Environment Variables

Using environment variables may be sometimes necessary even for frontend.

On install, an env.js file is created in the root directory and the config/prod.env.js file is changed to ensure the variables are processed.

Packages

• axios
• hello.js
• sweetalert
• vue-social-sharing
• vue-toasted

Events

• requestOK ( requestResponse, pageNumber ): Emitted when the request is successful.
• requestError ( requestResponse ): Emitted when the request fails.

Global Properties

Two properties are added to all Vue instances, thereby making them available in all components on the context this.

this.$event

A global event bus.

this.$hello

The hellojs object.

this.$http

A wrapper around axios. It operates exactly like axios and has all the instance methods.

Callbacks

All instance methods of $http return a Promise. Both the resolve and the reject callback functions have the same parameters:

this.$http.get('/path/to/resource')
    .then((data, status, headers, originalAxiosResponseObject) => {})
    .catch((data, status, headers, originalAxiosResponseObject) => {});

Note: data is the actual response received from the server.

this.$toasted

The vue-toasted object.

Methods

Some utility functions are also provided and are available on the this context:

this.deepDelete(target, baseObject)

Safely deletes a deep key on an object (including arrays).

let obj = {
    first_name: 'John',
    last_name: 'Doe',
    books: [
        {
            id: 1,
            title: 'The Tale of the Lost Man',
            year: 2008
        },
        {
            id: 2,
            title: 'Another Year Gone',
            year: 2009
        }
    ],
    contacts: {
        phone: '012345678',
        email: '[email protected]',
        facebook: 'johndoe',
        twitter: '@johndoe'
    }
};

// array
this.deepDelete('books.0.year', obj);
this.deepDelete('books.1', obj);
// object
this.deepDelete('contacts.phone', obj);

this.deepValue(target, baseObject, defaultValue)

Safely retrieves the value of a deep property on the baseObject. If the value is undefined, the defaultValue is returned.

Using the obj example above,

this.deepValue('books.1.year', obj); // 20009
this.deepValue('books.2.year', obj); // undefined
this.deepValue('books.2.year', obj, 'Not available'); // Not availalbe

this.deepValue('contacts.twitter', obj); // @johndoe
this.deepValue('contacts.linkedin', obj, 'N/A'); // N/A

this.env(key, defaultValue)

Get an environment variable

this.env('NODE_ENV'); // development
this.env('node_env'); // development

this.env('not_defined_variable', 'Not set'); // Not set

this.findIn(data, func, defaultValue)

A unified function to search an object (including arrays) and retrieve the first match. If no match is found, the defaultValue is returned.

var objects = {
    first: {
        id: 1,
        time: 10,
    },
    second: {
        id: 2,
        time: 3
    }
};
this.findIn(objects, item => item.time === 3); // {id: 2, time: 3}
this.findIn(objects, item => item.time === 6, {}); // {}

// The same thing applies for arrays

this.pull(key, obj)

Removes the given key and its value from the given object. If the object is reactive, the object is notified of the pull. Parameter key may be dot-denoted.

this.pullValue(value, obj)

Searches for the value in the object and removes it and its key from the given object. If the object is reactive, the object is notified of the pull.

push(value, obj, key, ignoreDots = false)

Pushes a value to the given object (or array). If an object, the key parameter MUST be provided.

Parameter key may be dot-denoted. However, is parameter ignoreDots is true, then the whole key, w/ the dots, is used as a whole key.

this.push([], this.data, 'contacts.lists'); // { contacts: { lists: [] } }
this.push([], this.data, 'contacts.lists', true); // { "contacts.lists" : [] }

this.range(start, end, step)

VueJS' v-for can be used for number ranges however, they are not zero-indexed. This is an implementation that is zero-indexed.

<!-- Creates 11 divs with contents 0 to 10  -->
<div v-for="num in range(10)">{{ num }}</div>

<!-- Creates 10 divs with contents 1 to 10  -->
<div v-for="num in range(1, 10)">{{ num }}</div>

<!-- Creates 10 divs with contents 5 to 50 in steps of 5  -->
<div v-for="num in range(5, 50, 5)">{{ num }}</div>

<!-- Creates 10 divs with contents 10 to 1  -->
<div v-for="num in range(10, 1)">{{ num }}</div>

<!-- Creates 6 divs with contents 10 to 0, in steps of -2  -->
<div v-for="num in range(10, 0, 2)">{{ num }}</div>

this.set(key, value, obj)

Adds a value to an object at the given key while ensuring reactivity.

this.store(key, value)

Interacts with the Vuex store object.

let store = this.store(); // Fetches the store object
store.set('env', 'testing'); // Store object
store.get('env'); // testing
store.remove('env'); // testing
store.get('env'); // undefined

// shortcuts

this.store('env', 'testing'); // Store object
this.store('env'); // testing

this.swal( ... )

The sweetalert function

this.toast(messae, options)

A shortcut to this.$toasted.show(message, options).
