hooli-logger-client v1.0.2

Hooli logger server

Behind the need to see and control the logs of applications and microservices based on express and NodeJS that run in containers through serverless infrastructure from any provider, and with easy integration without complications and for free.

The leganux team developed a set of tools that would solve these problems in a very simple way. The Hooli logger project allows users of node/express projects to implement a fast, efficient and visual service that allows them to manage their logs.

This service allows you to view, analyze, filter and obtain the context of:

• console.log
• console.info
• console.warn
• console.error
• console.debug *http requests

In real time and in a visual and managed way

How to use

Configure ExpressJS basic project server

First clone the server repository

$ git clone "https://github.com/leganux/hooli-logger-server.git"

Install the dependences

$ npm i

Modify Configuration Config.js

module.exports = {
  log_rotate_cron: '0 * * * *', //indicates every time runs cron of log rotate
  log_rotate_hours: 12,//indicates delete data from 12 hour back
  listen_port: 3333,//Port wich run server
  db_flavor: 'sqlite', /* sqlite, mariadb, mysql*/
  db_host: 'localhost', //host server DB  of not sqlite
  db_port: '00000',//port DB  of not sqlite
  db_username: '',//username DB  of not sqlite
  db_password: '',//password DB  of not sqlite
  db_filename: 'my_db.sqlite', // only for sqlite
  db_name: 'hooli', //  for all databases
  user: 'hooli', // Coming soon login
  password: 'CFm7AWR3tezcuyBg', // Coming soon login
}

Run server

$ node app.js

Visit website

https://myhostdomain.com:3333/web

Configure Client in your node project

Install package

npm i hooli-logger-client

Import package

let hooli = require("hooli-logger-client")

New instance declaration

let logger = new hooli('https://myhostdomain.com:3333', 'The name of your APP', 'The source. EG. ID container or Environment')

Replacing default log functions from NodeJS console

const _privateLog = console.log;
const _privateError = console.error;
const _privateInfo = console.info;
const _privateWarn = console.warn;
const _privateDebug = console.debug;

console.log = async function (message) {
  _privateLog.apply(console, arguments);
  logger.log(arguments)

};
console.error = async function (message) {
  _privateError.apply(console, arguments);
  logger.error(arguments)
};
console.info = async function (message) {
  _privateInfo.apply(console, arguments);
  logger.info(arguments)
};
console.warn = async function (message) {
  _privateWarn.apply(console, arguments);
  logger.warn(arguments)
};
console.debug = async function (message) {

  _privateDebug.apply(console, arguments);
  logger.debug(arguments)

};

For requests install Morgan Middleware in express

npm i morgan

let morgan = require('morgan')

app.use(morgan(function (tokens, req, res) {

  let cadenamorgan = [
    moment().format('YYYY-MM-DD hh:mm:ss'),
    tokens.method(req, res),
    tokens.url(req, res),
    tokens.status(req, res),
    tokens['response-time'](req, res), 'ms'
  ].join('  ');

  /*  Implement request logger  */
  logger.request(JSON.stringify({
    method: tokens.method(req, res),
    url: tokens.url(req, res),
    status: tokens.status(req, res),
    body: req.body,
    query: req.query,
    params: req.params,
  }))

  return cadenamorgan;
}));

And that's all folks
