This project pulls in my artwork that I have listed on Objkt.com, an NFT marketplace built upon the Tezos cryptocurrency blockchain. This React app uses Objkt's API via graphQL to pull in data.

You can read some general info about getting started with React.

This app is now on React 18. You should either be running Node version 16 or Node Version Manager. In the project directory, you can run:

nvm use
npm install

Thereafter, you can run npm run start to open the webpage. If you want to change any CSS, you can run gulp in a separate terminal window.

This project pulls in my own Objkt.com NFT collections as a sort of brochure site; that is to say, this does not have anything to do with NFT minting which is beyond the current scope of the project.

I wrote a custom query in ObjktQuery.jsx that pulls in graphQL data from the Objkt.com API endpoint here: https://data.objkt.com/explore/.

The key part of the query is:

query objkts {
  fa(where: {contract:
  {_in:
  ["KT1W7eBKSVZB3xhwXCX8PpMivbK19wgh21QS",
   "KT1UjcUAQWjNy4mYqUKwmBgEbu93aoos5qq5"]
   }},
   order_by: {name: asc}) {...

This points to the two smart contract ids for my collections. You can copy and paste the entire query into Objkt's graphQL explorer and adjust to your own liking within the endpoint linked to above.

To view Objkt's API documentation, go to https://data.objkt.com/docs/

Currently, images are handled locally for better performance and responsiveness. For example, we can use API data to render the matching collection id image.

img src={`/assets/nft-dist/${item.fa.contract}-${item.token_id}.jpg

If you want to pull images directly from the The InterPlanetary File System or IPFS, you could do something like this:

img src={`https://ipfs.io/ipfs/${item.thumbnail_uri.slice(7)}`}

Be aware that pulling images from IPFS will severely degrade performance, even using Objkt's thumbnail_uri image.

If you want to process images using gulp, place source images in a folder at src/assets/nft-src and then run gulp. Appropriately sized JPG and webP images will then be rendered at public/assets/nft-dist for use in this app. You should name images according to the contract and token id, for example, KT1UjcUAQWjNy4mYqUKwmBgEbu93aoos5qq5-7.jpg where the long string is the smart contract id and the -7 is the token id of the NFT in your Objkt.com collection.

This project implements the latest Sass module methods using @use and @forward dropping usage of the now legacy @import method.

The React components use CSS modules.

To measure performance on this site, ensure you are using the production build with an incognito browser. Here is the Lighthouse score below.

• Theme header
• Theme footer
• Use local images
• Implement responsive images
• Implement webP image formats
• Demo site on Netlify
• Upgrade to Node v18
• Lazy load ObjktRender using React Suspense
• Implement React Helmet for OG and Twitter card tags.

• TBD
