Build Status


Typescript type testing and validation library. See API for all methods provided.


The @fireflysemantics/is library declares @fireflysemantics/validatorts as a peer dependency.

Therefore both libraries must be installed by your application.

npm i -S @fireflysemantics/validatorts

npm i -S @fireflysemantics/is

Note that if you are using the `FESM5` package format the `tslib` peer dependency must also be installed.

npm i -S npm i tslib

# Supported Package Formats

The library is built with the Angular Package Format.  It therefore supports all these package formats (As can be seen in the provided `package.json`) and has integrated typescript definitions:

- "main": "bundles/fireflysemantics-validatorts.umd.js",
-  "module": "fesm5/fireflysemantics-validatorts.js",
-  "es2015": "fesm2015/fireflysemantics-validatorts.js",
-  "esm5": "esm5/fireflysemantics-validatorts.js",
-  "esm2015": "esm2015/fireflysemantics-validatorts.js",
-  "fesm5": "fesm5/fireflysemantics-validatorts.js",
-  "fesm2015": "fesm2015/fireflysemantics-validatorts.js",
-  "typings": "fireflysemantics-validatorts.d.ts"

## Typedoc

## Usage

We use this library to implement the validation decorators in [@fireflysemantics/validator](https://www.npmjs.com/package/@fireflysemantics/validator).  The functions can also be used to add semantic meaning to your test cases using [NPM Assert](https://www.npmjs.com/package/assert) or Jest and the same goes for general boolean logic in your source code.

For example instead of:
import { ok } from "assert";
ok(decorator != null, "The decorator is not null or undefined"); 


import { ok } from "assert";
import {isDefined} from "@fireflysemantics/is";


See the test cases. For additional detail also see the validator.js test cases.

Running unit tests

Run npm t to execute the unit tests via Jest.
