User Story: As a dev/customer I would like to know how the rlo_08 + rlp_02 do work together in a real application

• Demo web client app sends the HTTP request message (message1) to the node server

• Server uses the RLO_08 library to build the Syslog message including the User Agent details from the Demo web client app and send HTTP response for the demo web client app request

  • log the user agent used in the request

• Display the syslog message with rlp_03 example application (https://github.com/teragrep/java-relp-server-demo)

• Use github workflow to setup the environment:

  • Launch the rlp_03 for listening data

    • Show logged lines of the rlp_03

  • Launch server with rlo_08 and rlp_02

    • RELP Connection should be kept online for sending meaning not connect and disconnect for each message.

  • Launch demo web client app

    • Make request

High-level Architecture

Implementation

• Package.json installation of rlp_02 and rlo_08

  npm install

• Module usage:

  const { SyslogMessage, Facility, SDElement, SDParam, Severity } = require('@teragrep/rlo_08')
  const { RelpConnection, RelpBatch } = require('@teragrep/rlp_02')

• RelpConnection usage:

  async function setupConnection(port, host){
      return new Promise(async (resolve, reject) => {
        relpConnection = new RelpConnection();
        let conn = await relpConnection.connect(port, host);
        console.log('Connectig...',host,' at PORT ', port)
        resolve(relpConnection)
      })
    }

• Runtime INSTRUCTIONS

  • First, Make sure that run our java-relp-server-demo application jar

    java -jar java-relp-server-demo-jar-with-dependencies.jar

  • Build

    mvn clean package

• OPTIONAL TIPS

  • You can run the test-server and make curl request to the server listening port at 3000

  • * Run Server:

    node test-server.js

  • CURL request to the our test server running on PORT 3000

    curl localhost:3000/ua
