Synopsis

Mouette.js is a lightweight logger written in Typescript.

Motivation

The purpose of this library is to provide a simple and easy way to log infos throughout your code.

Installation

NPM

$ npm install @lcluber/mouettejs

Yarn

$ yarn add @lcluber/mouettejs

Usage

ES6

import { Logger, Group } from "@lcluber/mouettejs";

// some variables to log
var string = 'test';
var number = 2345;
var array  = [1,2,3,4];
var object = {
  string: 'test',
  number: 2345,
  array: [1,2,3,4],
  object: {yo: 'yo', ye: 'ye'}
};

var newLogsGroup = Logger.addGroup("newLogsGroup");

newLogsGroup.setLevel("info");
newLogsGroup.displayConsole(true);

newLogsGroup.info(string);
newLogsGroup.trace(number);
newLogsGroup.warn(array);
newLogsGroup.error(object);

newLogsGroup.time("timing log");
for (i = 0; i < 100000; i++) {
  // some code
}
newLogsGroup.time("timing log");

var logs = Logger.getLogs();

console.log('logs', logs);

var sendLogs = Logger.sendLogs('http://httpbin.org/post');
sendLogs.then((responseData) => {
  console.log(responseData); //status response 
});

API Reference

type LevelName = "info" | "time" | "trace" | "warn" | "error" | "off";
type LogContent = string | number | any[] | Object;

static Logger.setLevel(name: LevelName): LevelName {} // set the minimum level at which logs can be stored and displayed into console. Note that this setting will propagate to every group. You can set a different level for a group AFTER setting the level for the entire logger.
static Logger.getLevel(): LevelName {} // get the general level of the logger. Note that groups can have a different level if changed afterwards at group level
static Logger.displayConsole(value: boolean): boolean {} // set wether or not to display logs into console at logger level. Note that this setting will propagate to every group. This option can be changed individually for each group if changed afterwards at group level
static Logger.addGroup(name: string): Group {} // create a new group of logs
static Logger.getLogs(): Log[] {} // get all the logs in 1 array
static Logger.sendLogs(url: string, headers: Headers): Promise<response> {} // sends all the logs to given backend API ans reset logs if success.
static Logger.resetLogs(): void {} // Delete every logs of every group 

Group.setLevel(name: LevelName): levelName {} // set the minimum level at which logs of this group can be stored and displayed into console
Group.getLevel(): LevelName {} // get the level at which logs of this group can be displayed
Group.displayConsole(value: boolean): boolean {} // set wether or not to display logs into console
Group.setMaxLength(length: number): number {} // set the maximum quantity of logs stored by this group
Group.getMaxLength(): number {} // get the maximum quantity of logs stored by this group

Group.info(log: LogContent): void {} // create an info log
Group.time(key: string | number): void {} // create a time log. Use the same method to start or stop the timer. Using the same key, first call will start it, second call will stop it and return the elapsed time between the two.
Group.trace(log: LogContent): void {} // create a trace log
Group.warn(log: LogContent): void {} // create a warn log
Group.error(log: LogContent): void {} // create an error log

  info:   { id:  1, name: "info",  color: "#28a745" },
