node.js

问题 I reinstalled multiple times NPM and Node on my pc. (npm version 7.4.3) (node version v15.7.0) I followed the procedure for configuring the Firebase CLI with: npm install -g firebase-tools and firebase init and firebase deploy and the configuration seems to work fine. The problem I'm facing happens when I open the index.js file and I uncomment the stock helloWorld function which looks like this: exports.helloWorld = functions.https.onRequest((request, response) => { functions.logger.info(

问题 As a learning exercise, I am attempting to build a router in Node.js, which is meant to be reusable. The file structure for my router looks like this: /myProject app.js /routes index.js about.js /modules /router router.js In app.js , I create a router object, and pass it the path to my routes folder: var Router = require('./modules/router/router'); var router = new Router('./routes'); Within the constructor of the router object, I load filenames into an array from the path passed to the

问题 I've come across a problem on one of my Nodejs apps running with npm start (which just does node app.js ). My app contains a sigint handler as follows: process.on('SIGINT', () => { db.disconnect().then({ process.exit(0); }).catch(e => process.exit(1)); }); With corresponding logs. After some testing on other files, I've noticed that Ctrl-C when on an npm process triggers SIGINT twice if the first one takes too long to exit. (try adding a timeout on a sample app). For now I've added a counter

问题 req.protocol is not picking up "https" for my secure link. It always pics "http" . For creating my baseURL am using this. any solutions please? 回答1: That's happening most probably because there is a proxy in between. In my case I am using Heroku. If that's the case, you need to add app.enable('trust proxy'); to your express app. Without enabling that, req.protocol returned http . After that change I got https . You can also use req.secure to get true or false depending on if your app is

问题 I am working on an online multiplayer cards against humanity game (React on the front, React router for redirecting, and Node in the back) I am trying to redirect all clients in a "lobby", or room, when one user in the lobby clicks "start", but right now only the user that clicks start is redirected.

问题 Suppose I have a document for example: var doc = Model.findOne({name:"name"}); Now if the document gets edited trough another connection the the database, doc doesn't hold the right information. I do need it, so I have to "refresh" or "redownload" it from the database. Is there any way to do this with only the object "doc"? 回答1: Assuming doc contains the document instance to refresh, you can do this to generically refresh it: doc.model(doc.constructor.modelName).findOne({_id: doc._id},

问题 I use Sequelize for my Server (with mysql dialect); in Sequelize's documentation is written that this: var Task = this.sequelize.define('Task', { title: Sequelize.STRING }) , User = this.sequelize.define('User', { username: Sequelize.STRING }) User.hasMany(Task) Task.belongsTo(User) creates automatically foreign key references with constraints; but for me this doesn't happen: var Shop = sequelize.define('Shop', { name: Sequelize.STRING, address: Sequelize.STRING, phone: Sequelize.STRING,
