title: TypeORM MongoDB populate
body: <p>I'm currently playing around with NestJS and am using MongoDB with TypeORM, and I couldn't find something similar to the <code>.populate()</code> method in Mongoose, is there a way to do it with TypeORM or should I stick to Mongoose?</p>
  <p>For example, here is a route I created with Express + Mongoose, and I want to recreate it with NestJS + TypeORM:</p>
  <pre class="lang-js prettyprint-override"><code>route.get('/:slug', async (req, res) =&gt; {
      const collection = await Collection.findOne({slug: req.params.slug}).populate('products');
  
      res.json(collection);
  });
  </code></pre>
