This project contains the source code for a Python webserver that implements CRUD operations on the topology institutions Postgres database, as well as an Angular frontend to that API. The frontend and backend are designed to be run in two separate containers, using Apache to reverse proxy requests to the appropriate destination. Read operations to the API are unauthenticated, while write operations are authenticated via OIDC.
The institutions-api/ folder contains a FastAPI application
that implements a CRUD API for reading and modifying the topology institutions Postgres database.
institutions-api/app.py contains the application entrypoint and endpoint definitions,
while institutions-api/db/ contains implementations of database logic.
A docker image for the backend can be built via
$ docker build -t topology-institutions-api -f institutions-api.Dockerfile .
The application is hosted behind Apache to facilitate OIDC authentication. FastAPI
implements ASGI rather than WSGI, so the shim wsgi.py is provided to enable running the
application behind Apache.
The institutions-ui/ folder contains an Angular application with a viewer and editor for the
institutions list.
The docker image for the frontend can be built via
$ docker build -t topology-institutions-ui -f institutions-ui.Dockerfile .
The Apache configuration for the backend is expected to contain rules for proxying requests to the ui/
route prefix to the frontend's deployment.
Running the following will build and deploy this image in a location that it can be pulled from Tiger.
