Introduction to Using API: Reference and Configurations of Next.js for ETag Management
When you are working with JavaScript frameworks like Next.js, one of the things that might come up often is the concept of ETags. You might wonder what ETags are and how they can help you. Well, simply put, an ETag is a unique identifier for a version of a cached page, which helps the browser determine whether it needs to request the page from the server again or not.
This actually happens when the request has been made to the server. If ETags are enabled, addresses that haven't changed will not request again, meaning they can be fetched from the cache.
Interestingly, the following is a predefined file
next.config.js that will be used when you configure it. By configuring this file, you can define types and actions, such as ETag, for processing. However, it should be noted that not effectively using or lacking the configuration of this feature can potentially cause performance issues on your site.
Another interesting point about ETags is that when your browser interacts with the server, if ETags are active, unchanged addresses won’t request again, which can occur both at the same time and during continuous rice processing.
Many large sites that are heavily dependent on performance utilize ETags, which significantly impacts user experience and site speed. Therefore, it is also relevant to note that adjusting its configurations improves performance.
Now let's take a quick look at the code and see how we can activate ETags.
module.exports = {\r\n generateEtags: true, \/\/
