Function: purryConfig()

purryConfig(impl, args): any

Defined in: utils/purry.ts:48

Internal

Creates a function that supports both data-first and data-last signatures where the "configuration" parameter comes first.

Pattern:

  • Data-first: fn(config, data) → result
  • Data-last: fn(config) → (data) => result

This differs from Remeda's purry which expects data-first as fn(data, ...args).

Use this for:

  • Lens operations: view(lens, source) / view(lens)(source)
  • Predicate builders: where(spec, obj) / where(spec)(obj)
  • Any function where config/spec/lens comes before data

Parameters​

impl​

any

Implementation function with signature (config, data) => result

args​

readonly unknown[]

Arguments passed to the wrapper function

Returns​

any

Either the result (data-first) or curried function (data-last)

Example​

// Define wrapper with overloads
function myFn<T>(config: Config, data: T): Result
function myFn<T>(config: Config): (data: T) => Result
function myFn(...args: unknown[]): unknown {
  return purryConfig(myFnImpl, args)
}

// Implementation
function myFnImpl<T>(config: Config, data: T): Result {
  // ... logic
}

// Usage
myFn(config, data)        // data-first
myFn(config)(data)        // data-last
pipe(data, myFn(config))  // in pipe
