[mvi]: https://hannesdorfmann.com/android/model-view-intent/ "Model-View-Intent (MVI)" [sam]: https://sam.js.org/ "State-Action-Model (SAM)" ## Naming The semantic distinction of external triggers, inputs, or _events_ (as in _event sourcing_) into _intents_ and _effects_ is the characteristic difference from existing approaches. Both stimuli are combined into a _messages_ for transporting and feeding them into the system. Each _message_ induces at most one _task_ for triggering side-effects. Combining _**in**tent_, _ef**fec**t_, and _**t**ask_ gives **infect**. ## License Licensed under the Mozilla Public License 2.0 (MPL-2.0) (see [MPL-2.0.txt](LICENSES/MPL-2.0.txt) or ).
