want to simply start up the nodes, deploy your contracts, and then shutdown the nodes (i.e., don't keep them running), you can choose to run the deploy script with local-tableland as the network. This means that you should not run the typical npx hardhat node command since there will be a port clash.

npx hardhat run scripts/deploy.js --network local-tableland
