# fluture-sanctuary-types

[Fluture][] type definitions for [Sanctuary][].

## Usage

### Node

```console
$ npm install --save fluture-sanctuary-types
```

Note that you also need [Fluture][] and [sanctuary-def][] installed.
Sanctuary-def comes preinstalled with Sanctuary, so you could install
either one. Fluture has to be installed separately. See `package.json`
for compatible versions (defined in `peerDependencies`).

On Node 12 and up, this module can be loaded directly with `import` or
`require`. On Node versions below 12, `require` or the [esm][]-loader can
be used.

```js
import $ from 'sanctuary-def';
import sanctuary from 'sanctuary';
import {env, FutureType} from 'fluture-sanctuary-types/index.js';
import {resolve} from 'fluture/index.js';

const S = sanctuary.create ({
  checkTypes: process.env.NODE_ENV !== 'production',
  env: sanctuary.env.concat (env)
});

S.is (FutureType ($.String) ($.Number)) (resolve (42));
```

### Old Browsers and Code Pens

There's a [UMD][] file included in the NPM package, also available via
jsDelivr: https://cdn.jsdelivr.net/npm/fluture-sanctuary-types@7.1.0/dist/umd.js

This file adds `flutureSanctuaryTypes` to the global scope, or use
CommonJS/AMD when available.

```js
const $ = require ('sanctuary-def');
const sanctuary = require ('sanctuary');
const {env, FutureType} = require ('fluture-sanctuary-types');
const {resolve} = require ('fluture');

const S = sanctuary.create ({
  checkTypes: process.env.NODE_ENV !== 'production',
  env: sanctuary.env.concat (env)
});

S.is (FutureType ($.String) ($.Number)) (resolve (42));
```
