Getting Started with Freshmint

This guide covers how to use the Freshmint CLI tool to create and manage an NFT application on Flow.

Installation

npm install -g freshmint

⚠️ Important: Freshmint depends on the Flow CLI, so make sure you have it installed:

Create a project

Start by creating a new Freshmint project:

fresh start your-project-name

cd ./your-project-name

This command creates a new directory with the following:

  • A custom NFT contract, just for you!
  • Transactions and scripts to interact with your contract.
  • Sample NFTs and image assets (in nfts.csv and assets).
  • A pre-built Next.js web app for running a live drop.
  • A project configuration file (freshmint.yaml).
  • Flow configuration files.

Start the local dev server

Freshmint uses the Flow emulator and FCL dev wallet for rapid local development.

This command launches the emulator and dev wallet, then deploys all Cadence contracts.

Keep it running while you build!

fresh dev

Configure IPFS pinning

Freshmint uses NFT.Storage to upload and pin files to IPFS.

  1. Sign up for a free NFT.Storage account.
  2. Create a new API key in the dashboard.
  3. Add the API key to the .env file:
# .env
PINNING_SERVICE_ENDPOINT="https://nft.storage/api"
PINNING_SERVICE_KEY="Paste your NFT.Storage key here!"

Mint your NFTs

This command mints the NFTs listed in nfts.csv (or editions.csv for edition contracts).

Before minting, it also pins images and other media to IPFS.

Your project comes with a few sample NFTs, but you can edit that file to add your own! We recommend using a spreadsheet tool like Microsoft Excel, Google Sheets, Numbers for Mac or Excel Viewer for VS Code.

fresh mint

Launch the web app

Install and run the pre-built Next.js web app:

# Switch to the web app directory
cd ./web

npm install
npm run dev

Start a drop

The start-drop command creates a new drop that lists all of your minted NFTs for the same price.

Users can purchase NFTs on a first come, first served basis in the same order they were minted.

# Start a drop with a price of 42 FLOW
fresh start-drop 42.0

Stop a drop

# Stop a running drop
fresh stop-drop
