Hot Reloading

  1. Hot reloading allows much faster iteration times inside of rsx calls by interperting them and streaming the edits.
  2. It is useful when changing the styling/layout of a program, but will not help with changing the logic of a program.
  3. Currently the cli only implements hot reloading for the web renderer.

Setup

Install dioxus-cli. Enable the hot-reload feature on dioxus:

dioxus = { version = "*", features = ["web", "hot-reload"] }

Usage

  1. run:

    dioxus serve --hot-reload
    
  2. change some code within a rsx macro

  3. open your localhost in a browser

  4. save and watch the style change without recompiling

Limitations

  1. The interperter can only use expressions that existed on the last full recompile. If you introduce a new variable or expression to the rsx call, it will trigger a full recompile to capture the expression.
  2. Components and Iterators can contain abritary rust code, and will trigger a full recompile when changed.
