mobx-app-model

mobx-model (experiment)

A simple wrapper around mobx.

Status

It's an experiment. We are going to use it in our project and we are prepared to tweak it until it fits to our use cases.

I cannot recommend anyone to use it in real project because it is in an early stage.

If you like it or have ideas how to improve it I will be happy to hear them.

Instalation

npm install --save mobx-app-model

to use typescript you need also install following typings:

typings install --save --ambient es6-shim
typings install --save --ambient whatwg-fetch

Goals

• actions which are simple to test
• targets which are created from these action and can be used directly in react components without binding
• have composable models
• posible side effects (this needs to be improved)

Description

• state - initial state of your model, this creates the state property on the model (mobx observable)
• actions - methods where model and arguments are passed, they run in mobx transaction
• inputs - method that enables to create additional inputs that can be connected throug drivers rx subject, ... (see examples - gif-fetcher)
• init - enables to init model during creation, good for composing other models

Example

    import { modelFactory } from 'mobx-factory';
    import { autorun } from 'mobx';
 
    export const createModel = modelFactory({ 
        
        state: {
            value: 0
        },
        
        actions: {
            
            reset({state}) {            
                state.value = 0;
            },
            
            increment({state}) {
                state.value += 1;
            },
            
            decrement({state}) {
                state.value -= 1;
            },
            
            set({state}, value) {
                value = parseInt(value, 10);
                state.value = isNaN(value) ? null : value;
            }        
        }
    });
 
    const model = createModel();
 
    autorun(() => {
        console.log(model.state.value);
    });
    
    model.targets.increment(); // 1
    model.targets.increment(); // 2
