Logging Microservice Client SDK for Node.js

This is a Node.js client SDK for pip-services-logging microservice. It provides an easy to use abstraction over communication protocols:

  • HTTP/REST client
  • Seneca client (see http://www.senecajs.org)
  • Direct client for monolythic deployments
  • Null client to be used in testing

This client SDK also contains Direct, REST and Seneca loggers that allow to directly log into the microservice.

Quick Links:

Install

Add dependency to the client SDK into package.json file of your project

{
    ...
    "dependencies": {
        ....
        "pip-clients-logging-node": "^1.0.*",
        ...
    }
}

Then install the dependency using npm tool

# Install new dependencies 
npm install
 
# Update already installed dependencies 
npm update

Use

Inside your code get the reference to the client SDK

var sdk = new require('pip-clients-logging-node');

Define client configuration parameters that match configuration of the microservice external API

// Client configuration
var config = {
    connection: {
        protocol: 'http',
        host: 'localhost', 
        port: 8080
    }
};

Instantiate the client and open connection to the microservice

// Create the client instance
var client = sdk.LoggingHttpClientV1(config);
 
// Connect to the microservice
client.open(null, function(err) {
    if (err) {
        console.error('Connection to the microservice failed');
        console.error(err);
        return;
    }
    
    // Work with the microservice
    ...
});

Now the client is ready to perform operations

// Log message
client.writeMessage(
    null,
    { 
        type: 'restart',
        source: 'server 1',
        message: 'Server restarted'
    },
    function (err, event) {
        ...
    }
);
var now = new Date();
 
// Get the messages for server 1 for the last day
client.readMessages(
    null,
    {
        from: new Date(now.getTime() - 24 * 3600 * 1000),
        to: now,
        source: 'server 1'
    },
    {
        total: true,
        skip: 0, 
        take: 100
    },
    function(err, page) {
    ...    
    }
);
