Depends on what packages you use and how well they do semver. Chances are you will get major version bumps for most of your dependencies after 1-2 years of development.

What works well then is to do upgrades partially. Each major library separately, fix issues, go with the next one. Otherwise it's hard(er) to track what breaks your app.

My current project has 100 dependencies and 150 devDependencies. Upgrading takes a week if not longer for one experienced dev. We tend to do it every 3-4 months.
