I am new to web development. I want to develop a web application using angularJS, nodeJS, Express and couchdb. The registered user will be given some tasks. So the app must maintain data of tasks assigned to a user and tasks completed by the user. It should also maintain the data of users when they register for this app.
**I am able to access data(user name,tasks assigned to user,tasks completed by user) from couchdb through nodejs. But I don't know how to make angularjs access the data accessed by nodeJS and display it on web page. I would like to know how to access that data and display it on webpage.**You can take tasks as repairing a chair or something.

I am learning web dev and I am planning on developing a simple web app using React: a decision matrix tool.
I need users to be able log in and save their matrices under their profile so I prefer to not use LocalStorage and thus learn more about databases. I am thinking of using JSON as the data format and I will also need to store basics user data for login and their profile.
I wonder how to tackle such a project since so far I have only been using GitHub Pages to host my static websites. Most of what I find by googling seems confusing or irrelevant for such a small-sized project.
My questions are:
What is the simplest way to store, access and edit JSON data as well as user data for a web app?
Are there any simple databases that can be “hosted” together with the app files on a server? Not sure if the question makes sense but I don’t understand where the database is.
What article or resource would you recommend to understand the concepts for data storage?
Ideally you would want to create a backend server using any language/framework e.g nodejs, java, django, php etc and expose the required data through APIs. But, if you don't want to create a separate backend app you can use Firebase database Firestore to save and fetch all of your required data. You can even use firebase hosting to deploy your app. Moreover, firebase also have their Authentication service which you can leverage for your app's authentication.
According to this answer, I want to use an offline first db inside my electron app. I nedd that the users are not able to directly modify the database, but they can only read data using the UI. The data needs to be synced with a master remote client app that will add and modify data. Can anyone suggest me a good database library to do this?I have a pusher account and an heroku one, that can be used to pass the data between the clients, but first I need a way to store them into the app
i'm working on building my own backend and an API for my project which is currently running on firebase. now the problem is that once the project grows it'll be expensive for me to continue using firebase as there will be a lot of data exchange and traffic and up to million users signing up. how do i migrate from firebase to services like DigitalOcean considering that my authentication data with current users its in firebase.
There is no public method in Firebase Authentication to retrieve a list of users. But there is a process to export the user data, which we're looking to clean up in a future release.
If you're having problems decoding the exported user data, post a question with details or reach out to Firebase support for personalized help in troubleshooting.
I am having a web application built using JAVA spring which has API feature to read and write into database.
Now i have to develop an ionic mobile app for the same application. How to read and write data into database.
I know Firebase and other alternatives can do the job.
But i need my own API code(written for web app) to be used. Is there any way to achieve that?
I guess calling the respective API when the web application is live is achievable.
But how can i achieve that while developing(When the web app is under construction)
Well depending on how you set up the API this could become quite difficult.
You're saying/guessing that you can call the API when the webapplication is live. This makes me assume you've created a REST API? Or did you create a Spring MVC application?
If the webapplication is directly linked to your Spring application (f.e. going to localhost:8080/my-profile shows a page (not JSON) of your profile) then I'm not sure if you can achieve the above mentioned target.
If you get a JSON response, or are somehow able to retrieve it from the webpage, you can just simply call (in typescript:)
this.http.get('http://localhost:8080/my-profile').map(response => console.log(response.json() );
Else, you probably will have to create a basic REST API (check out Spring boot for a 5 minute setup) and provide it, either with hardcoded data or connect it with your database.
Based on this question Sync data between Android App and webserver, I would like to know if there is an existing javascript (not native) SyncAdapter for an Ionic app (just angular is also ok). If not I would like to get some guidelines to write one in the following aspects:
How to maintain coherence between app data and server data
How to manage app offline situation
Recommended interval to refresh from server
Battery saving management
