NFT Minting Front-end

In this tutorial you'll learn how to create a simple NFT front-end and mint a "Go Team" NFT on the NEAR blockchain straight from your web browser.

App Overview​

The app is fairly simple: the user signs in and hits the Mint NFT button. Once the user hits the mint button, a "Go Team" NFT is minted and sent to their NEAR Wallet.

Front-end

Smart Contract code​

The code for the NFT smart contract can be found in the Zero to Hero NFT tutorial's GitHub repository, under the main branch.

The contract methods used in this application are as follows:

  • nft_mint: Function used to mint tokens.
  • check_token: Custom function created to check for the existence of a token. This helps to ensure one token per user.

Front-end​

The front-end of the contract was implemented using create-near-app. React Bootstrap was used for the styling of the application.

To bootstrap your React front-end, run the following command on your terminal:

npx create-near-app --frontend react --contract rust

Then, simply import the contract files from the main branch, and you'll have the needed structure to run the application.

Start​

Upon mounting the application's components, the app checks for the existence of a non-fungible token.

If no prior NFT has been minted, the mint button will be available for use.

Mint button​

Here is the function behind the mint button. The meta data has been filled out for the user already:

  • token_id is set by the user's account id,
  • and the media link is hard-coded to a goteam-gif.gif hosted on IPFS.

After hitting the Mint NFT button the user will be able to check out the newly minted NFT at wallet.testnet.near.org, under the Wallet's Collectibles tab.

Final remarks​

You can find the complete application repository on GitHub to clone and run. In the configuration folder you can see that this smart contract has been deployed to nft-frontend-simple-mint.blockhead.testnet:
