问题 I need to set up a Polka (or Express) server so that it can serve multiple applications (one per hostname) from a single server.js entry point. It can be done using the vhost middleware (https://github.com/expressjs/vhost). Each app is exported as a middleware, and the one that corresponds to each request is added in the middleware chain in server.js . However, some (not all) of these apps will be Sapper applications so the setup must be compatible with Sapper. So far as I am aware, Sapper

问题 I am writing a web application using Express framework to generate Impress.js presentations and apply a visual editor on them. I have set up the app.js for only getting the .html file but I want to inject a javascript code from a separate file before the body closing tag of the .html file.

问题 I am newer to Node.js/Express and am attempting a simple file upload to Azure blob storage. I am using AngularJS for the front end form. When I attempt to upload a file I receive the following error: TypeError: Cannot read property 'myfile' of undefined I have seen some examples where they are leveraging a node module named multiparty but am unsure if it applies to this basic upload need.

问题 I'm writing program that uses React as front-end, and an Express/Node API for the backend which then does CRUD operations in a MongoDB database. Right now, I'm using the native JS fetch() API to perform GET/POST operations on my front end. The GET requests work just fine, but my POST requests seem to not be working. On my front end, I have a form and a handler for form submission like so: handleSubmit(){ let databody = { "name": this.state.nameIn, "quote": this.state.quoteIn } return fetch(
