🧐 About

Write Once deploy on multiple API_LEVEL as minimum.

You write using API_LEVEL 3.0 then you can Change min API level of your project on the fly just with one command and same codebase.

* Although the functionality is almost complete. Testing is not yet complete and expect to find bugs/issues. You can consider this library in beta.

* Please report any issues found here or create a pull request. Thanks in advance

🏁 Usage

``
npm i zeppos-cross-api
npx zeppos-cross-api --api-level=X.0
`
where X is 1, 2 or 3 according to your project ( you still write your code using API_LEVEL 3) and can change the min API again as easily as running above command again with new API_LEVEL

then replace each instance of '@zepos' with 'zeppos-cross-api' and you good to go

use try and catch with new functionality with sensible fallbacks for new APIs see status for details. for example

`
try {
const player = create(id.PLAYER)
} catch (error) {
do something else
}
`
In addition to the modules in 3.0 There is four 5 new modules (sources here and here):

1. data-conversion contains very usefull functions like str2bin to convert from string to ArrayBuffer and bin2str for viceversa.
2. device-polyfill import in your app.js if you want to use promises and setTimeout/setInterval without worrying about api level
3. zml-base-app modified version of ZML base app
4. zml-base-page modified version of ZML base page
5. zml-base-side modified version of ZML base side

zml is recommended for usage for fetch, httprequest and other side service APIs but take care that

1. Image Convert
2. Download
3. FileTransfer

are only avaliable in 3.0+ and would throw unsupported exception in other api levels.

:dart: SUPPORT STATUS

For each of non-supported function we either have

1. ERROR => function throws an error
2. NOOP => function does nothing

For each module of each API_LEVEL there is 5 level of support:

1. 🟩 FULL
2. 🟧 PARTIAL
3. 🟥 NONE (ALL are ERROR)
4. 🟥 NONE^* (ALL are NOOP)
5. N/A (not yet implemented)
