Contentstack Extensions SDK
The Extensions SDK allows you to extend Contentstack’s UI by helping you create Custom Fields, Custom Widgets, and Dashboard Widgets.
Custom Fields enable users to introduce simpler interface controls, such as color picker, code editor, video selector, and more, or maybe complex micro web applications such as Shopify or Snipkart. Because of their dissociated nature, custom fields can be reused multiple times.
Custom Widgets are like micro content-processing apps that help you analyze the entry content and provide recommendations. Some of the useful widgets you can create using this type of extension are text intelligence, SEO recommendations, language translation, grammar checker and more.
Dashboard Widgets let you add powerful widgets to the stack’s dashboard that let users do more from a centralized location. Some examples of this type of extension include personal notes, recently published content, notification centre, and stack usage summary.
This SDK overview document introduces you to the concept of custom extensions.
Include the compiled version of the extension client library by adding the following line to your application.
