| = Writing Integrations in JavaScript |
| |
| [WARNING] |
| ==== |
| The JavaScript DSL is current in preview support level. |
| ==== |
| |
| An integration written in JavaScript looks very similar to a Java one: |
| |
| [source,js] |
| .hello.js |
| ---- |
| function proc(e) { |
| e.getIn().setBody('Hello Camel K!') |
| } |
| |
| from('timer:tick') |
| .process(proc) |
| .to('log:info') |
| ---- |
| |
| To run it, you need just to execute: |
| |
| ``` |
| kamel run hello.js |
| ``` |
| |
| For JavaScript integrations, Camel K does not yet provide an enhanced DSL, but you can access some global bounded objects such as a writable registry and the camel context so to set the property _exchangeFormatter_ of the _LogComponent_ as done in previous example, you can do something like: |
| |
| [source,js] |
| ---- |
| |
| l = context.getComponent('log', true, false) |
| l.exchangeFormatter = function(e) { |
| return "log - body=" + e.in.body + ", headers=" + e.in.headers |
| } |
| ---- |
| |
