A small, simple and customizable cookie consent bar for use in React applications.

Demo: https://mastermindzh.github.io/react-cookie-consent/

Example branch: https://github.com/Mastermindzh/react-cookie-consent/tree/example

Default look

Installation

npm install react-cookie-consent

or use yarn:

yarn add react-cookie-consent

Using it

You can import the cookie bar like this:

import CookieConsent from "react-cookie-consent";

If you want to set/remove cookies yourself you can optionally import Cookie (straight from js-cookie) like this:

import CookieConsent, { Cookies } from "react-cookie-consent";

Then you can use the component anywhere in your React app like so:

<CookieConsent>
    This website uses cookies to enhance the user experience.
</CookieConsent>

You can optionally set some props like this (next chapter will show all props):

<CookieConsent
    location="bottom"
    buttonText="Sure man!!"
    cookieName="myAwesomeCookieName2"
    style={{ background: "#2B373B" }}
    buttonStyle={{ color: "#4e503b", fontSize: "13px" }}
    expires={150}
>
    This website uses cookies to enhance the user experience.{" "}
    <span style={{ fontSize: "10px" }}>
    This bit of text is smaller :O
    </span>
</CookieConsent>

One of the props (onAccept) is a function, this function will be called after the user has clicked the accept button. You can provide a function like so:

<CookieConsent
    onAccept={() => {alert("yay!")}}
>

</CookieConsent>

Props

Prop	Type	Default value	Description
location	string, "top", "bottom" or "none"	"bottom"	Syntactic sugar to easily enable you to place the bar at the top or the bottom of the browser window. Use "none" to disable.
children	string or React component		Content to appear inside the bar
disableStyles	boolean	false	If enabled the component will have no default style. (you can still supply style through props)
hideOnAccept	boolean	true	If disabled the component will not hide it self after the accept button has been clicked. You will need to hide yourself (see onAccept)
acceptOnScroll	boolean	false	Defines whether "accept" should be fired after the user scrolls a certain distance (see acceptOnScrollPercentage)
acceptOnScrollPercentage	number	25	Percentage of the page height the user has to scroll to trigger the accept function if acceptOnScroll is enabled
buttonText	string or React component	"I understand"	Text to appear on the button
cookieName	string	"CookieConsent"	Name of the cookie used to track whether the user has agreed.
cookieValue	string or boolean or number	true	Value to be saved under the cookieName.
onAccept	function	() => {}	Function to be called after the accept button has been clicked.
debug	boolean	undefined	Bar will be drawn regardless of cookie for debugging purposes.
expires	number	365	Number of days before the cookie expires.
extraCookieOptions	object	{}	Extra info (apart from expiry date) to add to the cookie
containerClasses	string	""	CSS classes to apply to the surrounding container
buttonClasses	string	""	CSS classes to apply to the button
buttonId	string	""	Id to apply to the button
contentClasses	string	""	CSS classes to apply to the content
style	object	look at source	React styling object for the bar.
buttonStyle	object	look at source	React styling object for the button.
contentStyle	object	look at source	React styling object for the content.

Debugging it

Because the cookie consent bar will be hidden once accepted, you will have to set the prop debug={true} to evaluate styling changes:

<CookieConsent
    debug={true}
>
</CookieConsent>

Note: Dont forget to remove the debug-property for production.

Styling it

You can provide styling for the bar, the button and the content. Note that the bar has a display: flex property as default and is parent to its children "content" and "button".

The styling behaves kind of responsive. The minimum content width has been chosen to be "300px" as a default value. If the button does not fit into the same line it is wrapped around into the next line.

You can style each component by using the style, buttonStyle and contentStyle prop. These will append / replace the default styles of the components. Alternatively you can provide CSS classnames as containerClasses, buttonClasses and contentClasses to apply predefined CSS classes.

You can use disableStyles={true} to disable any built-in styling.

Examples

changing the bar background to red

<CookieConsent
    style={{ background: "red" }}
>
</CookieConsent>

changing the button font-weight to bold

<CookieConsent
    buttonStyle={{ fontWeight: "bold" }}
>
</CookieConsent>

Using predefined CSS classes

You can pass predefined CSS classes to the components using the containerClasses, buttonClasses and contentClasses props. The example below uses bootstrap classes:

    <CookieConsent
          disableStyles={true}
          location={OPTIONS.BOTTOM}
          buttonClasses="btn btn-primary"
          containerClasses="alert alert-warning col-lg-12"
          contentClasses="text-capitalize"
        >
          This website uses cookies to enhance the user experience.{" "}
          <span style={{ fontSize: "10px" }}>
            This bit of text is smaller :O
          </span>
        </CookieConsent>

Which results in:

Accept on scroll

You can make the cookiebar disappear after scrolling a certain percentage using acceptOnScroll and acceptOnScrollPercentage.

<CookieConsent
    acceptOnScroll={true}
    acceptOnScrollPercentage={50}
    onAccept={() => {alert("consent given")}}
>
    Hello scroller :)
</CookieConsent>

Extra cookie options

You can add more cookie options using the extraCookieOptions parameter like so:

<CookieConsent
    extraCookieOptions={{domain: 'myexample.com'}}
>
    cookie bar
</CookieConsent>

rainbows!

If you're crazy enough you can even make a rainbow colored bar:

<CookieConsent
    buttonText="OMG DOUBLE RAINBOW"
    cookieName="myAwesomeCookieName2"
    style={{ background: "linear-gradient(to right, orange , yellow, green, cyan, blue, violet)", textShadow: "2px 2px black" }}
    buttonStyle={{background: "linear-gradient(to left, orange , yellow, green, cyan, blue, violet)", color:"white", fontWeight: "bolder", textShadow: "2px 2px black"}}
>
    This website uses cookies to enhance the user experience.{" "}
    <span style={{ fontSize: "10px" }}>
    This bit of text is smaller :O
    </span>
</CookieConsent>
