”getNativeBalance()” – To start with, rename the prevailing ”handler.js” file to ”getNativeBalance.js”:
From there, open ”serverless.yml” and alter the perform handler and identify:
Lastly, copy the code from the snippet under and change 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 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.outcome.stability.ether;
return {
outcome: nativeBalanceEther
}
}; ”getWalletNfts()” – So as to add this perform, begin by creating a brand new file known as ”getWalletNfts.js”:
You may then open ”serverless.yml” and enter the code under 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({
