You may then go forward and transfer the ”handler.js” file into this folder:
Lastly, open the ”serverless.yml” file and exchange the contents with the code from the snippet beneath:
service: aws-node-project
frameworkVersion: ‘3’
supplier:
title: aws
runtime: nodejs14.x
atmosphere:
MORALIS_API_KEY: ‘replace_me’
features:
whats up:
handler: features/handler.whats up
Moreover, discover that it’s essential add your Moralis API key by changing ”replace_me” inside the code. You may purchase the important thing by logging into Moralis and clicking on the ”Web3 APIs” tab:
Step 3: Creating the Lambda Software
This part reveals you the right way to add the 2 features of the appliance. Nevertheless, earlier than doing so, it’s essential set up Moralis dependencies. As such, ”cd” into the mission’s root folder and run the command beneath within the terminal:
npm set up moralis
With the dependencies put in, we are going to progress by exhibiting you the right way to add the ”getNativeBalance()” operate. That operate fetches the native steadiness of a Web3 pockets. Moreover, we’ll additionally add the ”getWalletNfts()” operate, which does the identical for NFTs:
”getNativeBalance()” – To start with, rename the present ”handler.js” file to ”getNativeBalance.js”:
From there, open ”serverless.yml” and alter the operate handler and title:
Lastly, copy the code from the snippet beneath and exchange the whole lot inside the ”getNativeBalance.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 native steadiness
const nativeBalance = await Moralis.EvmApi.steadiness.getNativeBalance({
handle: occasion.handle,
chain: occasion.chain
});
// Format the native steadiness formatted in ether through the “.ether” getter
const nativeBalanceEther = nativeBalance.outcome.steadiness.ether;
return {
outcome: nativeBalanceEther
}
}; ”getWalletNfts()” – So as to add this operate, begin by creating a brand new file referred to as ”getWalletNfts.js”:
You may then open ”serverless.yml” and enter the code beneath into the ”features” part:
getWalletNfts:
handler: features/getWalletNfts.handler
Lastly, open ”getWalletNfts.js” and add the code from the next snippet:
‘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({
handle: occasion.handle,
chain: occasion.chain,
restrict: 10
});
return {
outcome: JSON.stringify(nfts)
}
};
