<p><strong>Update:</strong><br>
you can use <code>this</code> keyword for accessing fastify instance in your controllers that are defined with <code>function</code> keyword. Arrow function controllers won't work.  </p>

<p>You can also decorate fastify instance on request or reply object:</p>

<p><code>index</code>:</p>

<pre><code>fastify.decorateRequest('fastify', fastify);
// or
fastify.decorateReply('fastify', fastify);

fastify.register(require('./routes/auth'), {
  prefix: '/auth'
});
</code></pre>

<p>Then in your <code>handler/auth</code>:</p>

<pre><code>module.exports = {
  getRoot: (request, reply) {
    // ACCESS FASTIFY NAMESPACE HERE
    request.fastify
    // or
    reply.fastify

    reply.code(204).send({
      type: 'warning',
      message: 'No content'
    });
  }
};
</code></pre>

<p>Here is the updated usage for the OnRequest hook for requests:</p>

<p>I need to access the fastify instance from a handler file. I don't remember at all how I should be doing that.</p>

<p>index:</p>

<pre><code>fastify.register(require('./routes/auth'), {
  prefix: '/auth'
})
</code></pre>

<p>routes/auth: </p>

<pre><code>module.exports = function(fastify, opts, next) {
  const authHandler = require('../handlers/auth')
  fastify.get('/', authHandler.getRoot)
  next()
}
</code></pre>

<p>handler/auth:</p>

<pre><code>module.exports = {
  getRoot: (request, reply) {
    // ACCESS FASTIFY NAMESPACE HERE
    reply.code(204).send({
      type: 'warning',
      message: 'No content'
    })
  }
}
</code></pre>

<p>Thanks!</p>
