How to build a Keyword density tool using Vue.js and PHP

In this tutorial, we will make use of VueJS and PHP to build a really cool keyword density tool. On the Vue side, we’ll make use of components, templates, and root elements, and more. We will use PHP to generate the form we need, as well as to handle form processing, in addition to making use of the substr_count() function to provide the data we need. You might also like how to use vuejs in laravel as well. Let’s see how we can do this, it should be fun.

Declare The Vue Component

The first step that we will take is to declare a component for our application. In this instance, we are creating a keywordcounter component as shown by the first argument passed to the .component() method. We pass an object as the second parameter to this method. It has properties of template, props, data and methods. The template is a string which serves as the actual markup for the Vue component.

In this example, it begins with a hashtag, which means that Vue will treat this string as a querySelector for which that innerHTML will be used as the template string. Our props property is an object, which in this case contains to properties, data and columns. The values of these properties are arrays, and we will fill them dynamically a little later on. The data property holds a function, or rather references a function. There is a bit of magic happening here, as Vue actually turns any properties into getters and setters which is what gives the framework it’s reactive nature. Finally, we have the methods property, which is an object that contains methods to be used in the Vue instance. It is a means of keeping all of your functionality neat and tidy. Methods in the methods property have their this context set to the Vue instance.

<script>
	Vue.component('keywordcounter', {
		template: '#keywordcounter-template',
		props: {
			data: Array,
			columns: Array
		},
		data: function () {
			var sortOrders = {};
			this.columns.forEach(function (key) {
				sortOrders[key] = 1
			});
			return {
				sortKey: '',
				sortOrders: sortOrders
			}
		},
		methods: {
			sortBy: function (key) {
				this.sortKey = key;
				this.sortOrders[key] = this.sortOrders[key] * -1;
			}
		}
	});
</script>

Present a form to enter a haystack and keyword(s) to search

In this step we will use a simple combination of HTML and PHP to present a form for which we can collect some data. First off, we have a form element with the action set to substr_count.php and the method is post. What this means is that we will use the post http method to submit any data we collect to the PHP file named substr_count.php.

In our case, this is literally a single page application, so all snippets on this page can be assembled in order to create your own working example. Inside of the form tag, we have a textarea which will accept the data to be known as haystack, and a text input which will collect a comma separated list of keywords that we will analyze in the haystack data. Our inputs make use of the isset PHP function in order to repopulate the inputs on each successive testing of data. This way, you wouldn’t have to re enter all of the information into the form in order to search on say a different set of keywords. Finally we have just a simple button which allows us to submit the form.

<form action="substr_count.php" method="post">
    <label for="haystack">Enter text to analyze here.</label>
    <textarea name="haystack" id="haystack" class="form-control" rows="7"><?php if (isset($_POST['haystack'])) {
            echo $_POST['haystack'];
        } ?></textarea>
    <label for="keyword">Enter comma separated keywords to search for here.</label>
    <input name="keyword" id="keyword" type="text" class="form-control" value="<?php if (isset($_POST['keyword'])) {
        echo $_POST['keyword'];
    } ?>">
    <button type="submit">Submit</button>
</form>

Define the keywordcounter-template template

In the section above where we talked about the string template, and how it is used as a querySelector when prefixed with a hashtag. Below, we now find ourselves making use of <script type="x-template"> to define our template. This is how the component finds it’s template. This section here contains the markup and logic that will define the data we present to the user. In our case we have a simple table with some bootstrap styling.

You’ll notice that the th and tr tags hold some special markup. This is the markup of VueJS which is able to turn our plain HTML into markup capable of logic processing. In the th tag, we use v-for to loop over any available data, give it a nice style of a hand pointer, attach a click handler which fires the sortBy() method, apply an active class if the current table is active, capitalize the first letter, and determine if the sort is ascending or descending. In short, this markup allows us to click on the table header to sort by that column. When we run our little application, we will be able to sort by the Term, or by the Count of each term.

You’ll notice that the tr tag also makes use of Vue’s custom markup. What it is doing there is dynamically populating each row of the table with two td elements. One for the search Term, and one for the Number of times, or Count of how often that search term appeared in the haystack. Behind the scenes, we are actually making use of substr_count() to find this data for use, then we use Vue to display the results in a beautiful interactive table with sorting capabilities.

