galago

galago /ɡəˈleɪɡoʊz/ is a set of very specific, opinionated helper functions for functional-like programming in js. It’s also the name of this animal.

reduceFns

Recursively reduces an a array of functions (which can even be async) by being a typical compose function / pipe mechanism. It stops reducing the supplied arguments if one of the functions returns the specified error key in it’s response.

Info:

• @param {string} acc
• @param {exitProp} exitProp
• @param {array} fns
• @returns {Promise}

Usage example:

const fakeHttpEndpoint = (requestBody) =>
  reduceFns(
    requestBody,
    'errors',
    [
      parse,
      validate,
      transform,
      saveToDb,
    ]
  );

You can also clone the repo and run yarn run example:fakeHttp to run this sample code.
