Create a function

Creating and updating a function requires:

Problem

You need to create a user-defined function in the current database.

Solution

Use the CreateFunction function:

Let’s create a function to allow authors to create new blog posts. We’ll set it up to allow the author to provide a title and body. This way authors are constrained by what data they can store on a post document.

({
  name: 'create_post',
  body: (
    (
      ['title', 'body'],
      (
        ('posts'),
        {
          data: {
            title: ('title'),
            body: ('body'),
          },
        },
      ),
    )
  ),
})
{
  ref: ("create_post"),
  ts: 1624310578910000,
  name: 'create_post',
  body: ((["title", "body"], (("posts"), {data: {title: ("title"), body: ("body")}})))
}
