Lightweight pluggable CMS in Node.js with an admin interface and RESTful API

Features:

  • Admin interface
  • Respectable read/write REST+JSON API
  • Pluggable file storage
  • User management w/ roles and permissions
  • Workspaces for multi-tentant support
  • Optional Passport / OAuth integration
  • Custom fields via plugins
  • Events via EventEmitter radio
  • Basic searching & sorting

Getting Started

Create app.js for your project:

var showcase = require('showcase');

showcase.initialize({
  "database": {
    "dialect": "mysql",
    "host": "localhost",
    "database": "cms",
    "username": "cms",
    "password": "cms"
  },
  "files": {
    "tmp_path": "/var/tmp",
    "storage_path": "/var/tmp"
  },
  "port": 3000
});

showcase.run();

Initialize the database schema:

$ node --harmony-generators app schema-sync

Initialize the application fixtures data:

$ node --harmony-generators app fixtures-sync

Start your server:

$ PORT=4000 node --harmony-generators app run

Once your app is running, create an admin user and log in. Then create a workspace, then create some collections, and start adding items.

Node version 0.11.3 is recommended. Showcase requires support for ES6 generators, so node v0.11.2 or greater. You may also try your luck with gnode and node v0.10.x. Also note that if you need sqlite support, node v0.11.3 is the latest supported version of node for that library.

Workspaces, Collections, and Items

Start by creating a new workspace. A workspace can have an administrator, and will contain a set of collections. You may often want to create a workspace per website, or per project.

Within a workspace, create collections. A collection is a set of like items. Other CMSs might call a collection a "content type" or "custom post type". In a relational database, a collection would be analogous to a table. Define a collection and its fields, and then use the admin interface to add items.

Access and modify data in collections through the built-in RESTful API.

Showcase API

showcase.initialize(options)

Initialize the application, given a set of options:

Sepcify authentication and authorization parameters under the auth key:

  • auth.passport_strategy specifies an instance of a passport strategy; defaults to local authentication

Specify database connection details under the database key:

  • database.dialect can be mysql, postgres, or sqlite
  • database.storage specifies the file on disk for the sqlite dialect
  • database.host specifies the database connection host
  • database.port specifies the database connection port
  • database.database specifies the database database name
  • database.username sepcifies the database username
  • database.password specifies the database password
  • database.logging is a boolean to specify whether to log each database query
  • database.define is a passthrough to Sequelize's default model definitions for any extra customization

Under the hood these are sent through to the Sequelize constructor.

  • files.tmp_path specifies where incoming uploaded files should be stored during transfer
  • files.storage_path specifies long term storage where uploaded files should reside
  • files.store specifies a function to store an uploaded file; defaults writing to files.storage_path
  • files.retrieve specifies a function to retrieve a stored file
  • files.public_url specifies a function to generate a public url for a stored file
  • files.name specifies a function to generate a filename for an uploaded file

By default files will be stored directly to files.storage_path, but you may override this functionality by specifying override methods to store and retrieve, etc. These override methods take a callback as a parameter and are bound to File instances. See examples/files.js for an example.

And other various top-level configuration options:

  • port specifies the TCP port to listen on
  • secret specifies the secret used to hash session data (anything random enough will do)

showcase.registerField(field)

Register a custom field. Supplied field should be an object specifying the following keys:

field.config

An object containing configuration information for the field. Specify the following options:

  • name - name of the custom field type
  • inflate - function to populate item value from stored field data; accepts field, data, models, and callback parameters
  • preview - function to provide a lightweight preview of the data for rendering in HTML lists; accepts a data parameter containing the stored data
  • validator - function to validate input
field.style

A string containing CSS to style field elements

field.script

A string containing JavaScript library code to be executed on forms containing this field

field.template

A Swig template for rendering the form field

showcase.run()

Start up the server. Specify the HTTP port either via a PORT environment variable, or through a port key in options sent to showcase.initialize.

Events

Subscribe to change events through showcase.radio, an event emitter. For example to log changes to items:

showcase.radio.on('itemUpdate', function(item) {
    console.log("item was updated ", item);
})
itemUpdate

Fires when an item is updated. Receives the updated item as a parameter.

itemCreate

Fires when an item is created. Receives the nascent item as a parameter.

itemDestroy

Fires when at item is destroyed. Receives the moribund item as a parameter.
