Use hardhat-laika

What is hardhat-laika ?

hardhat-laika is Laika's own Hardhat plugin that helps you sync your compiled contracts with Laika. This enables you to make a request without having to write a single line of extra code.

In counterview, it also boosts your performance when developing with Hardhat! 💪

Let’s try it out!

First, we are going to start a new Hardhat project using

npx hardhat init

Then, pick a configuration you like (We'll be usingthis configuration and Greeter.sol as an example contract in this guiding example)

✔ What do you want to do? · Create a JavaScript project
✔ Hardhat project root: · /Users/custom/Development/HARDHAT-LAIKA-TUTORIAL
✔ Do you want to add a .gitignore? (Y/n) · y
✔ Do you want to install this sample project's dependencies with npm (hardhat @nomicfoundation/hardhat-toolbox)? (Y/n) · y

After the project setup is completed, let’s install hardhat-laika by using

npm i hardhat-laika

Now, import it to your hardhat.config.js By adding a require(…) statement at the top

Alright, now we’re all set! Let’s try to use it!

There are two ways to use hardhat-laika, viz.

  1. through the command line

  2. through your own scripts (by defining a hardhat-laika task)

Let’s try the first way.

  1. The Hardhat Runner CLI

First, Let’s compile our contract so we can get the ABIs.

Then, use the laika-sync task to sync it to Laika

For this example, we'll use the command with the following parameters:

You should be able to see something like this.

laika-sync task
laika-sync task

2. Creating a Script

Let’s take a look at scripts/sample-script.js

We just have to simply add hre.run() to line 25 and we’re set! We can run it using the command.

You should be able to see something like this.

Both methods enable you to directly integrate Laika with your Hardhat environment as shown.
