how to use a javascript module in typescript
<p>I have a file called model-parser.js</p>

<p>it contains: </p>

<pre><code>var _ = require('lodash');

function getTypes(vitalsModel) {
    var vitals = _.get(vitalsModel, 'vitals');

    var rows = [];
    _.forEach(vitals, function (vital) {
        rows.unshift(Object.keys(vital));
    });

    return rows; 
} 

module.exports.getTypes = getTypes;
</code></pre>

<p>I want to use the above file in a typescript file.
What is the correct syntax?</p>
