- Growing the Lambda Utility
So, with out additional ado, let’s kick issues off by masking the required conditions!
Step 1: Protecting the Conditions
To create this AWS Lambda app with a number of capabilities, you’ll want to cowl the next seven conditions:
- Create a Moralis account
- Set up an built-in growth atmosphere (IDE)
- Arrange an AWS account
- Set up NodeJS
- Arrange the AWS CLI
- Set up Serverless Framework
- Create an IAM Consumer
Most conditions are simple and will be handled utilizing the hyperlinks above. Nonetheless, there are some things you’ll want to think about when creating the IAM consumer. To create the consumer, log in to AWS’ Administration Console and open the IAM console. You then must click on on ”Customers” and ”Add customers” within the navigation bar. Consequently, it ought to take you to the next web page:
When you arrive on the web page above, add a username and ensure to incorporate each credential sorts. When transferring on to the second half, verify the field for ”AdministratorAccess”:
Lastly, cowl the remaining steps till you attain the final one, the place you’ll want to be sure that you obtain your AWS credentials in a ”.csv” file:
Step 2: Setting Up a New Challenge
On this second step, we’ll present you how one can arrange the mission. Nonetheless, earlier than doing so, you’ll want to configure your AWS credentials. As such, open your IDE, launch a brand new terminal, and run the next command:
aws configure
When you run the command above, it’ll immediate you to enter your ”AWS Secret Entry Key”. Following this, you will need to add your ”AWS Entry Key ID”. Lastly, there can be two remaining prompts, for which you solely must hit ”enter”. All in all, 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
Challenge Setup
With the AWS credential configurations full, we’ll now present you how one can arrange the mission. To start with, create a brand new folder. Then, open it together with your IDE, and run the next command in a brand new terminal:
serverless
This may set off your terminal, and you will need to make a couple of choices. For the primary query, choose the ”Starter” choice:
Subsequent up, title your mission by inputting a reputation or instantly hit ”enter”:
Whenever you title the mission, it can autonomously obtain a brand new Serverless Framework template. As soon as it completes, the terminal will ask you to log in. For now, you’ll be able to skip this by inputting ”n” and hitting ”enter”:
From there, you’ll be requested if you wish to deploy the mission. You’ll be able to put this off for now by as soon as once more inputting ”n” and hitting “enter”:
Consequently, you need to now have a pattern mission in your native listing wanting one thing like this:
Subsequent up, add a brand new folder referred to as ”capabilities”:
You’ll be able to then go forward and transfer the ”handler.js” file into this folder:
Lastly, open the ”serverless.yml” file and substitute the contents with the code from the snippet under:
service: aws-node-project
frameworkVersion: '3'
supplier:
title: aws
runtime: nodejs14.x
atmosphere:
MORALIS_API_KEY: 'replace_me'
capabilities:
hiya:
handler: capabilities/handler.hiya
Moreover, discover that you’ll want to add your Moralis API key by changing ”replace_me” throughout the code. You’ll be able to purchase the important thing by logging into Moralis and clicking on the ”Web3 APIs” tab:
Step 3: Growing the Lambda Utility
This part exhibits you how one can add the 2 capabilities of the applying. Nonetheless, earlier than doing so, you’ll want to set up Moralis dependencies. As such, ”cd” into the mission’s root folder and run the command under within the terminal:
npm set up moralis
With the dependencies put in, we’ll progress by displaying you how one can add the ”getNativeBalance()” perform. That perform fetches the native steadiness of a Web3 pockets. Moreover, we’ll additionally add the ”getWalletNfts()” perform, 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 perform handler and title:
Lastly, copy the code from the snippet under and substitute all the things throughout 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({
tackle: occasion.tackle,
chain: occasion.chain
});
// Format the native steadiness formatted in ether by way of the “.ether” getter
const nativeBalanceEther = nativeBalance.end result.steadiness.ether;
return {
end result: nativeBalanceEther
}
};
- ”getWalletNfts()” – So as to add this perform, begin by creating a brand new file referred to as ”getWalletNfts.js”:
You’ll be able to then open ”serverless.yml” and enter the code under into the ”capabilities” part:
getWalletNfts:
handler: capabilities/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({
tackle: occasion.tackle,
chain: occasion.chain,
restrict: 10
});
return {
end result: JSON.stringify(nfts)
}
};
Now that covers the 2 capabilities and the whole thing of the Lambda utility. From right here, all that continues to be is to check and deploy the applying to AWS. As such, we’ll take the final part to point out you the way to take action!
Testing and Deploying the Utility
Allow us to begin by testing the capabilities to make sure all the things works as meant. As such, progress by creating a brand new file referred to as ”occasion.json” within the mission’s root folder:
From there, you’ll want to add two parameters to this file, ”tackle” and ”chain”:
{
"tackle": "0x99EXAMPLEADDRESS",
"chain": "chain_id"
}
Nonetheless, ensure you add the tackle of the pockets you need to monitor and the chain ID of the blockchain you need to question. With the parameters added, you’ll be able to take a look at every perform. To take action, run the command under and swap ”FUNCTION_NAME” with the perform’s precise title:
serverless invoke -f “FUNCTION_NAME” --path occasion.json
If you happen to take a look at ”getNativeBalance()”, it ought to return the next message if all the things works as meant:
As soon as you might be pleased with the outcomes, you’ll be able to deploy them by navigating to the foundation folder of the applying in your terminal and working the next command:
