I've recently begun developing with NodeJS and ElectronJS to create some pretty nifty cross platform software. I want to take it a step further and integrate some database functionality.
While I'm aware that there are mysql packages available to install, I cringe at the idea that anybody can just unpack my asar.app file and see all of the connection details, including username, password, database name, table name, and other sensitive content that you really don't want to expose to people clever enough to break into your app's source code.
I've tried searching extensively on solutions to this problem, which I was surprised to find very little about. How do WhatsApp and Slack secure connections to their database if they were also built with ElectronJS?
Any and all resources are greatly appreciated. I basically want to be able to connect to a production server SQL database in an ElectronJS app without leaving some security backdoor to anybody who cracks the ASAR file.
Thank you!!
For this scenario, I suggest you to use a RESTful web service architecture. Basically you need 3 component, RESTful web back end, client application(your electron) and the database service( see the following image ; source:phppot.com) .For this I suggest you to use nodeJS backend and create a webservice using expressJS . You can define Restful (GET, POST,UPDATE, DELETE) API for each services.
For ex: To get some data from your db, you can send a GET request to the following path <yourdomain>:<port>/api/v1/getyoursomthin using your electron app. Your express app process the request and get the relevant data from the data from the database (Tutorial). So your app can get the respond from the server and display to the user. I will add link to some tutorials. You can find and learn more by google :)

So I am currently learning react and webpack so that I can implement it into my current site. I already have an established phpmyadmin database that pumps out information that I want to appear on my site but I cant figure out how to hide my username and password to the database when programming it. I am used to using php to interact with my database bus since react is purely javascript I am not sure what to do.
You need to have a server running that talks to your database and to your react app. It sounds like you might have this in the form of a PHP application. Your PHP application will need to expose data over HTTP endpoints that you can then fetch from inside of your React application.
This tutorial: https://www.techiediaries.com/php-react-rest-api-crud-tutorial/ would be a great place for you to get started.
I agree that you need to "have a server running that talks to your database and to your react app" as the accepted answer states. On the other hand this does not mean that you have to code it from scratch.
If you don't want to program PHP for the back-end, then you may as well configure software from the list of 'automatic APIs'. An automatic API is "software that turns your database into a REST/GraphQL API".
I'm the author of PHP-CRUD-API, which is an 'automatic API' and I think it suits your needs, but you may as well use any other software from the above list.
I'm developing an app in Ionic 2/Angular 2/Cordova and I need to implement this behaviour: storing data in the client app and download data of each client to the main server database, periodically, as soon as the mobile data network on the device is available.
What is the current best practice to do this?
I would think SQLlite database on the app, mySQL database on the server and a web service for the app to call and send data. There is something pre-built to do this? (coding this from scratch seems to me like reinventing the wheel)
EDIT: after some researches I've found something called PouchDB (son of CouchDB) but I'm not sure it is sufficiently used/supported by the community to use it and hope to find help online in case of problems
Is it possible to build a realtime app using AngularJs with a mysql database?
I've been reading thousands of tutorials, but they are all focused on express, nodejs, etc.. didn't found any documentation on wheter it's possible or not. I tried to take a look at the socket.io docs, but still didn't found anything relevant to this question.
I didn't tried anything yet because of this. I use a webApp based on AngularJs on a apache server (local).
Where should i start to be able to build a real time app using these tools i have?
Do i really need to use a node/express server?
What are the main consideration i need to do before taking this step?
Is there any documentation i should read?
I need to do this real time because it involves product orders, call center, ticket system, etc.. So everytime there is a new ticket is opened/changed, new order arrives, etc.. I need to make the user aware of this, without the need to refresh the page.
Or if someone could give me a further explanation of this concept and how to get started, it will be great.
You can run angular on top of any backend, although most examples push towards REST. If you want your app to feel like a real time application, using WebSockets is a likely improvement.
WebSockets play nice with Angular, look at https://github.com/wilk/ng-websocket for example. A back-end in Node will work, but many other backend techs will do equally well.
Here is a decent tutorial using MySQL, NodeJS, and Angular: https://codeforgeek.com/2015/03/real-time-app-socket-io/
I recommend that you keep using a webserver like Apache (my personal preference is Nginx). You can proxy API and socket requests to Node, and serve static resources for the app from a folder.
Check out https://httpd.apache.org/docs/2.4/mod/mod_proxy_wstunnel.html if you stay with Apache. Check out http://nginx.org/en/docs/http/websocket.html is you go for nginx.
Without a webserver, you'll have to either:
serve your static resources with Node (polluting your server project with client code), or
work with different ports, risking the app becomes unusable in client environments, or
work with different domains, giving you a CORS head-ache.
Although I don't have much experience with Node, MySQL with Node.js should help you out a bit.
You'll want to move away from Apache if you want to do websocket stuff with Socket.io
Yes, it is possible to create a software with AngularJS in the front end and any other server side language that speaks to MySQL. Few months back I worked on a software with Java Spring Framework in the backend with MySQL database and AngularJS with bootstrap in the front end. You could start by following the MVC pattern, where your views can be served as AngularJS and your Controller can be in any server side code, with MySQL database.
I'm trying to create a real time web application with NodeJS with an MVC layout using the Express framework and MySQL as my back end data store.
The problem that I've run into is that I can't find any good examples or tutorials on how to use Socket.io (or any other web socket platform to pass information in real time from the database to the web application. The specific problem is getting any new update to MySQL on a specific table to pass that information to, so that if new information is added to the database by a second client connection it will update on the first client connection as soon as the information is added.
Does anyone have any ideas on how to get socket.io(or another websocket connection protocol) and mysql to work together to achieve this? Any code example's or pointing me to some websites that have documentation on this topic would be appreciated.
Thank you!
I am developing an education app for Kids.
The application is going to contain pictures, stories and video as well.
Including all above contents in the app will surely bloat it and hence i would like store all data on a server that will be accessed by my app.
I haven't used any remote databases (like MySQL or Oracle) with any other iOS app. In fact i am a newbie in developing such kind of apps. Can any one point me to a sample
Connecting to a remote mysql is really not recommended.
The security here is critical.
You should create a webservice and my advice to you is to make sure that the access to the webservice is restricted
The webservice can be your own "protocol" or any other well known protocol like SOAP
By your own I mean, json, csv .... or whatever.
Edit 1
The technology of your webservice should be dependent on many things.
If the system is small, and the code needs to be update very often, I would suggest to do it with PHP and some small(!) MVC framework like CI.
But if its a large system with needs of ACL (access control list) I will probably choose java with spring...
I suggest that : Do not connect to / use database directly from user application. It may causes serious security problems and your app should have native SQL drivers to connect db.
So, create a web service that receive queries from the application and response in XML, JSON or some other strings that easy to parse. This will be much easier than embed native APIs into your apps.
