npm set up moralis
Within the following two subsections, you’ll learn to create two capabilities, ”getNativeBalance” and ”getWalletNfts”. The primary returns the native token stability of a specified pockets, and the second returns the pockets’s NFTs. Nonetheless, allow us to kick issues off with the previous.
The getNativeBalance Perform
To begin with, allow us to use the already current ”handler.js” file and rename it ”getNativeBalance.js”:
From there, open the file and exchange ”module.exports.whats up” with ”module.exports.handler”:
You may then proceed by opening the ”serverless.yml” file and altering the operate’s identify and handler. It ought to now look much like this:
service: aws-node-project
frameworkVersion: '3'
supplier:
identify: aws
runtime: nodejs14.x
setting:
MORALIS_API_KEY: 'replace_me'
capabilities:
getNativeBalance:
handler: capabilities/getNativeBalance.handler
Subsequent up, it’s time to customise the operate by including Moralis’ ”getNativeBalance” performance. To take action, navigate again to ”getNativeBalance.js” and begin by including the Moralis necessities:
const Moralis = require('moralis').default;

const startMoralis = async () => {
await Moralis.begin({
apiKey: course of.env.MORALIS_API_KEY
});
};
startMoralis();
Lastly, exchange your complete ”module.exports.handler” with the code beneath to implement the specified SDK methodology:
module.exports.handler = async (occasion) => {
// Get native stability
const nativeBalance = await Moralis.EvmApi.stability.getNativeBalance({
deal with: occasion.deal with,
chain: occasion.chain
});
// Format the native stability formatted in ether through the .ether getter
const nativeBalanceEther = nativeBalance.consequence.stability.ether;
return {
consequence: nativeBalanceEther
}
};
Finally, your ”getNativeBalance.js” file ought to now look one thing like this:
'use strict';
const Moralis = require('moralis').default;
const startMoralis = async () => {
await Moralis.begin({
apiKey: course of.env.MORALIS_API_KEY
});
};
startMoralis();
module.exports.handler = async (occasion) => {
// Get native stability
const nativeBalance = await Moralis.EvmApi.stability.getNativeBalance({
deal with: occasion.deal with,
chain: occasion.chain
});
// Format the native stability formatted in ether through the .ether getter
const nativeBalanceEther = nativeBalance.consequence.stability.ether;
return {
consequence: nativeBalanceEther
}
};
That covers the preliminary ”getNativeBalance” operate. Allow us to observe the identical process to implement the ”getWalletNfts” operate within the following subsection!
The getWalletNfts Perform
For this operate, it’s good to begin by creating a brand new file within the ”capabilities” folder. On this case, allow us to name the folder ”getWalletNfts.js”:
From there, open the ”serverless.yml” file and add the next code within the ”capabilities” part:
getWalletNfts:
handler: capabilities/getWalletNfts.handler
Lastly, full the ”getWalletNfts” operate by including the next code to the ”getWalletNfts.js” file:
'use strict';
const Moralis = require('moralis').default;
const startMoralis = async () => {
await Moralis.begin({
apiKey: course of.env.MORALIS_API_KEY,
});
};
startMoralis();
module.exports.handler = async (occasion) => {
// Get pockets NFTs
const nfts = await Moralis.EvmApi.nft.getWalletNFTs({
deal with: occasion.deal with,
chain: occasion.chain,
restrict: 10
});
return {
consequence: JSON.stringify(nfts)
}
};
