Reading from file (require)

由 半腔热情 提交于 2019-12-02 09:43:36
I have something like this: http://i.imgur.com/KPulyBg.png and im currently working on "admin" folder and inside of that i have "admin.php", but the problem is that i want to read "core/init.php" from there. Now i have this in admin.php <?php require '../includes/header.php'; ?> <?php $user = new User(); if(!$user->isLoggedIn()){ Redirect::to(404); } else if(!$user->hasPermission('admin')){ Redirect::to(404); } ?> <div id="content"> </div> <?php require '../includes/footer.php'; ?> And inside the "includes/header.php" i have php require_once 'core/init.php'; but i get this for my admin page:

Webpack require expression external

由 二次信任 提交于 2019-12-02 08:00:42
问题 I have an expression require which should get resolved in runtime but I can’t get my head around the webpack config for this simple example: import something from 'module'; import pkg from './package.json'; let a; if (pkg.main) { a = require(pkg.main); } The resulting build should contain the module but also require ./package.json and pkg.main in runtime as commonjs modules — in other words, exclude them from the build. My webpack.config.js so far: var webpack = require('webpack'); module

node.js的iconv模块----在linux上读取windows编码文件

由 大憨熊 提交于 2019-12-02 07:07:51
有时候我们在windows上会保存一些中文文字信息文件，然而由于编码集的差异，这文件在linux上显示为乱码，其中一种解决方法是node.js的iconv模块 var fs = require('fs'); var readstream = fs.createReadStream('./新建文本文档.txt'); var str=''; var iconv = require('iconv-lite'); var count=0; readstream.on('data',function (chunk) { str+=iconv.decode(chunk,'GBK'); count++; }); readstream.on('end',function () { console.log(str.toString()); console.log("文件分"+count+"次读完") }); 来源： https://www.cnblogs.com/saintdingspage/p/11735862.html

15import和require区别

由 房东的猫 提交于 2019-12-02 05:57:30
JS 中的require 和 import 区别 在研究react和webpack的时候，经常看到在js文件中出现require，还有import，这两个都是为了JS模块化编程使用。CSS的是@import 1.ES6 模块的设计思想，是尽量的静态化，使得编译时就能确定模块的依赖关系，以及输入和输出的变量。 Require是CommonJS的语法，CommonJS的模块是对象，输入时必须查找对象属性。 // CommonJS模块 let { stat, exists, readFile } = require('fs'); // 等同于 let _fs = require('fs'); let stat = _fs.stat; let exists = _fs.exists; let readfile = _fs.readfile; above：整体加载fs模块（即加载fs所有方法），生成一个对象"_fs"，然后再从这个对象上读取三个方法，这叫“运行时加载”，因为只有运行时才能得到这个对象，不能在编译时做到静态化。 ES6模块不是对象，而是通过export命令显示指定输出代码，再通过import输入。 import { stat, exists, readFile } from 'fs'; above：从fs加载“stat, exists, readFile” 三个方法

Equivalent of requiring a subproperty in ES6 import

由 我的梦境 提交于 2019-12-02 04:32:16
问题 I have an existing require : const {dialog} = require('electron').remote; I started using Babel for ES6, and would like to import this instead. So far I have: import electron from 'electron'; const {dialog} = electron.remote; This is ugly, and I can't help but feel there is a better way to do this. I just need the dialog here. How do I get at it in one line? 回答1: ECMAScript module syntax doesn't allow deep destructuring. In fact it doesn't destructure at all. Import statements create live

On-demand require()

由 守給你的承諾、 提交于 2019-12-02 02:18:32
Say I create a library in ./libname which contains one main file: main.js and multiple optional library files which are occasionally used with the main object: a.js and b.js . I create index.js file with the following: exports.MainClass = require('main.js').MainClass; // shortcut exports.a = require('a'); exports.b = require('b'); And now I can use the library as follows: var lib = require('./libname'); lib.MainClass; lib.a.Something; // Here I need the optional utility object lib.b.SomeOtherThing; However, that means, I load 'a.js' and 'b.js' always and not when I really need them. Sure I can

文章来自： 公众号平台–代码技巧 阅读文章前先唠叨一下：群发文章第三篇为小编分享的视频教程（视频+密码或者视频+朋友圈），有需要的可以查看。 Composer是一个非常流行的PHP包依赖管理工具,已经取代PEAR包管理器,对于PHP开发者来说掌握Composer是必须的. 对于使用者来说Composer非常的简单,通过简单的一条命令将需要的代码包下载到 vendor 目录下,然后开发者就可以引入包并使用了. 其中的关键在于你项目定义的 composer.json ,可以定义项目需要依赖的包(可能有多个),而依赖的包可能又依赖其他的包(这就是组件的好处),这些都不用你烦心,Composer会自动下载你需要的一切,一切在于 composer.json 的定义. Composer对于使用者来说是很透明,但是其背后的理念还是需要了解一下的,其的诞生也不是偶然的,得益于Github的快速发展,PHP语言也越来越现代化,显得更高大上了. 为了理解Composer,先大概了解下其结构: Composer的结构 Composer命令行工具 : 这个理解就比较简单了,通过使用者定义的 Composer.json 去下载你需要的代码,假如只是简单的使用Composer,那么掌握一些具体命令就完全可以了 Autoloading代码加载器 : 通过Composer,开发者可以通过多种方式去使用
