Concepts

These pages explain the building blocks of DJS Commands — what they do, when to reach for them, and how they compose. Read them in order on your first pass; jump in topically afterwards.

Commands

Defining commands with defineCommand. Naming, options, subcommands, contexts.

Validators

Pre-handler checks: roles, channels, custom predicates. Composable, async-friendly.

Cooldowns

Per-user, per-guild, per-command rate limiting backed by your storage adapter.

Plugins

Cross-cutting hooks: logging, metrics, custom interaction types, lifecycle wrappers.

Storage

The adapter interface that backs cooldowns, prefixes, and user state. Bring your own DB.

Components V2

First-class JSX for the new Discord component model — buttons, selects, modals, layouts.

How the pieces fit

Discord interaction
       ↓
createCommandHandler (subscribes to events)
       ↓
Dispatcher (looks up command by name)
       ↓
Validators (gate the call)
       ↓
Plugins (wrap the call — before/after)
       ↓
command.run({ interaction, ...context })
       ↓
Components V2 reply (optional)

Storage sits orthogonal to that pipeline — anything that needs to remember state across calls (cooldowns, per-guild prefixes, user preferences) reads and writes through the adapter you provide.
