Setting Array of Objects Type in TypeScript

TLDR Jameshwart asked how to set type of an array of objects in TypeScript. Jason advised them to use "object[]" and Typesense would infer the rest.

[
  {
    "name": "simple",
    "nameAndType": "simple|product_type",
    "slug": "simple",
    "type": "product_type",
    "url": "https://google.com/?product_type=simple"
  },
  {
    "name": "featured",
    "nameAndType": "featured|product_visibility",
    "slug": "featured",
    "type": "product_visibility",
    "url": "https://google.com/?product_visibility=featured"
  },
  {
    "name": "Father's Day Gift Hampers",
    "nameAndType": "Father's Day Gift Hampers|product_cat",
    "slug": "fathers-day-gift-hampers",
    "type": "product_cat",
    "url": ""
  }
]

If you just set object[] for the top level type, Typesense will infer the rest of the structure inside the nested array of objects

But if you want to for eg, only index nestedField.slug, you can define it like this:

{name: 'nestedField.slug', type: 'string[]', optional: true}
