问题 I'm working with basic HTML/CSS frontend, I currently have a landing page with a form on it that sends some data to a database. When the request is done, it is expecting some sort of response. In this case, I am re-rendering the page, however, I want to replace the form with some sort of a thank you message, something so the user knows that it has sent correctly. I have tried the solution of simply having a separate near identical page with the form removed and replaced, however, this kind of

问题 We are creating a backend for a Twitter view app in Nodejs (Express). I'm thinking of using Twitter Api for login and storing the token returned after authentication to the session and then restoring the session from the cookie when it is accessed again. However, the cookie is blocked when it is accessed again and I can't restore the session information. The browser I use is chrome, but since chrome version 80, SameSite attribute seems to be Lax (sends a cookie when called from the site of

问题 I wanted to know if using Express.js as middleware in a Serverless app (AWS Lambdas) a good idea? My concern comes from the fact that in Express.js there is a mono-function setup and in future if lots of request come in it'll start throttling. Are my concerns valid or I am wavering about nothing. 回答1: The decision between building a mono-lambda and one-function-per-endpoint does not have a crystal-clear answer. On one hand, if you're using cloud formation - you're limited to 200 resources per

问题 I am trying to stream responses to my client using a NodeJS Express server hosted using Azure App Service. However, I noticed that it is not really streaming but tries to send the response as a whole. When the response size is huge (>50MB), the client gets an Internal Server Error , but the server does not throw an error. Further, when I run the server inside a Docker (Node Image: 10.22.0-alpine3.9 ), I see that the client gets the response as a stream even for huge responses. (This is the
