I would like to know the structure of a typical NodeJS app, because the more I read and see the projects, the more confused I am, specifically for questions like these (or even more after I updated this question): Take the MEAN stack for example, from what I know, NodeJS and Express take care of the server part, providing the server interface, etc. MongoDB and Angular are pretty straightforward.

MEAN Stack File uploads

My main problem right now is getting the file upload to work, because what I want to do is receive the file from the form into the AngularJS Controller and pass it along with more info's to ExpressJS so I can finally send everything to MongoDB.

How to deploy MEAN.js (Node.js) application to Production environment

阅读更多关于 How to deploy MEAN.js (Node.js) application to Production environment

MEAN.JS stack proposes the "grunt build" task for preparing application to Production. Unfortunately there is a lack of information about next steps. Actually it's not clear how to deploy the application to production and how to launch it. Question #1 What must be configured in the project in addition to changes in the config/env/production.js? E.g. how to work with custom fonts? Question #2 Ok. The code deployed to Production (via Git, rsync, etc). Is it enough to run it as $NODE_ENV=production node server.js& Roman Podlinov I recommend to do the following steps for deployment to production

Angular ng-repeat filter on subarray

阅读更多关于 Angular ng-repeat filter on subarray

问题 Using Angular, I'm trying to filter using ng-repeat on FactorName given the following schema. Filtering using <... ng-model="query.Factors.FactorName" ...> doesn't work (not surprisingly). I haven't seen literature on anyone trying to filter in this way. Does Angular support filtering based on a subarray element property ? [ { "Name":"1", "Factors":[ { "FactorName":"FactorOne", "Type":"SomeType" }, { "FactorName":"FactorTwo", "Type":"SomeType" } ] }, { "Name":"2", "Factors":[ { "FactorName":
