In this guide, you'll learn how to get started with a new zio-http project.
Before we dive in, make sure that you have the following on your computer:
- JDK 1.8 or higher
- sbt (scalaVersion >= 2.12)
As a dependency
To use zio-http, add the following dependencies in your project:
libraryDependencies += "dev.zio" %% "zio-http" % "0.0.5"
Using Dream11's g8 template
Run the following command on your terminal to set up a ZIO-HTTP project using the provided g8 template:
sbt new dream11/zio-http.g8
Efficient development process
The dependencies in the Dream11 g8 template were added to enable an efficient development process.
sbt-revolver "hot-reload" changes
Sbt-revolver can watch application resources for change and automatically re-compile and then re-start the application under development. This provides a fast development-turnaround, the closest you can get to real hot-reloading.
Start your application from sbt with the following command
Pressing enter will stop watching for changes, but not stop the application. Use the following command to stop the application (shutdown hooks will not be executed).
In case you already have an sbt server running, i.e. to provide your IDE with BSP information, use sbtn instead of sbt to run
~reStart, this let's both sbt sessions share one server.
scalafmt automatically format source code
scalafmt will automatically format all source code and assert that all team members use consistent formatting.
scalafix refactoring and linting
scalafix will mainly be used as a linting tool during everyday development, for example by removing unused dependencies or reporting errors for disabled features. Additionally it can simplify upgrades of Scala versions and dependencies, by executing predefined migration paths.
sbt-native-packager can package the application in the most popular formats, for example Docker images, rpm packages or graalVM native images.
