Get started

Start by adding the package to your dependencies:

npm i @oceanprotocol/squid --save

The package exposes Ocean and Logger which you can import in your code like this:

// ES6
import { Ocean, Logger } from '@oceanprotocol/squid'

// ES2015
const { Ocean, Logger } = require('@oceanprotocol/squid')

You can then connect to a running Keeper & Aquarius instance, e.g.:

const ocean: Ocean = await Ocean.getInstance({
    // the node of the blockchain to connect to, could also be infura
    nodeUri: "http://localhost:8545",
    // the uri of aquarius
    aquariusUri: "http://localhost:5000",
    // the uri of brizo
    brizoUri: "http://localhost:8030",
    // address that brizo uses
    brizoAddress: "0x00bd138abd70e2f00903268f3db08f2d25677c9e"
    // the uri to the parity node you want to use for encryption and decryption
    parityUri: "http://localhost:9545",
    // the uri of the secret store that holds the keys
    secretStoreUri: "http://localhost:12001"
})
