node.js

问题 I have a capture.js file included as a script in index.html which capture image on click via webcam. I need to send the base64URL of the captured image in zeromq client server (TCP client) written in node js so that I can connect send it later to a python zeromq server(TCP server). I have tried a lot of way and searched a lot for the weeks, there is no CDN link for zeromq and couldn't be able to compile it and also the variable shows undefined in client.js . I will really appreciate if any

问题 I'd like to use the MongoClient.Connect(Url) option for connecting from Node and in fact it does work for authenticated connections to the admin database. However, if I try to specify a different database I get an "auth Fails" with code 18. I think this means that the credentials are only setup on the admin database and, unfortunately, I can't change this arrangement (for now, anyway). It seems this Url syntax is the direction the driver is heading, so I'd like to use it if possible. Is there

问题 I am making a next js application. Deployment works fine in vercel. For deploying the same project in another server, got help from https://stackoverflow.com/a/63660079/13270726 and used the same instructions in our app. Deployed the out directory into server using ftp client.

(Even page refresh also works fine in this page) -> If we move to about page using the url, http://your-domain.com/about then it also works but on page

问题 The second part of the Promise below (inside the then ) is never run. When I run the database query without using the Promise(in a node script that I run node myscript.js it returns the data but the console never returns the prompt--the console just hangs and I have to send an interrupt manually. Therefore, when I put it inside a Promise, I think the Promise doesn't know that the database query is complete even though it seems to have returned all the data, therefore the second part of the

问题 I'm looking to create an app with optional modules that I will not know the names of in the application. For example, imagine outlook, but the calendar/tasklist/mail pieces are optional components, you would npm install outlook-framework then create your app that requires "outlook-framework" but then I would like to import all packages installed that start with "outlook-". So I can npm install outlook-mail and that gives me email support, same for outlook-calendar , or even something I didn't

问题 Right now, I'm trying to make an API, and one of its functions is to take a file and upload it to another website, sort of like uploading a file through the API as some sort of "proxy". The website I'm sending the file to requires additional steps to work (namely sending the destination in another request) and I wanted to have my API do that all in one request instead, where that request already had all the details needed. I've gotten the request for the destination done, but I'm having a
