Function: completeFromAsync()

completeFromAsync(fn): CompletionHandler

Defined in: protocol/completions.ts:166

Escape hatch — full control over the response. Use when you need to set total/hasMore explicitly, do custom matching, or read from ctx.resolvedArguments without declaring the dependency upfront. Output is still clamped to 100 values.

complete: {
  tag: completeFromAsync(async (value, ctx) => {
    const tags = await db.tags.find({ name: { $like: `${value}%` } });
    return {
      values: tags.map(t => t.name),
      total: tags.totalCount,
      hasMore: tags.hasNext,
    };
  }),
}

Parameters

fn

(value, ctx) => string[] | CompletionResult | Promise<string[] | CompletionResult>

Returns

CompletionHandler
