Learning and creating local storage apps in JavaScript before delving into databases offers several important benefits and insights that lay a solid foundation for understanding databases and more complex data management systems. Here's why it's crucial to start with local storage apps:

Fundamental Concepts

Local storage apps introduce you to core concepts of data storage, retrieval, and manipulation in a simplified environment. This includes understanding data structures, managing data lifecycles, and interacting with data through code. 

Synchronous Operations

Local storage operations are synchronous, meaning they happen in a predictable sequence. This helps you understand the flow of data operations and how they impact the user experience.

Isolation from Network and Server Complexity

By working with local storage, you can concentrate solely on client-side code and data manipulation. This isolates you from the complexities of network communication, server setup, and database configuration, which can be overwhelming for beginners. 

Data Modeling

Creating local storage apps requires you to think about data modeling – deciding what data to store, how to structure it, and how to retrieve it efficiently. This skill is directly transferable to designing database schemas later on. 

Error Handling and Debugging

You'll encounter errors and bugs while working with local storage. Learning how to debug and handle these issues is a valuable skill that directly applies to working with databases. 

Applicable Principles

Many principles you learn while working with local storage, such as data validation, security considerations, and handling different data types, directly carry over to database management.

In today's fast-paced world, effective task management is crucial for maintaining productivity and organization. Whether you're managing a small project or tracking customer support requests, having a system to keep track of tickets can greatly simplify your workflow. In this article, we'll guide you through the process of creating a simple ticket tracker using HTML, Bootstrap, and JavaScript.

With that said, let’s get started!

Requirements

Before we begin, make sure you have a basic understanding of HTML, Bootstrap, and JavaScript. We'll also be using Bootstrap to style our application, so having some familiarity with it would be beneficial.

Setting Up the Project

HTML Structure: Start by creating a new folder for your project and inside it, create an index.html file. Set up the basic HTML structure and include necessary libraries:

We’ll start by creating the HTML markup structure containing the DOM content of the ticket tracker. To keep things simple, we will need just a few HTML elements:

Link tag for css bootstrap integration for styling ,
A body onload tag to enable ticket issues to remain in DOM after each page reload
A section for ticket form data input divs

the following code below outlines the first two points;

At the bottom of the code, you link the javascript , bootstrap styling , and chanceJS for ticket ID Issuance.

<!DOCTYPE html>

<body onload="fetchIssues()">  <!--This will be populated by JS-->

    <script src="http://chancejs.com/chance.min.js"></script>
</body>
</html>

Note : You can also use vanilla CSS to style your layouts, we are using bootstrap to ease time constraints in styling out.

Creating the Ticket Tracker Interface

Form for Ticket Entry: Within the of your index.html file, create a form to input new tickets:

<section class="container">   
        <h1>Ticktrak</h1>
        <section class="jumbotron">
            <h3>Add New Tracking Issue:</h3>
            <form id="issueInputForm">
                <div class="form-group">
                    <label for="issueSubjInput">Subject</label>
                    <input type="text" class="form-control" id="issueSubjInput" placeholder="Issue Subject...">
                </div>
                <div class="form-group">
                    <label for="issueDescInput">Description</label>
                    <input type="text" class="form-control" id="issueDescInput" placeholder="Issue Description...">
                </div>
                <div class="form-group">
                    <label for="issueSeverityInput">Severity</label>
                    <select class="form-control" id="issueSeverityInput">
                        <option value="Low">Low</option>
                        <option value="Medium">Medium</option>
                        <option value="High" selected>High</option>
                    </select>
                </div>
                <div class="form-group">
                    <label for="issueAssignedToInput">Assigned To</label>
                    <input type="text" class="form-control" id="issueAssignedToInput" placeholder="Enter Person Responsible...">
                </div>
                <button type="submit" class="btn btn-warning">Add</button> 
            </form>
        </section>
        <section class="row">
            <div class="col-lg-12">
                <div id="issuesList">


       <!-- empty div to be occupied  by JS when event listener is triggered—>


                </div>
            </div>

Implementing JavaScript Logic:

Our ticket tracker isn’t working right now because we have yet to add some interactivity using JavaScript, which is exactly what we are going to do next.

