squid-js
🦑 JavaScript client library for Ocean Protocol oceanprotocol.com
🐲🦑 THERE BE DRAGONS AND SQUIDS. This is in alpha state and you can expect running into problems. If you run into them, please open up a new issue. 🦑🐲
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:
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
