I am learning NODEJS addons building
I was able to build a simple application but now I have a problem in connecting to the database using addons and passing query data to NODEJS
Can anyone suggest me what should I do??
I am developing my application using electron so one main issue in electron is it's asar file even though it's protected it can access by anyone and get the password and other stuff to the database so what I am trying to do is create a nodejs c++ addons and pass query and run query in c++ and get query result back to front as a string or something and process them in frontend now I was able to create addon but still couldn't find a way to connect to database c++ there is nothing in anywhere a way to connect to the database in c++ addons actually I don't know is it possible or not but it's worth trying. now I know how to connect to database in pure c++ and when i try to do it in here it can't find libraries.

I am trying to reuse one webapp that's been open sourced a while ago that was written using some Django and ReactJS... Now I am a devops engineer so my skillset when it comes to JS and even Django are fairly limited so I am stuck .. My main problem is that this webapp can run just fine locally.. so I can start it and connect using http://localhost:8000 , but whenever I try and set it up on a server and make it "public" for the internal network it fails with accessing all the JS assets.
I know the problem comes with my webpack configs but I can't sort it out.. Been trying all day but I can't even find the proper documentation since it's using Webpack 2.5.
https://github.com/tsprasath/estate/tree/master/webpack
I am attaching the link to the webpack configs from the repo.. If anyone can at least point me to the right thing to look at, that would be helpful.
Thanks in advance!
I dont think its an issue with your webpack. You are trying to run your react app (which is at client side) from django server. I believe you will need to use some kind of middleware to let django know that it needs to use static files generated for react using webpack. I dont know exactly how its done, but same procedure is followed if react app needs to be served from node/express server.
Or see if this helps: https://github.com/nicholaskajoh/React-Django
I have a HTA tool that connects to oracle database. It's created using HTML,Javascript and oracle as backend.
Javascript connects to oracle database using OLEDB drive. It pulls data and create dynamic rows.
Tool is working but now am planning to convert it as Web Application.
Being a DBA , am not that much familiar with Java and i thought i will explore options in Python.
I have recently done a automation using Python and Selenium. So yes , i know bit of Python. But i have no idea about website using python.
I also don't want to change lot of code. I want javascript to do all the dynamic front-end stuffs.
All i need is interface that can connect to oracle database and pull the information and pass it to javascript function.
Can someone please guide to how to start with.
Thanks.
I don't know Python but if you don't want to change a lot of code, you may consider PHP. It's made to generate HTML code dynamicaly.
It is dangerous to connect to your DB directly by using javascript. Every user can read the JS code in the page and event modify it(sending every value they want).
PHP is executed on the server, it mean that you can check and validate the received value before risking to corupt your DB.
That's why a PHP page between the JS and the DB is better. Python should be secure too but I think it's easier to use PHP because it's open source and well documented.
I wish you a good continuation!
I was able to successfully generate python-flask server boiler-plate code by defining the API in Swagger 2.0.
In the generated code, multiple controllers have been created via which I intend to build connections to MySQL database to generate responses back.
I am facing issues while using flask_mysqldb library to do that. I have defined the mysql connection in the main.py which resides at the root and initializes the application.
mysql = MySQL()
mysql.init_app(app.app)
However, inside the controller, I am unable to use the mysql object to make connections to the database. If I define the above mentioned mysql object in one of the controller functions, I am able to fetch the data once, but it fails the next time and gives me a 500 error.
Please help me understand how can I pass the mysql object from main flask application to the controllers or other custom functions that I define.
Appreciate the help!
Every tutorial and guide show I need another framework such as Express, Angular, Sails, or Koa to connect with MongoDB.
Do I need to learn how to write Middleware, Adapters, and more to get MongoDB to work with EmberJS?
I'm pretty new, and I just finished a simple to-do and web scraping apps. I want to learn how to store it like how I can just write python script, process data, connect to postgresql, save data to the database server.
Can you provide a link to the right source, a step by step process, or tools to research that can help anyone in my position now and in the future learn how to make EmberJS and MongoDB work together without going in circles?
I use nodejs, emberjs, mongodb hosted on heroku.
So basically i'm developing a piece of software that will allow user to call any number he wants right from the website. So i need some help in choosing the correct platform or semi cheap service to use. I guess i need a solution with open API because i want to make a db entry (want to record duration and date) for every call made from website.
I've started research and stumbled upon couple of open source solutions: Asterisk and FreeSWITCH. Trying them out right now, but i still have poor understanding of how SIP works. If it will be a softphone will the user have need to install it on their pc or there are server solutions
One possible solution that works with any SIP server is to use PJSUA Python bindings and to implement in Python a basic softphone. Thus your web application will be seen by the SIP server just as a regular soft phone and the server configuration is much easier.
