console-class-browser

简体中文
This module implements the Node.js console module for browser environments.
The motivation came from my attempt to simulate a shell in the frontend, where I found that console-browserify did not implement the Console class.
I originally considered submitting a PR, but the changes required would likely be extensive and might be rejected. Therefore, I spent a few hours rewriting this module.

Usage

The usage of this module is mostly the same as the Node.js standard library, with some minor differences.
A simple example (test.js):

const console = require("console-class-browser")

console.group("SIMPLE LOG")
  console.group("LOG")
    console.log("Hello %s", "World")
    console.info("Hello %s", "World")
    console.debug("Hello %s", "World")
    console.dirxml("Hello %s", "World")
    console.table("Hello %s", "World") // TODO
    console.warn("Hello %s", "World")
    console.groupEnd()
  console.group("ERROR")
    console.error("Bye %s", "Bug")
    console.trace("Bye %s", "Bug")
    console.groupEnd()
  console.groupEnd()

console.groupCollapsed("UTIL LOG")
  console.assert(true, "Hello %s", "World")
  console.time("Time")
  console.timeLog("Time")
  console.timeEnd("Time")
  console.count("Count")
  console.count("Count")
  console.countReset("Count")
  console.log({key: "value"}, "Hello", "World")
  console.dir(console.Console.prototype, {depth: 0})
  console.groupEnd()

Example using the Console class:

// If you have your own stdout or stderr
var myConsole = new console.Console(stdout, stderr)
myConsole.log("Hello World")

TIP: It is recommended that stdout and stderr be Node.js writable stream objects. In practice, they can be any object containing a write method. If you want to use console.clear, the stdout should also implement a clear method.

BrowserStdout and BrowserStderr (simulating stderr and stdout in the browser):

console.stdout // Pre-instantiated stdout
console.stderr // Pre-instantiated stderr
// You can also instantiate your own
var stdout = new console.BrowserStdout()
var stderr = new console.BrowserStderr()

This module implements the following methods (excluding details that differ from the console module):

• label
• info
• warn
• table
• group
• groupEnd
• groupCollapsed
• dirxml
• trace
• profile
• profileEnd
• timeStamp
• debug
• log
• error
• assert
• clear
• dir
• count
• countReset
• time
• timeLog
• timeEnd
• createTask
• Console

Some methods are implemented as empty functions.

consoleClass-browser

本模块实现了Nodejs的console模块)
起因是我在尝试在前端模拟shell时候发现console-browserify没有实现Console类
本来想提一个pr的，但是要我改的话可能就要大变动了，八成可能会被拒绝，因此我就花几个小时重写了这个模块

Usage

本模块用法与Node标准库基本相同，细节有不同
一个简单的示例(test.js)

const console = require("console-class-browser")

console.group("SIMPLE LOG")
  console.group("LOG")
    console.log("Hello %s", "World")
    console.info("Hello %s", "World")
    console.debug("Hello %s", "World")
    console.dirxml("Hello %s", "World")
    console.table("Hello %s", "World") // TODO
    console.warn("Hello %s", "World")
    console.groupEnd()
  console.group("ERROR")
    console.error("Bye %s", "Bug")
    console.trace("Bye %s", "Bug")
    console.groupEnd()
  console.groupEnd()

console.groupCollapsed("UTIL LOG")
  console.assert(true, "Hello %s", "World")
  console.time("Time")
  console.timeLog("Time")
  console.timeEnd("Time")
  console.count("Count")
  console.count("Count")
  console.countReset("Count")
  console.log({key: "value"}, "Hello", "World")
  console.dir(console.Console.prototype, {depth: 0})
  console.groupEnd()

Console类示例

// 如果你有自己的stdout或stderr
var myConsole = new console.Console(stdout, stderr)
myConsole.log("Hello World")

TIP: 建议stdout和stderr是一个nodejs的可写流对象，实际上可以是任何包含write方法的对象，如果希望console.clear还需要在stdout上实现clear方法

BrowserStdout和BrowserStderr(在浏览器上模拟stderr和stdout)

console.stdout // 已经实例化的stdout
console.stderr // 已经实例化的stderr
// 也可以自己实例化一个
var stdout = new console.BrowserStdout()
var stderr = new console.BrowserStderr()

本模块实现了以下方法(不包括与console模块不同的细节)

• label
• info
• warn
• table
• group
• groupEnd
• groupCollapsed
• dirxml
• trace
• profile
• profileEnd
• timeStamp
• debug
• log
• error
• assert
• clear
• dir
• count
• countReset
• time
• timeLog
• timeEnd
• createTask
• Console

部分方法使用空函数实现
