Background
I am attempting to develop an AngularJS app that is to be hosted as 'offline html' as part of the Resco MobileCRM software. This software provides offline access to CRM data via its own javascript libraries and this is working fine. I am also able to get a very simple angularjs application working, in terms of retrieving and displaying the data.
The AngularJS application is uploaded to the CRM using the Resco interface and then is download to each client machine via the resco software. The actual files end up in the users AppData folder on each client machine.
Problem
When I introduced routing to the angular app, either using ngRoute or ui-router, I am getting Access Denied errors. The resco software uses the underlying browser, which in my case is IE11. I have narrowed down the error to when angular is attempting to load the partials for the routes.
The offending code is below (angular.js v1.3.15 line 9805)
xhr.open(method, url, true);
From my research, it seems like IE believes I am attempting a CORS request, however I am just attempting to load a file from disk.
Various posts suggest I add the site to 'Trusted Sites', however I am not actually accessing another site. I also cannot host this on a web server as the whole purpose is to have this angular application accessible offline within the Resco MobileCRM application
I also get the same error if I navigate to the AppData folder and run the angularjs application directly from there (i.e. not in the resco application).
Other posts have suggested that I need to replace the XMLHttpRequest created by Angular with XDomainRequest but I am reluctant to change the angular library, especially if I don't understand why.
Would appreciate it if anyone could shed some light on why this is happening and how to fix it.
I have confirmed that this is not possible on any of the browsers. You cannot make xhr requests to files served locally from disk.
I got around this problem for directives by loading my 'partials' in to script tags and referring to the id of these script tags in the directives.
I did not try that with ui.router or ngRoute and instead opted to redesign my application in to a number of smaller application as they did not need to share any context

I was wondering if anyone could help me at all.
I posted a previous question in regards to this title but I didn't receive much of a response (probably due to lack of information).
I started out with an Ionic Application and built the view files using state URLS to navigate from page to page in the WWW folder. I've then created corresponding controllers for the view files, for basic calls and functionality that I want my app to do in the front-end via Ionic.
My question is how do I setup MongoDB + Mongoose so I can have access to the models I have created?
I have scoured the internet but to no avail, I mean I know there is no set way to define a model within this type of application but some general guidance would be really appreciated.
I understand that when building an application with Angular you're essentially building 2 applications, the front-end where your CSS, JS and HTML goes with the front-end frameworks on top of them.
Then the backend application that runs the server, stores data and runs the business logic. This is where I have created the User Schema model for my application and have inserted a document into my database via the MongoDB shell whilst running mongod.
However I also created a users.js in another models folder in my front-end where I'm returning a resource following a url with either a get, save, query, remove or delete.
First of all I would like to say I'm relatively new to building mobile applications so this may even be entirely wrong and secondly up to this point I get lost as to what to do in my application.
I have tried setting up an express server in my app.js file and I can connect to it via my terminal as it is listening on the port number, but in the browser it is coming up with cannot /GET.
If you need any more information please feel free to ask, I know I haven't really gone into any technicals, but I'm really not sure even if I'm asking the right questions to begin with.
Thank you in advance.
Ok so I have looked around and cannot find the exact answer I am looking for. When developing a Sails app (which I am new to) it appears that by default it creates its own frontend using EJS.
Is this correct?
If this is correct then why is there an npm for sails generate frontend
If I want to use an Angular frontend is sails-generate-frontend-angular the best route to go?
Thanks!
First you need to separate server templating (EJS) from angular.
Just because sails defaults to an EJS template engine does not mean that you can not still put angular is your asset library and create and angular app. EJS is (the default but not the only option) what sails uses as a programming language for building its templates on the server that then get delivered to the client. Angular templates are used once delivered to the client to display information and perform tasks specifically already in the client machine.
1.) See above
2.) Sails-generate-frontend helps to setup your asset pipeline. It creates grunt tasks to copy image files and setup your javascript libraries such as ANGULAR.js, jQuery ect for use in your front-end.
3.) It could be. It depends, what a lot of people do is setup 2 projects. They use Sails as their API and then setup a second project for their Angular app (especially if its a SPA).
If instead your just using angular is specific places in your app (think jQuery style), then you would use a something like generate-front-end to take the angular library from someplace (like bower_compenents) and place it in your assets when you lift your app. It also makes it avaiable so that it can be placed in your html to be included in your app.
I on the other hand, use sails templates (I use Jade instead of EJS) to create and modify my angular templates on the server before they reach the client. This is a slightly advanced practice and can get confusing if you don't understand the difference between generating html on the server vs client.
An alternate method of thinking about this would be creating your index page on the server. This page would include your css and scripts. It would possibly be the only page on your server and everything else would be angular templates rendered on the client asking for JSON calls. In this scenario you would be using SAILS (ejs, or jade or whatever) to render only a single page INDEX.js and that might be the only server template you have.
However, this being said. Sails ships with this stuff already. You don't need sails-generate-frontend. Its is already inside a standard sails app.
I am having an issue where my grunt build file is building correctly, but the website I'm working on is not getting all of the css files. It is only getting the master.css file. I'm using nodejs, with kraken, on top of express. I can't tell if there is some configuration option I need to change, I don't really know where I would do that.
For anyone interested, the issue was with the changing structure of the project. Going from angular to a dustjs w/ backbone combo changes the project form a SPA structure to a multi-page structure. This makes a huge difference because now instead of sending everything at once we are sending pages as they are needed, this also means that when a user switches to a different view, the server will be building an html version of that view and sending it back as fully fleshed out html. When the server builds the page it has access to the file structure, which means that the build folder that was necessary for the angular project, is no longer necessary.
I am currently working on a Java based Maven project that has a REST backend module and using angular JS as a frontend that uses the backend for data. The 2 modules are named "rest" and "web" accordingly and are deployed as 2 separate war files to a glassfish instance during development. The glassfish is on a different machine.
My problem is that this is kind of slow, especially when developing the angular based frontend. Fix a minor spelling mistake, package, redeploy. Not that slow but every character change or fiddling with angular is another 20-30 seconds lost.
One thing I tried is to directly load the files from the source directory into the browser with file:// tag. This is OK as long as it tries to call the REST backend which fails due to CORS (I don't remember the exact error message, it just doesn't work). This happens a lot so it's a no-go.
I'm open to every kind of solution to develop angular in a way that I could see my changes instantly instead of deploying it every time? Much like the guy does in the egghead videos.
I would recommend breaking your Angular JS application into its own separate project, this would be a new HTML5 project on Netbeans. That way you can focus on pure backend and frontend development in their respective projects and you do not have to manually separate the war files. This link will help you to get CORS working if you are defining your RESTFUL services with Jersey Access-Control-Allow-Origin in ajax call to jersey rest web services. Or you can just mock the data out in the front end project.
I´m trying to integrate a Blueimp Jquery File Upload plugin in my application.
My application has an AngularJS front-end running in a Node.js server and a Rails API backend running in a WEBrick server.
I would like to clarify which is the best practices to store the files? In Angular (this case Node.js) server or the Rails one.
Thanks,
Roberto.
I'm working on an app that has the exact same layout as yours and I came to the same question.
Since I'm trying to separate the back-end and front-end completely and have all the work with the db and files done in the back-end, I found that it's better to save the files in Rails server. That also gives you an option to do background operations with files (using sidekiq, for example), without making users wait for completion in the front-end.
There are lots of tools for file upload from angularJS to the server (Rails), but I personally found angular-file-upload directive easiest to understand and implement. I recommend you check it out.
I hope it helps,
