This changeset removes webauthn from the Notify.gov admin app. We are not using webauthn at all in our implementation and will be looking at an entirely different authentication system in the near future.

For the "Something else" branding form we want the form label to be the
title. This brings in the textarea component from GOV.UK Frontend in
order to do this since that contains code to set a the textarea label as
the page heading in an accessible way.
The rest of the textarea fields have not been switched to use the new
component yet.
We added domdiff to replace the DiffDOM library
here:
87f54d1e88
DiffDOM had updated its code to be written to the
ECMAScript 6 (ES6) standard and so needed extra
work to work with the older browsers in our
support matrix. This was recorded as an issue
here:
https://www.pivotaltracker.com/n/projects/1443052/stories/165380360
Domdiff didn't work (see below for more details)
so this replaces it with the morphdom library.
Morphdom supports the same browsers as us and is
relied on by a range of large open source
projects:
https://github.com/patrick-steele-idem/morphdom#what-projects-are-using-morphdom
It was tricky to find alternatives to DiffDOM so
if we have to source alternatives in future, other
options could be:
- https://github.com/choojs/nanomorph
- https://diffhtml.org/index.html (using its
outerHTML method)
Why domdiff didn't work
Turns out that domdiff was replacing the page HTML
with the HTML from the AJAX response every time,
not just when they differed. This isn't a bug.
Domdiff is bare bones enough that it compares old
DOM nodes to new DOM nodes with ===. With our
code, this always results to false because our new
nodes are made from HTML strings from AJAX
response so are never the same node as the old
one.
A while ago diffDOM moved its code to use ES6
modules and started using various language
features specific to ES6. These two things
happened independently btw.
The result of this is that the version of diffDOM
suitable for our build pipeline, structured as an
immediately invoked function evocation (IIFE),
now requires polyfills of some ES6 features to
work in the older browsers we support, like IE11.
It's also worth noting that in the move to ES6
the maintainers of diffDOM have adopted a process
whereby users who need to support older browsers
now have to add polyfill code for any ES6 features
they choose to use.
This commmit proposes a move to the domdiff
library instead because:
- it runs on all javascript runtimes with no
polyfills
- it is 2KB instead of diffDOM's 25KB
Domdiff takes a different approach to diffDOM, in
that it compares existing nodes and new nodes and
replaces the existing ones with the new ones if
there are differences. By contrast, diffDOM will
make in-place changes to nodes if there are enough
similarities. In other words, in most situations,
diffDOM won't change the node in $component
whereas domdiff will.
Because of this, I've had to change the
updateContent.js code to cache the data-key
attribute's value so we don't lose access to it by
overwrite the $component variable with a different
jQuery selection.
this ensures it's reusable by other components, and easier to unit test
by isolating the separate concerns
note: this is not in Modules since that's designed for classes that are
then bound to an element in the DOM as indicated by a data-module
attribute. This will just live at the window.GOVUK level since we want
there to only ever be one `.banner-dangerous` warning.
