问题 I'm using Express and I'm trying to explicitly define res.locals . In the @types/express package, Express.Response.locals is any , so I can't seem to overwrite it: types/express/index.d.ts: declare namespace Express { interface Response { locals: { myVar: number } } } My Middleware: import * as express from 'express' function middleware( req: express.Request, res: express.Response, next: express.nextFunction ) { res.locals.myVar = '10' // I want this to throw a compiler error next() } I want

问题 I'm trying to understand what is difference between https and http/2? If i'm going to build node.js/express app, what should i use? Can i use https with http/2? Maybe if i use https, i don't need http/2 because it's the same or https use http/2 under the hood? I'm confused. Someone is linked to me "difference between HTTP 1.1 and HTTP 2.0 [closed]", but i understand differense between HTTP and HTTP2. I'm asking about HTTP S and HTTP/2 回答1: HTTP - A protocol used by clients (e.g. web browsers)

问题 Buffers in javascript seem to be capped at 2GB for 64bit systems. Using the express helper res.download found here my server crashes when trying to download a file that exceeds the same 2GB. I guess the solution would be to stream the file, from what I found it can be done using: var readStream = fileSystem.createReadStream('/tmp/outputs.zip'); readStream.pipe(res); Yet when I do this my axios client never receives a response to the GET request.

问题 I have a MERN stack app which uses Passport.js for Facebook/Twitter/Google authentication. In the development environment, everything works well and we are able to authenticate the user and log them into the application. After confirming the functionality in the development environment, we deployed to Heroku, but the same functionality is not working in production, and Passport.js is failing with a "TokenError" stating that the Domain URL is not included in the app's domains (even though we

问题 I am quite new to Node JS and express but I am trying to build a website which serves static files. After some research I've found out that NodeJS with Express can be quite useful for this. So far I managed to serve some static html files which are located on my server, but now I want to do something else: I have an URL to an html page, and in that html page, there is a table with some information. I want to extract specific a couple of values from it, and 1) save it as JSON in a file, 2)
