An open source [node package](https://www.npmjs.com/package/artblocks) for reading on-chain Art Blocks data and recreating generative art projects. By default the package reads data via the [ArtBlocks Subgraph](https://thegraph.com/explorer/subgraph/artblocks/art-blocks). For those using other languages, use this package as a how-to guide for working directly with ArtBlocks on-chain data.

## Installation

```bash
npm i artblocks
```

## Usage

```javascript
import ArtBlocks from 'artblocks'

// Ethereum mainnet
let artblocks = new ArtBlocks("thegraph", "mainnet")

// Artist staging projects
// Please refrain from sharing these projects publicly
let artblocks = new ArtBlocks("thegraph", "goerli")

// Flex contracts
let artblocks = new ArtBlocks("thegraph", "goerli", contracts=["<contract_address>"] flex=true)
```
