galago

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.

🚧 Work in progress, but feel free to:

yarn add galago
# or
npm install galago --save

Or grab the source from src/index.js or lib/index.js (ES2015) and pluck it into your codebase as vendor code. The world is your oyster. ¯\_(ツ)_/¯

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 {*} acc - used to provide the initial value
• @param {array} fns - array of function to execute
• @param {?function} reducedFn - optional function with signature fn(x: Any): Boolean; if returning true, exits the call and returns the last result
• @returns {Promise}

Usage example:

const fakeHttpEndpoint = (requestBody) =>
  reduceFns(
    requestBody, // acc param
    [ // list of functions
      parse,
      validate,
      transform,
      saveToDb,
    ],
    isReduced // reducedFn param
  );

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