fluture-sanctuary-types

Fluture type definitions for Sanctuary.

Usage

Node

$ 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.

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));
