FitTrackee/docsrc/source/installation.rst

Installation
############

This application is written in Python (API) and Typescript (client):

- API:
    - Flask
    - `gpxpy <https://github.com/tkrajina/gpxpy>`_ to parse gpx files
    - `staticmap <https://github.com/komoot/staticmap>`_ to generate a static map image from gpx coordinates
    - `python-forecast.io <https://github.com/ZeevG/python-forecast.io>`_ to fetch weather data from `Dark Sky <https://darksky.net>`__ (former forecast.io)
    - `dramatiq <https://flask-dramatiq.readthedocs.io/en/latest/>`_ for task queue
- Client:
    - Vue3/Vuex
    - `Leaflet <https://leafletjs.com/>`__ to display map
    - `Chart.js <https://www.chartjs.org/>`__ to display charts with elevation and speed

| Logo, some sports and weather icons are made by `Freepik <https://www.freepik.com/>`__ from `www.flaticon.com <https://www.flaticon.com/>`__.
| FitTrackee also uses icons from `Fork Awesome <https://forkaweso.me>`__.

.. envvar:: STATICMAP_SUBDOMAINS 🆕

    .. versionadded:: 0.6.10

.. envvar:: DEFAULT_STATICMAP

    .. versionadded:: 0.4.9

    | If `True`, it keeps using default tile server to generate static maps (Komoot.de tile server).
    | Otherwise, it uses the tile server set in `TILE_SERVER_URL <installation.html#envvar-TILE_SERVER_URL>`__.

    .. versionchanged:: 0.6.10

    | This variable is now case-insensitive.
    | If `False`, depending on tile server, `subdomains <installation.html#envvar-STATICMAP_SUBDOMAINS>`__ may be mandatory.

    **FitTrackee** API URL, only needed in dev environment.



Emails
^^^^^^
.. versionadded:: 0.3.0

To send emails, a valid ``EMAIL_URL`` must be provided:

- with an unencrypted SMTP server: ``smtp://username:password@smtp.example.com:25``
- with SSL: ``smtp://username:password@smtp.example.com:465/?ssl=True``
- with STARTTLS: ``smtp://username:password@smtp.example.com:587/?tls=True``

.. warning::
    | - If the email URL is invalid, the application may not start.
    | - Sending emails with Office365 may not work if SMTP auth is disabled.

.. versionchanged:: 0.5.3

| Credentials can be omitted: ``smtp://smtp.example.com:25``.
| If ``:<port>`` is omitted, the port defaults to 25.

.. warning::
     | Since 0.6.0, newly created accounts must be confirmed (an email with confirmation instructions is sent after registration).

Emails sent by FitTrackee are:

- account confirmation instructions
- password reset request
- email change (to old and new email adresses)
- password change

.. versionchanged:: 0.6.5

| For single-user instance, it is possible to disable email sending with an empty ``EMAIL_URL`` (in this case, no need to start dramatiq workers).
| A `CLI <cli.html#ftcli-users-update>`__ is available to activate account and modify email and password.


Map tile server
^^^^^^^^^^^^^^^
.. versionadded:: 0.4.0

Default tile server is now **OpenStreetMap**'s standard tile layer (if environment variables are not initialized).
The tile server can be changed by updating ``TILE_SERVER_URL`` and ``MAP_ATTRIBUTION`` variables (`list of tile servers <https://wiki.openstreetmap.org/wiki/Tile_servers>`__).

To keep using **ThunderForest Outdoors**, the configuration is:

- ``TILE_SERVER_URL=https://{s}.tile.thunderforest.com/outdoors/{z}/{x}/{y}.png?apikey=XXXX`` where **XXXX** is **ThunderForest** API key
- ``MAP_ATTRIBUTION=&copy; <a href="http://www.thunderforest.com/">Thunderforest</a>, &copy; <a href="http://www.openstreetmap.org/copyright">OpenStreetMap</a> contributors``

.. note::
    | Check the terms of service of tile provider for map attribution


.. versionchanged:: 0.6.10

Since the tile server can be used for static map generation, some servers require a subdomain.

For instance, to set OSM France tile server, the expected values are:

- ``TILE_SERVER_URL=https://{s}.tile.openstreetmap.fr/osmfr/{z}/{x}/{y}.png``
- ``MAP_ATTRIBUTION=fond de carte par <a href="http://www.openstreetmap.fr/mentions-legales/" target="_blank" rel="nofollow noopener">OpenStreetMap France</a>, sous&nbsp;<a href="http://creativecommons.org/licenses/by-sa/2.0/fr/" target="_blank" rel="nofollow noopener">licence CC BY-SA</a>``
- ``STATICMAP_SUBDOMAINS=a,b,c``

The subdomain will be chosen randomly.