We will have to add some event listeners to the input button for form submission and also storage of form data in local storage, and also automating listing of open issues in the DOM whenever they are clicked on.

To achieve this, we will tackle the JavaScript code needed to get our form input working section by section so that it’s easy to understand and follow along.

JavaScript for Ticket Handling: Create a main.js file in your project folder. This is where we'll handle the ticket creation and display logic.
Then we will write a function called fetchIssues() to facilitate display of stored form in local storage in the DOM. Under it, We create two variables respectively;
- The first variable issues; for grabbing data stored as an Object stored in local storage, then parse it from a string into DOM data
  - The Second Variable issuesList; for grabbing data from issues variable and display in the empty html div in the DOM
We log the console for emergency debugging and confirming the parsed data contents that was displayed;

function fetchIssues() {  
    let issues = JSON.parse(localStorage.getItem('issues'))
    let issuesList = document.getElementById('issuesList')
    console.log(issues)

}

We then add a method under the variables for enabling displaying the data in html format

function fetchIssues() {  
    let issues = JSON.parse(localStorage.getItem('issues'))
    let issuesList = document.getElementById('issuesList')
    console.log(issues)

issuesList.innerHTML = '';

}

We will run a for loop to get all available input data in each ticket stored as objects in local storage

function fetchIssues() {  
    let issues = JSON.parse(localStorage.getItem('issues'))
    let issuesList = document.getElementById('issuesList')
    console.log(issues)

issuesList.innerHTML = '';

for (let i = 0; i < issues.length; i++) { // run loop to get all available data in each ticket stored as objects in local storage
     let id = issues[i].id
        let subject = issues[i].subject
        let description = issues[i].description
        let severity = issues[i].severity
        let assignedTo = issues[i].assignedTo
        let status = issues[i].status
        let statusColor = status == "Closed" ? 'label-success' : 'label-info'

    }  


}

We then style how our (now empty) form data of issues in html will appear in the DOM

function fetchIssues() {  
         let issues = JSON.parse(localStorage.getItem('issues'))
         let issuesList = document.getElementById('issuesList')
         console.log(issues)

         issuesList.innerHTML = '';

        for (let i = 0; i < issues.length; i++) {  // run loop to get all available data in each ticket stored as objects in local storage
        let id = issues[i].id
        let subject = issues[i].subject
        let description = issues[i].description
        let severity = issues[i].severity
        let assignedTo = issues[i].assignedTo
        let status = issues[i].status
        let statusColor = status == "Closed" ? 'label-success' : 'label-info'

        issuesList.innerHTML +=  //style your empty form data of issues in html 
        '<div class="well">' +
        '<h6>Issue ID:' + id + '</h6>' +
        '<p><span class= "label ' + statusColor + ' ">' + status + '</span></p>' +
        '<h3>' + subject + '</h3>' +
        '<p>' + description + '</p>' + 
        '<p><span class="glyphicon glyphicon-time"></span> ' + severity + ' ' + '<span class="glyphicon glyphicon-user"></span>' + assignedTo + '</p>' +
        '<a href="#" class="btn btn-warning" onclick="setStatusClosed(\''+id+'\')">Close</a> ' + //pass ticket id to be changed to closed from id through onclick function in button
        '<a href="#" class="btn btn-danger" onclick="deleteIssue(\''+id+'\')">Delete</a> ' //pass ticket id to be deleted through onclick function in button
        + '</div>'
    }  


}

We then write another function saveIssues to be triggered by event listener to capture all data from the form of issues and save to local storage’

The first variable issueID contains a function method chance.guid() which is an open source random ID number generator to assign form id with form data to variables to be stored in an object which is then to be stored in local storage

Then we create an object storing form data value with key-value pair of the variables created above the object

function saveIssue(e) {
              let issueId = chance.guid()
              let issueSubject = document.getElementById('issueSubjInput').value
              let issueDesc = document.getElementById('issueDescInput').value
              let issueSeverity = document.getElementById('issueSeverityInput').value
              let issueAssignedTo = document.getElementById('issueAssignedToInput').value
             let issueStatus = 'Open'

             let issue = {   // object storing form data value
                  id: issueId,
                  subject: issueSubject,
                 description: issueDesc,
                 severity: issueSeverity,
                 assignedTo: issueAssignedTo,
                 status: issueStatus
           }

        }

then we have to create our good old conditional statements to first create an empty array to contain the newly created object, then pushing new input data to empty array, then set the value identified by key to value pair, convert array elements to string & save the data in local storage.

