Storage Backends
BBS supports two storage backends, configured in ~/.config/bbs/config.json:
SQLite (default for existing users)
{ "backend": "sqlite" }
Data stored at ~/.local/share/bbs/bbs.db.
Markdown (default for new users)
{ "backend": "markdown" }
Data stored as markdown files in ~/.local/share/bbs/. Topics in _topics.yaml, threads as individual .md files with YAML frontmatter. Human-readable and syncable via git, Syncthing, etc.
Migrating Between Backends
bbs migrate --to markdown --data-dir ~/bbs-markdown # SQLite -> Markdown
bbs migrate --to sqlite --data-dir ~/bbs-sqlite # Markdown -> SQLite
bbs migrate --to markdown --data-dir ~/bbs-markdown --force # Allow a non-empty target
Without --data-dir, the target defaults to the configured data directory, which usually contains the source backend. --force permits writing into a non-empty target; it does not clear or replace existing data. Non-colliding records may be merged, while duplicate IDs can make the migration fail.
Migration does not update config.json automatically - verify the result, then update the config manually.
Data Model
Topics → Threads → Messages (+ Attachments)
Identity format: username@source where source is cli, tui, or mcp.
Development
go run ./cmd/bbs # Run
go test ./... # Test
Architecture
- Go CLI with Cobra
- Dual storage: SQLite (modernc.org/sqlite) or Markdown (mdstore)
- TUI with Bubble Tea
- MCP server for AI agent access
