This document describes how to get a development environment configured for
modifying or contributing to EDD. This page is assuming that typical
development tools (like
git) and specific tools used by EDD (like
pre-commit) are installed already. If they are not installed, there
are separate guides for macOS and Linux pre-requisites.
Clone the repo¶
It would be difficult to start developing on EDD without the code! So step 1:
git clone https://github.com/JBEI/edd.git
Install pre-commit hooks¶
We are using
pre-commit to do some basic sanity checks on code. This
tool runs various linters and checks on every commit, and makes sure that code
is up to some minimum standards at all times. This only needs to be run once
EDD includes a script to handle creating basic initial configuration. This script will:
- Test your git configuration
- Copy sample configuration files
- Generate random passwords for use in autoconfiguring EDD’s Docker services
See the documentation inside
docker/edd/config for more information. For
development, you will most likely want to run the command as:
./bin/init-config offline --deploy=dev
While optional, this step is highly recommended, if only to enable features
like emailing yourself when errors occur, or making use of Django
features and the Django Debug Toolbar. Rename the file
settings/__init__.py, and make edits there.
Some additional changes to aid in development can be made by changing the Django settings. Add support for the Django debug toolbar in the settings directory to run EDD with a helpful debug application. This will add an expandable toolbar to every page, showing information like request headers, SQL queries run, template context, signals fired, etc.
init-config script will create a
secrets directory, containing
generated passwords and connection URLs for services. These passwords are set
in the service data volumes on first launch; to use alternate passwords or
existing services (e.g. if you already have a Postgres cluster), edit the file
prior to launching EDD.
Pull EDD’s images¶
docker-compose up will automatically pull any missing Docker images
to the host prior to launching; however, it is sometimes useful to run this
step manually. Building or pulling specific images, and tagging appropriately,
allows more control over the images used to launch EDD.
You can run EDD either on a single Docker node with
docker-compose up -d, or
use a Docker Swarm with
docker stack deploy -c [CONFIG] [STACK]. Create a
config file by running
docker-compose config and saving the output.
offline --deploy=dev will configure EDD to
launch with an ICE instance appropriate for local-only testing. An external
instance may also be configured by creating a random key like so:
openssl rand -base64 64 | tr -d '\n' > secrets/edd_ice_key
Then copy this shared secret to both the target ICE instance and EDD.
The EDD makes use of Node.js packages for managing front-end code. All dev
dependencies are contained in a Docker image, available under the tag
jbei/edd-node on Docker Hub. It is used as part of the build of the
jbei/edd-core image, to prepare front-end assets.
with third-party libraries using Webpack. The static asset files for the
frontend are bundled with the
jbei/edd-core image; however, running a full
Docker build following any change to the TypeScript code, will be inefficient.
To avoid this, follow these configuration steps to get changed TypeScript
deployed to a running EDD without a full build.
This will typically be
docker-compose up -d, or
docker stack deploy. The
compose file used to launch should have an override to load code in from the
host to a volume mounted at
/code. This should already be in place when using
--deploy=dev flag to
Edit and Compile Typescript¶
bin/local_typescript_shell.sh script to launch a container for the
EDD TypeScript environment. Inside the TypeScript container shell, execute
npm run local to do a one-time local build, or
npm run watch to monitor
changes and run incremental builds on save.
Refresh static files in EDD¶
Once static files are compiled, use the
refresh_static.sh command in an EDD
container built in dev mode. This command will copy any changed static files so
they can be served, and update the internal Django settings used by EDD to
identify the currently active static files.