OR if data already exists grab the existing issues, parse them & push them to an array, convert back to string & store in local storage

function saveIssue(e) { // function to be triggered by event listener to capture all data from the form of issues and save to local storage
    let issueId = chance.guid()   //assign form id with form data to variables to be stored in an object which is then to be stored in local storage
    let issueSubject = document.getElementById('issueSubjInput').value
    let issueDesc = document.getElementById('issueDescInput').value
    let issueSeverity = document.getElementById('issueSeverityInput').value
    let issueAssignedTo = document.getElementById('issueAssignedToInput').value
    let issueStatus = 'Open'

    let issue = {   // object storing form data value
        id: issueId,
        subject: issueSubject,
        description: issueDesc,
        severity: issueSeverity,
        assignedTo: issueAssignedTo,
        status: issueStatus
    }

    if(localStorage.getItem('issues')===null) { //if there is no data served up from local storage when user opens for first time 
        let issues = []// set up an array in this case
        issues.push(issue) //push new data to empty array
        localStorage.setItem('issues', JSON.stringify(issues)) // set the value identified by key to value pair, convert array elements to string & save the data
    } else {
        let issues = JSON.parse(localStorage.getItem('issues')) //if it exists grab existing issues, parse them  & convert to array
        issues.push(issue) //push to array
        localStorage.setItem('issues', JSON.stringify(issues)) //convert back to string & store in local storage
    }

}

Under the Conditionals add a document read method to reset form after data is inputed, the adding to local storage to be saved

function saveIssue(e) { // function to be triggered by event listener to capture all data from the form of issues and save to local storage
    let issueId = chance.guid()   //assign form id with form data to variables to be stored in an object which is then to be stored in local storage
    let issueSubject = document.getElementById('issueSubjInput').value
    let issueDesc = document.getElementById('issueDescInput').value
    let issueSeverity = document.getElementById('issueSeverityInput').value
    let issueAssignedTo = document.getElementById('issueAssignedToInput').value
    let issueStatus = 'Open'

    let issue = {   // object storing form data value
        id: issueId,
        subject: issueSubject,
        description: issueDesc,
        severity: issueSeverity,
        assignedTo: issueAssignedTo,
        status: issueStatus
    }

    if(localStorage.getItem('issues')===null) { //if there is no data served up from local storage when user opens for first time 
        let issues = []// set up an array in this case
        issues.push(issue) //push new data to empty array
        localStorage.setItem('issues', JSON.stringify(issues)) // set the value identified by key to value pair, convert array elements to string & save the data
    } else {
        let issues = JSON.parse(localStorage.getItem('issues')) //if it exists grab existing issues, parse them  & convert to array
        issues.push(issue) //push to array
        localStorage.setItem('issues', JSON.stringify(issues)) //convert back to string & store in local storage
    }

    document.getElementById('issueInputForm').reset(); //reset form after input data & adding to local storage to be saved

    fetchIssues() //display, style new form issues

    e.preventDefault() //for the event listener to trigger the saveIssues function only and nothing else
}

