Vue Js Auto Resize Textarea: In  Vue.js, you can create an auto-resizing textarea component by binding a method to the “input” event of the textarea. The method updates the height of the textarea based on its content using the scrollHeight property. To make the component responsive, you can use CSS to set the initial height of the textarea to a minimum value and set its max-height to a value that matches the height of the parent container. By doing this, the textarea will expand vertically as the user types and reaches the max-height limit. You can also use CSS transitions to create a smooth animation effect as the textarea resizes.

What is the process for creating an auto-resizing textarea component in Vue.js?

This is a code snippet written in Vue.js, a popular front-end  JavaScript framework. It creates a text area inside a div with an ID of “app”. The text area has a placeholder text and a single row.

The Vue instance creates a data object with a single property called “text”, which is initially set to an empty string. The “mounted” lifecycle hook is used to call the “resizeTextarea” method, which sets the height of the text area to auto and then sets it to the scroll height of the text area.

The “resizeTextarea” method is triggered whenever the user types in the text area, thanks to the “@input” event listener. It updates the height of the text area to fit the user’s input dynamically.

Overall, this code creates a responsive text area that grows or shrinks depending on the length of the user’s input.

            },

                resizeTextarea() {
                    this.$refs.textarea.style.height = "auto";
                    this.$refs.textarea.style.height = `${this.$refs.textarea.scrollHeight}px`;
                },

        })
