Because of tools like Google search, app users have a genuine appreciation for autocomplete. The more characters the user types into the Google search box, the better the selectable options that are displayed below.
This functionality improves the user experience of a Web Application to be able to choose from a list of suggestions as a user begins entering info into an input field. This is why for React Developers, an Autocomplete component is a useful React component to have.
For example, should an app user really have to type in the full name of the country he resides in when entering his billing address into a form? It would make more sense for a user who lives in the United States to be able to type in the first few characters of the country and them only have to choose between options like ‘United States’ and ‘United Kingdom.’ Or maybe the user just needs the country code. In this case, the user can select ‘United States’ using Autocomplete and then the country code ‘US’ of the United States populates the input box of the form.
There are a number of ways to implement autocomplete functionality within a React Js Application. For example, in the ReactJS Github account, you’ll see a react-autocomplete project developers can use in their React projects. Unfortunately, the latest version of this library was released in 2018, and the repo has been archived by the owner.
Don’t worry, React Web Developers, there are others. We’ll discuss a few of them.
A Few Different React Autocomplete Implementations
Of course, you can create your own Autocomplete component. What ready-made components simplify is something like the implementation of event handlers.
A React component with autocomplete functionality is included within the Material UI framework. It not only includes an Autocomplete component but also exposes a useAutocomplete() hook. The Autocomplete component itself is built on that hook.
Another way of implementing autocomplete functionality is by leveraging a search engine called Algolia. To do so you’d have to install Algolia’s @algolia/autcomplete-js library. Below is an example of an Autocomplete React component created using this library:
