Using class based component

Setup store

import React from "react";
import { initStore } from "godam-react";
import { Godam, Mutation, Expression } from "godam";

class RootMutation extends Mutation {
    firstName(value) {
        this.state.firstName = value;
    }
    lastName(value) {
        this.state.lastName = value;
    }
}

class RootExpression extends Expression {

    get fullName() {
        return `${this.get('firstName')} ${this.get('lastName')}`
    }

    constructor() {
        super();
        this.markComputed(["firstName", 'lastName'], "fullName");
    }
}

const store = new Godam({
    state: {
        firstName: 'ujjwal',
        lastName: 'gupta'
    },
    mutations: RootMutation,
    expressions: RootExpression
})

initStore(store, React);

Using in component

import React from "react";
import { mapState, createState, mapExpression, mapMutation } from "godam-react";

export default class Layout extends React.Component {

        this.createState({

            fullName: mapExpression('fullName')
        });
        
        this.createMethod({

        })
    }

    }
