This plugin is a little bit based on Wruczek/Bootstrap-Cookie-Alert.

First, you will need to install NPM. Then, run the following command:

$ npm install bs-cookie-notice --save

Here is a basic example of using the plugin:

<script type="text/javascript">
    var notice = new BsCookieNotice();
</script>

Automatically opens the notice in the browser when loading the page.

The default color is dark, but you can choose between it and light. Example:

new BsCookieNotice({
    color: 'light'
});

You can change the default texts language, just by setting the locale property (English, Portuguese and Spanish). Example:

new BsCookieNotice({
    locale: 'pt'
});

The default language of the plugin is English.

If you want to change the text to a custom one, you can pass an object with properties named message, accept and / or more to the customMessage property. Example:

new BsCookieNotice({
    locale: 'pt',
    customMessage: {
        more: "Quero saber mais...",
        accept: "Aceitar Todos"
    }
});

Note that it's not necessary to pass all properties on the object, you can choose a default language and just change the text of the Accept button for example.

One of the indispensable things that needs to be configured is the "Learn more" link URL. For this you can pass to the more property an object containing an option named href with the URL value you want. Example:

new BsCookieNotice({
    more: {
        href: "https://github.com/parkejunior",
    }
});

There may also be a need to use the target attribute. To do this, you can pass the attribute value ( _blank, _self, etc.) to the target property in the more object. Example:

new BsCookieNotice({
    more: {
        href: "https://github.com/parkejunior",
        target: "_blank",
    }
});

In the same way that it's possible to configure the URL of the "Learn More" link, it's also possible to configure the "Accept" button.

You can add custom classes for these elements by passing an object to the more (for "Learn More") and accept (for the "Accept" button) properties. For example, changing the color of the button using the Bootstrap class:

new BsCookieNotice({
    accept: {
        class: ["btn-danger"],
    }
});

Or add a custom color for the link:

new BsCookieNotice({
    more: {
        href: "https://github.com/parkejunior",
        class: ["text-warning", "another-classes"],
    }
});

It's also possible to add callbacks to the "Accept" button and the "Learn More" link. Example:

new BsCookieNotice({
    accept: {
        callback: function () {
            console.log("User accept cookies");
        }
    },
    more: {
        href: "https://github.com/parkejunior",
        callback: function () {
            console.log("User wants to learn more");
        }
    }
});

Note: You cannot override the default "Accept" button event, just add a callback.

The default notice hide expiration time is 365 days after acceptance. You can change this by passing the number of days to the expire property. Example:

new BsCookieNotice({
    expire: 30
});

In this example, after 30 days after the user accepts the cookies, the message will be displayed again and the user must accept it again.

You can test the plugin by opening the index.html file in your browser.

If you find any incorrect English grammar or any suggestions on how to improve the plugin, I appreciate it.
