Quick Start

1. Install SDK

A) Simple Usage: with <script> tag

For those not using any JS bundling/complilation or compilation technique or tools like Codepen or similar online Editors, please check our Import SDK bundle with <script> tag.

If you're using bundling/compilation techniques (eg. webpack), please continue reading.

B) Advanced Usage: with npm or similar

Add the latest @aeternity/aepp-sdk release from npmjs.com to your project using one of these commands

# install using npm...or yarn or pnpm
npm i @aeternity/aepp-sdk

Note: To install a Pre-Release (latest beta or alpha version) using on the latest Node version, you have to install the package appending the @next tag reference, or even use the # symbol and the Repo URL to install a version coming from a specific branch.

# install the @next version of the SDK
npm i @aeternity/aepp-sdk@next

# install the #develop version of the SDK
npm i https://github.com/aeternity/aepp-sdk-js#develop

Note : If you experience errors during the installation, you might need to install build tools for your OS.

Windows: Windows Build Tools

npm install -g windows-build-tools

Ubuntu / Debian: Build Essential

sudo apt-get update
sudo apt-get install build-essential

Mac: Download Xcode from AppStore, then run

xcode-select --install

2. Create an Account

You can do many more things now, but you'll probably have to start with:

A) Using the Command Line

Create an account using the 💻 CLI

B) Using the SDK

  import { Crypto } from '@aeternity/aepp-sdk/es'
  const keypair = Crypto.generateKeyPair()
  console.log(`Secret key: ${keypair.secretKey}`)
  console.log(`Public key: ${keypair.publicKey}`)

3. Give yourself some AE tokens

To get yourself some AEs you can use the 🚰 Faucet Aepp. Just add your publicKey, and you'll immediately get some test tokens.

4. Import (a chosen Flavor)

Import the right flavor. For this example with get the Universal flavor, which contains all the features of the SDK:

// Import Flavor
import Ae from '@aeternity/aepp-sdk/es/ae/universal' // or other flavor

5. Play with Aetenity's blockchain features

// Use Flavor
import Ae from '@aeternity/aepp-sdk/es/ae/universal' // or other flavor
import MemoryAccount from '@aeternity/aepp-sdk/es/account/memory' // or other flavor
import Node from '@aeternity/aepp-sdk/es/node' // or other flavor

Promise.all([
  Node({ url, internalUrl })
]).then(nodes => {
    Ae({
        // This two params deprecated and will be remove in next major release
        url: 'https://sdk-testnet.aepps.com',
        internalUrl: 'https://sdk-testnet.aepps.com',
        // instead use
        nodes: [
          { name: 'someNode', instance: nodes[0] },
        // node2, node3..
        ],
        compilerUrl: 'COMPILER_URL',
        // `keypair` param deprecated and will be removed in next major release
        keypair: { secretKey: 'A_PRIV_KEY', publicKey: 'A_PUB_ADDRESS' },
        // instead use
        accounts: [
          MemoryAccount({ keypair: { secretKey: 'A_PRIV_KEY', publicKey: 'A_PUB_ADDRESS' } }),
        // acc2
        ],
        address: 'SELECTED_ACCOUNT_PUB',
        networkId: 'ae_uat' // or any other networkId your client should connect to
    }).then(ae => {
      // Interacting with the blockchain client
      // getting the latest block height
      ae.height().then(height => {
        // logs current height
        console.log('Current Block Height:', height)
      }).catch(e => {
        // logs error
        console.log(e)
      })
    })
})
