Add context.json configuration metadata

{
    "name": "bearcat-remote",
    "dependencies": {
        "bearcat-remote": "*"
    }
}

Exposing services using dnode

• Exporting the service using the dnodeServiceExporter Of cource, we first have to set up our service in Bearcat IoC container:

remoteService.js

var remoteService = function() {

}

remoteService.prototype.remotePing = function(ping, cb) {
    console.log(ping);
    cb('pong');
}

module.exports = remoteService;

{
    "id": "remoteService",
    "func": "remoteService"
}

Next we’ll have to expose our service using the dnodeServiceExporter:

{
    "id": "dnodeServiceExporter",
    "func": "node_modules.bearcat-remote.lib.remote.dnode.dnodeServiceExporter",
    "props": [{
        "name": "service",
        "ref": "remoteService"
    }, {
        "name": "port",
        "value": 8003 
    }, {
        "name": "host",
        "value": "localhost" 
    }]
}

• Linking in the service at the client Exposing our service using the dnodeDynamicProxy:

{
    "id": "dnodeClient",
    "func": "node_modules.bearcat-remote.lib.remote.dnode.dnodeDynamicProxy",
    "init": "dyInit",
    "async": true,
    "destroy": "dyDestroy",
    "props": [{
        "name": "serviceHost",
        "value": "localhost"
    }, {
        "name": "servicePort",
        "value": 8003
    }, {
        "name": "serviceInterface",
        "value": ["remotePing"]
    }]
}

Startup Bearcat and run it

var Bearcat = require('bearcat');

var simplepath = require.resolve('./context.json');
var paths = [simplepath];
var bearcat = Bearcat.createApp(paths);

bearcat.start(function() {
    var dnodeClient = bearcat.getBean('dnodeClient');
    dnodeClient.remotePing('ping', function(msg) {
        console.log(msg); // pong
    });
});
