Hey! I am actually in internship and have an app to create for my structure. It will be an intern app which will allow crud dashboard actions with some data provided by the use of an API of one of the structure partner and make a correspondence to data contained in a private database. Since it's an intern app, I thought about Electron for a desktop app because I did a lot of web with Laravel and the structure goes more for the desktop app. But it will be my first occasion working with this tech.

Is Electron a good choice? Wich ORM should be more complete and adapted to this between Sequelize and TypeORM? (Database will be MySQL) Some charts will be displayed in the app. Is there a library (preferably without jQuery) that suits this stack?

Thank you !

Sequelize Alternatives & Comparisons

What are some alternatives to Sequelize?
A super simple tool that turns any image (including PSDs) or sketch into interactive prototypes for any device. Powered by Dropbox.
It is a simple, flexible, and powerful SQL database access toolkit for Ruby. It includes a comprehensive ORM layer for mapping records to Ruby objects and handling associated records.
It supports both Active Record and Data Mapper patterns, unlike all other JavaScript ORMs currently in existence, which means you can write high quality, loosely coupled, scalable, maintainable applications the most productive way.
Let's face it, writing MongoDB validation, casting and business logic boilerplate is a drag. That's why we wrote Mongoose. Mongoose provides a straight-forward, schema-based solution to modeling your application data and includes built-in type casting, validation, query building, business logic hooks and more, out of the box.
Prisma is an open-source database toolkit. It replaces traditional ORMs and makes database access easy with an auto-generated query builder for TypeScript & Node.js.
