# Flow Dependency Injection with CDI (Weld)
This is the demo code for the tutorial
[https://vaadin.com/tutorials/dependency-injection-cdi](https://vaadin.com/tutorials/dependency-injection-cdi)
## Demo running on a local Docker
If you want to run this demo on your local machine, you can try out the
docker image that is provided.
To run this type:
```bash
docker pull vaadintutorials/flow-dependency-injection-cdi
docker run -p8899:8899 --name demo vaadintutorials/flow-dependency-injection-cdi
```
After the images/container started you can try this demo with your local browser
by calling the following URL [http://localhost:8899](http://localhost:8899)
### cleaning up after trying
After you used this docker image you can clean up your system with the following commands.
```bash
docker rm demo
docker image rm vaadintutorials/flow-dependency-injection-cdi
```
### building this Docker-image by yourself
If you want to build this docker image on your machine you can use the provided **Dockerfile**
```bash
docker build -t vaadintutorials/flow-dependency-injection-cdi .
```
## Demo running on Heroku
On Heroku you find a deployed version.
[https://flow-dependency-injection-cdi.herokuapp.com/](https://flow-dependency-injection-cdi.herokuapp.com/)
## How to build this locally?
If you want to build this demo check out the repository and invoke
the command: **mvn clean package -Dvaadin-install-nodejs**
Together with this demo,
you will find some jUnit5 Selenium UI Tests based on **[Testbench](https://vaadin.com/testbench)**
To get this running you need a license, or you can request a trial from [https://vaadin.com/trial](https://vaadin.com/trial)
To activate the Testbench tests during the maven build process set the environment variable **TESTBENCH** with the value **on**
With your IDE you can run every test without setting this variable.
## How to prepare a vaadin app for Heroku
To support the Heroku pipeline we need a few preparations.
1) the app must be able to get a configured port for the http port during the start up
1) add the shade plugin to create a fat jar
1) create the file **Procfile** and add the line
``web: java -jar target/vaadin-app.jar -port $PORT```
* **web** - to activate the web profile
* **-jar** - define what fat jar must be started
* **-port** make the dynamic associated port available for the app
1) add a file **settings.xml** to configure the maven build process
Happy Coding.
