Overview

{
  "NpgsqlRest": {
    "CrudSource": {
      "Enabled": true,
      "SchemaSimilarTo": null,
      "SchemaNotSimilarTo": null,
      "IncludeSchemas": null,
      "ExcludeSchemas": null,
      "NameSimilarTo": null,
      "NameNotSimilarTo": null,
      "IncludeNames": null,
      "ExcludeNames": null,
      "CommentsMode": "OnlyWithHttpTag",
      "ReturningUrlPattern": "{0}/returning",
      "OnConflictDoNothingUrlPattern": "{0}/on-conflict-do-nothing",
      "OnConflictDoNothingReturningUrlPattern": "{0}/on-conflict-do-nothing/returning",
      "OnConflictDoUpdateUrlPattern": "{0}/on-conflict-do-update",
      "OnConflictDoUpdateReturningUrlPattern": "{0}/on-conflict-do-update/returning",
      "CrudTypes": ["All"]
    }
  }
}

General Settings

Setting	Type	Default	Description
Enabled	bool	true	Enable CRUD endpoint generation for tables and views.
CommentsMode	string	"OnlyWithHttpTag"	How comment annotations affect endpoint creation.

Comments Mode

Mode	Description
Ignore	Create all endpoints, ignore comment annotations.
ParseAll	Create all endpoints, parse comment annotations to modify them.
OnlyWithHttpTag	Only create endpoints for tables/views with HTTP tag in comments (default).

Schema and Name Filtering

Filter which tables and views are exposed as CRUD endpoints.

Setting	Type	Default	Description
SchemaSimilarTo	string	null	Include schemas matching this SQL SIMILAR TO pattern.
SchemaNotSimilarTo	string	null	Exclude schemas matching this SQL SIMILAR TO pattern.
IncludeSchemas	array	null	List of schema names to include.
ExcludeSchemas	array	null	List of schema names to exclude.
NameSimilarTo	string	null	Include table/view names matching this SQL SIMILAR TO pattern.
NameNotSimilarTo	string	null	Exclude table/view names matching this SQL SIMILAR TO pattern.
IncludeNames	array	null	List of table/view names to include.
ExcludeNames	array	null	List of table/view names to exclude.

Filtering Examples

Include only specific schemas:

{
  "NpgsqlRest": {
    "CrudSource": {
      "IncludeSchemas": ["api", "public"]
    }
  }
}

Exclude system tables:

{
  "NpgsqlRest": {
    "CrudSource": {
      "ExcludeSchemas": ["pg_catalog", "information_schema"],
      "NameNotSimilarTo": "%_audit"
    }
  }
}

URL Patterns

Configure URL patterns for different CRUD operation variants. Use {0} as placeholder for the default URL.

Setting	Type	Default	Description
ReturningUrlPattern	string	"{0}/returning"	URL pattern for INSERT/UPDATE/DELETE with RETURNING clause.
OnConflictDoNothingUrlPattern	string	"{0}/on-conflict-do-nothing"	URL pattern for INSERT ON CONFLICT DO NOTHING.
OnConflictDoNothingReturningUrlPattern	string	"{0}/on-conflict-do-nothing/returning"	URL pattern for INSERT ON CONFLICT DO NOTHING with RETURNING.
OnConflictDoUpdateUrlPattern	string	"{0}/on-conflict-do-update"	URL pattern for INSERT ON CONFLICT DO UPDATE (upsert).
OnConflictDoUpdateReturningUrlPattern	string	"{0}/on-conflict-do-update/returning"	URL pattern for INSERT ON CONFLICT DO UPDATE with RETURNING.

Custom URL Patterns

{
  "NpgsqlRest": {
    "CrudSource": {
      "ReturningUrlPattern": "{0}-returning",
      "OnConflictDoUpdateUrlPattern": "{0}-upsert"
    }
  }
}

CRUD Types

Enable or disable specific CRUD operations using the CrudTypes array.

Type	HTTP Method	Description
Select	GET	Read records from tables/views.
Insert	POST	Create new records.
InsertReturning	POST	Create records and return inserted data.
InsertOnConflictDoNothing	POST	Insert or ignore on conflict.
InsertOnConflictDoNothingReturning	POST	Insert or ignore with returning.
InsertOnConflictDoUpdate	POST	Upsert (insert or update on conflict).
InsertOnConflictDoUpdateReturning	POST	Upsert with returning.
Update	PUT	Update existing records.
UpdateReturning	PUT	Update and return modified data.
Delete	DELETE	Remove records.
DeleteReturning	DELETE	Remove and return deleted data.
All	-	Enable all CRUD types.

Examples

Enable all operations:

{
  "NpgsqlRest": {
    "CrudSource": {
      "CrudTypes": ["All"]
    }
  }
}

Read-only access:

{
  "NpgsqlRest": {
    "CrudSource": {
      "CrudTypes": ["Select"]
    }
  }
}

Basic CRUD without conflict handling:

{
  "NpgsqlRest": {
    "CrudSource": {
      "CrudTypes": [
        "Select",
        "Insert",
        "InsertReturning",
        "Update",
        "UpdateReturning",
        "Delete",
        "DeleteReturning"
      ]
    }
  }
}

Complete Example

Production configuration with filtering and specific CRUD types:

{
  "NpgsqlRest": {
    "CrudSource": {
      "Enabled": true,
      "IncludeSchemas": ["api"],
      "ExcludeNames": ["audit_log", "system_config"],
      "CommentsMode": "OnlyWithHttpTag",
      "ReturningUrlPattern": "{0}/returning",
      "OnConflictDoUpdateUrlPattern": "{0}/upsert",
      "OnConflictDoUpdateReturningUrlPattern": "{0}/upsert/returning",
      "CrudTypes": [
        "Select",
        "Insert",
        "InsertReturning",
        "InsertOnConflictDoUpdate",
        "InsertOnConflictDoUpdateReturning",
        "Update",
        "UpdateReturning",
        "Delete"
      ]
    }
  }
}

Minimal read-only configuration:

{
  "NpgsqlRest": {
    "CrudSource": {
      "Enabled": true,
      "CommentsMode": "ParseAll",
      "CrudTypes": ["Select"]
    }
  }
}
