Package Exports

schema-dts

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (schema-dts) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

npm install schema-dts

Then you can use it by importing "schema-dts".

Examples

Defining Simple Properties

import {Person} from "schema-dts";

const inventor: Person = {
    "@type": "Person",
    "name": "Grace Hopper",
    "disambiguatingDescription": "American computer scientist",
    "birthDate": "1906-12-09",
    "deathDate": "1992-01-01",
    "awards": [
        "Presidential Medal of Freedom",
        "National Medal of Technology and Innovation",
        "IEEE Emanuel R. Piore Award",
    ]
};

Using 'Context'

JSON-LD requires a "@context" property to be set on the top-level JSON object, to describe the URIs represeting the types and properties being referenced. schema-dts provides the WithContext<T> type to facilitate this.

import {Organization, Thing, WithContext} from "schema-dts";

export function JsonLd<T extends Thing>(json: T): string {
    return `<script type="application/ld+json">
${JSON.stringify(json)}
</script>`;
}

export const MY_ORG = JsonLd<Organization>({
    "@context": "https://schema.org",
    "@type": "Corporation",
    "name": "Google LLC"
});
