有没有办法在Visual Studio Code中使用组件或HTML完成？因为当我们有像Bootstrap等类这样的类时,手动输入每个字母并不是一个好主意.例如,在Emmet中完成:ul>li*2>a

var React = require('react');

var Header = React.createClass({
    render: function () {
        return (

            <nav className="navbar navbar-defaullt">
                <div className="container-fluid">
                    <a href="/" className="navbar-brand">
                        <img width="50" height="50" src="images/logo.png" alt="logo" />
                    </a>
                    <ul className="nav navbar-nav">
                        <li><a href="/">Home</a></li>
                        <li><a href="/#about">About</a></li>
                    </ul>
                </div>
            </nav>

                );
                }
                });
module.exports  = Header;

有没有办法在使用自定义域的GitHub页面网站上使用HTTPS/SSL？建议使用SSL以获得更好的搜索引擎排名,除此之外还有很多其他用途.

我正在尝试使用快速服务器创建反应应用程序.设置服务器后我点击请求我得到了

GET http://localhost:3333/%PUBLIC_URL%/favicon.ico 400 (Bad Request)

在错误预览它给我

URIError: Failed to decode param '/%PUBLIC_URL%/favicon.ico'

这是服务器代码

var express = require('express');
var bodyParser = require('body-parser');
var path = require ('path');

var data = {};

express()
    .use(express.static(path.resolve(__dirname, '..', 'public')))
    .use(bodyParser.json())

    .get('/api/data', (req, res) => res.json(data))

    .post('/api/data', (req, res) => res.json(data = req.body))

    .get('*', …

curl -I -H 'Accept-Encoding: gzip,deflate' https://example.com/a.min.js

在这里，很明显该文件已压缩，但是在chrome，pagespeed和gtmetrix的情况下，他们提到该文件未压缩。当我在Chrome浏览器中查看时，标头中没有内容编码。

我的主页也被gzipp压缩了。使用varvy服务时，他们说您的本地文件未压缩。

我在nginx和apache中都启用了压缩。也在.htaccess中。但这很奇怪。

在安装sinopia之前一切正常,但在那之后npm失败了.PLZ帮我回滚到原始设置.
每当它尝试安装新的npm包时都会出错.例如.当我跑这个
