😭 php-node: A New Way to Bring PHP and Node Together

I bet some readers have strong feelings about the idea of mixing PHP and Node.js, but this is a neat project. php-node is a native module for Node that enables the running of PHP apps within the Node environment. Why? For migrating legacy apps, building hybrid PHP/JS apps, or Node apps that simply need to call out to PHP for some reason (WordPress, maybe, as we see in this post).

🤩 Wake Up, Remix! Everything's Changing..

Big news from the Remix camp this week. About a year ago, Remix and React Router merged together reflecting their shared goals and code, but now it’s all change again. React Router is now basically what Remix originally intended to be, and so ‘Remix’ is rebooting as a model-first, low-dependency, Web API-centric full-stack framework built on Preact. It’ll no longer be a 'React framework' per se.
