Fast and easily write your logs into files and on console, it works with Ts as well with Js projects.

import Logger, { InitialConfig } from '@taikai/log-service'; /* * Create the configs for your initializing loggers (console and file) * */ const initConfig: InitialConfig = { appName: 'My App', hostname: 'localhost', version: '1.0', console: { silent: false, // log on console }, file: { silent: true, // doesn't log on file }, }; const blackListKeys = ['password', 'phoneNumber', 'address']; const logger = new Logger(blackListKeys, '*'); logger.init(initConfig); logger.i('Log something funny 🚀'); ...

:memo: Where do I start?

Step 1: Installation

This is a Node.js module available through the npm registry.

Before installing, download and install Node.js. prefer the LTS version.

If this is a brand new project, make sure to create a package.json first with the npm init command.

Installation is done using the npm install command:

$ npm i @taikai/log-service

Step 2: Log something with your logger

import the library into your file

use the import statement (in case of a typescript project):

import Logger, { InitialConfig } from '@taikai/log-service';

or require (if you are working in a js project):

const { default: Logger } = require('@taikai/log-service');

create a new instance of your Logger

prepare your config object and your blacklist elements (the elements which the info appearing after this should be masked):

... const initConfig: InitialConfig = { appName: 'My App', hostname: 'localhost', version: '1.0', console: { silent: false, }, file: { silent: true, }, }; const blackListKeys = ['password', 'phoneNumber', 'address']; const logger = new Logger(blackListKeys, '*'); logger.init(initConfig);

:bulb: Hint: If you are using a js project, you don't need to specify the types of variables :wink:.

start logging

After initiated yhe logger calling the method .init() you can start writing log messages into your files and/or your console depending on the values you set on the initConfig variable:

logger.i('Log something funny 🚀'); logger.d('I am being debugged 🚫🐞'); logger.w('You are about to love this lib ⚠'); logger.e('Oh no! Something went wrong 😱');

Now you can create a new branch containing the new feature or bugfix, e.g.: git checkout -b feature/my_new_feature. This will make it easier for you to submit a pull request and get your feature merged.

Test Options

Before submitting, you must pass all the unit tests and syntax checks by running the two commands below:

npm run test run all the unit test cases in tests folder

There're also a syntax check commands for you: npm run lint

There is a nested project called lib-tester where you can play and see how would work your new feature or bugfix. But first you need to run the build script on the root project, then install the dependencies on the nested project using the npm install command. It should install the local package NOT the published one:

... "@taikai/log-service": "file:../taikai-log-service-<VERSION>.tgz" ...
