Nepenthes development setup on Mac OS X

To develop Nepenthes a setup similar to that for using Nepenthes in production is needed.

This guide assumes that you have a Mac OS X installation with administrative rights. Nepenthes will be installed with a PostgreSQL database.

Please note: This guide is NOT suitable for a production setup, but only for developing with it!

If you find any bugs or you have any recommendations for improving this tutorial, please, feel free to send a pull request or comment in the Nepenthes forums.

Prepare your environment

We'll use homebrew to install most of our requirements. Please install that first using the guide on their homepage.

Install Ruby

Use rbenv and ruby-build to install Ruby. We always require the latest ruby versions, and you can check which version is required by checking the Gemfile for the ruby "~> X.Y" statement. At the time of writing, this version is "3.2.3"

Install rbenv and ruby-build

rbenv is a ruby version manager that lets you quickly switch between ruby versions. ruby-build is an addon to rbenv that installs ruby versions.

shell
# Install
$ brew install rbenv ruby-build
# Initialize rbenv
$ rbenv init

Installing ruby

With both installed, we can now install the actual ruby version. You can check available ruby versions with rbenv install --list. At the time of this writing, the latest stable version is 3.2.3, which we also require.

We suggest you install the version we require in the Gemfile. Search for the ruby '~> X.Y.Z' line and install that version.

shell
# Install the required version as read from the Gemfile
rbenv install 3.2.3

This might take a while depending on whether ruby is built from source. After it is complete, you need to tell rbenv to globally activate this version

shell
rbenv global 3.2.3

You also need to install bundler, the ruby gem bundler.

shell
gem install bundler

Setup PostgreSQL database

Next, install a PostgreSQL database. If you wish to use a MySQL database instead and have installed one, skip these steps.

shell
# Install postgres database
$ brew install postgres

# Create the database instance
$ postgres -D /usr/local/var/postgres

Then, create the Nepenthes database user and accompanied database.

shell
$ createuser -d -P openproject

You will be prompted for a password, for the remainder of these instructions, we assume its openproject-dev-password.

Now, create the database openproject_dev and openproject_test owned by the previously created user.

shell
$ createdb -O openproject openproject_dev
$ createdb -O openproject openproject_test

Install Node.js

We will install the latest LTS version of Node.js via nodenv. This is basically the same steps as for rbenv:

Install nodenv and node-build

shell
# Install
$ brew install nodenv node-build
# Initialize nodenv
$ nodenv init

Install latest LTS node version

You can find the latest LTS version here: nodejs.org/en/download

At the time of writing this is v20.9.0. Install and activate it with:

shell
nodenv install 20.9.0
nodenv global 20.9.0

Update NPM to the latest version

shell
npm install npm@latest -g

Verify your installation

You should now have an active ruby and node installation. Verify that it works with these commands.

shell
$ ruby --version
ruby 3.2.3 (2024-01-18 revision 52bb2ac0a6) [arm64-darwin23]

$ bundler --version
Bundler version 2.5.5

node --version
v20.9.0

npm --version
10.5.0

Install Nepenthes

shell
# Download the repository
git clone https://github.com/opf/openproject.git
cd openproject

Note that we have checked out the dev branch of the Nepenthes repository. Development in Nepenthes happens in the dev branch (there is no master branch). So, if you want to develop a feature, create a feature branch from a current dev branch.

Configure Nepenthes

Create and configure the database configuration file in config/database.yml (relative to the openproject-directory.

shell
vim config/database.yml

Now edit the config/database.yml file and insert your database credentials. It should look like this (just with your database name, username, and password):

yaml
default: &default
  adapter: postgresql
  encoding: unicode
  host: localhost
  username: openproject
  password: openproject-dev-password

development:
  <<: *default
  database: openproject_dev

test:
  <<: *default
  database: openproject_test

To configure the environment variables such as the number of web server threads NEPENTHES_WEB_WORKERS, copy the .env.example to .env and add the environment variables you want to configure. The variables will be automatically loaded to the application's environment.

