🕴️ Server Suit 🕴️
This package was originally created to run multiple domains on a single IP address.
I recently released version 2, which adds the ability to create routers and interpolate HTML variables into objects.
This package is running most prototypes on my home server. It has 100% test coverage and was developed using TDD. Anything that could not be caught with a unit test is caught with an integration test.
It is great for microservices because it can route different websites through each other; for example, bip39 is a completely different website being routed through this site.
