The article provides a comprehensive guide on utilizing references (refs) in Vue.js, an essential feature for interacting with and manipulating DOM elements. It begins by discussing the prerequisites for setting up a Vue.js environment, including Node.js, npm, and Vue CLI installation. The tutorial explains how refs are used to register HTML elements in Vue templates, offering an efficient alternative to JavaScript's getElementById by providing direct access to DOM elements. It further explores how refs can be manipulated within Vue instances, both inside and outside, while noting that refs are not reactive data properties and do not appear in the template inspection. The integration of refs with Vue 3’s Composition API is highlighted, demonstrating how refs can store reactive values and interact with other Composition API features like watch and computed. The article also covers the use of Vue watchers to monitor changes in reactive data, perform actions, and synchronize data across components. It concludes by discussing changes introduced in Vue 3, such as the Composition API and improved TypeScript support for refs, while cautioning against using refs in computed properties due to potential direct manipulation of child nodes. The article emphasizes the importance of correct syntax and provides examples to illustrate the concepts, offering insights into debugging and monitoring Vue applications using tools like LogRocket.
