Quick tool generation with VueJS, Tailwind CSS and LocalStorage

Before: Tools with Excel

I used to write down the total number of tasks in a row in Excel and add a row for my done tasks. I would add a ratio row and do the math to see my progress.

That setup is flexible and worked pretty well, but it looked boring. Well, just like an Excel sheet looks like.

I need to confess that visuals make a huge motivation difference for me.

After: Tools with JS, CSS, LocalStorage

That is why I need a good toolbox for creating helpers that are…

  • Easy to implement
  • Easy to adjust and extend
  • Looking nice

The modern web universe has such tools:

  • TailwindCSS lets me write beautiful yet flexible UIs in minutes not hours
  • VueJS is a drop-in extension to make my HTML dynamic without adding extra tooling
  • LocalStorage lets me persist all the data that I enter and process

Here is how my little example task progress tracker looks like using these tools:

VueJS Todo Counter

Let me do a quick tour of the feature that I use frequently to build tools like this task tracker:

  • TailwindCSS from CDN: In JSBin I have a boilerplate with Tailwind so the page looks good from line 1 <link href="https://cdn.jsdelivr.net/npm/tailwindcss/dist/tailwind.min.css" rel="stylesheet">
  • Antialiasing <body class="antialiased"> - This smoothes all fonts
  • VueJS from CDN <script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.0.3/vue.js"></script> Pull in VueJS to make the page dynamic
  • Quick role-model-binding To fetch my entries and process them with VueJS, I add a simple v-model: <input v-model=“tasks.done” name=“done">

The actual power comes from a few lines of JavaScript. Let me explain with inline comments

var app = new Vue({},
computed: { /* Calculate the ratio */
    ratio: function() {
        return Math.floor(this.tasks.done / this.tasks.total * 100) + '%'
watch: { /* Observe changes and write to LocalStorage */
    tasks: {
        handler() {
            console.log('Tasks changed');
            localStorage.setItem('tasks', JSON.stringify(this.tasks));
        deep: true,
mounted() { /* Load values from LocalStorage and load */
    console.log('App mounted');
    if (localStorage.getItem('tasks')) this.tasks = JSON.parse(localStorage.getItem('tasks'));

Write endless simple tools with this setup

The combination of the three technologies (HTML + CSS Framework, JavaScript, LocalStorage) makes it super easy to create simple yet flexible and beautiful tools.

Other tools that I built the same way:

  • Day and pomodoro planner
  • Customized todo app
  • Cryptocurrency price tracker (using jQuery’s $.getJSON('API-URI') as I did not find a drop in replacement for VueJS)

There are endless opportunities to create flexible and good-looking tools for your specific needs in very little time!
