Web vs Desktop App Development

Developer's Day 2021 - Qualco

Why web?

1. easy to deploy/update
2. can be hosted both on premise & on cloud
3. cross platforms
4. apps accessible from anywhere
5. easier to attract clients
6. use of new & upgraded technologies

But

1. Security is harder
2. JS is not the most structured language so it's harder to maintain

How do we select a framework?

1. Established web technologies
2. well documented technology means we can easily educate other engineers
3. abstraction/encapsulation
4. reusability
5. customization
6. performance
7. ability to write unit tests

Technologies

JS

There is no single framework that has all the solutions

• react (fb)
• angular (google)
• vue (ex google engineer)
• ...

Select between

• b2b (business to business)
• b2c (business to consumer)

Typescript

• < Microsoft
• compiles to plain JS so it's compatible with all browsers
• object oriented (client side as well as server side dev)
• static type checking (check variable type on compile time (like Java), expressly indicated by programmer or (e.g. OCaml type reference is used (compiled)
  • the opposite is called dynamically typed language (like Python, JS, Bash) - mostly scripting languages (interpreted)

Angular

• offers tools & design patterns to build your project in a maintainable way
• components are decoupled
• testing is at heart
• mobile & desktop ready
• BUT: harder to learn because different ideologies

ASP.NET core

• cross platform
• high performance
• open source frameowrk for building modern, cloud based internet connected apps
• helps build web apps & services, IoT apps, mobile backends using .NET APIs.

Keep in mind

• change SDLC to introduce pen testing & security reviews
• invest in technical documentation & training when transitioning from desktop to web as it can be daunting for devs
• define early how to measure success of a platform (e.g. unit tests on time of loading etc)
• select appropriate IDE for development
