USE IT IN YOUR DAPP

Here we'll see the simplest example to request indexer data from a node application. We'll use the simple request used in the playground section.

First of all, in a new folder, create 2 files:

package.json

{  "name": "indexer-request-sample",  "version": "1.0.0",  "description": "",  "main": "index.js",  "type": "module",  "scripts": {    "test": "echo \"Error: no test specified\" && exit 1"  },  "author": "",  "license": "ISC",  "dependencies": {    "graphql-request": "^5.0.0"  }}

index.js

import { request } from "graphql-request"const getLastListedNFTs = async () => {    const gqlQuery = `{      nftEntities(        first: 10,         offset: 0,         orderBy: TIMESTAMP_LIST_DESC      ) {        totalCount        nodes {            nftId            owner            creator            collectionId            offchainData        }      }    }`    const response = await request("https://indexer-alphanet.ternoa.dev/", gqlQuery)    if (response.nftEntities){        console.log("Total count", response.nftEntities.totalCount)        response.nftEntities.nodes.forEach(x => console.log(x))    }}getLastListedNFTs()

Now open a terminal in this folder and run the following commands:

npm install
node index.js
