= Timer Hello World: A Camel Quarkus example
2+
:cq-example-description: An example that uses the Camel timer component to output a Hello world message to the console
3+
4+
{cq-description}
5+
6+
TIP: Check the https://camel.apache.org/camel-quarkus/latest/first-steps.html[Camel Quarkus User guide] for prerequisites
7+
and other general information.
8+
9+
== Start in the Development mode
10+
11+
[source,shell]
12+
----
13+
$ mvn clean compile quarkus:dev
14+
----
15+
16+
The above command compiles the project, starts the application and lets the Quarkus tooling watch for changes in your
17+
workspace. Any modifications in your project will automatically take effect in the running application.
18+
19+
TIP: Please refer to the Development mode section of
20+
https://camel.apache.org/camel-quarkus/latest/first-steps.html#_development_mode[Camel Quarkus User guide] for more details.
21+
22+
Then look at the log output in the console. There are log messages generated from a second route. First several message show random number `N/A` (as is defined in application.properties). Following messages show random number generated by the first route, which starts delayed.
23+
24+
As we run the example in Quarkus Dev Mode, you can edit the source code and have live updates.
25+
For example, try to change the default greeting message in `application.properties` to `Greeting`.
26+
27+
The delay of the random nember generation and period at which the timer fires can be changed by modifying configuration properties `timer.period` and
28+
`timer.delay` in `application.properties`. You can also override the default values via the command line with JVM arguments
29+
`-Dtimer.period=100 -Dtimer.delay=1000'
30+
31+
=== Package and run the application
32+
33+
Once you are done with developing you may want to package and run the application.
34+
35+
TIP: Find more details about the JVM mode and Native mode in the Package and run section of
36+
https://camel.apache.org/camel-quarkus/latest/first-steps.html#_package_and_run_the_application[Camel Quarkus User guide]
37+
38+
==== JVM mode
39+
40+
[source,shell]
41+
----
42+
$ mvn clean package
43+
$ java -jar target/quarkus-app/quarkus-run.jar
44+
...
45+
[io.quarkus] (main) camel-quarkus-examples-... started in 1.163s.
46+
----
47+
48+
==== Native mode
49+
50+
IMPORTANT: Native mode requires having GraalVM and other tools installed. Please check the Prerequisites section
51+
of https://camel.apache.org/camel-quarkus/latest/first-steps.html#_prerequisites[Camel Quarkus User guide].
52+
53+
To prepare a native executable using GraalVM, run the following command:
54+
55+
[source,shell]
56+
----
57+
$ mvn clean package -Pnative
58+
$ ./target/*-runner
59+
...
60+
[io.quarkus] (main) camel-quarkus-examples-... started in 0.013s.
61+
...
