I am actually a PHP developer and know Laravel as well. However I decided to use NodeJS for a new project and so I came across AdonisJS. The similarity is obvious.
I actually like the concept of Laravel and so I like AdonisJS because it helped me to quick start the projects.
The community is not as large as Laravel's one but I see good activity within it. The fact that the maintainer has now release version 3.0 shows that the project is moving forward and new features are added continuously.
My opinion is, that AdonisJS will get momentum in short time and the community will grow soon.
