React-Native-Logger

Sync or Async Aware logger for react-native

This Project address couple of issues

• Simple to use
• Group logs
• Filter Logs by name
• Async aware

Installation (NPM or Yarn)

npm install react-native-logger --save

yarn add react-native-logger

Usage

import { logger } from 'react-native-logger'

There are 3 functions.

log: (...args: Array) => void

similar to console.log. for example

logger.log('this is awesome', 10, 10)

// logs as
// this is awesome 10 10

group: (name: string, title: string, log: LogFn) => void

it accepts 3 arguments. name is an identifier which you can use in setFilters. title is a simple description about the log it self. and log is a function which your loggin happening. The signiture of LogFn is

type LogFn: (log: (...args: Array<any>) => void) => void | Promise<any>

It basically group related logs into one. also you can return a promise which cause the logs waits until you tell it so.

logger.group('api', 'loads users list', async (log) => {
  
  const users = await apis.getAllUsers();

  log('list of users', users);

  actions.updateUsersList(users);
});

setFilters: (...names: Array): void

simply filters out everything except those names that you pass to logs. to clear the filter simply call it without arguments.

logger.filters('api')
