delta-client-schema

This library is part of the Delta Client utility packages. It provides a utility to convert abstract building blocks and their values to usable data structures.

Usage

Defining a schema looks as follows consists of a root object and nested fields. For example for a building block that has a welcome message, the schema would look like this:

import { s } from "@getplate/delta-client/schema";

const heroBuildingBlock = s.object({
    title: s.primitive(c('root', 'title')),
    description: s.cast(c('root', 'description')),
    images: s.array(s.asset())
})

The schema can then be used to convert the abstract building block to a usable data structure:

import { p as parser } from "@getplate/delta-client/schema";

const heroBuildingBlock = parser.parse(schema, buildingBlockFieldFulfillments);

Yields:

const heroBuildingBlock = {
    title: "Hero Title",
    description: {
        type: 'root',
        children: [
            {
                type: 'text',
                value: 'Welcome to our website'
            }
        ]
    },
    images: [
        {
            fileName: "first image",
            url: 'https://example.com/image.jpg',
        }
    ]
}

API

Object

s.object({
    // shape of the object
})

Array

Default array with one placeholder

s.array(
    s.primitive('value')
)

Array with a limit of the maximum number of items to display

s.array(
    s.primitive('value'), 5 // limit to 5 items
)

Array with an array of placeholders, also uses this a minimum number of items to display

s.array(
    [
        s.primitive('value'),
        s.primitive('value'),
        // other fields
    ]
)

Primitive

string

s.primitive('value')

number

s.primitive(23)

Asset

Accepts a partial Asset object as a placeholder

s.asset({
    fileName: 'first',
    url: 'https://example.com/image.jpg'
})

PathPart

Accepts a partial PathPart object as a placeholder

s.pathPart({
    path: '/blogs',
})

GridPlacement

Accepts a partial GridPlacement object as a placeholder

s.gridPlacement({
    prn: 'prn:grid:123',
    row: 1
})

Cast

Accepts a correct root object to cast the schema to a usable data structure

s.cast({
    type: 'root',
    children: []
})
