Hardhat Project Setup
Install and use the Hardhat plugin
The Hardhat plugin extends Hardhat network by listening to incoming blocks and synchronizing them directly with the dashboard. Once installed and included, you won't need to run the CLI as it will be able to listen and synchronize blocks directly.
Installation
Add
hardhat-ethernal to your package.json, and run npm install or yarnSynchronize blocks & transactions
In your
hardhat-config.jsfile, require the plugin:1
require('hardhat-ethernal');
Copied!
That's it! Blocks and transactions will now be synchronized.
Options
It's possible to disable the synchronization by setting
ethernalSync to false on the hre object.You can also specify which workspace you want to synchronize blocks & transactions to (default to the last one used in the dashboard).
1
extendEnvironment((hre) => {
2
hre.ethernalSync = true;
3
hre.ethernalWorkspace = 'Workspace';
4
});
Copied!
Logging In
You can log in either by using
1
ethernal login
Copied!
Or by calling Hardhat commands with extra env variables:
1
ETHERNAL_EMAIL=[email protected] ETHERNAL_PASSWORD=yourpwd npx hardhat node
Copied!
Synchronize artifacts
Require the package in your deploy script:
1
const ethernal = require('hardhat-ethernal');
Copied!
The plugin will add an
ethernal object with a push function on the hre object.
This function takes two parameters:name: name of the contract (case sensitive). It needs to match exactly the name of the deployed contractaddress: address of the contract
You should call this function anytime after the contract has been successfully deployed.
This function returns an empty promise.
Example
1
const hre = require("hardhat");
2
const ethernal = require('hardhat-ethernal');
3
4
async function main() {
5
6
const Greeter = await hre.ethers.getContractFactory("Greeter");
7
const greeter = await Greeter.deploy("Hello, Hardhat!");
8
9
await hre.ethernal.push({
10
name: 'Greeter',
11
address: greeter.address
12
})
13
14
console.log("Greeter deployed to:", greeter.address);
15
}
16
17
main()
18
.then(() => process.exit(0))
19
.catch(error => {
20
console.error(error);
21
process.exit(1);
22
});
