Typesense Collection Schema Generator

Given a JSON object, this CLI utility gives you a first-draft Typesense Collection schema for the JSON object, that you can edit to suit your needs.

Usage:

npx typesense-collection-schema-generator <path_to_input_json_document_file> <path_to_output_typesense_collection_schema_json_file>

An input JSON file like this:

{
  "id": 133,
  "organization_name": "Acme Inc",
  "country": "USA",
  "full_name": "John Herrero",
  "address_string": "123 ABC Street",
  "address": {
    "line1": "123 ABC Street"
  },
  "addresses": [
    {"line1": "123 ABC Street"},
    {"line1": "234 ABC Street"}
  ],
  "tags": ["TagA", "TagB", "TagC"]
}

Will generate an output schema like this:

{
  "name": "your_collection_name",
  "fields": [
    { "name": "organization_name", "type": "string", "optional": true },
    { "name": "country", "type": "string", "optional": true },
    { "name": "full_name", "type": "string", "optional": true },
    { "name": "address_string", "type": "string", "optional": true },
    { "name": "address", "type": "object", "optional": true },
    { "name": "addresses", "type": "object[]", "optional": true },
    { "name": "tags", "type": "string[]", "optional": true }
  ]
}

[!IMPORTANT]
This schema is not meant to be used as-is. You want to review the generated schema, add facet: true for any facet fields, remove any un-indexed fields, or consider using auto-schema detection. Consider using regex field names for repeated field definitions.