<script type="text/x-template" id="keywordcounter-template">
    <table class="table table-hover">
        <thead>
        <tr>
            <th v-for="key in columns"
                style="cursor:pointer;"
                @click="sortBy(key)"
                :class="{active: sortKey == key}">
                {{key | capitalize}}
          <span class="arrow"
                :class="sortOrders[key] > 0 ? 'asc' : 'dsc'">
          </span>
            </th>
        </tr>
        </thead>
        <tbody>
        <tr v-for="
        entry in data
        | orderBy sortKey sortOrders[sortKey]">
            <td v-for="key in columns">
                {{entry[key]}}
            </td>
        </tr>
        </tbody>
    </table>
</script>

Define the root element

This markup corresponds to the name we gave to the component we registered in the first step. Now we can reference it with these custom HTML tags like so.

<div id="findkeywords">
    <keywordcounter
        :data="keywordcounterData"
        :columns="keywordcounterColumns">
    </keywordcounter>
</div>

Fill the data that populates the component

In this step, we actually have to use PHP to generate portions of the script in our pages, since this is the data that will be dynamic based on the information that we fill out in the form and submit to the application. We actually have two cases here, if the data submitted results in several terms and counts, the first branch is taken. If only one term and count is found, we take the second branch.

<?php
if (isset($_POST['haystack']) and isset($_POST['keyword'])) {
    $haystack = $_POST['haystack'];
    $keyword = $_POST['keyword'];
 
    if (strstr($keyword, ',')) {
        $i = 1;
        $keywords = explode(',', $keyword);
        ?>
 
        <script>
            // fill the data that populates the component
            var action = new Vue({
                el: '#findkeywords',
                data: {
                    searchQuery: '',
                    keywordcounterColumns: ['term', 'count'],
                    keywordcounterData: [
                        <?php
                        foreach ($keywords as $keyword) {
                            echo ' { term: "' . $keyword . '", count: ' . substr_count($haystack, $keyword) . ' },';
                        }
                        ?>
                    ]
                }
            });
        </script>
 
    <?php
    } else {
    ?>
        <table class="table table-hover">
            <thead>
            <tr>
                <th style="cursor:hand;"> Term <span class="arrow asc"> </span></th>
                <th style="cursor:hand;" class="active"> Count <span class="arrow asc"> </span></th>
            </tr>
            </thead>
            <tbody>
            <tr>
                <td><?php echo $keyword ?></td>
                <td><?php echo substr_count($haystack, $keyword); ?></td>
            </tr>
            </tbody>
        </table>
        <?php
    }
}
?>

Testing out our application

Finally, we are ready to take our little application for a spin. Enter a bunch of text into the text area, and a collection of terms that are comma separated into the text input field, then click submit.

Sort By Term

After submitting the data to our application, we can click on the Term table header to sort our results via Term name.
sort by term

Sort By Count

After submitting the data to our application, we can click on the Count table header to sort our results via count.
sort by count

Did you know!

According to a web development survey 2020, JavaScript is the most used language for the 8th year, with 67.7% of people choosing it. With this came up several javascript frameworks for frontend, backend development, or even testing.

And one such framework is Vue.Js. It is used to build simple projects and can also be advanced to create sophisticated apps using state-of-the-art tools. Beyond that, some other solid reasons give Vuejs a thumbs up for responsive web application development.

Want to know them? Then follow this blog until the end. Through this article, I will describe all the reasons and benefits of Vue js development. So, stay tuned.

Vue.Js - A Brief Introduction

Released in the year 2014 for public use, Vue.Js is an open-source JavaScript framework used to create UIs and single-page applications. It has over 77.4 million likes on Github for creating intuitive web interfaces.

The recent version is Vue.js 2.6, and is the second most preferred framework according to Stack Overflow Developer Survey 2019.

Every Vue.js development company is widely using the framework across the world for responsive web application development. It is centered around the view layer, provides a lot of functionality for the view layer, and builds single-page web applications.

Some most astonishing stats about Vue.Js:

• Vue was ranked #2 in the Front End JavaScript Framework rankings in the State of JS 2019 survey by developers.

• Approximately 427k to 693k sites are built with Vue js, according to Wappalyzer and BuiltWith statistics of June 2020.

• According to the State of JS 2019 survey, 40.5% of JavaScript developers are currently using Vue, while 34.5% have shown keen interest in using it in the future.

• In Stack Overflow's Developer Survey 2020, Vue was ranked the 3rd most popular front-end JavaScript framework.

