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",
    // 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",
    // the threshold of nodes from the secre store that have to agree to the decrypt
    threshold: 0,
    // the password for the account (in the local parity node) used to sign messages for secret store
    password: "you password",
    // the address of the account (in the local parity node) used to sign messages for secret store
    address: "0xed243adfb84a6626eba46178ccb567481c6e655d",
})