We will then write another function setStatusClosed to grab outform issue , display issue in html in the DOM, then change status & resave in local storage, we will loop through the issues ,then we write a conditional to flip the status if issue id matches id to be passed in, then we “stringify” the issue to convert issue with flipped status back to string & store in local storage

function saveIssue(e) { // function to be triggered by event listener to capture all data from the form of issues and save to local storage
    let issueId = chance.guid()   //assign form id with form data to variables to be stored in an object which is then to be stored in local storage
    let issueSubject = document.getElementById('issueSubjInput').value
    let issueDesc = document.getElementById('issueDescInput').value
    let issueSeverity = document.getElementById('issueSeverityInput').value
    let issueAssignedTo = document.getElementById('issueAssignedToInput').value
    let issueStatus = 'Open'

    let issue = {   // object storing form data value
        id: issueId,
        subject: issueSubject,
        description: issueDesc,
        severity: issueSeverity,
        assignedTo: issueAssignedTo,
        status: issueStatus
    }

    if(localStorage.getItem('issues')===null) { //if there is no data served up from local storage when user opens for first time 
        let issues = []// set up an array in this case
        issues.push(issue) //push new data to empty array
        localStorage.setItem('issues', JSON.stringify(issues)) // set the value identified by key to value pair, convert array elements to string & save the data
    } else {
        let issues = JSON.parse(localStorage.getItem('issues')) //if it exists grab existing issues, parse them  & convert to array
        issues.push(issue) //push to array
        localStorage.setItem('issues', JSON.stringify(issues)) //convert back to string & store in local storage
    }

    document.getElementById('issueInputForm').reset(); //reset form after input data & adding to local storage to be saved

    fetchIssues() //display, style new form issues

    e.preventDefault() //for the event listener to trigger the saveIssues function only and nothing else

function setStatusClosed(id) { //to grab out issue , display issue, change status & resave in local storage
    let issues = JSON.parse(localStorage.getItem('issues')) 
    for(let i=0; i < issues.length; i++) { //loop through issues
        if(issues[i].id === id) { //if issue id matches id to be passed in, grab it out to dom, flip status 
            issues[i].status = "Closed"
        }
    }

    localStorage.setItem('issues', JSON.stringify(issues)) //convert issue with flipped status back to string & store in local storage, 

    fetchIssues()
}

}

We then write a function deleteIssue to pull issue out, attend to the form issue, get the data we want, delete & save back in local storage

 function saveIssue(e) { // function to be triggered by event listener to capture all data from the form of issues and save to local storage
    let issueId = chance.guid()   //assign form id with form data to variables to be stored in an object which is then to be stored in local storage
    let issueSubject = document.getElementById('issueSubjInput').value
    let issueDesc = document.getElementById('issueDescInput').value
    let issueSeverity = document.getElementById('issueSeverityInput').value
    let issueAssignedTo = document.getElementById('issueAssignedToInput').value
    let issueStatus = 'Open'

    let issue = {   // object storing form data value
        id: issueId,
        subject: issueSubject,
        description: issueDesc,
        severity: issueSeverity,
        assignedTo: issueAssignedTo,
        status: issueStatus
    }

    if(localStorage.getItem('issues')===null) { //if there is no data served up from local storage when user opens for first time 
        let issues = []// set up an array in this case
        issues.push(issue) //push new data to empty array
        localStorage.setItem('issues', JSON.stringify(issues)) // set the value identified by key to value pair, convert array elements to string & save the data
    } else {
        let issues = JSON.parse(localStorage.getItem('issues')) //if it exists grab existing issues, parse them  & convert to array
        issues.push(issue) //push to array
        localStorage.setItem('issues', JSON.stringify(issues)) //convert back to string & store in local storage
    }

    document.getElementById('issueInputForm').reset(); //reset form after input data & adding to local storage to be saved

    fetchIssues() //display, style new form issues

    e.preventDefault() //for the event listener to trigger the saveIssues function only and nothing else

function setStatusClosed(id) { //to grab out issue , display issue, change status & resave in local storage
    let issues = JSON.parse(localStorage.getItem('issues')) 
    for(let i=0; i < issues.length; i++) { //loop through issues
        if(issues[i].id === id) { //if issue id matches id to be passed in, grab it out to dom, flip status 
            issues[i].status = "Closed"
        }
    }

    localStorage.setItem('issues', JSON.stringify(issues)) //convert issue with flipped status back to string & store in local storage, 

    fetchIssues()
} 

    function deleteIssue (id) { //pull issue out cut out what we want to delete & save back
    let issues = JSON.parse(localStorage.getItem('issues'))
    for(let i=0; i < issues.length; i++) {
        if(issues[i].id === id) {
            issues.splice(i,1) //splicing at current indexin the array , cutting it in half, extract element & rejoin
        }
    }

    localStorage.setItem('issues', JSON.stringify(issues))

    fetchIssues()


