问题 I'm working on moving a React app to SSR using NextJS and per the docs, I'm using the CSS and LESS modules for Next. The problem is that it seems that only one works at a time. Some of the app still relies on Bootstrap for now, and I have not been able to get the Bootstrap (either CSS or LESS) to work with these loaders. The main problem is that files like .ttf, .svg, .gif, etc are referenced inside the Bootstrap stylesheets but the loaders aren't in the Next modules. Here's a general idea of

问题 I have a chat application on Node.js and Socket.io, user can connect and disconnect with a button... I am having a list of online users which is perfectly managed with the help of my defined events that user trigger. But the problem is I am unable to detect if the user has lost his connection or closed the browser window without disconnecting himself manually(by the disconnect button)... This socket.io event is fired only when user disconnects himself not when he lost his connection. socket

问题 I need to call ssjs from a java bean similar to this this issue. The issue is that the code I need to execute comes from a configuration document, and may look like: getComponent("xxx").getValue(); I have built a version that does : String compute = doc.getItemValueString("SSJSStuff"); String valueExpr = "#{javascript:" + compute + "}"; FacesContext fc = FacesContext.getCurrentInstance(); Application app = fc.getApplication(); ValueBinding vb = app.createValueBinding(valueExpr); String vreslt

问题 In an isomorphic application with Reactjs, you need to pass the identical initial state that was rendered on the server down to the client (which will then 'rehydrate' the app with event bindings and such). I've seen two approaches to passing this initial state down-- Setting a global variable to the window: <script> window.initialState = {{JSON.stringify(initialState)}} ; </script> Or passing it as a JSON object: <script id="initial-state" type="application/json"> {{JSON.stringify

问题 Is there any way to run a Javascript engine, like Spidermonkey, on Google App Engine? Spidermonkey is a C module, so obviously that wont work (GAE doesn't allow those types of modules)... is there something else available? 回答1: Google is now supporting custom language on Google App Engine. So we can do Node.js https://www.youtube.com/watch?v=Q8jZHc0NS6A https://developers.google.com/cloud/managed-vms 回答2: Here is an article about running Rhino on AppEngine/Java. That should get you a long way

问题 I am trying to get my head round node.js... I am very happy with my LAMP set up as it currently fulfils my requirements. Although I want to add some real-time features into my PHP app. Such as showing all users currently logged into my site and possible chat features. I don't want to replace my PHP backend, but I do want scalable real-time solutions. 1. Can I throw node.js into the mix to serve my needs without rebuilding the whole application server-side script? 2. How best could node.js
