HowToSection builder

Creates a named section containing validated HowToStep entities. The HowToSection builder injects @type, validates synchronously, and rejects unknown properties.

Import

// Astro — shown first when Astro is selected
import { HowToSection } from '@unschema-graph/astro';

// Svelte 5
import { HowToSection } from '@unschema-graph/svelte';

// Core / Node.js
import { HowToSection } from '@unschema-graph/core';
import { HowToSectionSchema } from '@unschema-graph/core';

The HowToSectionSchema Zod schema is also exported for composition and advanced validation.

TypeScript types

import {
  HowToSectionSchema,
  type SchemaInput,
  type SchemaOutput,
} from '@unschema-graph/core';

type HowToSectionInput = SchemaInput<typeof HowToSectionSchema>;
type HowToSectionOutput = SchemaOutput<typeof HowToSectionSchema, 'HowToSection'>;

Input properties

Property	Input type	Required	Default / constraints
@id	string	No	—
name	string	Yes	non-empty
itemListElement	Array	Yes	—

The aliases above remain the exact authority for nested object types. The builder also accepts a validation configuration as its second argument and always returns @type: 'HowToSection'.

Minimal example

import { HowToSection } from '@unschema-graph/core';

const entity = HowToSection({
  "name": "Deployment",
  "itemListElement": [
    {
      "text": "Build the Astro project."
    }
  ]
});

Output

{
  "@type": "HowToSection",
  "name": "Deployment",
  "itemListElement": [
    {
      "@type": "HowToStep",
      "text": "Build the Astro project."
    }
  ]
}

Common errors

• Passing an unknown property to the strict builder.
• Using source data that is missing a required property.
• Assuming valid Schema.org guarantees a search appearance.

Validation

Use HowToSection.safeParse(input) for external data. If Schema.org supports a property that is not modeled yet, validate the entity first and then use withAdditionalProperties(). Never pass invented properties to the strict builder.
