# httpGet

Canonical: https://www.wiki.jodisand.me/snippets/javascript/httpget/


Makes a `GET` request to the passed URL.

- Use the `XMLHttpRequest` web API to make a `GET` request to the given `url`.
- Handle the `onload` event, by calling the given `callback` the `responseText`.
- Handle the `onerror` event, by running the provided `err` function.
- Omit the third argument, `err`, to log errors to the console's `error` stream by default.

```js
const httpGet = (url, callback, err = console.error) => {
  const request = new XMLHttpRequest();
  request.open('GET', url, true);
  request.onload = () => callback(request.responseText);
  request.onerror = () => err(request);
  request.send();
};
```

```js
httpGet(
  'https://jsonplaceholder.typicode.com/posts/1',
  console.log
); /*
