Installation

It's super easy to get started with using Slinky, whether you're working on a new project or adding Slinky to your existing work.


Creating a New Project

The easiest way to create a new project is to use Create React Scala App. This template creates a starter project with a default Webpack-based build configuration that enables hot reloading and bundling into a production site.

You can use this template from the command line with SBT:

sbt new shadaj/create-react-scala-app.g8

Follow the prompts, and you'll be all set up with a Scala-based React application with Slinky! Check out the repo for more details on what's included with the starter project.


Adding to an Existing Project

Since Slinky is distributed just like any other Scala.js library, it's very easy to integrate into an existing project.

Add the dependencies that match your application as well as required Scala.js compiler options:

libraryDependencies += "me.shadaj" %%% "slinky-core" % "0.4.3" // core React functionality, no React DOM
libraryDependencies += "me.shadaj" %%% "slinky-web" % "0.4.3" // React DOM, HTML and SVG tags
libraryDependencies += "me.shadaj" %%% "slinky-hot" % "0.4.3" // Hot loading, requires react-proxy package
libraryDependencies += "me.shadaj" %%% "slinky-scalajsreact-interop" % "0.4.3" // Interop with japgolly/scalajs-react

scalacOptions += "-P:scalajs:sjsDefinedByDefault"

// optional, but recommended; enables the @react macro annotation API
addCompilerPlugin("org.scalameta" % "paradise" % "3.0.0-M11" cross CrossVersion.full)

Slinky supports loading React via either CommonJS or as a global object. If loading as a global object, make sure React is available as window.React and React DOM as window.ReactDOM.

While Slinky can be in a simple Scala.js app with no bundler, we highly recommend that you use webpack for bundling your application with its dependencies. The SBT plugin scalajs-bundler automates much of the process around configuring webpack, and is very useful for adding webpack to an SBT build setup.


Credits

Much credit goes to existing Scala.js libraries for React, such as scalajs-react, which provided a lot of inspiration for Slinky's design. Credit also goes to scala-js-preact, which provided the inspiration for the @react macro annotation.
