Generate JSON Schema from Config Object
Application configs have deep nesting: app settings, database credentials, feature flags. This example generates a JSON Schema from a multi-level config structure so you can validate configuration files before your app starts.
What You Get
The tool produces:
- Root object schema with three top-level sections:
app,database,features - Nested schemas for
database.credentialswith its own required fields - Boolean detection:
debuganddarkModebecome"boolean" - Integer detection:
portandmaxConnectionsbecome"integer" - Array schema for
allowedOriginswith string items
How to Use
- The example loads with a sample application config in Schema mode
- The nested structure shows how each config section gets its own sub-schema
- Copy the schema and use it to validate your config files
- Replace with your actual config JSON to generate a schema for your project
Real-World Pattern
Configuration validation prevents runtime errors from missing or mistyped config values. Generate a schema from your default config, then validate user-provided or environment-sourced configs against it at startup.
