That covers the conditions. From right here, it’s time to dive deeper into the applying code!
Tips on how to Set Up the Software
We’ll use an already pre-made software template to make this tutorial as simple as attainable. You will discover the whole GitHub repository for the venture down beneath:
Get Any Pockets Token Steadiness App Repo – https://github.com/MoralisWeb3/youtube-tutorials/tree/predominant/get-any-wallets-token-balance
So, to start with, open the repository above and clone the venture to your native listing. With a neighborhood copy of the applying, you must now have a file construction much like the one proven beneath:
In case you examine your native listing, you’ll rapidly discover that the ”.env.native” file is lacking. Thus, be sure to create this file and add the contents beneath and substitute ”YOUR_API_KEY” with the important thing you copied within the earlier part:
NEXT_PUBLIC_MORALIS_API_KEY=”YOUR_API_KEY”
Lastly, run the next command to put in the Moralis SDK:
npm set up moralis @moralisweb3/common-evm-utils
That’s really all it is advisable do to make the applying operational. Nevertheless, within the following part, we are going to break down the code to clarify the logic in additional element. By educating you the way the applying works, you possibly can apply related ideas in future growth endeavors.
Software Code Breakdown
This part will break down the important components of the code, together with the logic for the way to get the token stability of an deal with. Particularly, we are going to deal with the next three information: ”index.js”, ”header.js”, and ”predominant.js”.
”index.js” – The ”index.js” file incorporates the code for the applying’s homepage. It seems to be like this: import Head from “subsequent/head”;
import kinds from “../kinds/Residence.module.css”;
import Header from “../parts/header”;
import Fundamental from “../parts/predominant”;
export default operate Residence() {
return (
<part className={kinds.container}>
<Head>
<title>Get Token Value</title>
<meta title=”description” content material=”Generated by create subsequent app” />
<hyperlink rel=”icon” href=”https://moralis.io/favicon.ico” />
</Head>
<predominant className={kinds.predominant}>
<Header />
<Fundamental />
</predominant>
</part>
);
}
As you possibly can see on the backside of the file, the code right here is answerable for rendering two parts, ”Header” and ”Fundamental”:
<predominant className={kinds.predominant}>
<Header />
<Fundamental />
</predominant>
</part>
Now, allow us to take a short take a look at ”header.js”.
”header.js” – This file is comparatively simple and incorporates the code for the title and emblem on the high left of the applying’s UI:import Picture from “subsequent/picture”;
import kinds from “../kinds/Residence.module.css”;
import Emblem from “../public/property/Moralis_logo.png”;
export default operate Header() {
return (
<part className={kinds.header}>
<Picture src={Emblem} alt=”Emblem picture” width=”102″ peak=”82″ />
<h1 className={kinds.title}>Get Any Pockets’s Token Steadiness</h1>
</part>
);
}
Lastly, we’ve the ”predominant.js” file. Nevertheless, this file is sort of intensive in comparison with the others, and that is the place we discover a lot of the logic wanted to get the token stability of an deal with. As such, this file deserves its personal sub-section!
The ”predominant.js” File
In comparison with the 2 earlier information, ”predominant.js” is comparatively intensive. Subsequently, we’ve break up the code into smaller components to make it simpler to comply with together with. As such, allow us to initially take a better take a look at the primary 4 traces of code:
import { useState } from “react”;
const Moralis = require(“moralis”).default;
const { EvmChain } = require(“@moralisweb3/common-evm-utils”);
import kinds from “../kinds/Residence.module.css”;
This half is answerable for the mandatory imports. That is additionally the place we set up Moralis and the frequent EVM utils. Furthermore, the rest of the code is the ”Header()” operate. That is the place the central logic for getting the token stability of an deal with is discovered within the ”handleSubmit()” operate:
const handleSubmit = async () => {
deal with = doc.querySelector(“#walletAddress”).worth;
const chain = EvmChain.ETHEREUM;
await Moralis.begin({
apiKey: course of.env.NEXT_PUBLIC_MORALIS_API_KEY,
});
const response = await Moralis.EvmApi.token.getWalletTokenBalances({
deal with,
chain,
});
console.log(response.toJSON());
setResult(response.toJSON());
setShowResult(true);
doc.querySelector(“#walletAddress”).worth = “”;
};
Within the first a part of this operate, we get the deal with from the UI and retailer it within the ”deal with” variable. From there, we set the ”chain” variable to Ethereum. Subsequent up, we initialize Moralis with the ”Moralis.begin()” operate utilizing the API key from the ”.env.native” file. Lastly, we name Moralis’ ”getWalletTokenBalances()” operate, passing the ”deal with” and ”chain” variables as arguments. The returned info is saved within the ”response” variable, offering entry to all of the tokens held by the pockets deal with inputted by the person.
From there, the final a part of the code is answerable for rendering the weather of the UI. That is additionally the place we resolve what info to show to the person:
return (
<part className={kinds.predominant}>
<type
className={kinds.getTokenForm}
title=”create-profile-form”
technique=”POST”
motion=”#”
>
<label className={kinds.label} htmlFor=”walletAddress”>
Add ERC20 Pockets Tackle
</label>
<enter
className={kinds.walletAddress}
kind=”textual content”
id=”walletAddress”
title=”walletAddress”
maxLength=”120″
required
/>
</type>
<button className={kinds.form_btn} onClick={handleSubmit}>
Submit
</button>
<part className={kinds.end result}>
{showResult &&
end result.map((token) => {
return (
<part
className={kinds.tokenContainer}
key={end result.indexOf(token)}
>
<img src={token.thumbnail} />
<p className={kinds.title}>{token.title}</p>
<p className={kinds.quantity}>
{(token.stability / 10 ** token.decimals).toFixed(2)}
</p>
</part>
);
})}
</part>
</part>
);
However, that covers the whole lot of the code and this software. For a extra detailed code breakdown, please take a look at the video from the ”Tips on how to Get the Token Steadiness of an Tackle Utilizing Moralis’ Token API” part.
