tryAsync

tryAsync<T>(fn: Promise<T>): Promise<Result<T, Error>>

Wraps a promise in a Result object, capturing success or error.

Overview

The tryAsync function is designed to handle asynchronous operations encapsulated within a Promise and return a Result object indicating either success or failure.

Parameters

• fn (Promise<T>): The promise to wrap.

Returns

• Promise<Result<T, Error>>: A promise that resolves to a Result object containing either the value from the resolved promise (T) or an Error object.

For more details on the Result primitive used in the tryAsync function, refer to the [Result primitive documentation].

Example Usage

import { tryAsync } from "koka-ts";
 
async function fetchData() {
  const result = await tryAsync(fetchDataFromServer());
 
  if (result.isErr()) {
    // handle error
    console.error(result.getErr());
  } else {
    // Process successful result
    console.log(result.unwrap());
  }
}
