This project demonstrates a basic Hardhat use case with a HTML front-end. This was done as part of the Free Code Camp Blockchain course on YouTube.
⌨️ (12:32:57) Lesson 8: HTML / Javascript Fund Me (Full Stack / Front End)
This is a minimalistic example what you can find in the metamask docs.
- git
- You'll know you've installed it right if you can run:
git --version
- You'll know you've installed it right if you can run:
- Metamask
- This is a browser extension that lets you interact with the blockchain.
- Nodejs
- You'll know you've installed nodejs right if you can run:
node --version
And get an ouput like:vx.x.x
- You'll know you've installed nodejs right if you can run:
- Yarn instead of
npm
- You'll know you've installed yarn right if you can run:
yarn --version
And get an output like:x.x.x
- You might need to install it with npm
- You'll know you've installed yarn right if you can run:
- Clone the repo
git clone https://github.com/KwasiKK/hardhat-fundme-fcc
cd html-fund-me-fcc
- Run the file.
You can usually just double click the file to "run it in the browser". Or you can right click the file in your VSCode and run "open with live server".
Optionally:
If you'd like to run with prettier formatting, or don't have a way to run your file in the browser, run:
yarn
yarn http-server
And you should see a small button that says "connect".
Hit it, and you should see metamask pop up.
If you want to execute a transaction follow this:
Make sure you have the following installed:
- You'll need to open up a second terminal and run:
git clone https://github.com/KwasiKK/hardhat-fundme-fcc
cd hardhat-fund-me-fcc
yarn
yarn hardhat node
This will deploy a sample contract and start a local hardhat blockchain.
- Update your
constants.js
with the new contract address.
In your constants.js
file, update the variable contractAddress
with the address of the deployed "FundMe" contract. You'll see it near the top of the hardhat output.
- Connect your metamask to your local hardhat blockchain.
PLEASE USE A METAMASK ACCOUNT THAT ISNT ASSOCIATED WITH ANY REAL MONEY.
In the output of the above command, take one of the private key accounts and import it into your metamask.
Additionally, add your localhost with chainid 31337 to your metamask.
- Reserve the front end with
yarn http-server
, input an amount in the text box, and hitfund
button after connecting
