resolve-options

Resolve an options object based on configuration.

Usage

// This example assumes a Vinyl file

var createResolver = require('resolve-options');

var config = {
  cwd: {
    type: 'string',
    default: process.cwd
  },
  sourcemaps: {
    type: 'boolean',
    default: false
  },
  since: {
    type: ['date', 'number']
  },
  read: {
    type: 'boolean'
  }
};

var options = {
  sourcemaps: true,
  since: Date.now(),
  read: function(file) {
    return (file.extname !== '.mp4');
  }
};

var resolver = createResolver(config, options);

var cwd = resolver.resolve('cwd', file);
// cwd === process.cwd()

var sourcemaps = resolver.resolve('sourcemaps', file);
// sourcemaps === true

var read = resolver.resolve('read', file);
// Given .mp4, read === false
// Given .txt, read === true

API

createResolver([config,] [options])

Takes a config object that describes the options to accept/resolve and an options object (usually passed by a user) to resolve against the config. Returns a resolver that contains a resolve method for realtime resolution of options.

The config object takes the following structure:

config {
  [optionKey] {
    type // string, array or function
    default // any value or function
  }
}

Each option is represented by its optionKey in the config object. It must be an object with a type property.

The type property must be a string, array or function which will be passed to the value-or-function module (functions will be bound to the resolver to allow for dependent options).

A default property may also be specified as a fallback if the option isn't available or is invalid. The default value can be any value or a function (functions will be bound to the resolver to allow for dependent defaults). Note: default values are not type-validated by the value-or-function module.

resolver.resolve(optionKey, [...arguments])

Takes an optionKey string and any number of arguments to apply if an option is a function. Returns the resolved value for the optionKey.
