This repo is for a starter project using Firebase and Hardhat

Installation

1. Install hardhat and firebase

npm install --save-dev hardhat
npm install --save-dev firebase

2. Create the sample project. The sample overwrites this file, so we work around.

mv README.md README.md.bak
npx hardhat
cat README.md >> README.md.bak
mv README.md.bak README.md

Use the JavaScript option.

3. Initialize firebase

firebase init

In the first menu, at minimum you'll want to select:

• Hosting: Configure files for Firebase Hosting...
• Emulators: Set up local emulators for Firebase products

In the project setup menu, either create a new project or use an existing one.

In the emulators menu, at minimum you'll want to select:

• Hosting Emulator

Other options can be safely left as defaults. If you need to update anything later, re-run firebase init.

4. Install Hardhat dependencies

npm install --save-dev @openzeppelin/hardhat-upgrades
npm install --save-dev @openzeppelin/contracts
npm install --save-dev @nomiclabs/hardhat-ethers ethers

Running locally

You'll need a few separate shells.

1. In shell 1, run a local node on all network interfaces.

npm run hh:node

2. In shell 2, run firebase

npm run fb:start

Verify that you can connect to the local firebase server in your browser at http://localhost:5000.

3. In shell 3, deploy to the hardhad project to the local node

npm run hh:deploy

Sample Hardhat Project

This project demonstrates a basic Hardhat use case. It comes with a sample contract, a test for that contract, and a script that deploys that contract.

Try running some of the following tasks:

npx hardhat help
npx hardhat test
REPORT_GAS=true npx hardhat test
npx hardhat node
npx hardhat run scripts/deploy.js
