shapey/es/mergeSpec.js

A simple syntax for remapping objects, inspired by several of Ramda's spec based functions

"use strict";

exports.__esModule = true;
exports.default = void 0;

var _curry = _interopRequireDefault(require("vanillas/curry"));

var _combine = _interopRequireDefault(require("./combine"));

var _mapSpec = _interopRequireDefault(require("./mapSpec"));

function _interopRequireDefault(obj) { return obj && obj.__esModule ? obj : { default: obj }; }

/**
 * Similar to [Ramda's applySpec()](http://ramdajs.com/docs/#applySpec), however the spec will be applied and then merged into the original input.
 * Ramda's applySpec() will omit the original input, returning an object containing _only_ the props named in your spec, but this function here will apply the spec and then merge back it into the original input.
 *
 * @function
 * @name mergeSpec
 * @sig {k: v} -> {k: v} -> {k: v}
 * @param {Object} spec An object whose values are functions which expect the entire object to be fed in as input.  This is identical to the input you'd pass into applySpec()
 * @param {Object} input An object to be mapped over (transformed)
 * @returns {Object} The input object with all the transform functions applied at the named keys
