3. Why not go native?
• Walled gardens (app stores)
• Apple/Google/Microsoft take 20-30% of revenue
• Have to write app for each platform…
• … and customise it for each screen resolution
• Less work, faster development, get your product
released quicker!

5. These are the resolutions just for Apple phones and tablets…
7. Use a framework!
Bootstrap http://twitter.github.io/bootstrap/
Suzy http://susy.oddbird.net/
Skeleton http://www.getskeleton.com/
Zurb Foundation http://foundation.zurb.com/
There are loads more...
10. Which should I use?
Funscript Websharper
• Open source
• Completely free
• Can use typescript
definitions
• Client-side only at the
moment
• Minimalist F# to
Javascript compiler
• Open source for open
source apps
• Otherwise commercial
licence
• Server and client side
• Seamless client-server
RPC calls
• Complete framework
11. Developing/Hosting on
Linux
Use vagrant to create a reproducible development
environment.

12. Other great tools
Sass makes CSS fun again. Sass is an extension of
CSS3, adding nested rules, variables,mixins, selector
inheritance, and more. It’s translated to well-
formatted, standard CSS. (http://sass-lang.com/)
LiveScript is a language which compiles to
JavaScript. Syntax similar to F# but dynamically
typed. Useful for accessing javascript libraries without
bindings/typescript definitions. (http://livescript.net/)
PhoneGap lets you turn your HTML 5 app into a native
app and publish it in the app stores
14. Web Apps vs. Native
Native Web applications
Pros:
• Performance
• Native look and feel
• Access whole of device’s API
• May prefer languages +
tooling
Cons:
• Walled garden (app stores)
• 30% of revenue goes to
Google/Apple/Microsoft
• Have to write application for
each platform separately
• Hard to support multitude of
screen sizes
Pros:
• HTML 5 now very capable
• Choose your own
language/framework
• Write your application only
once
• Can still deploy to app store
using products like PhoneGap
Cons:
• Lack of visibility
• Performance often not as
good as native apps
• Javascript sucks
15. Why Websharper?
• Turns out MVC isn’t a great pattern for modern web
applications
• Compositional
• Humans aren’t good at context-switching
• Seamless client server communication

Really depends on your goalsDownsides of native apps:Have to give Apple/Google/Microsoft big chunk of your revenue (app store)Reliant on others (app store approval delays)Have to write app for each platform (android, iOS, Blackberry, Windows Phone)…and customise it for each screen resolution
Have to wait for approvalGive away a big chunk of your revenueLoads of extra workHave to write in a shitty language.
6 resolutions to support just for apple devices. And you probably want to support vertical and horizontal orientations. That’s a dozen.There are around 30 manufacturers of Android devices, each has many different screen sizes.

Anyone who has dealt with web development knows that fighting with different browsers isn’t fun. Use a CSS framework to make your life easier.Show zurb formshttp://foundation.zurb.com/docs/components/forms.html
Dynamic typing leads to bugs – accidental plus in exampleCrazy behaviourWeird scoping
This is a funscript example
Both excellent products with different focus.

Anyone who has dealt with web development knows that fighting with different browsers isn’t fun. Use a CSS framework to make your life easier.PhoneGap also proves access to accelerometer, camera, compass, contacts, file, geolocation, media, notifications and device storage.
Write three times: Somewhat mitigated with Xamarin/Mono but UI often the hardest bit to get rightPerformance: HTML5 probably not a good choice for graphics-heavy games
