[dependabot-preview]

Bumps moleculer from 0.11.5 to 0.12.4.

Release notes

Sourced from moleculer's releases.

v0.12.4

New

Graceful shutdown

Thanks for [rmccallum81](https://github.com/rmccallum81), ServiceBroker supports graceful shutdown. You can enable it with trackContext broker option. If you enable it, all services wait for all running contexts before shutdowning. You can also define a timeout value with gracefulStopTimeout broker option.

const broker = new ServiceBroker({
    trackContext: true,
    gracefulStopTimeout: 5 * 1000 // waiting max 5 sec
});

This timeout can be overwrite in service settings with $gracefulStopTimeout property.

Changes

• fix service registry update after reconnecting. #262
• update index.d.ts
• update dependencies
• fix distributed timeout handling

v0.12.3

Changes

• fix empty service mixins issue (mixins: []).
• update index.d.ts

v0.12.2

New

Latency strategy

This strategy selects a node which has the lowest latency, measured by periodic PING. Notice that the strategy only ping one of nodes from a single host. Due to the node list can be very long, it gets samples and selects the host with the lowest latency from only samples instead of the whole node list.

Usage

let broker = new ServiceBroker({
    registry: {
        strategy: "Latency"
    }
});

Strategy options

Name	Type	Default	Description
sampleCount	Number	5	the number of samples. If you have a lot of hosts/nodes, it's recommended to increase the value.
lowLatency	Number	10	the low latency (ms). The node which has lower latency than this value is selected immediately.
collectCount	Number	5	the number of measured latency per host to keep in order to calculate the average latency.
pingInterval	Number	10	ping interval (s). If you have a lot of host/nodes, it's recommended to increase the value.
