Private Relay

Repo Size

Private Relay provides generated email addresses to use in place of personal
email addresses.

Recipients will still receive emails, but Private Relay keeps their personal
email address from being harvested,
and then bought, sold, traded, or combined
with other data to personally identify, track, and/or target
them.

Development

Please refer to our coding standards for code styles, naming conventions and other methodologies.

Requirements

python 3.12 (we recommend venv)
PostgreSQL - even if you are using sqlite for development, requirements.txt installs
psycopg2 which requires libpq and Python header files.
The following should work:
- On Windows
- On Ubuntu: sudo apt install postgresql libpq-dev python3-dev
- On OSX: brew install postgresql libpq
- On Fedora: sudo dnf install libpq-devel python3-devel
SES if you want to send real emails
Volta – Sets up the right versions of Node and npm, needed to compile the front-end

Install and Run the Site Locally

Clone and change to the directory:

git clone --recurse-submodules https://github.com/mozilla/fx-private-relay.git
cd fx-private-relay

Create and activate a virtual environment:

Unix based systems:
```
virtualenv env
source env/bin/activate
```
Windows:
```
python -m venv env
source env/Scripts/activate
```
If you are not using Git Bash on Windows, instead of typing source env/Scripts/activate, type .\env\Scripts\activate.

Note: If you’re running on Windows and get an error message stating that executing scripts are disabled on your computer, go into the Windows powershell and type Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted, then try again.
Install Python and Node requirements:
```
pip install -r requirements.txt
```
```
cd frontend
npm install
cd ../
```
Note: If you’re running on Windows, you may run into an issue with usage of environment variables in npm scripts. You can force npm to use git-bash: npm config set script-shell "C:\\Program Files\\Git\\bin\\bash.exe". This the default location, your install may be different.
Copy .env file for
decouple config:
```
cp .env-dist .env
```

Add a SECRET_KEY value to .env:

SECRET_KEY=secret-key-should-be-different-for-every-install

Migrate DB:
```
python manage.py migrate
```
Create superuser:
```
python manage.py createsuperuser
```
Run the backend:
```
python manage.py runserver
```
and in a different terminal, build the frontend:
```
cd frontend
npm run watch
```

Working with translations

The following docs will get you started with development, include creating new
strings to translate. See Translation and Localization
for general information on Relay localization.

Getting the latest translations

We use a git submodule
for translated message files. The --recurse-submodules step of installation
should bring the message files into your working directory already, but you may
want also want to update the translations after install. The easiest way to do
that is:

git submodule update --remote

To update the submodule automatically when running git pull or other commands:

git config --global submodule.recurse true

Add/update messages for translation

The privaterelay/locales directory is a git repository like any other, so to
make changes to the messages:

Make whatever changes you need in privaterelay/locales/en as you work.
cd privaterelay/locales/en
git branch message-updates-yyyymmdd
git push -u origin message-updates-yyyymmdd

You can then open a pull request from the message-updates-yyyymmdd branch to
the l10n repo main branch.

If you’re not yet ready to submit some strings for translation, you can
tentatively add them to frontend/pendingTranslations.ftl. Strings in that file
will show up until strings with the same ID are added to the l10n repository.

Similarly, there is a pending_locales/pending.ftl where temporary backend locales strings can be stored. Once the strings from the pull request in the l10n repo has been merged into the Relay repo, these respective strings need to be removed from pending_locales/pending.ftl to avoid failing CircleCI tests.

Commit translations for release

To commit updates to the app’s translations (e.g., before a release), we need
to commit this submodule update. So, if the updated translations are ready to
be committed into the app, you can git add the submodule just like any other
file:

git add privaterelay/locales

You can then commit and push to set the app repository to the updated version
of the translations submodule:

git push

An automated process updates the submodule daily, bringing in any new changes
and translations from the Localization Team.

Recommended: Enable Mozilla Accounts authentication

To enable Mozilla Accounts authentication on your local server, you can use the
“Firefox Private Relay local dev” OAuth app on accounts.stage.mozaws.net.

To do so:

Set ADMIN_ENABLED=True in your .env file
Shutdown the server if running, and add the admin tables with:
```
python manage.py migrate
```
Run the server, now with /admin endpoints:
```
python manage.py runserver
```
Go to the django admin page to change the default
site.
Change example.com to 127.0.0.1:8000 and click Save.
Go to the django-allauth social app admin
page, sign in with the
superuser account you created above, and add a social app for Firefox Accounts:

Field	Value
Provider	Mozilla Accounts
Name	`accounts.stage.mozaws.net`
Client id	`9ebfe2c2f9ea3c58`
Secret key	Request this from `#fx-private-relay-eng` Slack channel
Sites	`127.0.0.1:8000` -> Chosen sites

Now you can sign into http://127.0.0.1:8000/ with an
FxA.

⚠️ Remember that you’ll need to use an account on https://accounts.stage.mozaws.net/, not
the production site, accounts.firefox.com.

