v-crud-state

A Vue mixin that allows you simply to manage CRUD state.

Installation

About state

This package recognizes 4 states from hash value of URL by default.

• index
• create
• edit
• show

It means that your URL should be https://example.com/test#index if you'd like to set state as index.

And state value is also available using :.

https://example.com/test#edit:15 https://example.com/test#show:value

Preparation

Set this.initState() in mounted().

new Vue({
    el: '#app',
    mounted:function() {

        this.initState();

    }
});

Usage

This package automatically calls onChangeState() when changing URL.
So add the method as follows.

new Vue({
    el: '#app',
    methods: {
        onChangeState: function(state, stateValue) {

            // Your code here

        }
    }
});

Note: state and stateValue are optional.

Retrieve current state

You can retrieve a current state through this.state.

if(this.state == 'create') {

    // create

}

Or you also have specific ways.

if(this.isIndex) {

    // Index

} else if(this.isCreate) {

    // Create

} else if(this.isEdit) {

    // Edit

} else if(this.isShow) {

    // Show

} else if(this.hasState) {

    // Has state

}

Retrieve state value

You can retrieve a current state value through this.stateValue.

const value = this.stateValue;

Note: Default value is null.

Default state

If a current state is not available, the state will change to the default one that you set in advance.

data: {
    defaultState: 'index' // optional
}

It means that a hash of the URL will automatically change to #index in this case.

Additional states

Your own states are available by setting additionalStates in data property.

data: {
    additionalStates: ['confirmation']
},

In this case, your URL should be https://example.com/test#confirmation.

Of course, you can retrieve state value as follows.
https://example.com/test#confirmation:value

Retrieve value corresponding a state

For example, you have titles object in data as follows.

data: {
    titles: {
        index: 'Title of INDEX',
        create: 'Title of CREATE',
        edit: 'Title of EDIT',
        show: 'Title of SHOW',
        confirmation: 'Title of confirmation' // In case that you set an additional state called "confirmation".
    }
}

In this case, you can automatically retrieve a title corresponding a current state through stateData().

const title = this.stateData('titles');    // depending on the states
