Alternatives to Entity Framework

What is the best way to increase your income as a freelancer in 2019? What frameworks should be the best to learn? React Node.js Docker Kubernetes Sequelize Mongoose MongoDB ExpressJS hapi Based on trends I've picked up a JS full stack. If you need to work under startups you may replace React with Vue.js . If you want to work in outsourcing Angular 2+ may be better.

What is your opinion?

Hey Mohd. Those are pretty good areas to start with. For front end, focus on getting really good at JavaScript and React. Specifically, learn how to manage state in complex apps. You might want to learn Redux to help with this. Make sure you're using semantic elements in your JSX and get good at using flexbox in your CSS 3. I wouldn't necessarily use Bootstrap, it's good practice to build components yourself. A good exercise is to try to replicate a website like StackOverflow or ProductHunt from scratch.

On backend, ExpressJS is a good place to start. Learn how to build semantic REST APIs that pull data from a database. MongoDB is fine, but I would suggest using Mongoose along with it to avoid nesting objects too much. You could alternatively use a SQL database like PostgreSQL, with an ORM like Sequelize to manage the data.

Merging Django ORM with SQLAlchemy for Easier Data Analysis (Video Inside)

Development of products with Django framework is usually easy and straightforward; great documentation, many tools out of the box, plenty of open source libraries and big community. Django ORM takes full control about SQL layer protecting you from mistakes, and underlying details of queries so you can spend more time on designing and building your application structure in Python code. However, sometimes such behavior may hurt - for example, when you’re building a project related to data analysis. Building advanced queries with Django is not very easy; it’s hard to read (in Python) and hard to understand what’s going on in SQL-level without logging or printing generated SQL queries somewhere. Moreover, such queries could not be efficient enough, so this will hit you back when you load more data into DB to play with. In one moment, you can find yourself doing too much raw SQL through Django cursor, and this is the moment when you should do a break and take a look on another interesting tool, which is placed right between ORM layer and the layer of raw SQL queries.
