Code && Chill

Code && Chill is a Go web application for running puzzle events with:

• Time-based puzzle unlocks
• Per-user progress tracking
• Discord OAuth login
• Admin user management
• Optional Discord notifications

It stores data in BoltDB and serves a website from files in data/.

Features

• Multi-event puzzle support via YAML config
• Puzzle pages with part-by-part answer submission
• Unlock scheduling and latest-puzzle redirect
• Session management with expiration and cleanup
• Admin pages for users and puzzles
• JSON admin API for user listing and updates
• Optional HTTPS with live TLS certificate reload
• Automatic database backups on cron

Requirements

• Go 1.26+
• A Discord application (for OAuth)
• A Discord bot token (optional, for notifier integration)

Project Layout

• cmd/code-and-chill: main web server
• cmd/api: API client CLI for user admin operations
• cmd/listdb: inspect BoltDB contents
• cmd/fakeusers: seed fake users/progress for testing
• config.yaml: runtime configuration
• data/: static files, templates, and HTML pages
• db/: BoltDB storage location (default: db/cc.db)
• bak/: database backup output directory
• secret/: secret files referenced by config.yaml

Quick Start

1. Create secret files referenced by config.yaml:

secret/discord.clientsecret.txt
secret/discord.token.txt

2. Update config.yaml values for your environment:

• server.port, server.host, server.dataDir
• auth.discord.clientID, auth.discord.redirectURI, auth.discord.guildID
• notifier.baseURI and notifier.discord.channels
• puzzles.events[*].config paths

3. Run the app:

go run ./cmd/code-and-chill

To use a custom config file:

go run ./cmd/code-and-chill path/to/config.yaml

Build and Test

Build all commands into bin/:

./build.sh

Run tests:

./test.sh

Equivalent direct commands:

GOBIN=$PWD/bin go install ./...
go test -timeout 30s ./... -v

Configuration

The app uses strict YAML decoding, so unknown fields in config.yaml will fail startup.

Top-level sections:

• server
• db
• session
• auth
• notifier
• puzzles

Key settings:

• server.port: main web server port
• server.apiPort: localhost-only admin API port (0 disables separate API server)
• server.tlsCertFile + server.tlsKeyFile: enable HTTPS
• server.tlsReloadSchedule: cron schedule to reload TLS cert/key
• server.httpsRedirect: optional HTTP :80 -> HTTPS redirect
• db.backupSchedule: cron schedule for DB backups
• session.expire, session.truncate, session.cleanupSchedule: session lifecycle
• auth.discord.clientSecret: path to file containing Discord client secret
• notifier.discord.token: path to file containing Discord bot token
• puzzles.default: default event path
• puzzles.events[*].config: event configuration file path

Puzzle/Event Config

Puzzle definitions are loaded from the files referenced in puzzles.events[*].config.

Event config includes:

• event id, name
• list of puzzles with unlock times and puzzle config file paths

Puzzle config includes:

• puzzle id, path, name
• parts: markdown files for each part
• inputs: input files plus expected answers per part

Admin API

Two access patterns exist:

• Main server routing under /api/* (admin web context, requires admin account)
• Separate localhost API server on server.apiPort (direct endpoints)

Direct endpoints (no /api prefix):

• GET /users
• GET /users?name=<query>
• GET /user/{id}
• POST /user/{id}

Example update payload:

{
	"admin": true
}

API CLI

Run the helper CLI against the API port (default shown in config.yaml: 1274):

go run ./cmd/api --port 1274 user list
go run ./cmd/api --port 1274 user find "alice"
go run ./cmd/api --port 1274 user get <user-id>
go run ./cmd/api --port 1274 user update <user-id> --admin
go run ./cmd/api --port 1274 user update <user-id> --unset-admin

Database Utilities

Inspect DB content:

go run ./cmd/listdb
go run ./cmd/listdb path/to/db-file

Seed fake users/progress (development/testing):

go run ./cmd/fakeusers
go run ./cmd/fakeusers path/to/db-file

Notes

• The server expects website content and templates under server.dataDir (default: data).
• If server.host is set, host validation middleware is enabled.
• DB backups are triggered by cron and also once on process shutdown.
