Installation

npm install starfish-api --save

Usage

Starfish is pretty simple.

• Insert and retrieve data.

index.js

const starfish = require('starfish');

starfish.registerDataStore({ type: 'sqlite' });

starfish.insert({ name: 'starfish', stars: 5 }).into('applications');
// Returns unique object id

starfish.fetch().from('applications');
// All entries in table applications

API

The starfish object

When importing starfish, you get the following top-level API:

• registerDataStore
• removeDataStore
• insert
• update
• fetch
• remove

These are documented below.

registerDataStore()

Adds a new DataStore to the starfish cluster.

Args:

• options: Options object. Required.
  • options.name: Optional, unique name to identify data store. Used in logs and to remove data store. Optional.
  • options.type: The type of data store to be added. (pg, mysql, redis, mongo, rethink, sqlite) Required.
  • options.host: The hostname of the data store to be added. Defaults to localhost. Optional.
  • options.port: The port of the data store to be added. Defaults to data store's default port. Optional.
  • options.password: The password to the data store to be added. Default is empty. Optional.
  • options.database: The database to the data store to be added. Default is 'starfish'. Optional.
  • options.filename: The sqlite filename, only applies for sqlite. Defaults to starfish.sqlite3 Optional.
  • options.options: Optional parameters to be passed to the data store connection.

removeDataStore()

Removes a DataStore from the starfish cluster. Is options.name is passed, will remove that DataStore. Otherwise, data store is looked up by type, host, port and database.

Args:

• options: Options object. Required.
  • options.name: Optional, unique name to identify data store. Used in logs and to remove data store. Optional.
  • options.type: The type of data store to be added. (pg, mysql, redis, mongo, rethink, sqlite) Required.
