fetch
The Fetch API provides an interface for fetching resources (including across the network). It will seem familiar to anyone who has usedXMLHttpRequest
, but the new API provides a more powerful and flexible feature set.
Not supported on all browsers. You can polyfill using
watchwg-fetch
yarn add node-fetch
Importing:
fetch-import-success.ts
import fetch from 'node-fetch';
If you use webpack, the following will work locally, but fail when deployed in webpack.
fetch-webpack-import-fail.ts
import * as fetch from 'node-fetch';
fetch-text.ts
const response = await fetch(url);
console.log(response);
const text = await response.text();
response
:fetch-text-response.ts
{
ok true,
status: 200,
...
}
fetch-json.ts
const response = await fetch(url);
const json = await response.json();
- No errors are thrown.
- No need for try/catch
fetch-error.ts
const response = await fetch(url);
console.log(response);
if (!response.ok) {
...
}
response
:fetch-error-response.json
{
ok false,
status: 404,
}
