Course builder

Creates a Course with a provider entity or reference. The Course builder injects @type, validates synchronously, and rejects unknown properties.

Import

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

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

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

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

TypeScript types

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

type CourseInput = SchemaInput<typeof CourseSchema>;
type CourseOutput = SchemaOutput<typeof CourseSchema, 'Course'>;

Input properties

Property	Input type	Required	Default / constraints
@id	string	No	non-empty
name	string	Yes	non-empty
description	string	Yes	non-empty
provider	string | Person | Organization | LocalBusiness | EntityReference	Yes	non-empty
courseCode	string	No	—
educationalCredentialAwarded	string	No	—
inLanguage	string	No	—
offers	Offer | AggregateOffer | Array<Offer | AggregateOffer>	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: 'Course'.

Minimal example

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

const entity = Course({
  "name": "Astro fundamentals",
  "description": "Build content-driven sites with Astro.",
  "provider": "Acme Academy"
});

Output

{
  "@type": "Course",
  "name": "Astro fundamentals",
  "description": "Build content-driven sites with Astro.",
  "provider": {
    "@type": "Organization",
    "name": "Acme Academy"
  }
}

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 Course.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.
