AutocompleteHandler

Base class for a Discord autocomplete handler.

Pass the command route(s) from the generated registry as the generic, the same string(s) as @AutocompleteRoute@AutocompleteRoute. Branch on the focused field with this.matchthis.match, read already-entered sibling options with this.optionsthis.options, and find which command fired with this.routethis.route.

Methods

match()
respond()

Route

One or more route keys from SlashOptionRegistrySlashOptionRegistry, e.g. 'search''search' or 'search' | 'find''search' | 'find'.

Route extends keyof SlashOptionRegistry

Route extends keyof SlashOptionRegistry

Cache

The interaction cache state, 'cached''cached' by default.

Cache extends CacheType = 'cached'

Cache extends CacheType = 'cached'

focused

The focused option for this interaction. valuevalue is always the raw partial string the user is typing, even for an integer or number option, so coerce it yourself when you need a number.

protected focused: FocusedField<Route>

protected focused: FocusedField<Route>

options

The already-entered options on this command, restricted to the kinds Discord resolves during autocomplete (string, integer, number, boolean) with every read nullable, since a sibling is partial while the user types the focused field. The focused field is on this.focusedthis.focused.

protected options: AutocompleteOptions<Route>

protected options: AutocompleteOptions<Route>

route

The firing command route, for a field whose completion differs per registered command.

protected route: Route

protected route: Route

match()

Run the arm for the focused field. An autocomplete always dispatches by which field is focused, so match is how you read it. There is no single-field shortcut the way slash/component handlers have one.

Provide one arm per autocompletable field across the registered commands, keyed by field name. Each arm receives the focused partial value and a respondrespond typed to that field's choice value. The arms must cover every autocompletable field, a missing field or an unknown key is a compile error. A focused field with no arm, only reachable from a stale-deployed command, throws at runtime.

protected async match<Ret>(
    arms: FocusedArms<Route, Ret>
): Promise<Ret>

protected async match<Ret>(
    arms: FocusedArms<Route, Ret>
): Promise<Ret>

Parameter: arms

One handler per autocompletable field, keyed by field name.

\@AutocompleteRoute('search')
class SearchAutocomplete extends AutocompleteHandler<'search'> {
    async execute() {
        await this.match({
            query: (value, respond) => respond(titles(value).map((s) => ({ name: s, value: s }))),
            tag: (value, respond) => respond(tags(value).map((s) => ({ name: s, value: s })))
        });
    }
}

\@AutocompleteRoute('search')
class SearchAutocomplete extends AutocompleteHandler<'search'> {
    async execute() {
        await this.match({
            query: (value, respond) => respond(titles(value).map((s) => ({ name: s, value: s }))),
            tag: (value, respond) => respond(tags(value).map((s) => ({ name: s, value: s })))
        });
    }
}

respond()

Send autocomplete suggestions, callback type 8. Prefer matchmatch, which restricts each field's choices to its declared type.

protected async respond(
    choices: readonly ApplicationCommandOptionChoiceData[]
): Promise<void>

    choices: readonly ApplicationCommandOptionChoiceData[]
