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.

I am learning React.js and new to web programming. All along when doing my own projects it's only for my own use, and hosted on localhost:3000. (i.e. one user).
I have a question about multiple users which I don't know if it's specific to React or just general web programming, but I can't seem to find it online, as perhaps it's too basic? And sorry if it's a very basic question. I will have to make an app for internal use for a team of less than 10 people soon, and it will be hosted on a local server accessible by this team.
Would the code be any different in terms of how I write this app? (say, it's just a todo list where users are able to add and remove items)
Specifically, how do states work when there are more than one user? Are they stored on the user's local device?
If one user clicks a button and sets some state from true to false for example, does it re-render for the other users too? Or do all users get their own instance of the app?
I would also appreciate it if you would know what kind of resources I should look at for this question, as I would like to read more in-depth about it.
well, all the apps run on each user own machine independently. State, actions and all other(whole app) are happening only one user own machine. So there is no interaction if I may say so out of the box between different machines(users). You may achieve that with help of some sockets connections( for example instant chat)
Ok... I am so confused. I am new to React Native and I have created a simple mobile app that shows a list of news (containing a specific image, title, and description). I have a lot of experience with programming most of which comes from game development. I have created many games and I am familiar to cloud storage systems that you update and retrieve data.
Right now I just have a local json file with an array of 'news' Objects and then I loop through this array to show the news posts. Basically, I want to move this json file to somewhere online where the app just retrieves it. This would make it so that the News json file could be edited in order to change, add or remove new news. So, I don't need account or anything. I don't even need to be able to set/update data from the app. I just need a place to store images and files that can be retrieved from the app.
I have tried using the common react native data base systems like sqlite, realm, mongodb, and firebase, but must not understand how they work because they make no sense. Also, it seems like when making a mobile app all of these services require you to setup a backend and start a server, which from what I can tell doesn't work on mobile... It seems logical that there would be a global data base that I could store storage on and just receive it by a simple fetch or network call. Am I totally crazy here ?:) Any help or guidance is super appreciated. Thanks.
I created a web app in mvc 5, using angularjs as controller but the problem is, all my code of my app will be shown if i click on inspect in google chrome, i don't want to show my coding to any user, how can i prevent the user to view my coding,
and is angularjs is less safer then c# and is there any way (by coding) to prevent all the users to view our code in insect element
i know this is not exactly related to coding, but my app has the
transacion related to banks
This is normal with any web application that depends on client side scripting language.
JavaScript should be only used to handle the user interface flow and interactions, the business logic and persistence should be handled in the back end.
You should never trust any data coming from the UI, always validate it before retrieval or saving.
As for the code that is visible, you can always minify the JavaScript files, this will make it at least harder for anyone to inspect and understand the code
I've recently switched from developing wordpress sites to learning angular, express, mongo, passport etc etc. Wordpress obviously provides a (relatively) simple interface whereby the user can manage their own page content.
My question is, is there a standard procedure for achieving this using the above technologies? I'm currently building my first site proper using MEAN for a friend and I want to give her the means to go in and update images, text, add pages, remove pages etc etc but via a user friendly interface.
I've a feeling I'm going to have to build it myself but before I launch into doing that I was wondering if there was anything glaringly obvious that I'm missing?
Thanks in advance
I want to implement a web-based API (using ASP.NET Web API 2) and consume it by the client Side library (Sencha Ext JS).
My application should include
A simple user registration form.
A login page for admin.
CRUD operations for users' submissions.
Notes:
I do not want to include any backend code (i.e C#) in the we application, I want to implement it using the HTML/Javascript only, that is Ext JS.
I want the Web API to be RESTful.
I want to protect admin pages.
I want to use the SQL Server to store users' submissions.
All of that requirements should be implemented using the ASP.net Web API 2 and Ext JS only.
So far, I did initial search and I got a lot of learning for either the ASP.net API 2 or the Ext JS. But I couldn't have a guide that help me to fulfill the above requirements or help me to have both technologies work together.
Pleas help me on either way.
Or generally, can you help me get started work in combining both: Asp.net Web API 2 and any client side that consumes it, such as Sencha Ext JS or any other client side. It is not necessarily to be Ext JS.
Thank you so much.
Thanks to StackOverflow.com
If it were me, I'd use the DirectAPI for asp.net https://github.com/elishnevsky/ext-direct-mvc
You create webapi controllers, just like you normally would. The only difference is the the controllers that need to be used by EXT should inherit from DirectController.
If you follow the directions on that page, you'll end up with a globally available proxy object that matches the name of the controller and the public methods hanging off of the controller become methods of that object.
That is, server side controller MyAwesomeController with method DoSomething() becomes MyAwesome.DoSomething.
If you attribute the method as [NamedArguements] you can create methods such as
DoSomething(int id, int foo)
and pass from javascript as DoSomething({id: 20, foo: 30});
Since it is still just a controller, you can attribute permissions and return json as you would in any other situation.
If you get stuck, use the debugger and spend the time to figure out what's really going on. This all works in 4.x and I've tried it in 5.x and it still works there as well. But I wouldn't jump into 5.x just yet as there are still several bugs that need to be worked out by the sencha team before it is ready for prime time.
ExtJs has a REST proxy for the data. So what you try to do should be possible. The proxy can be configured and be finetuned.
I used the JSON proxy. ExtJs has very powerful filter and sort capabilities, both server and client side. In my experience difficulties arose when filtering and sorting server side. There is only sparse documentation on how the parameters are passed and which configurations have what effects.
Since you also develop the REST api, you can adapt to those details. You just have to do some research.
Here is not the place to ask about guides. For Asp I cannot help you, I never touched it. If you use ExtJs, you are free to choose you backend. For ExtJs, the start is pretty straight forward :
get Sencha cmd and generate a skeleton app.
follow the tutorial
create one file per class definition.
the API docs are great. If you still lack something SO is great too.
what you have to find out by yourself is the exact way parameters are passed to the backend and how to format the response.
