It would be great to see some integration with some of the modern frameworks like Laravel & Vue.
Laravel's Eloquent library to add/edit database records would be useful. Their Collection library is also very powerful to manipulate data.
But working together with Laravel would be a great selling point for PHPRunner and you would see interest (and sales) from their very large community.
Also, on the front end, there's some great libraries such as Vue.js and Intercooler.js that would be nice to incorporate in some way (especially if the REST API is added in the future).
p.s.
I was able to get my current version of phprunner to work with Composer to add third party php packages and that is working nicely. I'll detail how to do so in a separate post.
Thank You!
