Many mobile app frameworks mix JavaScript / CSS / HTML5 concepts with native
|
|
|
|
|
extensions and libraries to create a hybrid development experience. Developers
|
|
|
|
|
well-versed in web technologies can now build actual mobile applications that
|
|
|
|
|
run on iOS and Android!

|
**The ecosystem has broken backwards-compatibility many times!**
|
|
|
|
|
|
|
|
|
|
iOS and Android, as well as the underlying JavaScript frameworks, make breaking
|
|
|
|
|
changes regularly. The demos were tested against emulators / real devices at
|
|
|
|
|
some point in time. A framework or OS change can render the demos inoperable.
|
|
|
|
|
|
|
|
|
|
MacOS is required for the iOS demos. The Android demos were tested on MacOS.

|
The ["JavaScript Engines"](/docs/demos/engines) section includes samples for JS
|
|
|
|
|
engines used in the mobile app frameworks. SheetJS libraries have been tested
|
|
|
|
|
in the relevant engines and should "just work" with some caveats.
|
|
|
|
|
|
|
|
|
|
Demos for common tools are included in separate pages. Each demo section will
|
|
|
|
|
mention test dates and platform versions.

const listyle = (item.customProps?.icon) ? {

listStyleImage: `url("${item.customProps.icon}")`
|
|
|
|

} : {};
|

return (<li style={listyle} {...(item.customProps?.class ? {className: item.customProps.class}: {})}>

:::note Recommendation
|
|
|
|
|
|
|
|
|
|
React Native is extremely popular and is the recommended choice for greenfield
|
|
|
|
|
projects that can use community modules. However, its "lean core" approach
|
|
|
|
|
forces developers to learn iOS/Android programming or use community modules to
|
|
|
|
|
provide basic app features.
|
|
|
|
|
|
|
|
|
|
The original Web View framework was PhoneGap/Cordova. The modern frameworks
|
|
|
|
|
are built atop Cordova. Cordova is waning in popularity but it has a deep
|
|
|
|
|
library of community modules to solve many problems.
|
|
|
|
|
|
|
|
|
|
Before creating a new app, it is important to identify what features the app
|
|
|
|
|
should support and investigate community modules. If there are popular modules
|
|
|
|
|
for features that must be included, or for teams that are comfortable with
|
|
|
|
|
native app development, React Native is the obvious choice.
|
|
|
|
|
|
|
|
|
|
NativeScript is not recommended at this time. There are known bugs related to
|
|
|
|
|
binary data processing. The demo only supports plaintext file formats like CSV.