Why is Vue.Js so popular?

• High-speed run-time performance
• Vue.Js uses a virtual DOM.
• The main focus is on the core library, while the collaborating libraries handle other features such as global state management and routing.
• Vue.JS provides responsive visual components.

Top 7 Reasons to Choose Vue JS for Web Application Development

Vue js development has certain benefits, which will encourage you to use it in your projects. For example, Vue.js is similar to Angular and React in many aspects, and it continues to enjoy increasing popularity compared to other frameworks.

The framework is only 20 kilobytes in size, making it easy for you to download files instantly. Vue.js easily beats other frameworks when it comes to loading times and usage.

Take a look at the compelling advantages of using Vue.Js for web app development.

#1 Simple Integration

Vue.Js is popular because it allows you to integrate Vue.js into other frameworks such as React, enabling you to customize the project as per your needs and requirements.

It helps you build apps with Vue.js from scratch and introduce Vue.js elements into their existing apps. Due to its ease of integration, Vue.js is becoming a popular choice for web development as it can be used with various existing web applications.

You can feel free to include Vue.js CDN and start using it. Most third-party Vue components and libraries are additionally accessible and supported with the Vue.js CDN.

You don't need to set up node and npm to start using Vue.js. This implies that it helps develop new web applications, just like modifying previous applications.

The diversity of components allows you to create different types of web applications and replace existing frameworks. In addition, you can also choose to hire Vue js developers to use the technology to experiment with many other JavaScript applications.

#2 Easy to Understand

One of the main reasons for the growing popularity of Vue.Js is that the framework is straightforward to understand for individuals. This means that you can easily add Vue.Js to your web projects.

Also, Vue.Js has a well-defined architecture for storing your data with life-cycle and custom methods. Vue.Js also provides additional features such as watchers, directives, and computed properties, making it extremely easy to build modern apps and web applications with ease.

Another significant advantage of using the Vue.Js framework is that it makes it easy to build small and large-scale web applications in the shortest amount of time.

#3 Well-defined Ecosystem

The VueJS ecosystem is vibrant and well-defined, allowing Vue.Js development company to switch users to VueJS over other frameworks for web app development.

Without spending hours, you can easily find solutions to your problems. Furthermore, VueJs lets you choose only the building blocks you need.

Although the main focus of Vue is the view layer, with the help of Vue Router, Vue Test Utils, Vuex, and Vue CLI, you can find solutions and recommendations for frequently occurring problems.

The problems fall into these categories, and hence it becomes easy for programmers to get started with coding right away and not waste time figuring out how to use these tools.

The Vue ecosystem is easy to customize and scales between a library and a framework. Compared to other frameworks, its development speed is excellent, and it can also integrate different projects. This is the reason why most website development companies also prefer the Vue.Js ecosystem over others.

#4 Flexibility

Another benefit of going with Vue.Js for web app development needs is flexibility. Vue.Js provides an excellent level of flexibility. And makes it easier for web app development companies to write their templates in HTML, JavaScript, or pure JavaScript using virtual nodes.

Another significant benefit of using Vue.Js is that it makes it easier for developers to work with tools like templating engines, CSS preprocessors, and type checking tools like TypeScript.

#5 Two-Way Communication

Vue.Js is an excellent option for you because it encourages two-way communication. This has become possible with the MVVM architecture to handle HTML blocks. In this way, Vue.Js is very similar to Angular.Js, making it easier to handle HTML blocks as well.

With Vue.Js, two-way data binding is straightforward. This means that any changes made by the developer to the UI are passed to the data, and the changes made to the data are reflected in the UI.

This is also one reason why Vue.Js is also known as reactive because it can react to changes made to the data. This sets it apart from other libraries such as React.Js, which are designed to support only one-way communication.

#6 Detailed Documentation

One essential thing is well-defined documentation that helps you understand the required mechanism and build your application with ease. It shows all the options offered by the framework and related best practice examples.

Vue has excellent docs, and its API references are one of the best in the industry. They are well written, clear, and accessible in dealing with everything you need to know to build a Vue application.

Besides, the documentation at Vue.js is constantly improved and updated. It also includes a simple introductory guide and an excellent overview of the API. Perhaps, this is one of the most detailed documentation available for this type of language.

#7 Large Community Support

Support for the platform is impressive. In 2018, support continued to impress as every question was answered diligently. Over 6,200 problems were solved with an average resolution time of just six hours.

