promwrap

Wraps modules, and other objects, full of callback functions in promises.

let fun = (x, cb) => cb(null, x)
let _module = {fun, prop: 'test'}

test('test basics', async t => {
  t.plan(4)
  let mod = promwrap(_module)
  t.same(mod.prop, 'test')
  t.same(mod.prop, 'test')
  t.same(await mod.fun('test1'), 'test1')
  t.same(await promwrap(fun)('test2'), 'test2')
})

API

promwrap(value<T>, {exclude: string[]|string, excludeMain: bool, own: bool}): T

Promisify all function properties of value. If value is a Function, it will be promisified instead. Members of Object.prototype are not promisified.

Returns value, wrapped by a Proxy.

• If exclude is supplied, do not promisify this prop/list of props.
• If excludeMain is truthy and value is a Function, treat value like a plain Object and promisify its props instead of value itself. In addition, members of Function.prototype will not be promisified.
• If own is truthy, only promisify the Object's "own" (in the Object.hasOwnProperty() sense) props
