A major version upgrade with no configuration change, on a build that had already been reduced to a proxy declaration.
export default {
server: { proxy: { '/api': 'http://localhost:8080' } },
}
// the upgrade: a version bump and a Node minimum we
// exceeded. twenty minutes, most of it reading which
// of our zero remaining options had changed.
A configuration that has shrunk to one line is a configuration that cannot break on an upgrade, which is the durable benefit of the 2025 exercise rather than the build being faster. Most of the options removed then were describing defaults that the tool had since adopted.
