Contentstack - Ruby Delivery SDK

Ruby SDK for Contentstack's Content Delivery API

Contentstack is a headless CMS with an API-first approach. It is a CMS that developers can use to build powerful cross-platform applications in their favorite languages. Build your application frontend, and Contentstack will take care of the rest. Read More.

Prerequisites

You need ruby v2.0 or later installed to use the Contentstack Ruby SDK.

SDK installation and setup

Add the following code to your application's Gemfile and bundle:

gem 'contentstack'

Or you can run this command in your terminal (you might need administrator privileges to perform this installation):

gem install contentstack

Quickstart in 5 mins

Initialize SDK

You will need to specify the API key, Access token, and Environment Name of your stack to initialize the SDK:

@stack = Contentstack::Client.new("api_key", "delivery_token", "environment")

Once you have initialized the SDK, you can start getting content in your app
For Setting other regions:

Refer the below code if you want to use the Europe, Azure North America, Azure Europe, GCP North America, or GCP Europe region.

JavaScriptAndroidObjective-C.NetJavaPHPRubyPythonDartSwift
@stack = Contentstack::Client.new("api_key", "delivery_token", "environment",{"region": Contentstack::Region::<<add_your_region>>})

For Setting the Branch:

If you want to initialize SDK in a particular branch use the code given below:

@stack = Contentstack::Client.<span>new</span>("api_key", "delivery_token", "environment",{"branch": "branch"})

Note: For Europe, set the region as EU, for Azure North America and Azure Europe, set the region as AZURE_NA and AZURE_EU respectively, for GCP North America set the region as GCP_NA, and for GCP Europe set the region as GCP_EU.

Basic Queries

Get a Single Entry

To retrieve a single entry from a content type, use the code snippet given below:

@stack = Contentstack::Client.new("api_key", "delivery_token", "environment")
@entries = @stack.content_type("content_type_uid").entry("entry_uid").fetch

Get Multiple Entries

To retrieve multiple entries of a particular content type, use the code snippet given below:

@stack = Contentstack::Client.new("api_key", "delivery_token", "environment")
@entries = @stack.content_type("content_type_uid").query.fetch

Note: By default, the limit for response details per request is 100, with the maximum limit set at 250.

Paginating Responses

In a single instance, the Get Multiple Entries query will retrieve only the first 100 items of the specified content type. You can paginate and retrieve the rest of the items in batches using the skip and limit parameters in subsequent requests.

@stack = Contentstack::Client.new("api_key", "delivery_token", "environment")
@entries = @stack.content_type('category').query
           .limit(20)
           .skip(50)
           .fetch
