Project Walkthrough

Within the framework of blogchain, every blog manifests as a sophisticated smart contract, while each individual blog post is uniquely represented as a non-fungible token (NFT).

NOTE: As a standard on Mintbase as we use the latest versions of Next.js we recommend using pnpm, but the package manager is up to your personal choice.

Run the project

pnpm i

pnpm run dev

Create a Blog (deploy contract)

Step 1: check if the contract (blog) name already exists

Using @mintbase-js/data checkStoreName method we can check if the store already exists.

const { data: checkStore } = await checkStoreName(
  data.name,
  NEAR_NETWORKS.TESTNET
);

if (checkStore?.nft_contracts.length === 0) {
  (...)
}

Step 2: if contract name doesn't exist execute the deploy contract action with the instantiated wallet

Create deploy contract args using mintbase-js/sdk deployContract method.

const wallet = await selector.wallet();

const deployArgs = deployContract({
  name: data.name,
  ownerId: activeAccountId,
  factoryContractId: MINTBASE_CONTRACTS.testnet,
  metadata: {
    symbol: "",
  },
});

We can then execute the deploy contract by passing in the serverWallet as the sender

  await execute({ wallet }, deployArgs);

Create a Blog Post (mint an NFT)

Step 1: call storage method to upload file inserted by the user to arweave

Using @mintbase-js/storage uploadReference method we upload the nft image to arweave.

const metadata = {
  title: data.title,
  media: data.media,
};
const referenceJson = await uploadReference(metadata);
const reference = referenceJson.id;

Step 2: mint the nft in the contract (blog)

Create mint args using mintbase-js/sdk mint method.

const wallet = await selector.wallet();

const mintCall = mint({
  noMedia: true,
  metadata: {
    reference: reference,
    title: data.title,
    description: postContent,
    extra: "blogpost",
  },
  contractAddress: data.contract,
  ownerId: activeAccountId,
});

We can then execute the mint nft method

  await execute({ wallet }, mintCall);

Note: We populate the 'extra' field with the value 'blogpost' to subsequently filter the displayed NFTs and blogs in blogchain, ensuring that only blogs are included.

Get Data

Get blog posts (nfts) from a blog (smart contract)

Using Mintbase GraphQL Indexer we can fetch the nfts from a specific smart contract - to filter by blog post we use 'blogpost' as an extra field as explained in the previous step.

export const GET_BLOG_POSTS =
`
query GET_BLOG_POSTS($contractId: String!) {
    mb_views_nft_tokens(
      where: {extra: {_eq: "blogpost"}, _and: {nft_contract_id: {_eq: $contractId}}}
    ) {
      metadata_id
      title
      description
      media
      minted_timestamp
    }
  }
  `;

Get user blog posts (nfts)

export const GET_USER_POSTS =
`
query GET_USER_POSTS($accountId: String!) {
    mb_views_nft_tokens(
      where: {extra: {_eq: "blogpost"}, _and: {nft_contract_owner_id: {_eq: $accountId}}}
    ) {
      metadata_id
      title
      description
      media
      minted_timestamp
    }
  }
  `;

Get user blogs (smart contracts)

export const GET_USER_BLOGS =
`
query GET_USER_BLOGS($accountId: String!) {
    nft_contracts(where: {owner_id: {_eq: $accountId}}) {
      id
    }
  }
  `;

Get latest blogs (smart contracts)

export const GET_LATEST_UPDATED_BLOGS =
`
query GET_LATEST_UPDATED_BLOGS {
  mb_views_nft_metadata(
    where: {extra: {_eq: "blogpost"}}
    distinct_on: [nft_contract_id, nft_contract_created_at]
    limit: 6
    order_by: [{nft_contract_created_at: desc}, {nft_contract_id: desc}]
  ) {
    nft_contract_id
    nft_contract_owner_id
  }
  }
  `;

Get latest blog posts (nfts)

export const GET_LATEST_POSTS =
`
query GET_LATEST_POSTS {
    mb_views_nft_tokens(
      where: {extra: {_eq: "blogpost"}}
      limit: 10
      order_by: {minted_timestamp: desc}
    ) {
    metadata_id
    title
    description
    media
    minted_timestamp
    minter
    nft_contract_id
    }
  }`;

Get blog post (nft) data

export const GET_POST_METADATA =
`
query GET_POST_METADATA($metadataId: String!) {
    mb_views_nft_tokens(where: {metadata_id: {_eq: $metadataId}}) {
      metadata_id
      title
      description
      media
      minted_timestamp
      minter
      nft_contract_id
    }
  }`;

Presently, this template exclusively functions within the testnet environment. To transition to a different network, it is imperative to modify the configuration in and every 'testnet' instance.
