How It Works

• Type a field name → controls appear
• Clear a field name → row auto-removes
• Array / Dictionary → nested child rows appear indented
• Duplicate fields at same level → validation error
• Generate Query → downloads clean JSON (no empty rows)
• Import Query → loads and validates .json file

Field Types

String · Keyword · Number · Boolean · Date · IP · GeoPoint · Null · Array · Dictionary

Operators

equals · not equals · contains · does not contain · starts with · ends with · exists · does not exist · greater than · less than · >= · <= · in · not in · regex · wildcard · range

TODO

• Fix when running as container electron doesn't load CSS file
• Switch first step to slim image
• Add validation per picked type so no value type number equals string value
• Rewrite with BUN
