Jump start an end-to-end devonfw sample application.

Prerequisites

  • User should have Java, Angular development experience

Learning goals

  • After completing this tutorial, you will have learned about a devonfw sample application Jump-The-Queue and its architecture.

More information about Jump The Queue on https://github.com/devonfw/jump-the-queue

restoreDevonfwIde(["java", "mvn", "node", "ng", "npm"])

First, clone the Jump-The-Queue Repository.

Build and Run Java Server

buildJava("jump-the-queue/java/jtqj", true) runServerJava("jump-the-queue/java/jtqj/server", { "startupTime": 40, "port": 8081, "path": "jumpthequeue" })

Now the Java Server should be running.

In the next steps we want build and run the Angular Frontend Server. For that you need to install the dependencies first.

npmInstall("jump-the-queue/angular")

Now build and run the Angular Server. The following two steps are only needed in this tutorial. Normally you can simply execute "ng serve", open the https://localhost:4200/ and start using the app. In the next step you need to change the Base URL for the REST Services.

Serve the Frontend Server

changeFile("jump-the-queue/angular/src/environments/environment.ts", {"content": "https://-8081-.environments.katacoda.com/jumpthequeue/services/rest", "placeholder": "http://localhost:8081/jumpthequeue/services/rest"}) runClientNg("jump-the-queue/angular", { "startupTime": 200, "port": 4200, "path": "" })

Now the Angular Frontend Server should be running.
