  • CLI private key separation for security
  • Flow.json loading for contract placeholders
  • Authentication
  • CDC file loader
  • Custom hooks
  • Deployment

Featues TODO

  • Mainnet deployment
  • JS Testing

Running the App

First run:

npm install

Local with Flow Dev, the Emulator, and Dev Wallet

Run the following to run Flow Dev, the Emulator, and Dev Wallet:

npm run dev:local

Note: Flow Dev will will automatically create new accounts and deploy for you while developing. Your flow.json will be updated automatically. Committing these changes for local development is unncessary.

Testnet

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 [name].pkey file (make sure this is gitignored) and add your account to flow.json.

Then in flow.json, add the contracts you'd like to be deployed to testnet under 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 while seeing the diff between deployed contracts and updates being pushed, you can run:

npm run dev:testnet:update
