In the event you adopted the steps precisely, you must now have a mission with the same construction to the one proven within the picture under:
Nonetheless, that is solely a template, and you want to make just a few configurations. To start with, create a brand new ”features” folder:
You possibly can then transfer the ”handler.js” file into this newly created folder:
Lastly, you want 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:
identify: aws
runtime: nodejs14.x
atmosphere:
MORALIS_API_KEY: ‘replace_me’
features:
howdy:
handler: features/handler.howdy
In the event you look carefully on the code, you’ll discover the ”replace_me” half, to which you want to add the important thing. 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:
Growing the App
With the Serverless Framework template at your disposal and the required configurations accomplished, it’s now time for the central a part of this tutorial, the place we present you easy methods to add code for the Lambda app. Particularly, within the following sections, we are going to present you easy methods to create two features: ”getNativeBalance()” and ”getWalletNfts()”.
Nonetheless, earlier than diving into the code for these features, it’s essential to set up the Moralis dependencies. As such, open the terminal as soon as once more, ”cd” into the mission’s root folder, and run this command:
npm set up moralis
Operating 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 identify of the ”handler.js” file to ”getNativeBalance.js”:
You possibly can then open the file and progress by changing ”module.exports.howdy” with ”module.exports.handler”:
From there, you want to change the identify 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, it’s essential 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 you want to do is change the whole ”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({
handle: occasion.handle,
chain: occasion.chain
});
// Format the native stability formatted in ether by way of the .ether getter
const nativeBalanceEther = nativeBalance.consequence.stability.ether;
return {
consequence: nativeBalanceEther
}
};
That covers the primary ”getNativeBalance()” perform, and you must 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({
handle: occasion.handle,
chain: occasion.chain
});
// Format the native stability formatted in ether by way of the .ether getter
const nativeBalanceEther = nativeBalance.consequence.stability.ether;
return {
consequence: nativeBalanceEther
}
};
The “getWalletNfts()“ Perform
The following perform we are going to add is ”getWalletNfts()”, and we are able to comply with the identical steps because the preliminary perform. Nonetheless, since we beforehand used the ”handler.js” file, you want to create a brand new one from scratch. As such, go forward and create a brand new file within the ”features” folder known as ”getWalletNfts.js”:
Subsequent up, open ”serverless.yml” and add the perform to the ”features” part:
Lastly, to high 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({
handle: occasion.handle,
chain: occasion.chain,
restrict: 10
});
return {
consequence: JSON.stringify(nfts)
}
};
That’s it for the ”getWalletNfts()” perform! All that is still is testing and deploying the features to Lambda, and we are going to present you ways to take action within the following part!
Take a look at and Deploy an AWS Lambda Perform
Now that you’re completed with the Lambda utility and the 2 features, it’s time to be certain that every part works. As such, we are going to begin this part by exhibiting you easy methods to run a neighborhood take a look at. So, to start with, create a brand new file known as ”occasion.json”:
From there, add a pockets handle and chain ID as parameters to the file. It ought to look one thing like this:
{
“handle”: “0x99EXAMPLEADDRESS”,
“chain”: “chain_id”
}
After you have added the pockets handle and chain ID, you may run the take a look at. So, let’s say you need to attempt the ”getNativeBalance()” perform. On this case, open a brand new terminal, and run the next command:
serverless invoke -f getNativeBalance –path occasion.json
If the perform works because it ought to, the terminal ought to return a hit message much like the one down under:
As soon as you recognize that the features work as supposed, it’s essential to deploy your AWS Lambda utility. With a view to deploy the Lambda features, ensure you are within the mission’s root folder and run the next command in a brand new terminal:
serverless deploy
