malliina / live-reload   0.6.0


Live reloading of web apps

Scala versions: 2.12
sbt plugins: 1.0

Build Status


Reloads the browser after a code change in your web app.

Static websites

When developing static websites, use this plugin as a dev server to serve files from a local directory. Any recompile triggers a browser refresh.

Server-rendered HTML

When developing backends that serve HTML, add a script to your dev HTML that watches for build events and refreshes the browser on recompilation.


  1. Add to project/plugins.sbt:

     addSbtPlugin("com.malliina" % "live-reload" % "0.6.0")
  2. Enable LiveReloadPlugin instead in build.sbt:

     val app = project
  3. Inject the JavaScript URL found in value to the HTML of your web page.

  4. When developing apps with sbt-revolver enable LiveRevolverPlugin then run sbt ~startApp. Changes to source code will reload the web page after recompilation.

Example app

Folder http4s-app contains an example http4s app with live reloading enabled.

Releasing a new version

To release a new version to Maven Central, run:

sbt release

This will push a new tag to version control, which triggers this GitHub Action that pushes artifacts to Maven Central.

Prior art

Li Haoyi's workbench:

  • Is specific to Scala.js
  • Uses libraries I'm not interested in at this time