Optional: Install and run the add-on locally

Note: The add-on is located in a separate repo. See it for additional information on getting started.

The add-on adds Firefox UI to generate and auto-fill email addresses across the web. Running the add-on locally allows it to communicate with your local server (127.0.0.1:8000) instead of the production server (relay.firefox.com).

Optional: Run a development server to compile the frontend

npm run watch watches the frontend/src directory and builds the frontend
when it detects changes. However, creating a production build is just time-consuming
enough to interrupt your development flow. It is therefore also possible to run the
front-end on a separate server that only recompiles changed modules, and does not
apply production optimizations. To do so, instead of npm run watch, run
npm run dev.

The frontend is now available at http://localhost:3000. Keep in mind that this
does make your local development environment less similar to production; in
particular, authentication is normally bound to the backend server, and thus
needs to be simulated when running the frontend on a separate server. If
you make any changes related to authentication, make sure to test them using
npm run watch as well.

Optional: Enable Premium Features

Note: Premium features are automatically enabled for any user with an email address ending in
mozilla.com, getpocket.com, or mozillafoundation.org (see PREMIUM_DOMAINS in
emails/models.py). To mimic the customer’s experience, it is recommended to follow the below
procedure.

To enable the premium Relay features, we integrate with the FXA Subscription
Platform.
At a high level, to set up Relay premium subscription, we:

Enable Mozilla Accounts Authentication as described above.
Create a product & price in our Stripe dashboard.
(Ask in #subscription-platform Slack channel to get access to our Stripe dashboard.)
Link free users of Relay to the appropriate SubPlat purchase flow.
Check users’ FXA profile json for a subscriptions field to see if they can
access a premium, subscription-only feature.

In detail:

Enable Mozilla Accounts Authentication as described above.
Go to our Stripe dashboard.
(Ask in #subscription-platform Slack channel to get access to our Stripe dashboard.)
Create a new product in Stripe.
Add all required product: metadata.
- Note: each piece of this metadata must have a product: prefix. So, for
  example, webIconURL must be entered as product:webIconURL.
Add capabilities: metadata.
- Note: Each piece of this metadata must have a format like
  capabilities:<fxa oauth client ID>, and the value is a free-form string
  to describe the “capability” that purchasing the subscription gives to the
  user. E.g., capabilities:9ebfe2c2f9ea3c58 with value of premium-relay.
Set some env vars with values from the above steps:

Var	Value
`FXA_SUBSCRIPTIONS_URL`	`https://accounts.stage.mozaws.net/subscriptions`
`PERIODICAL_PREMIUM_PROD_ID`	`prod_KEq0LXqs7vysQT` (from Stripe)
`PREMIUM_PLAN_ID_US_MONTHLY`	`price_1LiMjeKb9q6OnNsLzwixHuRz` (from Stripe)
`PREMIUM_PLAN_ID_US_YEARLY`	`price_1LiMlBKb9q6OnNsL7tvrtI7y` (from Stripe)
`PHONE_PROD_ID`	`prod_LviM2I0paxH1DZ` (from Stripe)
`PHONE_PLAN_ID_US_MONTHLY`	`price_1LDqw3Kb9q6OnNsL6XIDst28` (from Stripe)
`PHONE_PLAN_ID_US_YEARLY`	`price_1Lhd35Kb9q6OnNsL9bAxjUGq` (from Stripe)
`BUNDLE_PROD_ID`	`prod_MQ9Zf1cyI81XS2` (from Stripe)
`BUNDLE_PLAN_ID_US`	`price_1Lwp7uKb9q6OnNsLQYzpzUs5` (from Stripe)
`SUBSCRIPTIONS_WITH_UNLIMITED`	`"premium-relay"` (match the `capabilities` value you used in Stripe)
`SUBSCRIPTIONS_WITH_PHONE`	`"relay-phones"` (match the `capabilities` value you used in Stripe)

Optional: Debugging JavaScript bundle sizes

In frontend/, set ANALYZE=true when running npm run build to generate a
report detailing which modules are taking up most of the bundle size. A report
will be generated for both the client and server part of the frontend, but since
we only use the client, we’re really only interested in that. The reports will
automatically open in your browser, and can also be found in
/frontend/.next/analyze/.

ANALYZE=true npm run build

Test Premium

There is a comprehensive doc of test
cases for purchasing premium Relay.

You can use Stripe’s test credit card details for payment.

The phone features are further protected by a waffle flag phones. In stage,
you’ll need an SRE to add the flag to your test user. On the development
server, a developer can add the flag.

Production Environments

Requirements

In addition to the requirements for dev, production environments should use:

PostgreSQL-compatible DB

Environment Variables

Production environments should also set some additional environment variables:

DATABASE_URL=postgresql://<username>:<password>@<host>:<port>/<database>
DJANGO_SECURE_HSTS_SECONDS=15768000
DJANGO_SECURE_SSL_REDIRECT=True
