@scaleway/cookie-consent

This package is an helper to handle cookie consents with Segment integrations. It will handle the cookie consent for each categories.

This package does not contain design element to display a cookie consent modal, it only handle the storage and the init of cookie consent in a React provider.

QuickStart

In order to use it, first you need to provide a context at the top level of your application

import { PropsWithChildren } from 'react'

const MyApp = ({ children }: PropsWithChildren) => {
  return (
    <CookieConsentProvider
      isConsentRequired // Switch off consents if not defined (usefull for E2E testing)
      essentialIntegrations={[]} // List of mandatory integrations
      config={{
        segment, // Segment configuration used to get dynamically the integration used
      }}
      // not required
      cookiePrefix="_scw_rgpd" // default value
      consentMaxAge={13 * 30 * 24 * 60 * 60} // default value (appx 13 months)
      consentAdvertisingMaxAge={6 * 30 * 24 * 60 * 60} // default value (appx 6 months)
      cookiesOptions={{ sameSite: 'strict', secure: true, path: '/' }} // default value
    >
      {children}
    </CookieConsentProvider>
  )
}

Then in your cookie modal component you could simply use exposed hook to get and modify consents

export function PanelConsent() {
  const { saveConsent, categoriesConsent } = useCookieConsent()

  const setAllConsents = ({
    categoriesConsent,
    value,
  }: {
    categoriesConsent: Partial<Consent>
    value: boolean
  }) =>
    Object.keys(categoriesConsent).reduce(
      (acc, category) => ({ ...acc, [category]: value }),
      {},
    )

  const handleClick = (consentForAll: boolean) => () => {
    saveConsent(setAllConsents({ categoriesConsent, value: consentForAll }))
  }

  const onAgreeAll = handleClick(true)

  const onReject = handleClick(false)

  return (
    <div className={styles.consent}>
      <div>Do you accept consents ?</div>
      <div>
        <Button onClick={onAgreeAll} autoFocus>
          Accept
        </Button>
        <Button onClick={onReject}>Decline</Button>
      </div>
    </div>
  )
}

Segment Consent Middleware

As it's necessary now to have a consent management. https://segment.com/docs/privacy/consent-management/configure-consent-management/

you will have the possibility to add the SegmentConsentMiddleware, be aware that there is a dependency with SegmenttProvider.
