2. Frontend w/ moralis

a. NextJs setup ✅ b. Home Page: b.1.1. Moralis setUp ✅ b.1.1.2. Moralis event sync b.1. Show recently listed NFT b.b.1. If you own the NFT, you can update the listing b.b.2. If not, you can buy

c. Sell Page: c.1. You can list your NFT on the marketplace.

Full-Stack Setup

1. Git clone the contracts repo

In it's own terminal / command line, run:

git clone https://github.com/PatrickAlphaC/hardhat-nft-marketplace-fcc
cd hardhat-nextjs-nft-marketplace-fcc
yarn

2. Start your node

After installing dependencies, start a node on it's own terminal with:

yarn hardhat node

3. Connect your codebase to your moralis server

Setup your event moralis. You'll need a new moralis server to get started.

Sign up for a free account here.

Once setup, update / create your .env file. You can use .env.example as a boilerplate.

NEXT_PUBLIC_APP_ID=XXXX
NEXT_PUBLIC_SERVER_URL=XXXX
moralisApiKey=XXX
moralisSubdomain=XXX
masterKey=XXX
chainId=31337

With the values from your account.

Then, in your ./package.json update the following lines:

"moralis:sync": "moralis-admin-cli connect-local-devchain --chain hardhat --moralisSubdomain XXX.usemoralis.com --frpcPath ./frp/frpc",
"moralis:cloud": "moralis-admin-cli watch-cloud-folder  --moralisSubdomain XXX.usemoralis.com --autoSave 1 --moralisCloudfolder ./cloudFunctions",
"moralis:logs": "moralis-admin-cli get-logs --moralisSubdomain XXX.usemoralis.com"

Replace the XXX.usemoralis.com with your subdomain, like 4444acatycat.usemoralis.com and update the moralis:sync script's path to your instance of frp (downloaded as part of the Moralis "Devchain Proxy Server" instructions mentioned above)

4. Globally install the moralis-admin-cli

yarn global add moralis-admin-cli

5. Setup your Moralis reverse proxy

Optionally: On your server, click on "View Details" and then "Devchain Proxy Server" and follow the instructions. You'll want to use the hardhat connection.

  • Download the latest reverse proxy code from FRP and add the binary to ./frp/frpc.
  • Replace your content in frpc.ini, based on your devchain. You can find the information on the DevChain Proxy Server tab of your moralis server.

In some Windows Versions, FRP could be blocked by firewall, just use a older release, for example frp_0.34.3_windows_386

Mac / Windows Troubleshooting: https://docs.moralis.io/faq#frpc

Once you've got all this, you can run:

yarn moralis:sync

You'll know you've done it right when you can see a green connected button after hitting the refresh symbol next to DISCONNECTED. You'll want to keep this connection running.

Connected to Moralis Reverse Proxy

IMPORTANT

Anytime you reset your hardhat node, you'll need to press the RESET LOCAL CHAIN button on your UI!

6. Setup your Cloud functions

In a separate terminal (you'll have a few up throughout these steps)

Run yarn moralis:cloud in one terminal, and run yarm moralis:logs in another. If you don't have moralis-admin-cli installed already, install it globally with yarn global add moralis-admin-cli.

Note: You can stop these after running them once if your server is at max CPU capactity. If you hit the little down arrow in your server, then hit Cloud Functions you should see text in there.

Cloud Functions Up

Cloud Functions Up

Make sure you've run yarn moralis:sync from the previous step to connect your local Hardhat devchain with your Moralis instance. You'll need these 3 moralis commands running at the same time.

7. Add your event listeners

You can do this programatically by running:

node watchEvents.js

Or, if you want to do it manually

Finally, go to View Details -> Sync and hit Add New Sync -> Sync and Watch Contract Events

Add all 3 events by adding it's information, like so:

  1. ItemListed:
    1. Description: ItemListed
    2. Sync_historical: True
    3. Topic: ItemListed(address,address,uint256,uint256)
    4. Abi:
{
  "anonymous": false,
  "inputs": [
    {
      "indexed": true,
      "internalType": "address",
      "name": "seller",
      "type": "address"
    },
    {
      "indexed": true,
      "internalType": "address",
      "name": "nftAddress",
      "type": "address"
    },
    {
      "indexed": true,
      "internalType": "uint256",
      "name": "tokenId",
      "type": "uint256"
    },
    {
      "indexed": false,
      "internalType": "uint256",
      "name": "price",
      "type": "uint256"
    }
  ],
  "name": "ItemListed",
  "type": "event"
}

5. Address: <YOUR_NFT_MARKETPLACE_DEPLOYED_ADDRESS_FROM_HARDHAT>
6. TableName: ItemListed

You can add the canceled and bought events later.

8. Mint and List your NFT

Back in the main directory, run:

yarn hardhat run scripts/mint-and-list-item.js --network localhost

And you'll now have an NFT listed on your marketplace.

9. Start your front end

At this point, you'll have a few terminals running:

  • Your Hardhat Node
  • Your Hardhat Node syncing with your moralis server
  • Your Cloud Functions syncing
  • Your Moralis Logging

And you're about to have one more for your front end.

yarn run dev

And you'll have your front end, indexing service running, and blockchain running.

Minimal Quickstart

  1. Clone the backend repo
git clone https://github.com/PatrickAlphaC/hardhat-nft-marketplace-fcc
cd hardhat-nextjs-nft-marketplace-fcc
yarn
yarn hardhat node

Leave that terminal running^

  1. Clone the frontend
git clone https://github.com/PatrickAlphaC/nextjs-nft-marketplace-moralis-fcc
cd nextjs-nft-marketplace-moralis-fcc
yarn

Setup your .env with moralis info and update your package.json with moralis subdomain.

  1. Sync your hardhat node with moralis

Update your frpc.ini file with what you see in the moralis UI.

Leave this terminal running:

yarn moralis:sync
  1. Watch for events && Update cloud functions

Run once:

yarn moralis:cloud

node watchEvents.js
  1. Emit an event

Back in your hardhat project, run:

yarn hardhat run scripts/mint-and-list-item.js --network localhost

And you should see it updated in the database
