Previously `api-double` usage in ember would require a bunch of `fetch` requests to pull in the 'api double', this had a number of disadvantages. 1. The doubles needed to be available via HTTP, which meant a short term solution of rsyncing the double files over to `public` in order to be served over HTTP. An alternative to that would have been figuring out how to serve something straight from `node_modules`, which would have been preferable. 2. ember/testem would not serve dot files (so anything starting with a ., like `.config`. To solve this via ember/testem would have involved digging in to understand how to enable the serving of dot files. 3. ember/testem automatically rewrote urls for non-existant files to folders, i.e. adding a slash for you, so `/v1/connect/intentions` would be rewritten to `/v1/connect/intentions/`. This is undesirable, and solving this via ember/testem would have involved digging deep to disable that. Serving the files via HTTP has now changed. The double files are now embedded into the HTML has 'embedded templates' that can be found by using the url of the file and a simple `querySelector`. This of course only happens during testing and means I can fully control the 'serving' of the doubles now, so I can say goodbye to the need to move files around, worry about the need to serve dotfiles and the undesirable trailing slashes rewriting. Winner! Find the files and embedding them is done using a straightforward recursive-readdir-sync (the `content-for` functionality is a synchronous api) as oppose to getting stuck into `broccoli`.
Consul 
- Website: https://www.consul.io

Consul is a tool for service discovery and configuration. Consul is distributed, highly available, and extremely scalable.
Consul provides several key features:
-
Service Discovery - Consul makes it simple for services to register themselves and to discover other services via a DNS or HTTP interface. External services such as SaaS providers can be registered as well.
-
Health Checking - Health Checking enables Consul to quickly alert operators about any issues in a cluster. The integration with service discovery prevents routing traffic to unhealthy hosts and enables service level circuit breakers.
-
Key/Value Storage - A flexible key/value store enables storing dynamic configuration, feature flagging, coordination, leader election and more. The simple HTTP API makes it easy to use anywhere.
-
Multi-Datacenter - Consul is built to be datacenter aware, and can support any number of regions without complex configuration.
-
Service Segmentation - Consul Connect enables secure service-to-service communication with automatic TLS encryption and identity-based authorization.
Consul runs on Linux, Mac OS X, FreeBSD, Solaris, and Windows. A commercial version called Consul Enterprise is also available.

Developing Consul
If you wish to work on Consul itself, you'll first need Go installed (version 1.9+ is required). Make sure you have Go properly installed, including setting up your GOPATH.
Next, clone this repository into $GOPATH/src/github.com/hashicorp/consul and
then just type make. In a few moments, you'll have a working consul executable:
$ make
...
$ bin/consul
...
Note: make will build all os/architecture combinations. Set the environment variable CONSUL_DEV=1 to build it just for your local machine's os/architecture, or use make dev.
Note: make will also place a copy of the binary in the first part of your $GOPATH.
You can run tests by typing make test. The test suite may fail if
over-parallelized, so if you are seeing stochastic failures try
GOTEST_FLAGS="-p 2 -parallel 2" make test.
If you make any changes to the code, run make format in order to automatically
format the code according to Go standards.
Vendoring
Consul currently uses govendor for
vendoring and vendorfmt for formatting
vendor.json to a more merge-friendly "one line per package" format.
