# resolve-options

[![NPM version][npm-image]][npm-url] [![Downloads][downloads-image]][npm-url] [![Build Status][ci-image]][ci-url] [![Coveralls Status][coveralls-image]][coveralls-url]

Resolve an options object based on configuration.

## Usage

```js
// 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:

```graphql
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`][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`.

### `resolver.resolveConstant(optionKey)`

Like `resolve`, but only returns a value if the option is constant (not a function).
