`ThemeParams`

The component which contains an information about currently used theme by the Telegram application.

Initialization

Component constructor accepts an object with where each key describes the palette key and value specifies its color.

typescript

import { ThemeParams } from '@tma.js/sdk';

const themeParams = new ThemeParams({
  backgroundColor: '#ffaabb',
  buttonColor: '#113222',
  buttonTextColor: '#aabc33',
  hintColor: '#00ff00',
  linkColor: '#a32213',
  secondaryBackgroundColor: '#000000',
  textColor: '#aaaaaa',
});

import { ThemeParams } from '@tma.js/sdk';

const themeParams = new ThemeParams({
  backgroundColor: '#ffaabb',
  buttonColor: '#113222',
  buttonTextColor: '#aabc33',
  hintColor: '#00ff00',
  linkColor: '#a32213',
  secondaryBackgroundColor: '#000000',
  textColor: '#aaaaaa',
});

Requesting actual data

To get the actual theme parameters information, developer could use the requestThemeParams function:

typescript

import { requestThemeParams } from '@tma.js/sdk';

requestThemeParams.then(console.log);

// Output:
// { backgroundColor: '#ffaabb', ... }

import { requestThemeParams } from '@tma.js/sdk';

requestThemeParams.then(console.log);

// Output:
// { backgroundColor: '#ffaabb', ... }

Colors

The developer can retrieve the theme color by using the get method:

typescript

themeParams.get('backgroundColor');
themeParams.get('packageUnknownColor');

themeParams.get('backgroundColor');
themeParams.get('packageUnknownColor');

To retrieve all colors via one object, use getState method:

typescript

themeParams.getState();
// Output:
// {
//   accentTextColor: '#aa1399',
//   backgroundColor: '#baac12',
//   linkColor: '#887722'
//   packageUnknownColor: '#676767,
// }

themeParams.getState();
// Output:
// {
//   accentTextColor: '#aa1399',
//   backgroundColor: '#baac12',
//   linkColor: '#887722'
//   packageUnknownColor: '#676767,
// }
