If you’re utilizing VSC, you are able to do so by clicking on the ”Terminal” tab on the prime of your IDE, adopted by ”New terminal”:

From there, because you put in the AWS CLI in step one, configure the credentials by operating the command under:

aws configure

Operating this command prompts your terminal, and you should add your ”AWS Entry Key ID” and ”AWS Secret Entry Key”. It ought to look one thing like this:

AWS Entry Key ID [None]: AKIAIOSFODNN7EXAMPLE
AWS Secret Entry Key [None]: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
Default area title [None]: ENTER
Default output format [None]: ENTER

Mission Setup

Now that you’re accomplished with configuring your AWS credentials, this subsection covers the setup means of the appliance itself. As such, to start with, create a brand new folder and open it together with your IDE. From there, open a brand new terminal as soon as once more and run the command under: 

serverless

When operating the command above, you’re supplied with just a few choices, and on this case, select ”Starter”:

As soon as you choose this feature, you’re requested to call the venture. You possibly can both click on enter to set a default title or enter one your self:

As quickly as you title the venture, a Serverless Framework template will obtain. When it completes, your terminal will immediate you to log in. Nevertheless, for this venture, this isn’t crucial. As such, proceed by coming into ”n” and hitting enter:

Lastly, enter ”n” and hit enter as soon as extra since you don’t want to deploy the venture simply but: 

In consequence, you must now have a pattern venture much like the one under:

Subsequent up, create a brand new ”capabilities” folder: 

From there, transfer the ”handler.js” file into this folder: 

You possibly can then open the ”serverless.yml” file and set a brand new location for ”handler.js”:

Furthermore, add your Moralis API key as an surroundings variable. To take action, change the code in ”serverless.yml” with the next snippet: 

service: aws-node-project

frameworkVersion: ‘3’

supplier:
title: aws
runtime: nodejs14.x
surroundings:
MORALIS_API_KEY: ‘replace_me’

capabilities:
howdy:
handler: capabilities/handler.howdy

When you examine the code above, you’ll discover that that you must set the ”MORALIS_API_KEY” variable to equal your API key. To get the important thing, log in to Moralis, click on on the ”Web3 APIs” tab to the left, copy the important thing, and insert it into the code:

That’s it for the preliminary venture setup! Allow us to transfer on to the core improvement a part of this AWS Lambda JS tutorial!

Step 3: Growing the App

First up, open a terminal and navigate to the basis folder of your venture. You are able to do so by operating ”cd ’FOLDER_NAME’ ”. From there, you’ll be able to go forward and set up Moralis by operating the next command:

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 steadiness of a specified pockets, and the second returns the pockets’s NFTs. However, 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 change ”module.exports.howdy” with ”module.exports.handler”:

You possibly can then proceed by opening the ”serverless.yml” file and altering the perform’s title and handler. It ought to now look much like this: 

service: aws-node-project

frameworkVersion: ‘3’

supplier:
title: aws
runtime: nodejs14.x
surroundings:
MORALIS_API_KEY: ‘replace_me’

capabilities:
getNativeBalance:
handler: capabilities/getNativeBalance.handler

Subsequent up, it’s time to customise the perform 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;

You possibly can then add the code snippet under to initialize Moralis utilizing your Web3 API key specified as an surroundings variable: 

const startMoralis = async () => {
await Moralis.begin({
apiKey: course of.env.MORALIS_API_KEY
});
};

startMoralis();

Lastly, change your complete ”module.exports.handler” with the code under to implement the specified SDK technique: 

module.exports.handler = async (occasion) => {
// Get native steadiness
const nativeBalance = await Moralis.EvmApi.steadiness.getNativeBalance({
deal with: occasion.deal with,
chain: occasion.chain
});

// Format the native steadiness formatted in ether through the .ether getter
const nativeBalanceEther = nativeBalance.end result.steadiness.ether;

return {
end result: 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 steadiness
const nativeBalance = await Moralis.EvmApi.steadiness.getNativeBalance({
deal with: occasion.deal with,
chain: occasion.chain
});

// Format the native steadiness formatted in ether through the .ether getter
const nativeBalanceEther = nativeBalance.end result.steadiness.ether;

return {
end result: nativeBalanceEther
}
};

That covers the preliminary ”getNativeBalance” perform. Allow us to comply with the identical process to implement the ”getWalletNfts” perform within the following subsection! 

The getWalletNfts Perform

For this perform, that you must 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” perform 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 {
end result: JSON.stringify(nfts)
}
};

That’s it for this AWS Lambda NodeJS tutorial! When you adopted alongside this far, you now know tips on how to combine a NodeJS SDK with Lambda utilizing Moralis!

You possibly can then add an ”deal with” and ”chain” as parameters. It may look one thing like this: 

{
“deal with”: “0x99EXAMPLEADDRESS”,
“chain”: “chain_id”
}

Nevertheless, as you’ll be able to see from the code snippet, that you must add the pockets deal with from which you need the balances and the ID of the chain you need to question. From there, you’ll be able to check the capabilities, and for example, enter the next into the terminal to check the ”getNativeBalance” perform:

serverless invoke -f getNativeBalance –path occasion.json

If the check is profitable, it ought to return a message much like the one under: 

Now that you’ve got made positive that all the pieces works fantastic, all that is still is deploying your venture to AWS. To take action, be sure you are in your venture’s root folder and run the next command within the terminal:
