Functional Approach

This package provides alternatives to many functions that are not throwing any errors, but returning them. We recommend using such package as fp-ts to process such kind of results.

Here are some examples:

import * as E from 'fp-ts/Either';
import { pipe } from 'fp-ts/function';
import { postEventFp, retrieveLaunchParamsFp } from '@tma.js/bridge';

pipe(postEventFp('web_app_expand'), E.match(
  error => {
    // error will be typed here, you will know exactly what is wrong.
  },
  () => {
    // Everything is ok.
  },
));

pipe(retrieveLaunchParamsFp(), E.match(
  error => {
    // ...
  },
  launchParams => {
    // ...
  },
));
