• new CallbackDataBuilder<T>(prefix, ...fields): CallbackDataBuilder<T>

• Type Parameters

  • T extends string

  • prefix: string

    Prefix for the data. Use something unique across your bot.
  • Rest...fields: T[]

    Field names in the order they will be serialized.

prefix

build

• build(obj): string

• Build a callback data string

  Parameters

  • obj: Record<T, string>

    Object containing the data

  Returns string

filter

• filter<Update>(params?): UpdateFilter<Update, {
      match: Record<T, string>;
  }>

• Create a filter for this callback data.

  You can either pass an object with field names as keys and values as strings or regexes, which will be compiled to a RegExp, or a function that will be called with the parsed data. Note that the strings will be passed to RegExp directly, so you may want to escape them.

  When using a function, you can either return a boolean, or an object with field names as keys and values as strings or regexes. In the latter case, the resulting object will be matched against the parsed data the same way as if you passed it directly.

  Type Parameters

  • Update extends CallbackQuery | InlineCallbackQuery | BusinessCallbackQuery

  Parameters

  • params: Partial<Record<T, MaybeArray<string | RegExp>>> | ((upd: Update, parsed: Record<T, string>) => MaybePromise<boolean | Partial<Record<T, MaybeArray<string | RegExp>>>>) = {}

  Returns UpdateFilter<Update, {
      match: Record<T, string>;
  }>

parse

• parse(data, safe?): Record<T, string>

• Parse callback data to object

  Parameters

  • data: string

    Callback data as string
  • Optionalsafe: false

    If true, will return null instead of throwing on invalid data
