Rename accounts to users to be consistent with the new naming scheme
where account only referes to the logged in user of the session and
implement live updates of users via a user store which listens for
updates from the event stream.
Rename and refactor the types passed over the API to be based on an
entity that's either living or a tombstone. A living entity has a
deleted property that's either undefined or false, while a tombstone
has a deleted property set to true. All entities have a numeric id
and an updatedAt timestamp.
To sync entities, an array of replacements are passed around. Living
entities are replaced with tombstones when they're deleted. And
tombstones are replaced with living entities when restored.
Start the work of clearly distingushing client side types, server side
types and types shared over the API by renaming "AccountSession" and
"Session" names used on the server to "ServerSession".
Putting secrets into environment variables is problematic due to them
being inherited by sub-processes, the ease as which these can be
leaked in logs, and the lack of support for loading secrets into
environment variables by systems such as systemd and docker.
Change the loading of secrets to be done by loading the content of a
file specified by an environment variable.
If a cookie is signed for one purpose, but the server also uses a
differently named signed cookie name for another purpose, then it's
possible for a malicious client to substitute the value of one signed
cookie with the value of another and have it pass the signature check.
Include the name of the cookie when computing the signature so that no
cookies signed for example for "user_session" can be used as a value for
a hypothetical "admin_session" cookie.
Set a max age for the session cookie to prevent it from expiring when
the browser is closed. To prevent the age limit from being being
reached the session cookie is refreshed every time the session is
loaded. This should fix login being lost when the browser is stopped.
If a user logs out from a device the expectation should be that device
no longer having any association with the user's account. Any existing
push notifications should thefore be removed on server. For this reason
tie push notifications to a session, and remove them when the session is
deleted.
Provide a basic account system with login and server side session store
identified by a cookie. Upon successful login a signed session cookie
is set by the server with the session stored on the server identifying
which account it is logged in as. The client uses a shared useFetch on
the session endpoint to identify if it's logged in and which account it
is logged in as, and refreshes this when loggin in or out.
Provide a convenient wrapper for setting SHA-256 HMAC signed cookies and
retreiving them with the signature validated. The secret key is
configured in the NUXT_COOKIE_SECRET_KEY environment variable.
