util._extend deprecation warning with browser-sync 3.0.3 and NodeJS 22.9.0

[jupelexv]

Issue details

browser-sync (version 3.0.3) is using http-proxy version 1.18.1 which causes deprecation warning with NodeJS 22.9.0:

(node:5602) [DEP0060] DeprecationWarning: The `util._extend` API is deprecated. Please use Object.assign() instead.

The warning likely happens in http-proxy/lib/http-proxy/http-proxy/index.js at line 2: extend = require('util')._extend, (https://github.com/http-party/node-http-proxy/blob/9b96cd725127a024dabebec6c7ea8c807272223d/lib/http-proxy/index.js#L2C5-L2C41).
This expression has been deprecated since NodeJS 22.0.0.
I did not find this issue on any other modules listed in the error message.

There's already an existing issue and suggested solution in http-proxy repository, but has not been applied yet.
Also, worth noting that the latest version ofhttp-proxy was released 4 years ago, so not sure if the whole module has been deprecated.

One suggestion could be using @refactorjs/http-proxy, which is supposed to be a refactored project of http-proxy.

Please specify which version of Browsersync, node and npm you're running

• Browsersync [3.0.3]
• Node [22.9.0]
• Npm [10.8.3]

I have the same warning:
[DEP0060] DeprecationWarning: The util._extend API is deprecated. Please use Object.assign() instead.

Everyting seems to work fine though.

npm: 10.9.2
node: 22.13.1
browsersync: 3.0.3

Also seeing this after switching over to Node v24.1.0. In development I have --trace-deprecation active to more easily debug these sorts of issues. The stack trace is quite noisy in the output.

I know it's not a breaking issue, but the OP's suggestion of switching over to @refactorjs/http-proxy does seem like a good solution.
