Package Exports

specs

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (specs) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Specs

specs is a modular framework to compile specification models into javascript functions.

Install

npm install specs

Usage

var assert = require('assert');
var specs = require('specs');

var engine = specs.engine();

var spec = engine.compile({
  foo: 42,
  bar: /foo+bar/
});

assert(spec({
  foo: 42,
  bar: 'foooooooobar'
});

Directives

Directives allow you to extend the grammar of your specification engine

engine.directive('lt', function (model) {
  return function (x) { return x < model; };
});

and use them in specification models

var spec = engine.compile({ $lt: 43 });

assert(spec(42));

Modules

A module is a set of directives.

You can write your own modules or reuse existing ones.

Below are officially supported modules to come

specs-comp : basic scalar comparison operators
specs-logic : basic logic operators
specs-list : basic list operators (contains, any, none of, ...)

Module usage is then like so

var engine = specs.engine('comp', 'logic', 'list');
