How Node js app register to Spring eureka?

问题

Is it possible to implement node js app as a spring eureka client? I use eureka-js-client to register spring eureka server, it always response 404 error.

回答1:

Check out the README of eureka-js-client for some helpful tips on this error.

If you are using Spring Cloud you'll likely want to set servicePath under the eureka section of your client configuration to /eureka/apps/.

回答2:

Yes It is possible, Check these three files in repo.

eureka: {
    host: 'localhost',
    port: 8761,
    servicePath: '/eureka/apps/'
  }

To this part in server.js you have to a add your own details (port and host details, If you have hosted in seperate machine you should add that machine's IP address as host)

Eureka server can be configured for non-jvm applications such as the nodeJS using the sidecar concept. Essentially, this concept differs from the previous answer in it requires a small spring application (the sidecar) to directly discover Eureka server, handle registration and health checks. Additionally, the nodeJS application must have a designated endpoint known to the sidecar application for periodic health check status updates. A possible message provided from this health check uri could be:

{
   "status":"UP"
}

You can take a look at this git repo for a sample implementation. For detail description of the sidecar concept, take a look at this documentation. The diagram below (taken from this GitHub repo above) provides a graphical explanation.
