The Document Object

Here we will discuss the document object for Prismic when using the Javascript development kit for a React.js project.

Before Reading

This article assumes that you have queried your API and saved the document object in a variable named document.

An example response

Let's start by taking a look at the Document Object returned when querying the API. Here is a simple example of a document that contains a couple of fields.

Copy
{
  "id": "WKxlPCUEEIZ10AHU",
  "uid": "example-page",
  "type": "page",
  "href": "https://your-repo-name.prismic.io/api/documents/search...",
  "tags": [],
  "first_publication_date": "2017-01-13T11:45:21.000Z",
  "last_publication_date": "2017-02-21T16:05:19.000Z",
  "slugs": [
    "example-page"
  ],
  "linked_documents": [],
  "lang": "en-us",
  "alternate_languages": [
    {
      "id": "WZcAEyoAACcA0LHi",
      "uid": "example-page-french",
      "type": "page",
      "lang": "fr-fr"
     }
  ],
  "data": {
    "title": [
      {
        "type": "heading1",
        "text": "Example Page",
        "spans": []
      }
    ],
    "date": "2017-01-13"
  }
}
