建议在JavaScript无效之前包含CSS吗？

由 我们两清 提交于 2020-04-18 11:33:47
问题： In countless places online I have seen the recommendation to include CSS prior to JavaScript. 在网上无数的地方，我已经看到了在JavaScript之前包含CSS的建议。 The reasoning is generally, of this form : 一般来说，推理 的形式 如下： When it comes to ordering your CSS and JavaScript, you want your CSS to come first. 在订购CSS和JavaScript时，您希望首先使用CSS。 The reason is that the rendering thread has all the style information it needs to render the page. 原因是渲染线程具有渲染页面所需的所有样式信息。 If the JavaScript includes come first, the JavaScript engine has to parse it all before continuing on to the next set of resources. 如果首先包含JavaScript

EventMachine and Ruby Threads - what's really going on here?

由 随声附和 提交于 2020-03-18 12:47:10
问题 we use Rails and EventMachine together, and when using that combo with Passenger there is some very specific setup that needs to be done. After a lot of trial and error, I got EventMachine initialization working well, but I would like to understand the code a little better. As you can see below in this code snippet, our initializer checks for Passenger, and then checks if it's a forked process before restarting EventMachine. if defined?(PhusionPassenger) PhusionPassenger.on_event(:starting

How to decode a cookie from the header of a websocket connection handshake? (Ruby)

由 穿精又带淫゛_ 提交于 2020-01-10 04:14:27
问题 I am running a Sinatra app within an EventMachine.run loop and in my ws.onopen method I wish to check the handshake header's cookie to ensure that the incoming request is coming from a registered user of my webapp. My Sinatra app includes the following: use Rack::Session::Cookie, :key => COOKIE_KEY, :path => '/', :expire_after => 2592000, #30 days :secret => COOKIE_SECRET and my ws.onopen method looks like this (trimmed) ws.onopen { |handshake| cookie, bakesale = handshake.headers['Cookie']

问题 I have this simple javascript code : window.ws = new WebSocket('ws://127.0.0.1:8000/'); ws.onopen = function() { ws.send('hello'); } And a server in Ruby like this : require 'em-websocket' class Websocket def run EventMachine.run do EM::WebSocket.start(host: '0.0.0.0', port: '8000') do |ws| ws.onopen do |handshake| puts "Connected" end ws.onclose do puts "Closed" end ws.onmessage do |msg| p msg end end end end end When a connection is close, the server should print "Closed".

Rubyracer (V8 binding for Ruby) performs really slow

由 ☆樱花仙子☆ 提交于 2020-01-02 14:12:55
问题 So, I have a TCP server in eventmachine and therubyracer is used as a way to pre-pend operations (like filters or extensions) to the server. It all works charming when the server is not receiving a lot of data, but when it's being flooded (it is required sometimes) it becomes really slow. So, I did a small benchmark to see how slower the rubyracer is compared to Ruby, and I was shocked when I saw the results: user system total real V8: 0.060000 0.000000 0.060000 ( 0.059903) Ruby: 0.000000 0
