[![IT Man - Tech #32 - Async await wrapper for easy error handling without try-catch [Vietnamese]](https://i.ytimg.com/vi/iLB75jzQrJ8/hqdefault.jpg)](https://www.youtube.com/watch?v=iLB75jzQrJ8)
## Prerequisites
- [Bun — fast all-in-one JavaScript runtime](https://bun.sh/)
## Libraries
- [scopsy/await-to-js: Async await wrapper for easy error handling without try-catch](https://github.com/scopsy/await-to-js)
## Install
```sh
bun install
```
## Usage
This is simple usage for await-to-js with Bun.
```typescript
// index.ts
import { to } from "await-to-js";
interface ServerResponse {
test: number;
}
const p = Promise.resolve({ test: 123 });
const pError = Promise.reject(new Error("Test error"));
const [err, data] = await to(p);
if (err) console.error(err);
console.log(data?.test);
// Output: 123
const [err2] = await to(pError);
if (err2) console.error(err2);
// Output: Error: Test error
```
```sh
❯ bun run index.ts
123
3 | interface ServerResponse {
4 | test: number;
5 | }
6 |
7 | const p = Promise.resolve({ test: 123 });
8 | const pError = Promise.reject(new Error("Test error"));
