SAUCE

The SCCS Account and User Control Engine, or SAUCE, is the central dashboard for SCCS services. The project replaces GUTS (the Grand Unified Task System) and SCCS's previous static homepage.

Features

• Cool landing page
• On-the-fly generation of newsfeed posts and public-facing documentation from Markdown files (somewhat similar to Jekyll)
• Login using our LDAP server
• Integrations with our other services:
  • Account creation
  • Mailing lists
  • Minecraft server
• Secure password hashing with Argon2
• Admin dashboard with request management and user database search
• Seperate agent processes to perform some tasks requiring root access
• Notification emails for users and admins

Development

The backend is written in TypeScript on top of Express.js and MongoDB. Pages are rendered from Pug templates with some JavaScript logic, though since the frontend JS/CSS is prebuilt with Webpack and served statically, using other languages on the backend would be fairly trivial. It uses Bootstrap 5 for most styling, with some customizations applied using SCSS.

To install git hooks to run Prettier and ESLint before each commit, run npm run installHooks.

Docker

Start containers for development:

bin/dev.sh

A mock LDAP server is included with two users: testadmin and testuser (both with password test). For development, the source directories in the container are mounted to their local counterparts, so code changes will be reflected in the container without rebuilds. (You will need to wait for webpack, etc. to finish building in the container when changing static assets.)

To run automated integration tests:

bin/test.sh

For production, certain secrets and config should be specified in a docker-compose.override.yml file. An example file is provided in docker-compose.override.yml.example. Also, the agents need to be running somewhere on the system (see READMEs in user-agent/ and mc-agent/). Then, launch the backend:

docker-compose up

Local Development

This is not recommended as it requires spinning up your own instance of Mongo, LDAP, the agents, etc. However, it's provided here for completeness.

Installation:

npm install
# only necessary if you are using the local agent
npm run install:user-agent
npm run install:mc-agent

Build static web files and compile TypeScript:

npm run build

Run the server:

npm start

Or in production:

node build/src/index.js

When running locally, the app requires various credentials for other services (LDAP, Mailman, SMTP...) which can be configured in a .env file. An example .env is provided in .env.example. When running Dockerized, the environment variables are provided through the docker-compose.override.yml.

Folder Structure

• /user-agent: A seperate, self-contained service to run user management tasks that require root access to the server.
• /mc-agent: A seperate, self-contained service to run minecraft server management tasks that require root access to the server.
• /browserTests: Selenium WebDriver tests that are run through Docker.
• /emailTemplates: Basic plaintext templates for emails. Email templating uses this one-liner, so variable incorporation is just ${templateVariable}.
• /views: Pug templates for the web interface
  • /views/include: Common code for all templates (e.g. sauce-container to add headers and footers)
• /src: Server code; root folder contains index.ts with main configuration
  • /src/controllers: Business logic and controllers called from routes
  • /src/error: HTTP and application error handling
  • /src/functions: Functions that will be run on a delayed basis (e.g. createUser); contains business logic to actually do those tasks.
  • /src/routes: HTTP routing code for app functions
  • /src/integration: Definitions and config for all external services (MongoDB, LDAP, SMTP server, etc.)
  • /src/util: Misc utilities
• /webStatic: Client-side static code (SCSS and JS). This is its own Node project built with Webpack.
