In the past we've avoided using out-of-the-box solutions for Python dependency resolution because a) they haven't been very mature and b) we've had lots of issues with version conflicts. See [[1]], [[2]] for details. Instead, we've been using a custom Python script that under-the-hood runs `pip freeze` and saves the output to `requirements.txt`. This script works well for us, but it doesn't integrate well with other tools. On the other hand [`pip-tools`](https://github.com/jazzband/pip-tools) as of 2020 seems to be well-supported by its maintainers and other tools; for instance, GitHub's automated update service [Dependabot](https://dependabot.com) supports `requirements.in` files. This commit replaces our `freeze-requirements` make command with `pip-compile`. The Digital Marketplace team have made this change and seem happy with the results.
notifications-admin
GOV.UK Notify admin application - https://www.notifications.service.gov.uk/
Features of this application
- Register and manage users
- Create and manage services
- Send batch emails and SMS by uploading a CSV
- Show history of notifications
First-time setup
1. Install Homebrew
Install Homebrew, a package manager for OSX:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
2. Make sure you're using correct language versions
Languages needed
Need to install node? Run:
brew install node
2.1. pyenv For Python version management
pyenv is a program to manage and swap between different versions of Python. To install:
brew install pyenv
And then follow the further installation instructions in https://github.com/pyenv/pyenv#installation to configure it.
2.2. n For Node version management
NPM is Node's package management tool. n is a tool for managing
different versions of Node. The following installs n and uses the long term support (LTS)
version of Node.
npm install -g n
n lts
3. Install NPM dependencies
npm install
npm rebuild node-sass
4. Install and use virtualenvwrapper (optional)
We suggest using a virtualenv to separate the python dependencies for this project from python dependencies for other projects.
Install virtualenvwrapper:
pip install virtualenvwrapper
Then follow the virtualenvwrapper installation instructions docs to configure virtualenvwrapper for your terminal.
Set up your virtualenv:
mkvirtualenv notifications-admin
If you need to specify a certain version of python you can do this using -p, for example:
mkvirtualenv -p ~/.pyenv/versions/3.6.3/bin/python notifications-admin
Activate your virtualenv:
workon notifications-admin
5. Install Python dependencies
Install dependencies and build the frontend assets:
./scripts/bootstrap.sh
Note: You may need versions of both Python 3 and Python 2 accessible to build the python dependencies. pyenv is great for that, and making both Python versions accessible can be done like so:
pyenv global 3.6.3 2.7.15
6. Create a local environment.sh file
In the root directory of the application, run:
echo "
export NOTIFY_ENVIRONMENT='development'
export FLASK_APP=application.py
export FLASK_DEBUG=1
export WERKZEUG_DEBUG_PIN=off
"> environment.sh
7. AWS credentials
Your aws credentials should be stored in a folder located at ~/.aws. Follow Amazon's instructions for storing them correctly
8. Running the application
In the root directory of the application, run:
./scripts/run_app.sh
Then visit localhost:6012
Updating application dependencies
requirements.txt file is generated from the requirements-app.txt in order to pin
versions of all nested dependencies. If requirements-app.txt has been changed (or
we want to update the unpinned nested dependencies) requirements.txt should be
regenerated with
make freeze-requirements
requirements.txt should be committed alongside requirements-app.txt changes.
Automatically rebuild the frontend assets
If you want the front end assets to re-compile on changes, leave this running in a separate terminal from the app
npm run watch
Working with static assets
When running locally static assets are served by Flask at http://localhost:6012/static/…
When running on preview, staging and production there’s a bit more to it:
