Enables easy execution of native functions in fission.io, offering a simple setup with dependency inclusion, function registration, and specialized environment deployment for seamless function routing.
This small wrapper allows you to easilly run kotlin native functions in fission.io
Following the example of the simple echo function,
First add the dependency (com.vexdev:kotlin-fission) to your kotlin-native project:
repositories {
mavenCentral() // <- Important!
}
kotlin {
sourceSets {
val nativeMain by getting {
dependencies {
implementation("com.vexdev:kotlin-fission:1.0.0")
}
}
}
}
And then register your function in the main:
Kotlin-fission requires a specialised environment in fission.io.
This environment is available on docker-hub and can be used as follows:
import fission.FissionFunction
import fission.Function
import fission.Header
import fission.Request
fun main() {
FissionFunction.init(EchoFunction())
}
class EchoFunction : Function {
override fun onCall(request: Request, headers: List<Header>): String {
return "Content-Length: ${request.contentLength}\n" +
"URI: ${request.uri}\n" +
"Method: ${request.method}\n" +
"--- BODY BEGINS ---\n" +
"${request.content}\n" +
"--- BODY ENDS ---\n"
}
}
First, create the environment
fission environment create --name kotlin --image vexdev/fission-kotlin-env --keeparchive --version 3
Then, create your function
fission function create --name echo --env kotlin --code build/bin/native/releaseExecutable/EchoFunction.kexe
And now, you can create routes
fission route create --url /echo --function echo
curl http://localhost:$PORT/echo
Or you can test it directly with the CLI
fission function test --name echo -v2
