What’s NodeJS?

JS is without doubt one of the hottest programming languages on this planet. This language powers tens of millions of internet sites and internet functions. Additional, JS permits builders and designers to simply implement options. If you’re new to programming and want to study JS, make certain to enroll within the following Moralis Academy course: “Study JavaScript Programming“.

JS was initially launched in 1995 and is simply used for client-side scripting. Nonetheless, this forces builders to work with a number of languages and frameworks when constructing a full stack to attach frontend and backend parts. As such, to make JS growth extra accessible and manageable, NodeJS was launched.

NodeJS is a runtime surroundings together with every thing you would possibly must execute a program written in JS. The surroundings is a single-threaded, cross-platform, open-source runtime surroundings permitting builders to construct quick and scalable networking and server-side functions. Moreover, NodeJS runs utilizing the V8 JS runtime engine and makes use of an event-driven, non-blocking I/O (enter/output) structure. This makes this surroundings each environment friendly and efficient, in the end suggesting that NodeJS is appropriate for real-time functions.

Furthermore, NodeJS has one of many largest collections of private and non-private packages which are saved within the NPM registry, the place plenty of open supply software program is hosted, making it one of many largest open supply ecosystems that exist at this time. Because of this, this gives software program builders enormous amount of open supply instruments which are unmatched in different language ecosystems, making it simple for folks to start out JavaScript growth.

What’s extra, NodeJS is uniquely appropriate for blockchain growth making this a pretty device when creating dapps or different Web3 initiatives. So, with a greater understanding of what NodeJS is, we are able to proceed and take a better take a look at why you’ll wish to use NodeJS in your growth endeavors.

Why Use NodeJS?

As was talked about within the earlier part, NodeJS helps larger scalability and permits builders to create high-performing dapps. That is important inside the Web3 growth area, the place scalability is an ever-growing difficulty and problem. As such, builders will need to have the correct instruments to environments to fight these issues.

Nonetheless, to completely perceive the ability of NodeJS and why you’ll wish to use it when creating dapps, we’ll discover a few of its options:

Occasion-Pushed, Non-Blocking I/O Structure – This structure of NodeJS makes certain that node processes don’t lock up a whole web site or software when retrieving single responses. As such, NodeJS merely transfer on to the subsequent occasion within the queue till it’s empty.
Each Consumer and Server-Aspect – NodeJS makes JS growth extra manageable and accessible because it runs each the consumer and server-side of an online software. Additionally, NodeJS permits internet functions to run with two-way, real-time connections. This ensures that each servers and shoppers have the flexibility to provoke communications and change information freely.
Reusing Code – Programmers working JS-heavy apps can profit from the potential to reuse code. As such, you possibly can keep away from the trouble of context switching between search and edit instruments. NPM (node bundle supervisor) is thought for code reuse, the place builders can entry greater than 1,000,000 packages of their growth endeavors.

Now, with a greater understanding of NodeJS and why this surroundings is useful, we are able to take a better take a look at the Moralis NodeJS SDK for Web3 growth!

The next sections dive deep into Moralis’ NodeJS SDK for Web3 growth. The SDK makes Web3 growth considerably extra accessible, permitting you to create Web3 initiatives with ease. As such, in case you are trying to develop into a blockchain developer, comply with alongside as we discover the intricacies of Moralis’ NodeJS SDK for Web3!

The NodeJS SDK for Web3 is step one in implementing Moralis 2.0 to make Moralis appropriate with any backend. This SDK is about up in a modular style and is totally typescript supported, making it accessible so that you can use.

The equipment consists of quite a few options, together with an EVM (Ethereum Digital Machine) API, Solana API, Web3 authentication, and so on. Nonetheless, on this article, we’ll direct our consideration towards the next three areas:

EVM Chains
EVM Addresses
Token Balances

If you happen to favor watching movies to study and educate your self, make certain to take a look at the next clip from Moralis’ YouTube channel. This tutorial gives an incredible introduction to Moralis’ new NodeJS SDK for Web3 growth and some examples:

Nonetheless, we’ll moreover cowl the identical options and use instances on this article. As such, be happy to comply with alongside as we discover the NodeJS SDK for Web3 even additional! Nonetheless, earlier than taking a better take a look at the options, we’ll rapidly cowl find out how to arrange a undertaking of your personal.

Setting Up Moralis’ SDK

We are going to begin this temporary information by exhibiting you find out how to arrange your software to make use of the Moralis NodeJS SDK. It is a easy course of, and primarily based on the video above, all you want is the next snippet of code to initialize the NodeJS SDK for Web3:

Moralis.begin({
    apiKey: env.MORALIS_API_KEY,
    logLevel: 'error',
    formatEvmAddress: 'checksum',
    formatEvmChainId: 'decimal',
});

All we actually do right here is name the ”Moralis.begin()” perform and supply an API key. Moreover, you possibly can moreover see different choices equivalent to ”logLevel”, ”formatEvmAddress”, and ”formatEvmChainId”.

