Add `isSupported` to `all.mjs` #5250

Closed patrickpatrickpatrick closed 1 month ago

patrickpatrickpatrick commented 1 month ago

What

Why

isSupported is a method that will be very useful for developers creating their own components that dependent on the govuk-frontend. isSupported returns a boolean to indicate if the browser is supported by govuk-frontend by checking for presence of the govuk-frontend-supported on the body of the page.

Fixes https://github.com/alphagov/govuk-frontend/issues/5210
