# Non Fungible Tokens

### Start coding

Create a new file or edit `index.ts`

```javascript
import {  Client,  Wallet }  from "xrpl" 

const client = new Client("wss://s.altnet.rippletest.net:51233")


const main = async () => {
  console.log("lets get started...");
  await client.connect();

  // do something interesting here


  await client.disconnect();
  console.log("all done!");
};

main();
```

Running this to ensure everything works should log a few things to the console. If you are running this from your node environment, don't forget to run`npm i xrpl` to add it to your project.

#### Creating NFT

First, to create digital art, you need to create an NFT using `NFTokenMint`. You need one available wallet for that. For an NFT to host metadata and have specific attributes, we usually provide a JSON file for the metadata. You can gain a better understanding of the OpenSea metadata standards (<https://docs.opensea.io/docs/metadata-standards>). When creating the NFT, you will use a URI field to include the URI to the metadata of the NFT you want to create.

```typescript
import { convertStringToHex, NFTokenMint, NFTokenMintFlags, NFTokenCreateOffer } from 'xrpl';

const { wallet: wallet1, balance: balance1 } = await client.fundWallet()    
console.log('wallet1', wallet1)

const uri = "My super NFT URI"

const nftMintTx: NFTokenMint = {
    TransactionType: "NFTokenMint",
    Account: wallet.address,
    URI: convertStringToHex(uri),
    Flags: NFTokenMintFlags.tfBurnable + NFTokenMintFlags.tfTransferable, // Burnable in case no one is buying it
    NFTokenTaxon: 0, // Unique identifier for the NFT type
}

const prepared = await client.autofill(nftMintTx)
const signed = wallet.sign(prepared)
const result = await client.submitAndWait(signed.tx_blob)
const nftId = nftId: (result.result.meta as NFTokenMintMetadata)?.nftoken_id as string

console.log("NFT ID " + nftId + " created")
```

At this point, you should have one account with an NFT created.

#### Putting your NFT on sale

Once you have your NFT, you may want to put it on sale and allow people to bid on it. Thanks to XRPL built-in functions, the NFT marketplace is already provided within the ledger. We only need to use `NFTokenCreateOffer` to put our NFT up for sale.

```javascript
import { NFTokenCreateOffer } from 'xrpl';

const nftCreateOfferTx: NFTokenCreateOffer = {
    TransactionType: "NFTokenCreateOffer",
    Account: wallet.address,
    Destination: destination, // Optional if precised it would precised the offer for a specific address
    NFTokenID: nftId,
    Amount: "0", // 0 would represent a gift to someone
    Flags: 1 // Sell offer
};

const prepared = await client.autofill(nftCreateOfferTx)
const signed = wallet.sign(prepared)
const result = await client.submitAndWait(signed.tx_blob)
const offerId = (result.result.meta as NFTokenCreateOfferMetadata)?.offer_id as string

console.log("Offer ID " + offerId + " created")
```

At this point, your NFT should be on sale, and it will be available for someone specific or anyone to buy.

### Extra credits

**Canceling your offer**

You can cancel your NFT offer, you will need to use the NFTokenCancelOffer function to do so (<https://xrpl.org/docs/references/protocol/transactions/types/nftokencanceloffer/>)

**Burning your NFT**

You can burn your NFT, you will need to use the NFTokenBurn function to do so (<https://xrpl.org/docs/references/protocol/transactions/types/nftokenburn/>)
