express-server-logs

This is an express middleware for displaying logs in the console and also logging your custom error, info, warning and success messages in console with colors for the messages.

Usage

Works like any other middleware in express

const express = require('express');
const bodyParser = require('body-parser');
const _expressLog = require('express-server-logs');

const app = express();
const log = new _expressLog();

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(log.logger);

Using with options express-server-logs takes 2 arguments one for productionMode and other is options

const log = new _expressLog(productionMode, options);

productionMode can be true or false, for true your custom messages will not display to console and for false it will.

Options here is an object

{
  date: true,
  url: true,
  method: true,
  headers: true,
  pathParam: true,
  bodyParam: true,
  queryParam: true
}

Set value of key to false if you don't want that info to be display in logs. By default productionMode is false and options have true for all keys

Example

const log = new _expressLog(true, {
                                    date: true,
                                    url: true,
                                    method: true,
                                    headers: true,
                                    pathParam: false,
                                    bodyParam: true,
                                    queryParam: true
                                  });

Using custom messages from express-server-logs

You can log your custom error messages to console using predefined messages in express-server-logs Pre defined custom messages are of type info(), success(), error(), warning()

Example

log.info('test info'); // for info color will be blue
log.success('test success'); // for success color is green
log.error('test error'); // for error color is red
log.warning('test warning'); // for warning color is yellow

Note

• express-server-logs should be use after the body parser *
• for productionMode = true the custom messages will not be displayed to console *
