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.

npx hardhat compile

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

npx hardhat laika-sync --contract <contract_name> --address <OPTIONAL address_of_that_contract>

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

npx hardhat laika-sync --contract Lock --address 0x5FbDB2315678afecb367f032d93F642f64180aa3

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.

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

You should be able to see something like this.

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