Finatra Hello World Heroku Example Application

If you're in master or a feature branch

  • Development from master or feature branches is not currently supported for this example. Please switch to a release branch and see the instructions below.

If you're in a tagged release branch (e.g. finatra-2.2.0)

Run the server on Heroku

Copy the hello-world-heroku directory contents (minus the .git directory) to another location locally.

$ cp -R hello-world-heroku ~/finatra-hello-world

Initialize a git repository in the new directory location:

$ cd ~/finatra-hello-world
$ git init
Initialized empty Git repository in ~/finatra-hello-world/.git/

Create a .gitignore file (notice the newlines):

$ echo ".DS_Store
classes/
target/
sbt-launch.jar" > .gitignore

Commit all the files to master:

$ git add .
$ git commit -m "Initial commit."

Compile and stage the application:

$ sbt compile stage

Make sure you have the Heroku Toolbelt installed.

Create a new app in Heroku:

$ heroku create
Creating nameless-lake-8055 in organization heroku... done, stack is cedar-14
http://nameless-lake-8055.herokuapp.com/ | https://git.heroku.com/nameless-lake-8055.git
Git remote heroku added

Then deploy the example application to Heroku:

$ git push heroku master
Counting objects: 480, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (376/376), done.
Writing objects: 100% (480/480), 27.68 MiB | 16.24 MiB/s, done.
Total 480 (delta 101), reused 0 (delta 0)
remote: Compressing source files... done.
remote: Building source:
	...

You can then open the application in a browser with heroku open, e.g.:

$ heroku open hi?name=foo

Run the example locally with the Heroku Toolbelt

See the Heroku documentation on running an app locally with Foreman.

The app will now be running at http://localhost:5000/hi?name=foo. Ctrl-C to exit.
