What methods can I use to ensure clients refresh their JavaScript files?

Currently, we are in a private beta phase and making frequent updates. However, we face the issue where clients’ browsers continue to use the cached JavaScript files after deploying updates, preventing them from seeing the latest changes. While we can instruct users to perform a ctrlF5 refresh during support calls, we would prefer a more automated solution. One approach we are considering is appending version numbers to our JavaScript file names and incrementing these with each release. While this method works, it could become tedious to update all references every time. I would love to hear from the community about how you handle cache updates for your clients. Are there more efficient strategies you employ to ensure users receive updated files?

An effective way to bypass cache without manual effort is to implement cache busting techniques. Here are two common approaches:

  1. Query String Versioning: Append a version number or timestamp to your file URL. E.g., script.js?v=1.2.3. Alter it with each deploy.
  2. Service Workers: Use service workers to manage caching dynamically, providing more control over cache strategies.

This helps ensure users access the latest version without manual cache clearing.
