I am looking for the command in a program that filters only when 3 letters are entered

Question

I am looking for the command in a program that filters only when 3 letters are entered. Does anyone know what command or code I need to look for to find this?

Maybe it's also a Vue-Command, because my program is written in Vue.js.

Thank you

Pass the search input to a function first then validate the input. If passes the validation, proceed with searching.

Assuming this is your search input

<input v-model="searchInput"/>

Add an input event handler

<input v-model="searchFor" @input="searchHandler"/>

Then validate the search input with searchHandler method

new Vue({

  methods: {
    searchHandler (text) {
      if(text.length > 2){
      // Write your code on here
      }
    }
  }

})
