SQL Explorer backend
This is the backend for the SQL Explorer application.
The previous README file can be found here. You'll notably find there some basic information on the API endpoints.
This is an Express application, that connects to a PostgreSQL database (that contains the application data), along with several databases on an SQL Server (each of which represents an assignment subject).
The app is composed primarily of a single file server.js where almost all the routes and logic is written, with the exception of the LTI stuff (see below).
The front-end for this app is available on its own repository.
LTI
This application is compatible with the LTI standard, under its v1.1 version.
All LTI related code is found in the lti folder.
Scripts
The package.json file lists the available script such as the dev script and those for deploying the app.
Deployment
The deployment is done using the bash-deploy plugin and the two files sqlexplorer.conf and staging-sqlexplorer.conf
The ecosystem.config.js file is used by PM2 on the servers
Check that everything's good
When deployed, you can make some very simple tests on the webapp to see if everything's all right:
- Go to https://sqlexplorer.heig-vd.ch` and check that you see something
- Write any SQL query for the displayed database and check that it returns something
- Write any wrong query and check that the error displayed is not something like
Internal Server Error 505... - Go to the admin page and check that the you can naviguate around
- You could also try to create a new assignment (though you'll need to remove it from the database afterward)