From the snippet above, ”logLevel” is about to ”error”. Nonetheless, in case you are trying to debug, this may be modified to, for instance, ”verbose”. What’s extra, the extra choices are used to format addresses and chain IDs.

Nonetheless, that’s it for establishing your undertaking. If you need much more detailed data on find out how to get going with a brand new undertaking, make certain to take a look at the official Moralis 2.0 documentation. For instance, take a better take a look at the “Your First Dapp” part and learn to use the NodeJS SDK for Web3!

NodeJS SDK for Web3 – EVM Chains

Now that you understand how to arrange a undertaking, we’ll proceed by taking a better take a look at the two.0 model of the SDK and the way it handles EVM blockchains. Probably the most vital distinction is that the NodeJS SDK doesn’t deal with the chains as decimals or hex strings. As an alternative, Moralis now handles these chains like separate class cases referred to as ”Moralis information sorts”.

You possibly can create a brand new class occasion via one of many following two code snippets:

const chain = EvmChain.ETHEREUM; 
EvmChain.create(1);

After getting created the category occasion, you possibly can entry varied data. For instance, here’s a checklist of instructions you need to use:

console.log('decimal', chain.decimal);
console.log('hex', chain.hex);
console.log('format', chain.format());
console.log('identify', chain.identify);
console.log('foreign money', chain.foreign money);

The preliminary two strains will console log this occasion’s decimal and hex values. Furthermore, you even have the “format()” perform. This perform will format this data primarily based on the conditions we specified within the earlier part when initiating the SDK:

That is important since this perform will likely be referred to as on any EVM API endpoint. So, if the EVM API returns a sequence in one of many information responses, it will likely be formatted primarily based in your specs from above. Furthermore, together with the “format()” perform, there are some utility strategies to get the identify or information about native tokens. Nonetheless, this isn’t all there may be to the API. You possibly can moreover take a look at the Moralis 2.0 docs concerning the EVM API to study extra about this device!

What’s extra, if you wish to develop EVM-compatible dapps, make certain to take a look at Moralis’ Ethereum dapp API or Polygon dapp API. These instruments let you create Ethereum dapps or construct a Polygon dapp simply and effectively!

NodeJS SDK for Web3 – EVM Addresses

Subsequent up, we’ll look intently at how the NodeJS SDK for Web3 works with an EVM tackle. That is what it’d appear like in a undertaking:

const tackle = EvmAddress.create(EVM_ADDRESS); 
console.log('lowercase', tackle.lowercase);
console.log('checksum, tackle.checksum);
console.log('format', tackle.format());

The very first thing we do right here is to create an tackle utilizing a lowercase string. When the tackle is created, you possibly can learn the lowercase string, checksum, name the “format()” perform, and so on., which we, on this case, console log. As such, you’ve gotten a number of choices in terms of EVM addresses.

As a reminder, you possibly can test the documentation for extra data on this!

NodeJS SDK for Web3 – EVM API

On this part, we take a look at how the EVM API works and, extra particularly, the way you question balances. In comparison with the earlier model of the SDK, we now confer with the API as “EvmApi” as a substitute of “Web3Api”. What’s extra, for Solana, we now have “SolApi” as effectively, relying on which community you might be creating.

As an instance how this works, we now have a fast instance the place we question the token stability on Ethereum for a specific tackle. That is what the code seems to be like:

const tokenResponse = await Moralis.EvmApi.account.getTokenBalances({
    chain: EvmChain.ETHEREUM,
    tackle: ETHEREUM_ADDRESS
})

console.log('Json outcome', tokenResponse.toJSON()[0]);
console.log('Direct api outcome', tokenResponse.uncooked[0]);
console.log('Information with dataTypes', tokenResponse.outcome[0]);

As you possibly can see, we name the ”getTokenBalances()” perform the place the chain and tackle are specified. A vital distinction between the earlier SDK and the brand new model is that the information concerning token balances are returned in three alternative ways.

First, it’s returned with a “toJSON()” perform, which returns the values as primitive information sorts that may be immediately utilized in your functions. Accordingly, you do not want to fret about parsing any returned information.

Second, the SDK returns the outcomes containing all the interior information sorts. If you happen to use this internally, you’ve gotten entry to all of the utility capabilities of the SDK. Lastly, Moralis moreover returns the uncooked information because it comes from the API. Nonetheless, some information continues to be formatted to make it extra constant.

That’s it for this brief information! Hopefully, you higher perceive Moralis’ NodeJS SDK for Web3 and the way it capabilities. It’s now as much as you to make use of this data when creating dapps, as Moralis is appropriate with most backends.
