This change fixes #135 which showed that trying to delete a topology
used by a scenario would result in nothing happening in the UI and a 500
error being returned by the server. We check whether a scenario still
references the topology and show an error to the user if that happens.
Fixes #135

This change updates the OpenDC web UI to show the monthly simulation
budget of the user in the user dropdown. This provides the user with a
progress bar of the used simulation minutes.
|
|
This change updates the web UI and API to support unauthenticated user
access. Such functionality is helpful when there is just a single user
that wants to try OpenDC.
|
|
This change updates the web interface in React to be compatible with the
new API written in Kotlin. Several changes have been made in the new API
to ensure consistency.
|
|
This change updates the source structure of the OpenDC frontend to
follow the page structure.
|
|
This change updates the OpenDC frontend to combine the fetching of
project relations. This means that for a single project, we make only
one additional request to retrieve all its topologies.

This change updates the OpenDC frontend to fetch schedulers and traces
using React Query, removing its dependency on Redux.
|
|
This change updates the OpenDC frontend to use React Query for fetching
and mutating project data. Previously, this state was tracked and
synchronized via Redux. Migrating to React Query greatly simplifies the
state synchronization logic necessary in the frontend.
|
|
This change splits the App container into separate pages, as a starting
point for removing much of the unnecessary state from Redux.
|
|
This change adds stricter validation of data that enters and leaves the
database. As a result, we clearly separate the database model from the
data model that the REST API exports.

This change updates the frontend codebase to move away from the Google
login and instead use Auth0 as generic Identity Provider. This allows
users to login with other accounts as well.
Since Auth0 has a free tier, users can experiment themselves with OpenDC
locally without having to pay for the login functionality. The code has
been written so that we should be able to migrate away from Auth0 once
it is not a suitable Identity Provider for OpenDC anymore.

This change updates the structure of the OpenDC frontend in order to
improve the maintainability of the frontend.
|
|
This change updates the web frontend to use Next.js instead of Create
React App (CRA). Next.js enables the possibility of rendering pages on
the server side (which reduces the time to first frame) and overall
provides a better development experience.
Future commits will try to futher optimize the implementation for
Next.js.

This change removes the socket.io websocket connection/client in favour
of the OpenDC REST API. The socket.io websocket implementation was
intended to be used for interactive and collaborative datacenter design
and exploration.
However, we do not support this functionality at the moment
(collaborative design and exploration) and having the entire API run
over this websocket connection is fragile and not standard practice.
To improve maintainability, we therefore remove the websocket
implementation in favour of the OpenDC REST API implementation using
the fetch API. If we want to implement collaboration in the future, we
will develop appropriate extensions in conjuction with the existing REST
API. For this, we should look for standard and existing implementation
of this functionality.

This change updates the workaround used to access runtime variables in
the React frontend, in order to improve the ergonimics when using the
development mode of CRA (Create React App).
|
|
This change adds support for dynamically specifying various variables
for the frontend Docker image through environmental variables.
Previously, these were embedded directly into the source code, which
requires rebuilding the entire image to change these variables.
|
|
This change updates the project structure to become flattened.
Previously, the simulator, frontend and API each lived into their own
directory.
With this change, all modules of the project live in the top-level
directory of the repository. This should improve discoverability of
modules of the project.
