Requirements¶

The NFT Box has the following requirements:

Node.js 10.x or later
NPM version 5.2 or later
Windows, Linux or MacOS

Helpful, but optional: - An Infura account and Project ID - A MetaMask account

Setup¶

Installation¶

First ensure you are in a new and empty directory.

Run the unbox command via npx and skip to step 3. This will install all necessary dependencies. A Create-React-App is generated in the client directory.
```
npx truffle unbox nft-box
```
Alternatively, you can install Truffle globally and run the unbox command.
```
npm install -g truffle
truffle unbox nft-box
```
In the root directory install the required dependices. This will install a few things along with Open Zeppelin Contracts check them out here for more info. javascript npm install @openzeppelin/contracts
Add the contructor arguments to deployer function in 2_deploy_contracts.js. The URI for your NFT images must be passed as the first argument. The name and symbol of the token will be passed as the second and third respectively. ```javascript module.exports = function(deployer) { deployer.deploy(NFTCollection,"YOUR URI","TOKEN NAME","TOKEN SYMBOL"); }; ``````
In the root directory install the required dependices. This will install a few things along with Open Zeppelin Contracts check them out here for more info. javascript npm install
Run the development console.
```
truffle develop
```
Compile and migrate the smart contracts. Note inside the development console we don't preface commands with truffle. ```javascript compile migrate
In the client directory, we run the React app. Smart contract changes must be manually recompiled and migrated.
```
// in another terminal (i.e. not in the truffle develop prompt)
cd client
npm install
npm run start
```
After migrating your contracts head to the client directory and run npm run start to view the application in your http://localhost:3000/. Connect your wallet and mint your first NFT!
You can check the developer console to see the transaction has and if you deploy to rinkeby you will be able to see the NFT on their test-net site here.
To build the application for production, use the build script. A production build will be in the client/build folder.
```
// ensure you are inside the client directory when running this
npm run build
```

Deployment¶

To deploy your contracts to a public network (such as a testnet or mainnet) there are two approaches. The first uses Truffle Dashboard which provides "an easy way to use your existing MetaMask wallet for your deployments". The second, requires copying your private key or mnemonic into your project so the deployment transactions can be signed prior to submission to the network.

Using Truffle Dashboard (recommended)¶

Truffle Dashboard ships with Truffle and can be started with truffle dashboard. This in turn loads the dashboard at http://localhost:24012 and beyond that you'll just need to run your migration (truffle migrate). A more detailed guide to using Truffle Dashboard is available here.

Using the env File¶

You will need at least one mnemonic to use with the network. The .dotenv npm package has been installed for you, and you will need to create a .env file for storing your mnemonic and any other needed private information.

The .env file is ignored by git in this project, to help protect your private data. In general, it is good security practice to avoid committing information about your private keys to github. The truffle-config.js file expects a MNEMONIC value to exist in .env for running commands on each of these networks, as well as a default MNEMONIC for the Arbitrum network we will run locally.

If you are unfamiliar with using .env for managing your mnemonics and other keys, the basic steps for doing so are below:

1) Use touch .env in the command line to create a .env file at the root of your project. 2) Open the .env file in your preferred IDE 3) Add the following, filling in your own Infura project key and mnemonics:

MNEMONIC="<YOUR MNEMONIC HERE>"
INFURA_KEY="<Your Infura Project ID>"
RINKEBY_MNEMONIC="<Your Rinkeby Mnemonic>"
MAINNET_MNEMONIC="<Your Mainnet Mnemonic>"

4) As you develop your project, you can put any other sensitive information in this file. You can access it from other files with require('dotenv').config() and refer to the variable you need with process.env['<YOUR_VARIABLE>'].
