Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Installation

$ npm install taf-utils

01. 配置文件解析器

var Config = require('taf-utils').Config;

API

parseFile(sFilePath, [encoding, callback])

解析指定文件

  • sFilePath: 文件名
  • encoding: 文件编码类型。 (默认值: utf8)
  • callback: 回调函数,回调函数的格式 function callback(ret, config){}, 其中ret为对象{code: 返回码,成功为0, 失败为-1, message: 描述, exception:如果成功为undefined,如果失败为事件对象}, config为解析器本身

parseText(sText)

解析字符串,并将解析的结果存于内部的_data属性中,可以通过get方法获取相应的值

  • sText: 字符串
  • return: true:解析成功, false: 解析失败

get(key, defaultValue)

文件被解析之后,会将结果存储到一个对象中,通过get方法可以获取制定的值。注:如果配置文件/字符串中有相同的key,则get获取key对应的值时,不会获取所有的值,而是获取该key最后对应的那个值,也可以理解为对应相同的key后面的值覆盖前面的值。

  • key: 需要取值的key值,格式为x1.x2.x3,其中x1,x2,x3依次为深层次的key,注:如果key值本身为x1.x2格式,取该key对应的值时需要写成< x1.x2>,具体使用参见例子。
  • defaultValue: 取不到结果的默认值

getDomain(key, defaultValue)

获取key对应的值中类型为Object的属性数组

  • key: key值。
  • defaultValue: 取不到结果的默认值

getDomainValue(key, defaultValue)

获取key对应的值中类型为Object的属性值数组

  • key: key值。
  • defaultValue: 取不到结果的默认值

getDomainLine(key, defaultValue)

获取key对应路径下的所有非空行

  • key: key值。
  • defaultValue: 取不到结果的默认值
  • return: 数组

data

通过该属性,可以获取文件解析的结果

example

var Config = require('taf-utils').Config;

var config = new Config();
config.parseFile('./config.conf', 'utf8');

var data = config.data;
console.log('data: ', data);
console.log('get: taf.application.server.<TRom.ThemeStoreServer.ThemeStore1ObjAdapter>: ', config.get("taf.application.server.<TRom.ThemeStoreServer.ThemeStore1ObjAdapter>"));
console.log('get: taf.application.server.local: ', config.get('taf.application.server.local'));
console.log('getDomain: taf.application.server: ', config.getDomain('taf.application.server'));
console.log('getDomainValue: taf.application.server: ', config.getDomainValue('taf.application.server'));

具体例子参见examples目录下的test-config.js文件

02. Endpoint工具

var Endpoint = require('taf-utils').Endpoint;

API

Class方法:parse(desc)

从字符串中解析出Endpoint信息

  • desc: 字符串,例如:'tcp -h 10.136.167.31 -p 19386 -t 60000'
  • return: 返回Endpoint实例。

toString()

Endpoint信息转化成字符串

copy()

拷贝Endpoint实例

example

var Endpoint = require('taf-utils').Endpoint;

var endpoint = Endpoint.parse('tcp -h 10.136.167.31 -p 19386 -t 60000');
console.log('endpoint: ' + endpoint.toString());
console.log('endpoint.copy: ' + endpoint.copy().toString());

具体例子参见examples目录下的test-endpoint.js文件

03. timeProvider工具

var timeProvider = require('taf-utils').timeProvider;

API

nowTimestamp()

采用Date.now()的方式获取时间,此种方式效率最高,Date.now()的方式的效率大概是new Date().getTime()的2倍,是process.hrtime() 方式的4倍。

  • return: 返回对象
{
    hrtime: // 数组类型,[秒, 纳秒],
    timestamp: // 单位ms
}

diff(oTime)

当前时间相对于oTime的时间间隔

  • oTime: 相对时间,nowTimestamp函数返回的对象类型
  • return: 浮点类型,时间间隔,单位毫秒
  • 注:nowTimestamp和diff配对使用

dateTimestamp()

获取当前的时间戳, 即机器从启动到当前的时间(process.hrtime)

  • return: 返回对象
{
    hrtime: // 数组类型,[秒, 纳秒],
    timestamp: // 单位ms
}

dateTimestampDiff(oTime)

当前时间相对于oTime的时间间隔

  • oTime: 相对时间,dateTimestamp函数返回的对象类型
  • return: 浮点类型,时间间隔,单位毫秒
  • 注:dateTimestamp和dateTimestampDiff配对使用

example

var timeProvider = require('../index').timeProvider;

var i = 0, count = 10000000;
var tt1, tt2, interval = 0;
var t1 = new Date().getTime();
var t2 = t1;

tt1 = timeProvider.nowTimestamp();
for(i = 0; i < count; i++)
{
    tt2 = timeProvider.diff(tt1);
}
t2 = new Date().getTime();
console.log('【hrTime】interval: ' + (t2 - t1));

t1 = new Date().getTime();
tt1 = timeProvider.dateTimestamp();
for(i = 0; i < count; i++)
{
    tt2 = timeProvider.dateTimestampDiff(tt1);
}
t2 = new Date().getTime();
console.log('【hrTime】interval: ' + (t2 - t1));
