useFetch()

useFetch hook is used to make fetch calls. It returns the data, error and loading states. It should be used ideally for 'GET', 'POST', 'PUT', 'PATCH' and 'DELETE' methods.

| Parameter | Required | Type | Default | Description |
| --------- | -------- | -------- | -------------------------------------------------- | ------------------------------------------------ |
| url | Yes | string | N.A | The url to be used for the fetch call |
| options | No | object | Default Options refer | The options object to be used for the fetch call |

$3

a. GET method

- If you want to use 'GET' method, then you do not have to provide the options object.
- If you are providing the options object, you do not have to explicitly provide the method property, as 'GET' is assumed by default.

`jsx
import { useFetch } from "@coderebus/react-hooks/fetch";

const { data, error, loading } = useFetch(url);

if (loading) {
return

Loading...

;
}

if (error) {
return

Error: {error}

;
}

return

{data}

;
`

b. POST (and other mutation methods)

If you want to use any method other than 'GET', then you have to provide the options object with the method and body properties.

`jsx
const options = {
method: 'POST' (required),
body: {
title: 'foo',
body: 'bar',
} (required)
other similar fetchOptions...
}

const { data, error, loading } = useFetch(url, options)
`

$3

These are the default properties (options) that are used if you do not provide any options object or its properties.

`jsx
const options = {
method: "GET", // 'POST', 'PUT', 'PATCH'...
headers: {
"Content-Type": "application/json",
},
credentials: "same-origin", // 'omit', 'include'
mode: "cors", // 'no-cors', 'same-origin'
cache: "default", // 'no-cache', 'reload', 'force-cache', 'only-if-cached'
redirect: "follow", // 'manual', 'error'
referrerPolicy: "no-referrer",
refetch: 3, // number of times to refetch in case of error
retryAfter: 1000, // time in milliseconds to wait before retrying
};
`

$3

a. using default values

`jsx

import { useResizeObserver } from "@coderebus/react-hooks/resize";

const MyComponent = () => {
const ref = useRef(null);
const size = useResizeObserver(ref);

return (

useDocumentTitle hook is used to update the document title.

| Parameter | Required | Type | Default | Description |
| --------- | -------- | -------- | ------- | --------------------------- |
| title | Yes | string | N.A | The title to set |

`

useMediaQuery()

useMediaQuery hook is used to manage and respond to media queries.

| Parameter | Required | Type | Default | Description |
| ------------------------ | -------- | -------- | ------- | --------------------------------------------------------------- |
| query | Yes | string | N.A | The media query string to match |
| defaultValue | No | boolean| false | The default value to use when initializing on the server |
| initializeWithValue | No | boolean| true | Determines whether the state should be initialized with the current match value of the media query when the component mounts |

- The hook returns a boolean indicating whether the media query matches.

> ### Server Side Rendering
>
> defaultValue: This is used to set a default value for the media query match when the code is running on the server. Since window is not available on the server, you'll want to provide a sensible defaultValue to prevent errors and ensure your components render correctly during initial page load.
>
> initializeWithValue: This option determines whether the hook should initialize the state with the current match value of the media query when the component mounts.If you want your UI to respond instantly to the media query on the initial render, set initializeWithValue to true (default). To avoid potential layout shifts or performance issues (or in SSR), set initializeWithValue to false.
>
> `jsx
> import { useMediaQuery } from "@coderebus/react-hooks/media";
>
> const MyComponent = () => {
> const isLargeScreen = useMediaQuery("(min-width: 1024px)", {
> defaultValue: true,
> initializeWithValue: false,
> });
>
> return

{isLargeScreen ? "Large Screen" : "Small Screen"}

;
> };
> `

$3

return

{isLargeScreen ? "Large Screen" : "Small Screen"}

;
};
`

useIsomorphicLayoutEffect

useIsomorphicLayoutEffect hook is a safe version of useLayoutEffect for SSR (Server-Side Rendering) environments. It uses useLayoutEffect on the client and useEffect on the server to avoid warnings about the use of useLayoutEffect in SSR.

$3

`jsx
import { useIsomorphicLayoutEffect } from "@coderebus/react-hooks/isomorphic";

const MyComponent = () => {
useIsomorphicLayoutEffect(() => {
console.log("Layout effect");
}, []);

return

Check the console

;

| Parameter | Required | Type | Default | Description |
| --------- | -------- | -------- | ------- | --------------------------------- |
| timeout | No | number | 2000 | The time (in milliseconds) before the copied state resets |

- The hook returns an object with the following properties:
- copy: A function to copy the specified text to the clipboard.
- reset: A function to reset the copied and error states.
- error: An Error object if the copy operation failed, or null if it succeeded.
- copied: A boolean indicating whether the copy operation was successful.

$3

`jsx
import { useClipboard } from "@coderebus/react-hooks/clipboard";

const MyComponent = () => {
const { copy, reset, error, copied } = useClipboard({ timeout: 3000 });

return (

copy("Hello, World!")}>Copy Text
{copied && Copied to clipboard!}
{error && Error: {error.message}}
Reset

};

export default MyComponent;
