We use a `<DataSource @src={{url}} />` component throughout our UI for when we want to load data from within our components. The URL specified as the `@src` is used to map/lookup what is used in to retrieve data, for example we mostly use our repository methods wrapped with our Promise backed `EventSource` implementation, but DataSource URLs can also be mapped to EventTarget backed `EventSource`s and native `EventSource`s or `WebSockets` if we ever need to use those (for example these are options for potential streaming support with the Consul backend).
The URL to function/method mapping previous to this PR used a very naive humongous `switch` statement which was a temporary 'this is fine for the moment' solution, although we'd always wanted to replace with something more manageable.
Here we add `wayfarer` as a dependency - a very small (1kb), very fast, radix trie based router, and use that to perform the URL to function/method mapping.
This essentially turns every `DataSource` into a very small SPA - change its URL and the view of data changes. When the data itself changes, either the yielded view of data changes or the `onchange` event is fired with the changed data, making the externally sourced view of data completely reactive.
```javascript
// use the new decorator a service somewhere to annotate/decorate
// a method with the URL that can be used to access this method
@dataSource('/:ns/:dc/services')
async findAllByDatacenter(params) {
// get the data
}
// can use with JS in a route somewhere
async model() {
return this.data.source(uri => uri`/${nspace}/${dc}/services`)
}
```
```hbs
{{!-- or just straight in a template using the component --}}
<DataSource @src="/default/dc1/services" @onchange="" />
```
This also uses a new `container` Service to automatically execute/import certain services yet not execute them. This new service also provides a lookup that supports both standard ember DI lookup plus Class based lookup or these specific services. Lastly we also provide another debug function called DataSourceRoutes() which can be called from console which gives you a list of URLs and their mappings.
* ui: Convert Service.GatewayConfig to a model fragment
We added the ember-intl addon, which has its own format-number helper.
We replaced our own similarly named helper with this one, but the
ember-intl one is far stricter and errors if the arguments passed are
undefined. Our previously one would cope with this.
We'd rather continue to use the stricter ember-intl helper, so here we
convert the GatewayConfig property to a model fragment so that we can
give the GatewayConfig.AssociatedServices property a default zero value.
* ui: Add the most basic workspace root in /ui
* We already have a LICENSE file in the repository root
* Change directory path in build scripts ui-v2 -> ui
* Make yarn install flags configurable from elsewhere
* Minimal workspace root makefile
* Call the new docker specific target
* Update yarn in the docker build image
* Reconfigure the netlify target and move to the higher makefile
* Move ui-v2 -> ui/packages/consul-ui
* Change repo root to refleect new folder structure
* Temporarily don't hoist consul-api-double
* Fixup CI configuration
* Fixup lint errors
* Fixup Netlify target
