A helper that I use often in my projects is a function that is like _.flow, but supports an extra argument I call config, which is passed to all functions that I am composing, along with the value.

Reference implementation:

export const flowWithConfig = (...f) => (arg, config)=> f.reduce((res, f) => f(res, config), arg)

Usage:

const foo  = (val, config) => {
  if (config.prop) {
    return doSomething(val)  
  } else {
    return doSomethingElse(val)
  }
}
const bar = (val, config) => someFunction(val, config.prop2)


const composite = flowWithConfig(foo, bar)

composite(val, {prop: true, prop2: false }