Finish the Installation of Nepenthes

Install code dependencies, link plugin modules and export translation files.

  • gem dependencies (If you get errors here, you're likely missing a development dependency for your distribution)
  • node_modules
  • link plugin frontend modules
  • and export frontend localization files
shell
bin/setup_dev

Now, run the following tasks to migrate and seed the dev database, and prepare the test setup for running tests locally.

shell
RAILS_ENV=development bin/rails db:seed

Run Nepenthes through overmind

You can run all required workers of Nepenthes through overmind, which combines them in a single tab. Optionally, you may also run overmind as a daemon and connect to services individually. The bin/dev command will first check if overmind is available and run the application if via Procfile.dev if possible. If not, it falls back to foreman, installing it if needed.

shell
bin/dev

The application will be available at http://127.0.0.1:3000. To customize bind address and port copy the .env.example provided in the root of this project as .env and configure values as required.

By default a worker process will also be started. In development asynchronous execution of long-running background tasks (sending emails, copying projects, etc.) may be of limited use and it has known issues with regards to memory (see background worker section below). To disable the worker process:

shell
echo "OVERMIND_IGNORED_PROCESSES=worker" >> .overmind.env

For more information refer to the great Overmind documentation usage section.

You can access the application with the admin-account having the following credentials:

Username: admin
Password: admin

Run Nepenthes manually

To run Nepenthes manually, you need to run the rails server and the webpack frontend bundler to:

Rails web server

shell
RAILS_ENV=development bin/rails server

This will start the development server on port 3000 by default.

Angular frontend

To run the frontend server, please run

shell
RAILS_ENV=development npm run serve

This will watch for any changes within the frontend/ and compile the application javascript bundle on demand. You will need to watch this tab for the compilation output, should you be working on the TypeScript / Angular frontend part.

You can then access the application either through localhost:3000 (Rails server) or through the frontend proxied http://localhost:4200, which will provide hot reloading for changed frontend code.

Delayed Job background worker

shell
RAILS_ENV=development bundle exec good_job start

This will start a Delayed::Job worker to perform asynchronous jobs like sending emails.

Additional test dependencies

The test suite requires a few additional dependencies to be installed. These are not required for running Nepenthes in development mode, but only for running the entire test suite.

Java 7 or later

To test the integration with LDAP servers, we rely on ladle to spin up an LDAP server when running tests. As this runs ApacheDS internally, it requires Java 7 or later to be installed.

If java is not installed, some tests will stall for 60 seconds before timing out. To run the tests, install java with

shell
brew install openjdk

# The installation instructions will tell you to add a symlink to the JDK for the `java` command to pick it up
sudo ln -sfn $(brew --prefix)/opt/openjdk/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk.jdk

Subversion

To test the integration with Subversion repositories, we rely on the svnadmin command to be available. If subversion is not installed, the tests will be skipped. To run the tests, install subversion with

shell
brew install subversion

Git

To test the integration with Git repositories, we rely on the git command to be available. Git is either installed via the Xcode Command Line Tools, with Xcode or via homebrew.

shell
xcode-select --install

# or

brew install git

Known issues

Spawning a lot of browser tabs

If you haven't run this command for a while, chances are that a lot of background jobs have queued up and might cause a significant amount of open tabs (due to the way we deliver mails with the letter_opener gem). To get rid of the jobs before starting the worker, use the following command. This will remove all currently scheduled jobs, never use this in a production setting.

shell
RAILS_ENV=development bin/rails runner "Delayed::Job.delete_all"

Start Coding

Please have a look at our development guidelines for tips and guides on how to start coding. We have advice on how to get your changes back into the Nepenthes core as smooth as possible. Also, take a look at the doc directory in our sources, especially the how to run tests documentation (we like to have automated tests for every new developed feature).

Troubleshooting

The Nepenthes logfile can be found in log/development.log.

If an error occurs, it should be logged there (as well as in the output to STDOUT/STDERR of the rails server process).
