🧑🍳
Pure, beautiful Ruby
Phlex gives you HTML semantics in Ruby so you can use your existing skills designing object-oriented views.
PhlexStunning server-side rendered views
A little Ruby gem for building HTML and SVG view components.
🚀
Fast enough
Phlex renders HTML at ~1.4gbps per core on a MacBook Pro (M3 Max) and it doesn’t slow exponentially the more components you extract.
🚂
Rails integration
Phlex works great with Rails. It supports all Rails helpers and plays nicely with ERB, ViewComponent, Stimulus, Turbo and Tailwind.
🧰
Ruby tooling
Use tools like RubyLSP, RuboCop and SimpleCov.
🧪
Sensible isolation
Phlex components only depend on the data you pass in, making them easier to test and reuse.
🧵
HTML / SVG string-builder
You can also use the Phlex DSL to build HTML and SVG strings directly, without creating a component class.