}

Introduction

In today's fast-paced digital landscape, website and web application performance play a critical role in user experience. Slow-loading pages can lead to frustration, increased bounce rates, and diminished conversion rates. To address this challenge, developers and engineers continuously seek efficient frameworks that can optimize page load times and enhance overall performance. One such framework that has gained attention for its ability to improve page load speed is Remix.js. while most other Javascript frontend frameworks are also great frameworks for building client-side rendered web applications, Remix offers a faster page load and smaller codebase by focusing on server-rendered applications. This makes Remix a better choice for applications where performance is critical, such as e-commerce sites and other high-traffic websites. However, it is important to note that the choice of framework ultimately depends on the specific requirements of your project, so it is always a good idea to evaluate multiple options before making a decision.

This article explores how Remix.js excels in facilitating faster page loads compared to other frameworks, highlighting its key features and benefits.

i. Understanding the Importance of Page Load Speed

A. A Quick look at the concept of page load

Page load time is the amount of time it takes for a web page to fully load. Measured in seconds, it’s one of the indicators of a web page’s performance, and a slow one can hurt user engagement and, consequently, business performance.

How Is Page Load Time Calculated?

Page load time is calculated from the moment you click on a link or type in a website’s address to the moment when all the elements of the page are displayed on the screen. To make this request happen, the browser and the server go through the following cycle:

The user sends a server request. This can be clicking on a URL or a link to load a new page, or get a page with a list of products from a simple “table calendar” search from an e-commerce website.
The server processes the browser’s request.
The browser receives data/information from the server for the requested page. (Note: The time between sending a request to a server and receiving the first byte of data is called the time to first-byte (TTFB). Google uses this metric to measure how fast a website loads.)
The page’s content is processed, loaded, and displayed by the browser, and the requested page is fully loaded.

Several factors are taken into consideration when measuring the web page load time. Website owners can affect some of these, while others such as the user’s location, device, browser and internet connection are beyond their control, yet still affect the page load time. For example, the same web page can load differently on different browsers (e.g., Firefox, Chrome) and devices (e.g., desktop vs. tablet vs. mobile), and in different locations.

Why Is Page Load Time Important?

Your business bottom line is significantly influenced by your website’s page load time, as consumers desire speedy, easy-to-navigate websites. Here’s how:

SEO and Search Engine Ranking: Google uses web page loading time as a direct ranking factor, influencing a page’s position in the search results. A slow loading page can hurt your site’s SEO by increasing the bounce rate and decreasing the average session time, or by dropping the organic traffic from the search engines.
User engagement and customer satisfaction: Slow page load times also affect how users see and interact with your website. Over 70% Of Customers say that page speed impacts their likelihood to purchase. Consequently, close to half of them are less likely to buy and return to the slow website in the future.
Bounce Rate: If your page speed is poor, customers may not wait for it to load and leave instead to search for a faster website. According to Google Research the probability of a user leaving a website (bounce rate) increased by 32% when it took 1-3 seconds to load a page, by 90% when it took 1-5 seconds, and by 123% when it took more than 10 seconds to load a page.
Business aspects: Keeping page load times low is vital to enhance conversion rates and sales revenue. Every second lost is an opportunity lost. Studies show that 40% of users leave a website that takes longer than 3 seconds to load. Furthermore, for every additional second a website takes to load, a 7% drop in conversion rates may be expected.

