A library that gives you access to the powerful Moralis Server backend from your JavaScript app.

---

⚠ WARNING: This library is dedicated to back-end projects only. You should NOT use this library for a front-end project. Keep your API key secret and don't disclose it.

Features:

• Web3 authentication
• Make Evm api and Solana api calls
• Consistent data types and utilities
• Modular package: include only what you need
• Fully Typescript ready out-of-the box

... and much more. Check the official Moralis docs for more details.

🚀 Quick start

If you're new to Moralis, check the quickstart guide in the official docs on how to get started.

If you're already familiar with Moralis and have your server set up. Then follow along to connect your SDK:

1. Install Moralis

The easiest way to integrate the Moralis SDK into your JavaScript project is through the npm module.

Install the package via npm:

npm install moralis

or yarn:

yarn add moralis

Import Moralis:

import Moralis from 'moralis';

2. Initialise Moralis

After your dependency is added, you simply need to initialize moralis via the start method:

Moralis.start({
  apiKey: '<YOUR_API_KEY>',
});

After that you can use any Moralis functionalites via, as described in our extensive docs

⚙️ Configuration

When calling Moralis.start, you can include a configuration object.

👩‍🔬 Advanced setup

It's possible to install all functionalities of Moralis by installing moralis as a dependency. But, you may choose to only install certain modules (as listed below).

1. Install the dependencies

Instead of installing moralis you can need to install the packages that you want to use. You always need to install the @moralisweb3/core package. For example:

yarn add @moralisweb3/core @moralisweb3/evm @moralisweb3/evm-api @moralisweb3/evm-wallet-connect-connector

Then at the top of your code (before any interaction with Moralis), you need to register the modules to the core package

import MoralisCore from '@moralisweb3/core';
import MoralisEvmApi from '@moralisweb3/evm-api';

const core = MoralisCore.create();
// Register all imported modules to the @moralisweb3/core module
core.registerModules([MoralisEvmApi]);

Then, initialize the app the same way as when using the umbrella moralis package. You only need to provide configation that is required by the packages. So if you don't include an api package, then you might not need to include the apiKey.

core.start({
  apiKey: '<YOUR_API_KEY>',
  // ...and any other configuration
});

Now you can use any functionality from the installed modules. The only difference is that you need to call in your code:

import MoralisEvmApi from '@moralisweb3/evm-api';

const evmApi = core.getModule<MoralisEvmApi>(MoralisEvmApi.moduleName);
evmApi.block.getBlock();

Instead of

import Moralis from 'moralis';

Moralis.EvmApi.block.getBlock();

Of course you are free to combine the modules in a single object, and use that in your dapp.

// moralis.ts
import { MoralisCore } from '@moralisweb3/core';
import EvmApi from '@moralisweb3/evm-api';

const core = MoralisCore.create();
const evmApi = EvmApi.create(core);
core.registerModules([evmApi]);

export const Moralis = {
  EvmApi: evmApi,
};

// app.ts
import { Moralis } from './moralis/';

Moralis.EvmApi.block.getBlock();
