问题 currently I use app.use(express.static('public')) and my files located in the public folder of my node js express app and its working good. However, I would like to store those files (index.html, etc) in my s3 bucket (so multiple apps can use this website). I tried app.get('/', function(req, res) { res.sendfile('link-to-s3-file/index.html'); }); with no success... 回答1: I wouldn't reinvent the wheel.

问题 I'm looking for a simple example of a Node/Express/Jade page being updated using an Ajax call with both the client and server side code. I'm having a bit of trouble putting it all together in my head. 回答1: There are great many ways this could be done and it's not immediately apparent which approach you want to take. I suppose the simplest scenario would be to add some client-side logic to fetch pieces of html from the server and update the client. This is easily achieved using jQuery (put it

问题 I use expressJS as my NodeJS server. The user sends me his login info through a POST and after checking the credentials I render a page: router.post("/login", function (req: Request, res: Response, next) { if(credentialsOK){ res.render('main'); } }); The problem is that the URL becomes http://myaddress/login and I would like to remove the /login of the address. I don't want to use redirect as I want to send local variables through the render. How can I change the URL? 回答1: You can still pass

问题 I'm diving into NodeJS and Express (it's sooo complicated to me) to build a real-time web app. At the moment, I'm trying to understand how I can use an existing javascript library on the server side. The problem is the library appears to be designed to run on the client side and, as a result, the instructions only show you how to use it on the client side. The library I'm talking about can be found here... https://github.com/replit/jsrepl Questions: Since a NodeJS web app is built on

问题 I'm trying to build a chat application based on sails.js. The url for messages from a specific chat looks like this: /api/chat/:id/messages When I request this url with XHR, it provides a session cookie and sails.js builds a session object. I can easily check user rights to read the messages from the specific chat. However, I need to request this url with socket.io so that the client can subscribe to all future changes of the messages collection. When I request this url with socket.io, no

问题 I am trying to deploy a Heroku app, and I believe the procfile may be the reason my app is not deploying. I've tried multiple solutions including: web: node ./bin/www web: npm start There may be another reason my app is not working, but I want to make sure my Procfile is set up correctly 回答1: This is what I have: A file in the root directory of the project called Procfile (no file extension) Inside the file, the first line reads web: bin/web In the bin directory which is also located in the
