// Nuxt 3 approach: please follow the link below as an example on how to use it as a plugin
// https://stackoverflow.com/a/74694711/245030

1. Limit and Count text.

   <div>
       <textarea></textarea>
       <!-- Class helpers -->
       <!-- Current counter class -->
       <span class="reactiveTextArea_curCount"></span>
       <!-- Remainder counter class -->
       <span class="reactiveTextArea_remCount"></span>
       <!-- Maximum allowed texts or words class -->
       <span class="reactiveTextArea_maxAllowed"></span>
   </div>

   reactiveTextArea.config({
       // Enable counting
       enableCounter: true
       countOrLimitType: "word" // "text" or "word"
   
       // Enable and set limit
       enableLimiter: true
       maxAllowed: 90
   
       // set textarea element
       element: document.querySelector('textarea')
   });
   
   reactiveTextArea.init();

2. Filter: restrict some words based on filter list

   <div>
       <textarea></textarea>
       <!-- No of filtered words count class -->
       <span class="reactiveTextArea_filterCount"></span>
   </div>

   reactiveTextArea.config({
       // Enable filter
       enableFilter: true,
       wordsToFilter: ["dumb", "shit"],
       enableStrictFiltering: false
   
       // set textarea element
       element: document.querySelector('textarea')
   });
   
   reactiveTextArea.init();

3. Explore the limitless through Custom Function

   <!--HTML -->
   <textarea></textarea>
   <div>
       <span>0</span>
       <!--- HR element progress in width as the user types -->
       <hr />
   </div>

   /** CSS **/
   div {
       display: flex;
       flex-direction: row;
   }
   
   div hr {
       display: inline block;
       height: 1px;
       width: 0;
       border: 1px solid #000;
   }

   reactiveTextArea.config({
       // Enable counting
       enableCounter: true
       countOrLimitType: "text"
   
       // Enable and set limit
       enableLimiter: true
       maxAllowed: 120
   
       // Enable filter
       enableFilter: true,
       wordsToFilter: ["mad", "stupid"],
       enableStrictFiltering: true
   
       // Callback function
       callbackFunc: logAll
   
       // set textarea element
       element: document.querySelector('textarea')
   });
   
   reactiveTextArea.init();
   
   // Custom function
   
   let progress = document.querySelector('hr');
   
   function logAll(args) {
       // This function is exposed to the following helpers
   
       // 1. `args.events`: current event name triggered (copy, paste, etc).
       // 2. `args.inputs`: current texts in the textarea. (str)
       // 3. `args.inputsPercentage`: total texts count in percentage. (num)
       // 4. `args.inputsCount`: total count. (num)
       // 5. `args.noOfInputWords`: total words count. (num)
       // 6. `args.noOfInputTexts`: total texts count. (num)
       // 7. `args.noOfWordsFiltered`: total filtered words. (num)
       // 8. `args.maxAllowed`: max number of words or text allowed. (num)
   
       // eg: log no of words typed
       console.log(args.noOfInputWords);
   
       // HR width gets altered based on the percentage.
       Object.assign(progress.style, {width: args.inputsPercentage + "%"})
   }

Dev feature .reset()

The reactiveTextArea.reset() can be used to reset the plugin output to default.

// Resets callback args and helper classes to default
reactiveTextArea.reset()

// Defaults callback args and helper classes, then clears the textarea input.
reactiveTextArea.reset(true)
