You may then transfer the ”handler.js” file into this newly created folder:
Lastly, it’s essential to add your Moralis API key, which you are able to do by changing the code within the ”serverless.yml” file with this snippet:
service: aws-node-project
frameworkVersion: '3'
supplier:
title: aws
runtime: nodejs14.x
setting:
MORALIS_API_KEY: 'replace_me'
capabilities:
hiya:
handler: capabilities/handler.hiya

To search out the important thing, log in to the Moralis admin panel and click on on ”Web3 APIs” to the left. From there, copy the important thing and enter it into the code:
Creating the App
With the Serverless Framework template at your disposal and the mandatory configurations accomplished, it’s now time for the central a part of this tutorial, the place we present you tips on how to add code for the Lambda app. Particularly, within the following sections, we’ll present you tips on how to create two capabilities: ”getNativeBalance()” and ”getWalletNfts()”.
Nonetheless, earlier than diving into the code for these capabilities, you need to set up the Moralis dependencies. As such, open the terminal as soon as once more, ”cd” into the venture’s root folder, and run this command:
npm set up moralis
Working the command above will set up Moralis, and also you are actually prepared to start out creating the primary ”getNativeBalance()” perform!
The “getNativeBalance()“ Perform
To kick issues off, change the title of the ”handler.js” file to ”getNativeBalance.js”:
You may then open the file and progress by changing ”module.exports.hiya” with ”module.exports.handler”:
From there, it’s essential to change the title and handler of the perform within the ”serverless.yml” file:
Subsequent, navigate again to the ”getNativeBalance.js” file and add Moralis’ ”getNativeBalance()” performance by first inputting the Moralis necessities:
const Moralis = require('moralis').default;
Following this, you need to initialize Moralis with the Web3 API key specified earlier. As such, enter the next snippet under the Moralis necessities:
const startMoralis = async () => {
await Moralis.begin({
apiKey: course of.env.MORALIS_API_KEY
});
};
startMoralis();
Lastly, the very last thing it’s essential to do is change the entire ”module.exports.handler” part with the code under. In doing so, you’ll implement the correct SDK methodology:
module.exports.handler = async (occasion) => {
// Get native stability
const nativeBalance = await Moralis.EvmApi.stability.getNativeBalance({
tackle: occasion.tackle,
chain: occasion.chain
});
// Format the native stability formatted in ether by way of the .ether getter
const nativeBalanceEther = nativeBalance.end result.stability.ether;
return {
end result: nativeBalanceEther
}
};
That covers the primary ”getNativeBalance()” perform, and you need to now have a file much like the one under:
'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({
tackle: occasion.tackle,
chain: occasion.chain
});
// Format the native stability formatted in ether by way of the .ether getter
const nativeBalanceEther = nativeBalance.end result.stability.ether;
return {
end result: nativeBalanceEther
}
};
The “getWalletNfts()“ Perform
The subsequent perform we’ll add is ”getWalletNfts()”, and we will comply with the identical steps because the preliminary perform. Nonetheless, since we beforehand used the ”handler.js” file, it’s essential to create a brand new one from scratch. As such, go forward and create a brand new file within the ”capabilities” folder referred to as ”getWalletNfts.js”:
Subsequent up, open ”serverless.yml” and add the perform to the ”capabilities” part:
Lastly, to prime issues off, add 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({
tackle: occasion.tackle,
chain: occasion.chain,
restrict: 10
});
return {
end result: JSON.stringify(nfts)
}
};
That’s it for the ”getWalletNfts()” perform! All that is still is testing and deploying the capabilities to Lambda, and we’ll present you ways to take action within the following part!
