Hi Juanse - This tutorial will work as-is with Stimulus 2; however, you'll see some warnings in your web console about deprecations related to the way that the data-targets are set.

In Stimulus 2, you'll want to set the target with something like:

<div data-comments-target="commentList" class="mb-4">

Instead of:

<div data-target="comments.commentList" class="mb-4">

The companion repo for this tutorial has been updated to use the new syntax and also implements the new CSS Classes and Values APIs:
