HowToStep builder

Creates a reusable HowToStep entity. The HowToStep builder injects @type, validates synchronously, and rejects unknown properties.

Import

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

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

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

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

TypeScript types

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

type HowToStepInput = SchemaInput<typeof HowToStepSchema>;
type HowToStepOutput = SchemaOutput<typeof HowToStepSchema, 'HowToStep'>;

Input properties

Property	Input type	Required	Default / constraints
@id	string	No	—
name	string	No	—
text	string	Yes	non-empty
image	string | ImageObject	No	non-empty
url	string	No	—

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: 'HowToStep'.

Minimal example

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

const entity = HowToStep({
  "text": "Build the Astro project."
});

Output

{
  "@type": "HowToStep",
  "text": "Build the Astro project."
}

• External sources: Schema.org HowToStep

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 HowToStep.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.
