Properties

[symbolFilePath]

[symbolFilePath]: string

[symbolTask]

[symbolTask]: true

OptionalcomputedDependencies

computedDependencies?: DependencyValuesType<TDependencies>

dependencies

dependencies: TDependencies | (() => TDependencies)

Access other tasks/resources/events. Can be an object or a function when you need late or config‑dependent resolution.

id

id: string

OptionalinputSchema

inputSchema?: IValidationSchema<TInput>

Optional validation schema for runtime input validation. When provided, task input will be validated before execution.

Optionalmeta

meta?: TMeta

Optional metadata used for docs, filtering and tooling.

middleware

middleware: TMiddleware

Middleware applied around task execution.

optional

optional: (() => IOptionalDependency<ITask<TInput, TOutput, TDependencies, TMeta, TTags, TMiddleware>>)

Return an optional dependency wrapper for this task.

OptionalresultSchema

resultSchema?: IValidationSchema<TOutput extends Promise<U>
    ? U
    : never>

Optional validation schema for the task result. When provided, the result will be validated immediately after the task's run resolves, without considering middleware.

run

run: ((input: HasInputContracts<[...TTags[], ...TMiddleware[]]> extends true
    ? [TInput] extends [undefined]
        ? InferInputOrViolationFromContracts<[...TTags[], ...TMiddleware[]]>
        : EnsureInputSatisfiesContracts<[...TTags[], ...TMiddleware[]], TInput>
    : TInput, dependencies: DependencyValuesType<TDependencies>) => HasOutputContracts<[...TTags[], ...TMiddleware[]]> extends true
    ? EnsureOutputSatisfiesContracts<[...TTags[], ...TMiddleware[]], TOutput>
    : TOutput)

tags

tags: TTags

Tags applied to the task that might define its behvaiour or impact the systems.
