```
$ npm install --save typescript-json-typesafe
```

## Usage
Get a JSON file from disk or from an http api and check it against an existing typescript interface/type. 
Useful for ci regression testing.

```js
const tsJson = require('typescript-json-typesafe');
const jsonObject = require('jsonToTest.json');

tsJson.isTypeSafe(jsonObject, 'ITestInterface');
```

## API
