Intro

Description of Service Node Module RPC Pub-sub

---

• RPC Client/Server - Used for request / response from service to service
• Pub-sub - Used to publish & subscribe messages from module to module
• Discover - Automatic service discovery, and broadcast the node's entry, exit, update and other messages
• Balancer - Client side load balancing which built on service discovery. Provide smooth weighted round-robin balancing by default
• Elector - Select a unique master node for the same name service
• Tracer - Distributed tracing system, used to monitor the internal state of the program running in microservices
• Linkcache - Link cache used to maintain connection information in distributed systems

Quick start

s := braid.NewService("gate")   // create a new node in the service gate

// register module in node
s.Register(
    braid.Module(braid.LoggerZap),
    braid.Module(braid.PubsubNsq,
        pubsubnsq.WithLookupAddr([]string{mock.NSQLookupdAddr}),
        pubsubnsq.WithNsqdAddr([]string{mock.NsqdAddr}, []string{mock.NsqdHttpAddr}),
    ),
    braid.Module(
        braid.DiscoverConsul,    // discover module
        discoverconsul.WithConsulAddr(consulAddr)
    ),
)

s.Init()
s.Run()

defer s.Close()
