@tableland/hardhat

Tableland support for Hardhat projects.

What

This plugin makes it easy to run and interact with a local Tableland node for development and testing purposes. Upcoming versions will expand functionality to include support for Tableland table creation and management, plus more.

Installation

npm install @tableland/hardhat --save-dev

Import the plugin in your hardhat.config.js:

require("@tableland/hardhat");

Or if you are using TypeScript, in your hardhat.config.ts:

import "@tableland/hardhat";

Configuration

This plugin extends the HardhatUserConfig object with an optional localTableland field of type Config, which allows you to configure how local Tableland will run.

This is an example of how to set it:

const config: HardhatUserConfig = {
  ...
  localTableland: {
    silent: false,
    verbose: false,
  },
  ...
};

export default config;

Tasks

This plugin creates no additional tasks, but does add a new network called local-tablaland that can be passed to any task that supports the --network flag. For example:

npx hardhat test --network local-tableland

and:

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

and:

npx hardhat node --network local-tableland

Environment extensions

This plugin extends the Hardhat Runtime Environment by adding a localTableland field whose type is:

{
    start: (config?: Config) => Promise<void>;
    stop: () => Promise<void>;
}

These functions allow you to progamatically interact with local Tableland, in a Hardhat script, for example.

Usage

There are no additional steps you need to take for this plugin to work. Simply use the local-tableland network when running Hardhat tasks or interact with the Hardhat Runtime Environment's localTableland API programmatically.

Important note: The @nomicfoundation/hardhat-network-helpers package provides a useful function loadFixture that will reset the state of the Hardhat network to a snapshot that your fixture captured. Unfortunately, Local Tablelend can't yet deal with this type of state reset, so avoid using loadFixture when using Local Tableland.
