* Add data layer for discovery chain (model/adapter/serializer/repo)
* Add routing plus template for routing tab
* Add extra deps - consul-api-double upgrade plus ngraph for graphing
* Add discovery-chain and related components and helpers:
1. discovery-chain to orchestrate/view controller
2. route-card, splitter-card, resolver card to represent the 3 different
node types.
3. route-match helper for easy formatting of route rules
4. dom-position to figure out where things are in order to draw lines
5. svg-curve, simple wrapper around svg's <path d=""> attribute format.
6. data-structs service. This isn't super required but we are using
other data-structures provided by other third party npm modules in other
yet to be merged PRs. All of these types of things will live here for
easy access/injection/changability
7. Some additions to our css-var 'polyfill' for a couple of extra needed
rules
* Related CSS for discovery chain
1. We add a %card base component here, eventually this will go into our
base folder and %stats-card will also use it for a base component.
2. New icon for failovers
* ui: Discovery Chain Continued (#6939)
1. Add in the things we use for the animations
2 Use IntersectionObserver so we know when the tab is visible,
otherwise the dom-position helper won't work as the dom elements don't
have any display.
3. Add some base work for animations and use them a little
4. Try to detect if a resolver is a redirect. Right now this works for
datacenters and namespaces, but it can't work for services and subsets -
we are awaiting backend support for doing this properly.
5. Add a fake 'this service has no routes' route that says 'Default'
6. redirect icon
7. Add CSS.escape polyfill for Edge
1. Addition of external source icons for services marked as such.
2. New %with-tooltip css component (wip)
3. New 'no healthcheck' icon as external sources might not have
healthchecks, also minus icon on node cards in the service detail view
4. If a service doesn't have healthchecks, we use the [Services] tabs as the
default instead of the [Health Checks] tab in the Service detail page.
5. `css-var` helper. The idea here is that it will eventually be
replaced with pure css custom properties instead of having to use JS. It
would be nice to be able to build the css variables into the JS at build
time (you'd probably still want to specify in config which variables you
wanted available in JS), but that's possible future work.
Lastly there is probably a tiny bit more testing edits here than usual,
I noticed that there was an area where the dynamic mocking wasn't
happening, it was just using the mocks from consul-api-double, the mocks
I was 'dynamically' setting happened to be the same as the ones in
consul-api-double. I've fixed this here also but it wasn't effecting
anything until actually made certain values dynamic.
