JavaScript DSL

Since Camel 3.9

This DSL is experimental support level and is not recommended being used for production

The js-dsl is used for runtime compiling JavaScript routes in an existing running Camel integration. This was invented for Camel K and later ported to Apache Camel.

This means that Camel will load the .js source during startup and via the JavaScript compiler transform this into Camel routes.


The following hello.js source file:

function proc(e) {
    e.getIn().setBody('Hello Camel K!')


Can then be loaded and run with Camel CLI or Camel K.

Running with Camel K
kamel run hello.js
Running with Camel CLI
camel run hello.js