B. A Comparison Metric For Page load speed efficiency

When comparing the efficiency of page load speed across different websites or web applications, several metrics can be used to assess and quantify performance. One commonly used metric is the Page Load Time (PLT), which measures the time it takes for a webpage to load completely. PLT provides a straightforward comparison of how quickly different pages load and is often the most important metric for user experience. However, there are other complementary metrics that can provide a more comprehensive evaluation of page load speed efficiency. Here are a few key metrics to consider:

First Contentful Paint (FCP): FCP measures the time it takes for the first piece of content to be rendered on the screen. It indicates how quickly users can see the page's primary content. FCP is particularly useful for evaluating perceived performance and providing a faster visual feedback to users. 
Time to Interactive (TTI): TTI measures the time it takes for a page to become fully interactive. It considers the time needed for all scripts, stylesheets, and other resources to load and execute, allowing users to interact with the page seamlessly. TTI is crucial for assessing the usability of interactive elements and ensuring a responsive user experience. 
Document Object Model (DOM) Content Loaded: DOM Content Loaded measures the time it takes for the HTML document to be fully parsed and the DOM tree to be constructed. It represents the point at which JavaScript can start interacting with the page's content. DOM Content Loaded is particularly relevant when evaluating the performance impact of JavaScript execution. 
Time to First Byte (TTFB): TTFB measures the time it takes for the first byte of data to be received from the server. It represents the server's responsiveness and network latency. A lower TTFB indicates a faster initial response and can contribute to improved overall page load speed.  
Resource Size and Number of Requests: In addition to time-based metrics, it's essential to consider the size of resources (e.g., HTML, CSS, JavaScript, images) and the number of requests made to retrieve those resources. Minimizing file sizes and reducing the number of server requests can significantly improve page load efficiency.

Why Those Green Squares In Your Github Do Not Necessarily Matter When It Comes To Getting A Job.

ebuka anthony — Sat, 04 Mar 2023 08:22:36 +0000

GitHub is a popular platform that hosts millions of repositories for open-source projects and other code-related resources. Many programmers use it to collaborate on projects, showcase their skills, and even land a job. One feature that attracts a lot of attention on GitHub is the commit streak, which represents the number of consecutive days a user has made at least one commit. While a high commit streak can be impressive, it doesn't necessarily indicate a programmer's skills or their ability to get a job.

Here are some reasons why your GitHub commit streak doesn't matter in getting a job:

Quantity doesn't always equal quality
Making a lot of commits in a short period of time might seem impressive, but it doesn't necessarily mean that the code is high-quality or useful. A high commit streak can be achieved by making small, insignificant changes, such as fixing typos or adding comments. What really matters to employers is the quality of your code and your ability to solve problems effectively.
Other factors matter more
Employers care about a variety of factors when hiring programmers, such as experience, education, technical skills, problem-solving ability, and teamwork. A high commit streak might catch their attention, but it's not a deciding factor. Employers are more likely to be impressed by your experience working on real projects, your ability to communicate effectively with others, and your ability to learn quickly and adapt to new situations.
Commit streaks can be faked
Commit streaks are based on the number of commits made to a user's repositories, but they don't account for the quality or significance of those commits. Some users might try to game the system by making superficial changes just to keep their streak going. This means that a high commit streak doesn't necessarily indicate a programmer's commitment to their work or their ability to produce high-quality code.
Other platforms matter too
While GitHub is a popular platform for hosting code, it's not the only platform that matters to employers. Some employers might be more interested in your contributions to other platforms, such as GitLab, Bitbucket, or even your personal website. What matters most is your ability to showcase your skills and experience effectively, regardless of the platform.
Commit streaks aren't everything
Finally, it's important to remember that commit streaks aren't everything. GitHub is just one tool for showcasing your skills and experience, and there are many other ways to demonstrate your abilities to potential employers. For example, you could create a portfolio website, contribute to open-source projects, or participate in coding challenges and hackathons. These activities can be more meaningful and impactful than simply maintaining a high commit streak on GitHub.

In conclusion, your GitHub commit streak might be impressive, but it's not a reliable indicator of your skills or your ability to get a job. Employers care about a variety of factors when hiring programmers, and a high commit streak is just one small piece of the puzzle. So don't worry too much about your commit streak – instead, focus on building real-world experience, learning new skills, and demonstrating your abilities in a variety of ways.
