A Seneca.js data storage plugin.
 |
This open source module is sponsored and supported by Voxgig. |
|---|
This module is a plugin for the Seneca framework. It provides an in-memory storage engine that provides a set of data storage action patterns. Data does not persist betweens runs. This plugin is most useful for early development and unit testing. It also provides an example of a document-oriented storage plugin code-base.
The Seneca framework provides an ActiveRecord-style data storage API. Each supported database has a plugin, such as this one, that provides the underlying Seneca plugin actions required for data persistence.
This plugin is loaded by default by the seneca-entity plugin that also needs the seneca-basic plugin to function properly.
If you're using this module, and need help, you can:
- Post a github issue,
- Tweet to @senecajs,
- Ask on the Gitter.
If you are new to Seneca in general, please take a look at senecajs.org. We have everything from tutorials to sample apps to help get you up and running quickly.
For code samples, please see the tests for this plugin.
Supports Seneca versions 2.x and above
All Seneca data store supported functionality is implemented in seneca-store-test as a test suite. The tests represent the store functionality specifications.
npm install seneca
npm install SenecaOpensearchStoreYou'll need the seneca toolkit to use this module - it's just a plugin.
var seneca = require('seneca')()
seneca.use('basic')
.use('entity')
// Since OpensearchStore is a default plugin, it does not need to be
// added with .use(). You can just go ahead and use it.
seneca.ready(function () {
var apple = seneca.make$('fruit')
apple.name = 'Pink Lady'
apple.price = 0.99
apple.save$(function (err, apple) {
console.log("apple.id = " + apple.id)
})
})You don't use this module directly. It provides an underlying data storage engine for the Seneca entity API:
var entity = seneca.make$('typename')
entity.someproperty = "something"
entity.anotherproperty = 100
entity.save$(function (err, entity) { ... })
entity.load$({id: ... }, function (err, entity) { ... })
entity.list$({property: ... }, function (err, entity) { ... })
entity.remove$({id: ... }, function (err, entity) { ... })The standard Seneca query format is supported:
-
.list$({f1:v1, f2:v2, ...})implies pseudo-queryf1==v1 AND f2==v2, .... -
.list$({f1:v1,...}, {sort$:{field1:1}})means sort by f1, ascending. -
.list$({f1:v1,...}, {sort$:{field1:-1}})means sort by f1, descending. -
.list$({f1:v1,...}, {limit$:10})means only return 10 results. -
.list$({f1:v1,...}, {skip$:5})means skip the first 5. -
.list$({f1:v1,...}, {fields$:['fd1','f2']})means only return the listed fields.
Note: you can use sort$, limit$, skip$ and fields$ together.
This store is an in memory store and as such does not require the need of a native driver.
The Senecajs org encourages open participation. If you feel you can help in any way, be it with documentation, examples, extra testing, or new features please get in touch.