To support the community, there are frequent release cycles of updated information. Furthermore, the community continues to grow and develop with backend support from developers.



Wrapping Up

VueJS is an incredible choice for responsive web app development. Since it is lightweight and user-friendly, it builds a fast and integrated web application. The capabilities and potential of VueJS for web app development are extensive.

While Vuejs is simple to get started with, using it to build scalable web apps requires professionalism. Hence, you can approach a top Vue js development company in India to develop high-performing web apps.

Equipped with all the above features, it doesn't matter whether you want to build a small concept app or a full-fledged web app; Vue.Js is the most performant you can rely on.

How to build a Keyword density tool using Vue.js and PHP

In this tutorial, we will make use of VueJS and PHP to build a really cool keyword density tool. On the Vue side, we’ll make use of components, templates, and root elements, and more. We will use PHP to generate the form we need, as well as to handle form processing, in addition to making use of the substr_count() function to provide the data we need. You might also like how to use vuejs in laravel as well. Let’s see how we can do this, it should be fun.

The data property holds a function, or rather references a function. There is a bit of magic happening here, as Vue actually turns any properties into getters and setters which is what gives the framework it’s reactive nature. Finally, we have the methods property, which is an object that contains methods to be used in the Vue instance. It is a means of keeping all of your functionality neat and tidy.

			sortBy: function (key) {
				this.sortKey = key;
				this.sortOrders[key] = this.sortOrders[key] * -1;
			}
		}
	});
</script>

Present a form to enter a haystack and keyword(s) to search

    <textarea name="haystack" id="haystack" class="form-control" rows="7"><?php if (isset($_POST['haystack'])) {
            echo $_POST['haystack'];
        } ?></textarea>
    <label for="keyword">Enter comma separated keywords to search for here.</label>
    <input name="keyword" id="keyword" type="text" class="form-control" value="<?php if (isset($_POST['keyword'])) {

<script type="text/x-template" id="keywordcounter-template">

        <thead>
        <tr>
            <th v-for="key in columns"
                style="cursor:pointer;"
                @click="sortBy(key)"

            </td>
        </tr>
        </tbody>
    </table>
</script>

Define the root element

This markup corresponds to the name we gave to the component we registered in the first step. Now we can reference it with these custom HTML tags like so.

<div id="findkeywords">
    <keywordcounter
        :data="keywordcounterData"
        :columns="keywordcounterColumns">
    </keywordcounter>
</div>

Fill the data that populates the component

In this step, we actually have to use PHP to generate portions of the script in our pages, since this is the data that will be dynamic based on the information that we fill out in the form and submit to the application. We actually have two cases here, if the data submitted results in several terms and counts, the first branch is taken. If only one term and count is found, we take the second branch.

<?php
if (isset($_POST['haystack']) and isset($_POST['keyword'])) {
    $haystack = $_POST['haystack'];
    $keyword = $_POST['keyword'];
 
    if (strstr($keyword, ',')) {
        $i = 1;
        $keywords = explode(',', $keyword);
        ?>
 
        <script>
            // fill the data that populates the component
            var action = new Vue({
                el: '#findkeywords',
                data: {
                    searchQuery: '',
                    keywordcounterColumns: ['term', 'count'],
                    keywordcounterData: [
                        <?php
                        foreach ($keywords as $keyword) {
                            echo ' { term: "' . $keyword . '", count: ' . substr_count($haystack, $keyword) . ' },';
                        }
                        ?>
                    ]
                }
            });
        </script>
 
    <?php
    } else {
    ?>
        <table class="table table-hover">
            <thead>
            <tr>
                <th style="cursor:hand;"> Term <span class="arrow asc"> </span></th>
                <th style="cursor:hand;" class="active"> Count <span class="arrow asc"> </span></th>
            </tr>
            </thead>
            <tbody>
            <tr>
                <td><?php echo $keyword ?></td>
                <td><?php echo substr_count($haystack, $keyword); ?></td>
            </tr>
            </tbody>
        </table>
        <?php
    }
}
?>

Testing out our application

Finally, we are ready to take our little application for a spin. Enter a bunch of text into the text area, and a collection of terms that are comma separated into the text input field, then click submit.

Sort By Term

After submitting the data to our application, we can click on the Term table header to sort our results via Term name.
sort by term

Sort By Count

After submitting the data to our application, we can click on the Count table header to sort our results via count.
sort by count
