> A react hook for using the [Streams API](https://developer.mozilla.org/en-US/docs/Web/API/Streams_API) with the [Fetch API](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API) to stream data from a server.

15+
16+
### Installation
17+
----------------
18+
You can install this package from [NPM](https://www.npmjs.com):
19+
```bash
20+
npm add react-fetch-streams
21+
```
22+
23+
Or with [Yarn](https://yarnpkg.com/en):
24+
```bash
25+
yarn add react-fetch-streams
26+
```
27+
28+
#### CDN
29+
For CDN, you can use [unpkg](https://unpkg.com):
30+
31+
[https://unpkg.com/react-fetch-streams/dist/index.min.js](https://unpkg.com/react-fetch-streams/dist/index.min.js)
32+
33+
The global namespace for react-fetch-streams is `reactFetchStreams`:
34+
```html
35+
<script type="text/javascript" src="https://unpkg.com/react-fetch-streams/dist/index.min.js"></script>
36+
37+
<script type="text/javascript">
38+
const {useStream} = reactFetchStreams;
39+
...
40+
</script>
41+
42+
```
43+
44+
### Usage
45+
---------
46+
Stream some data from some server:
47+
```jsx
48+
import React, {useCallback, useState} from 'react';
49+
import {useStream} from 'react-fetch-streams';
50+
51+
const MyComponent = props => {
52+
const [data, setData] = useState({});
53+
const onNext = useCallback(async res => {
54+
const data = await res.json();
55+
setData(data);
56+
}, [setData]);
57+
useStream('http://myserver.io/stream', {onNext});
58+
59+
return (
60+
<React.Fragment>
61+
{data.myProp}
62+
</React.Fragment>
63+
);
64+
};
65+
```
66+
67+
You can also pass the fetch request init props using `fetchParams`:
68+
```jsx
69+
import React, {useCallback, useState} from 'react';
70+
import {useStream} from 'react-fetch-streams';
71+
72+
const fetchParams = {mode: 'cors'}
73+
74+
const MyComponent = props => {
75+
const [data, setData] = useState({});
76+
const onNext = useCallback(async res => {
77+
const data = await res.json();
78+
setData(data);
79+
}, [setData]);
80+
useStream('http://myserver.io/stream', {onNext, fetchParams});
81+
82+
return (
83+
<React.Fragment>
84+
{data.myProp}
85+
</React.Fragment>
86+
);
87+
};
88+
```
89+
90+
For more examples, please check the [tests](./src/stream.test.js).
