This is a scaffold for an FCL NextJS Dapp on the Flow Blockchain.
- FCL setup and configuration
- Wallet Discovery (including Dev Wallet on Emulator)
- CLI private key separation for security
- Flow.json loading for contract placeholders
- Authentication
- CDC file loader
- Custom hooks
- Deployment
- Mainnet deployment
- JS Testing
First run:
npm install
In one terminal, run emulator:
flow emulator start
Then, in another terminal, run Dev Wallet:
flow dev-wallet
npm run dev:local:deploy
If you haven't yet created a testnet account, in the CLI run:
flow accounts create
Follow the steps and select testnet. This will create a testnet-account.private.json
file.
Then in flow.json
, add your testnet address prefixed with an 0x
as an alias for testnet
just like emulator
.
You'll also need to add your new testnet account to your flow.json:
// Inside of "accounts"
"testnet-account": {
"fromFile": "./testnet-account.private.json"
}
And add a deployment for this account:
// Inside of "deployments"
"testnet": {
"testnet-account": [
"HelloWorld"
]
}
Then run:
npm run dev:testnet:deploy
Whenever you need to redeploy changed contracts to Testnet, you can run:
npm run dev:testnet:update
