telegram-webapp-solid v0.8.1

Telegram Webapp for SolidJs

A SolidJs wrapper for creating Telegram Webapp.

Usage

Import this package in your app (Javascript or Typescript)

npm i --save telegram-webapp-solid
yarn add telegram-webapp-solid
pnpm add telegram-webapp-solid

Then you can use ready-made components or signals.

Components are truly declarative ways of using the API, signals are a more procedural approach and should be use to get more control over the API.

Components

Components are a declarative way to use Telegram Webapp capabilities.

AlertButton

This is a regular button that spawns an alert when clicked.

See : Alert

Alert

When this component is rendered, shows an alert to the user.
An alert is just a message with a "close" button.

BackButton

When this component is rendered, the app's exit button turns into a back button, where you can provide a onClick callback

Also available as a signal with createBackButtonSignal

ConfirmButton

This is a regular button that spawns a confirm popup when clicked.

See : Confirm

Confirm

When this component is rendered, shows a confirm popup to the user.
A confirm popup is a message with a "OK" and a "cancel" button. When the user chooses "OK", the popup returns true, when the user chooses "cancel" or click away it returns false

HapticButton

This is a standard <button/> except it vibrates when touched on mobile (you can pass a hapticForce prop to change the intensity)

HapticInput

This is a standard <input/> except it vibrates when focused on mobile (it uses a specific haptic force for selections)

MainButton

When this component is rendered, the app's main button appears on the bottom of the screen. You can provide a text prop, an active boolean prop, a progressVisible boolean prop, a hapticForce setting and a onClick callback

Also available as a signal with createMainButtonSignal

PopupButton

This is a regular button that spawns a popup when clicked.

See : Popup

Popup

When this component is rendered, shows a popup to the user.
A popup is a message with 1-3 buttons. When the user chooses a button, the popup returns the id of the pressed button.

Buttons can be one of :

• default, a button with the default style,
• ok, a button with the localized text “OK”,
• close, a button with the localized text “Close”,
• cancel, a button with the localized text “Cancel”,
• destructive, a button with a style that indicates a destructive action (e.g. “Remove”, “Delete”, etc.).

QRCodeButton

When this component is rendered, brings up a QR code scanner on the screen.
You can provide a callback to get back the scanned text.

StableContainer

A standard <main/> except it uses css variables provided by telegram to render only inside the space of the web app.

Signals

Signals are not always true reactive signals, but they provide a procedural approach to the Telegram Webapp API.

createBackButtonSignal

Returns an object to see and change the visibility of the back button

createDataSignal

Returns a [initData, sendData] tuple that are only wrapped around the API

createExpandSignal

Returns a [expanded, expand] tuple where expanded is a boolean indicating if the app is expanded and expand is a function that expands the app

createHapticImpactSignal

Takes a hapticForce prop and returns a function that vibrates the device with the given intensity

createHapticSelectionSignal

Returns a function that vibrates the device with a specific intensity made for selections

createLifecycleSignal

Returns a { ready, close } object that are only wrapped around the API

createMainButtonSignal

Returns an object to see and change the visibility of the main button.

createOpenSignal

Returns an object to open link, Telegram links and invoices (simple wrappers around the API). You can also use onInvoiceClosed as a shorthand to the invoiceClosed event

createPromptQrCodeScanSignal

Returns a function that opens the QR Code scanner and returns a promise with the scanned text

createThemeSignal

Returns an object with a theme key, which is a reactive theme object and also setHeaderColor() and setBackgroundColor().
