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"
})

Examples

You can see how squid-js is used on:

• Integration test
• Tuna

Documentation

Docs: squid-js API Reference →

Alternatively, you can generate the raw TypeDoc documentation locally by running:

# will output to ./doc folder
npm run doc

Development

To start development you need to:

npm i
npm start

Testing

Unit Tests

For unit tests, running ganache-cli is required before starting the tests:

npm i -g ganache-cli
ganache-cli

To start unit tests, run:

npm test

or to watch for changes:

npm run test:watch

to create code coverage information:

npm run test:cover

Integration Tests

Besides a running ganache-cli instance, a locally running Ocean network is required. To do so before running the tests, use Barge:

git clone https://github.com/oceanprotocol/barge
cd barge

./start_ocean.sh --latest --no-pleuston --local-spree-node

In another terminal window, run this script and export the seed phrase:

# copies the contract artifacts once the local Ocean network is up and running
./scripts/wait_for_migration_and_extract_keeper_artifacts.sh

# export Spree accounts seed phrase
export SEED_WORDS="taxi music thumb unique chat sand crew more leg another off lamp"

Once everything is up, run the integration tests:

npm run integration

to generate code coverage information during test, run:

npm run integration:cover

Production build

npm run build

Releases

For a new patch release, execute on the machine where you're logged into your npm account:

./bumpversion path

git tag with the latest version and git push
