Class: CommandDefinitionBuilder<S, C>

Defined in: CommandDefinitionBuilder/CommandDefinitionBuilder.impl.ts:40

Command definition builder is a helper to create and define a command for a service. It helps to set all needed information like schemas and hooks. With these information, the types are automatically set and extended.

A working schema definition needs at least a command name, a short description and the function implementation.

Type Parameters

S

S extends Service

C

C extends CommandDefinitionBuilderTypes = CommandDefinitionBuilderTypes

Constructors

Constructor

new CommandDefinitionBuilder<S, C>(commandName, commandDescription, eventName?, deprecated?): CommandDefinitionBuilder<S, C>

Defined in: CommandDefinitionBuilder/CommandDefinitionBuilder.impl.ts:100

Parameters

commandName

string

commandDescription

string

eventName?

string

deprecated?

boolean = false

Returns

CommandDefinitionBuilder<S, C>

Methods

addOpenApiErrorStatusCodes()

addOpenApiErrorStatusCodes(...codes): CommandDefinitionBuilder<S, C>

Defined in: CommandDefinitionBuilder/CommandDefinitionBuilder.impl.ts:383

If a function can return other status codes, than the default ones, you should add them to openApi definition. By default, 200, 204, 400, 401 and 500 can be autogenerated in most cases. Special cases or different status codes should be added with this function.

Parameters

codes

...StatusCode[]

List of status codes

Returns
