    export default {
      name: 'HelloWorld',
      components : {

    Name Required Type Default Description Reactive
    highlight Yes String or Array null The string or list of words to highlight. This can be a single string value, a RegExp or you can do an array of strings or RegExp or array of Highlight Objects or array of Range Objects. Yes
    highlightEnabled No Boolean true If true, will highlight the text Yes
    highlightStyle No String or Object background-color:yellow If no style is provided for text, this will act as the global styling for the highlight. Can also be a dictionary instead of string. Yes
    highlightDelay No Number 500 Determines how long in milliseconds to wait before processing the highlights. Setting this to a low value is fine for small text but setting it higher may improve performance significantly for larger text Yes
    caseSensitive No Boolean false If true, will treat highlight strings with case sensitivity. Can be overrided per highlight object. Yes
    value No String null Raw text value. Yes
    fireOn No String keydown The dom event on which the highlight event should be fired. This can be any event that the div content editable can handle. No (only because the listener is being added in mounted)
    fireOnEnabled No Boolean true If true, will process the highlights on the specified (or default) event. No (only because the value is used in the mounted function)

    Highlight Object

        text:'chicken', // Required
        style:"background-color:#f37373" // Optional
        caseSensitive: true // Optional defaults to False

        end: 9,  // Required

    Name Description
    @input Just like a regular input html element you can use this to react to input events

    Note, that you can also use v-model

    Some notes

    • This is not meant to be used for large scale text highlight because of how inefficient div contentEditable is and also the fact the algorithm I'm using is stupidly inefficient (try entering like a lot of text for highlighting)
    • Good use cases for this are something like what does (they probably have a more efficient algorithm though) for highlighting recognized entities on the fly.
    • Let me know what other use cases you might have!

    Why make this?

    • I liked the way does highlighting and I wanted to recreate that in Vue.
    • Because I was bored and also had a similar problem at work (No, I wasn't bored at work! Quite the opposite actually.)
    • Because I still know nothing about web development and I'm still a n00b. Roast me bro.
    • Because it looks cool!
