This module provides a storage addon for Seed that allows for datasets to be stored in Redis.
Module is available through npm. To use it in your project you must also have seed installed,
as it is not provided as package.json requirement.
npm install seed seed-redis
Seed, which stands for storage-agnostic, event emitting datasets, is a library of components that provide a common API for working with data, no matter the source. These compoents are Hash, Model, Graph, and Schema. Redis can be one the many sources used in the construction eventful, data-centric applications.
Visit the Seed project page to learn more.
This storage engine can be used for both models and collections.
var Seed = require('seed')
, RedisStore = require('seed-redis').Store
, store = new RedisStore({
host: 'localhost'
, port: 6397
});
var Person = Seed.Model.extend('person', {
store: store
});
var arthur = new Person({
id: 'arthur'
, name: 'Arthur Dent'
, occupation: 'Traveller'
});
arthur.save(function (err) {
if (err) return console.error(err);
console.log('Arthur has been saved!');
});In short, since Redis is a document store, 'querying' takes place in-process.
When fetching from a Graph, seed-redis will load all documents of the requested type into memory then filter the result-set given a provided query. Queries must be written in using seed's included query language (which is very similiar to MongoDb's query style). For more information on constructing well-formed queries, check out Seed's documentation on query language.
var HitchhikersGuide = Seed.Graph.extend({
store: store
, initialize: function () {
this.define(Person);
}
});
var myGuide = new HitchhikersGuide();
myGuide.fetch('person', { 'name': { $eq: { 'Arthur Dent' } }, function (err) {
var arthur = self.get('/person/arthur');
});Tests are writting in Mocha using the Chai
should BDD assertion library. Make sure you have that installed, clone this repo, install dependacies using npm install.
$ make test
You will also need a local installation of Redis available on 'localhost:6397' without authentication. Custom test database options are not provided by default.
All issues related to this project should be posted in seed-mongodb GitHub Issues. For all general seed related issues, please visit seed's GitHub Issues. There is also a community forum is available at the Seed Google Group.
