Static guard

  • Generates optional middleware based on a predicate that only operates on ctx.update.

    Example:

    import { Composer, Update } from 'telegraf'

    const predicate = (u): u is Update.MessageUpdate => 'message' in u
    const middleware = Composer.guard(predicate, (ctx) => {
    const message = ctx.update.message
    })

    Note that Composer.mount('message') is preferred over this.

    see

    Composer.optional for a more generic version of this method that allows the predicate to operate on ctx itself

    Type parameters

    Parameters

    • guardFn: (u: Update) => u is U

      predicate to decide whether to run the middleware based on the ctx.update object

        • (u: Update): u is U
        • Parameters

          • u: Update

          Returns u is U

    • Rest ...fns: NonemptyReadonlyArray<Middleware<NarrowedContext<C, U>>>

      middleware to run if the predicate returns true

    Returns MiddlewareFn<C>
