问题 I'm using an ngx-awesome-uploader to add my images to angular to send to backend. I'm trying to send the file to my nodejs backend, but it keeps returning {} on backend where the file should be. Never worked with files before, but I'm gonna take an educated guess and say that should have something in there. On the frontend it looks like the file is there to be sent because console.log(fileUpload.file); output BACKEND OUTPUT File Upload Section { file: {}, fileName: 'image.png' } But is empty

问题 I am a newbee to the express nodejs applications. I want to make a todo list. This is how it looks so far. My question is when I add a todo, it takes some time to show the change since it reloads the page. How can I see the change in realtime without reloading the page. Thanks in advance. in tasks.jade h1= title .list .item.add-task div.action form(action='/tasks', method='post', id='12345') input(type='hidden', value='true', name='all_done') input(type='hidden', value=locals._csrf, name='

问题 I would like use nodeJS to refresh my view, every time a function has made changes to the database. If we take MEAN-stack as an example, I don't want to send an $http-request every x seconds to check if changes have been made to the database. I would like the front end to get notified automatically and then update the view. What are best practices for this? I would use some kind of Oberserver pattern in the server side, but do not know how I could notify the front end with that. 回答1: To get

问题 (* superuser does not like this question, so i post it here *) I have a set of scripts in Octave to undertake a machine-learning algorithm. I have also a website by mean-stack. My question is whether it is possible to integrate this Octave code into the site web, either front-end or back-end. Do I have to rewrite everything in JavaScript or nodeJS? 回答1: You have several options. From a backend point of view: use standard cgi solutions. Octave has a cgi package you can use. This would be my
