MenuRange ​

ref / menu / MenuRange

A menu range is a two-dimensional array of menu buttons.

This array is a part of the total two-dimensional array of menu buttons. This is mostly useful if you want to dynamically generate the structure of the menu on the fly.

Type Parameters ​

C ​

ts
C extends Context

Properties ​

[ops] ​

ts
[ops]: MaybeDynamicRange<C>[];

Internal list of range generator functions

Methods ​

addRange ​

ts
addRange(...range: MaybeDynamicRange<C>[]);

This method is used internally whenever a new range is added.

Source

add ​

ts
add(...btns: MenuButton<C>[]);

This method is used internally whenever new buttons are added. Adds the buttons to the current row.

Source

row ​

ts
row();

Adds a ‘line break’. Call this method to make sure that the next added buttons will be on a new row.

Source

url ​

ts
url(text: MaybeDynamicString<C>, url: MaybeDynamicString<C>);

Adds a new URL button. Telegram clients will open the provided URL when the button is pressed. Note that they will not notify your bot when that happens, so you cannot react to this button.

Source

text ​

ts
// Overload 1
text(text: MaybeDynamicString<C>, ...middleware: MenuMiddleware<C>[]): this;
// Overload 2
text(text: TextAndPayload<C>, ...middleware: MenuMiddleware<C & { match: string }>[]): this;
// Overload 3
text(text: MaybePayloadString<C>, ...middleware: MenuMiddleware<C>[]): this;

Adds a new text button. You may pass any number of listeners. They will be called when the button is pressed.

ts
menu.text('Hit me!', ctx => ctx.reply('Ouch!'))

If you pass several listeners, make sure that you understand what middleware is.

You can also use this method to register a button that depends on the current context.

ts
function greetInstruction(ctx: Context): string {
  const username = ctx.from?.first_name
  return `Greet ${username ?? 'me'}!`,
}

const menu = new Menu('my-menu')
  .text(greetInstruction, ctx => ctx.reply("I'm too shy."))
bot.use(menu)

// This will send a menu with one text button, and the text has the name
// of the user that the bot is replying to.
bot.on('message', ctx => ctx.reply('What shall I do?', { reply_markup: menu }))

If you base the text on session data, you can easily create a settings panel with toggle buttons.

ts
// Button will toggle between 'Yes' and 'No' when pressed
menu.text(ctx => ctx.session.flag ? 'Yes' : 'No', async ctx => {
  ctx.session.flag = !ctx.session.flag
  await ctx.menu.update()
})

webApp ​

ts
webApp(text: MaybeDynamicString<C>, url: string);

Adds a new web app button, confer https://core.telegram.org/bots/webapps

Source

login ​

ts
login(text: MaybeDynamicString<C>, loginUrl: string | LoginUrl);

Adds a new login button. This can be used as a replacement for the Telegram Login Widget. You must specify an HTTPS URL used to automatically authorize the user.

Source

switchInline ​

ts
switchInline(text: MaybeDynamicString<C>, query: string);

Adds a new inline query button. Telegram clients will let the user pick a chat when this button is pressed. This will start an inline query. The selected chat will be prefilled with the name of your bot. You may provide a text that is specified along with it.

Your bot will in turn receive updates for inline queries. You can listen to inline query updates like this:

ts
// Listen for specifc query
bot.inlineQuery('my-query', ctx => { ... })
// Listen for any query
bot.on('inline_query', ctx => { ... })

Source

switchInlineCurrent ​

ts
switchInlineCurrent(text: MaybeDynamicString<C>, query: string);

Adds a new inline query button that acts on the current chat. The selected chat will be prefilled with the name of your bot. You may provide a text that is specified along with it. This will start an inline query.

Your bot will in turn receive updates for inline queries. You can listen to inline query updates like this:

ts
// Listen for specifc query
bot.inlineQuery('my-query', ctx => { ... })
// Listen for any query
bot.on('inline_query', ctx => { ... })

Source

switchInlineChosen ​

ts
switchInlineChosen(text: MaybeDynamicString<C>, query: SwitchInlineQueryChosenChat);

Adds a new inline query button. Telegram clients will let the user pick a chat when this button is pressed. This will start an inline query. The selected chat will be prefilled with the name of your bot. You may provide a text that is specified along with it.

Your bot will in turn receive updates for inline queries. You can listen to inline query updates like this:

ts
bot.on('inline_query', ctx => { ... })

Source

game ​

ts
game(text: MaybeDynamicString<C>);

Adds a new game query button, confer https://core.telegram.org/bots/api#games

This type of button must always be the first button in the first row.

Source

pay ​

ts
pay(text: MaybeDynamicString<C>);

Adds a new payment button, confer https://core.telegram.org/bots/api#payments

This type of button must always be the first button in the first row and can only be used in invoice messages.

Source

ts
// Overload 1
submenu(
  text: MaybeDynamicString<C>,
  menu: string,
  ...middleware: MenuMiddleware<C>[],
): this;
// Overload 2
submenu(
  text: TextAndPayload<C>,
  menu: string,
  ...middleware: MenuMiddleware<C & { match: string }>[],
): this;
// Overload 3
submenu(
  text: MaybePayloadString<C>,
  menu: string,
  ...middleware: MenuMiddleware<C>[],
): this;

Adds a button that navigates to a given submenu when pressed. You can pass in the identifier of another menu instance. This way, you can effectively create a network of menus with navigation between them.

It is necessary that you register the targeted submenu by calling menu.register(submenu). Otherwise, no navigation can be performed. Note that you then don’t need to call bot.use(submenu) anymore, all registered submenus will automatically become interactive, too.

You can also navigate to this submenu manually by calling ctx.menu.nav('sub-id'), where 'sub-id' is the identifier of the submenu.

You can call submenu.back() to add a button that navigates back to the parent menu, i.e. the menu at which you registered the submenu.

You can get back the submenu instance by calling parent.at('sub-id'), where 'sub-id' is the identifier you passed to the submenu.

Source

back ​

ts
// Overload 1
back(text: MaybeDynamicString<C>, ...middleware: MenuMiddleware<C>[]): this;
// Overload 2
back(text: TextAndPayload<C>, ...middleware: MenuMiddleware<C & { match: string }>[]): this;
// Overload 3
back(text: MaybePayloadString<C>, ...middleware: MenuMiddleware<C>[]): this;

Adds a text button that performs a navigation to the parent menu via ctx.menu.back().

Source

dynamic ​

ts
dynamic(rangeBuilder: (ctx: C, range: MenuRange<C>) => MaybePromise<MaybeRawRange<C> | void>);

This is a dynamic way to initialize menu. A typical use case is when you want to create an arbitrary menu, using the data from ctx.session:

ts
const menu = new Menu('root')
menu.dynamic(ctx => ctx.session.data.reduce((range, entry) => range.text(entry)), new Menu.Builder())
bot.command("start", async (ctx) => {
  await ctx.reply("Menu", {
     reply_markup: menu,
  });
});

Source

append ​

ts
append(range: MaybeRawRange<C>);

Appends a given range to this range. This will effectively replay all operations of the given range onto this range.
