express

问题 I've inherited a node.js/Express app that is a bit of a mess. It's regularly and fairly randomly getting stuck and not responding to any request until it is restarted. I suspect that something within the app is blocking and either getting stuck in a loop or making a request to an external api without using proper Async techniques, and never getting a response and never timing out at witch point the server just stops responding but doesn't crash. I would obviously like to find the culprit code

问题 in one file (otherFile.js) I have this: exports = function() {} in my main file I have this: var thing = require('./otherFile.js'); new thing(); however this gives me the following error: TypeError: object is not a function and if in otherFile.js I have this instead: exports.myFunction = function() {} and in my main file I have this: var thing = require('./otherFile.js'); new thing.myFunction(); then it works perfectly. Why is it that I'm not allowed to assign a function to the exports

问题 I am working on an express node app that posts to twitter when a user inputs an image into a form. I am saving the image locally before uploading, which works.

问题 How I can use React-Router to point directly to a route defined with Express on the backend instead of rendering a component? I want to return valid JSON with no HTML included in the response. 回答1: React-Router only handles routing on the React frontend. There is no way for React-Router to point to an Express Route on the back end. A React component would have to use that API endpoint. Why not just hit the endpoint manually. 来源： https://stackoverflow.com/questions/61162675/can-react-router
