JSON Schema Lookup via SchemaStore

Query schemastore.org's catalog of public configuration file schemas to validate structure, discover options, and check allowed values.

API

  • Catalog: https://www.schemastore.org/api/json/catalog.json
    • Structure: { "schemas": [{ "name", "description", "fileMatch", "url", "versions"? }] }
  • Individual schemas: Fetch the url from the matching catalog entry

Workflow

1. Find the schema

Search the catalog by name or filename pattern:

# Search by name (case-insensitive)
curl -s https://www.schemastore.org/api/json/catalog.json | jq '.schemas[] | select(.name | test("tsconfig"; "i")) | {name, url, fileMatch}'
