## Get started
|
|
|
|
Start by adding the package to your dependencies:
|
|
|
|
```bash
|
|
npm i @oceanprotocol/squid --save
|
|
```
|
|
|
|
The package exposes `Ocean` and `Logger` which you can import in your code like this:
|
|
|
|
```js
|
|
// ES6
|
|
import { Ocean, Logger } from '@oceanprotocol/squid'
|
|
|
|
// ES2015
|
|
const { Ocean, Logger } = require('@oceanprotocol/squid')
|
|
```
|
|
|
|
You can then connect to a running [Keeper](https://github.com/oceanprotocol/keeper-contracts) & [Aquarius](https://github.com/oceanprotocol/aquarius) instance, e.g.:
|
|
|
|
```js
|
|
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: "unittest",
|
|
// the address of the account (in the local parity node) used to sign messages for secret store
|
|
address: "0xed243adfb84a6626eba46178ccb567481c6e655d",
|
|
})
|
|
```

## Development
|
|
|
|
To start development you need to:
|
|
|
|
```bash
|
|
npm i
|
|
npm start
|
|
```
|
|
|
|
### Test
|
|
|
|
To start unit tests you need to:
|
|
|
|
```bash
|
|
ganache-cli &
|
|
npm run test
|
|
```
|
|
|
|
or to watch for changes
|
|
|
|
```bash
|
|
ganache-cli &
|
|
npm run test:watch
|
|
```
|
|
|
|
to create code coverage
|
|
|
|
```bash
|
|
ganache-cli &
|
|
npm run test:cover
|
|
```
|
|
|
|
This will start a watcher for changes of the code.
|
|
|
|
### Production build
|
|
|
|
```bash
|
|
npm run build
|
|
```
|
|
|
|
### npm releases
|
|
|
|
For a new **patch release**, execute on the machine where you're logged into your npm account:
|
|
|
|
```bash
