EventLog Microservice Client SDK for Node.js / ES2017

This is a Node.js client SDK for service-eventlog 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

* API Version 1

Install

Add dependency to the client SDK into package.json file of your project
``javascript
{
...
"dependencies": {
....
"client-eventlog-node": "^1.0.*",
...
}
}
`

Then install the dependency using npm tool
`bash


Install new dependencies

npm install

Update already installed dependencies

npm update
`

Use

Inside your code get the reference to the client SDK
`javascript
var sdk = new require('client-eventlog-node');
`

Define client configuration parameters that match configuration of the microservice external API
`javascript
// Client configuration
var config = {
connection: {
protocol: 'http',
host: 'localhost',
port: 8080
}
};
`

Instantiate the client and open connection to the microservice
`javascript
// Create the client instance
var client = sdk.EventLogHttpClientV1(config);

// Connect to the microservice
try {
await client.open(null);
// Work with the microservice
...
} catch(err) {
console.error('Connection to the microservice failed');
console.error(err);
}
`

Now the client is ready to perform operations
`javascript
// Log system event
let event = await client.logEvent(
null,
{
type: 'restart',
source: 'server 1',
message: 'Server restarted'
},
);
`

`javascript
var now = new Date();

// Get the list system events
let page = await client.getEvents(
null,
{
from: new Date(now.getTime() - 24 3600 1000),
to: now,
source: 'server 1'
},
{
total: true,
skip: 0,
take: 100
}
);
