Pre-loading heavier modules

[jmiecz]

Hello,

Is there a way to pre-load some modules? I've noticed that the UI thread will sometimes lock up for a couple of seconds while Koin is grabbing all the depenicies.

An example would be, having an HttpClient that is used among different services. When you call on the first service, the app will hang while it creates the HttpClient for the 1st time but any calls after will result in 0 delay.

Hello @jmiecz,

not available in last 0.9.x version.

For 1.0.0 release, the eager parameter will be added to definitions & modules, to allow a definition/module to be created at start.

[jmiecz]

@arnaudgiuliani Do you happen to have an ETA of when 1.0.0 will drop?

[arnaudgiuliani]

Target 1.0.0 release is for September: https://github.com/Ekito/koin/milestones

There will be some beta versions before to let you test it.

Cool, thanks @arnaudgiuliani !

Side question, will eager help with the frame skipping?

[arnaudgiuliani]

Frameskip comes from processing in main thread.

Preloading stuff and make load in background thread will help you 👍

[jmiecz]

Sounds good, thanks :D

make load in background thread will help you @arnaudgiuliani

How is it possible to load Koin dependencies in the background thread? Something that can be accomplished with Coroutines or RX?

[arnaudgiuliani]

@johnnycube all definitions are lazy by default. We are currently working on the eager tag.

We will have:

• a createEagerInstances boolean parameter from startKoin() to directly create eager definitions at start
• a createEagerInstances() function to call, to create eager instances when you want (and when you don't to create it directly at start)

You will be able to use this last in a background thread.
