Introduction to Sanity.io
Sanity.io is a data storage service where you can manage content, making use of Sanity's Application Programming Interfaces (APIs), tools, and libraries. You can easily build a centralized content repository for your projects.
Sanity at its core is the data store and its query language is GROQ.
Since Sanity Studio is an open source single-page application, it can be freely modified and themed. Built using the JavaScript language, you can easily define your content structure. Then, using the ReactJS library, you are able to extend Sanity Studio's functionality with your own ReactJS components. Also, Sanity Studio enables workflow personalization for a project's content editors. Since Sanity Studio uses npm, you may contribute a plugin by creating a public package hosted on https://www.npmjs.com/, to extend its functionality.
Sanity's content is stored and accessed via its data store, which is accessible using either the Sanity.io client library or via a HyperText Transfer Protocol (HTTP) API call. Sanity.io manages the data store, which is cloud-hosted.
What is GROQ?
GROQ is a query language created by Sanity. It is used to retrieve information from the data store. GROQ is easy to learn and powerful—for example, different sets of documents can be queried into a single response.
Now that we have a high-level overview of Sanity.io, we will create our first project.
