There are many places in the API where we receive a property set to `null` which can then lead to defensive code deeper in the app in order to guard for this type of thing when usually we are expecting an array or for the property to be undefined using omitempty on the backend. Previously we had two places where we would deal with this in the serializer using our 'remove-null' util (KV and Intentions). This new decorator lets you declaritively define this type of data using a decorator @NullValue([]) (which would replce a null value with []. @NullValue in turn uses a more generic @replace helper, which we currently don't need but would let you replace any value with another, not just a null value. An additional benefit here is that the guard/replacement is executed lazily when we get the property instead of serializing all the values when they come in via the API. On super large datasets, where we only visualize part of the dataset (say in our scroll panes), this feels like a good improvement on the previous approach. |

Consul 
- Website: https://www.consul.io
- Tutorials: HashiCorp Learn
- Forum: Discuss
Consul is a distributed, highly available, and data center aware solution to connect and configure applications across dynamic, distributed infrastructure.
Consul provides several key features:
-
Multi-Datacenter - Consul is built to be datacenter aware, and can support any number of regions without complex configuration.
-
Service Mesh/Service Segmentation - Consul Connect enables secure service-to-service communication with automatic TLS encryption and identity-based authorization. Applications can use sidecar proxies in a service mesh configuration to establish TLS connections for inbound and outbound connections without being aware of Connect at all.
-
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.
Consul runs on Linux, Mac OS X, FreeBSD, Solaris, and Windows. A commercial version called Consul Enterprise is also available.
Please note: We take Consul's security and our users' trust very seriously. If you believe you have found a security issue in Consul, please responsibly disclose by contacting us at security@hashicorp.com.
