If you frequently update dependencies in small batches, you will avoid large and painful updates later. Then again, if you don't have good test coverage, it's hazardous to update dependencies at any time.

Ruby

Delete any unwanted version constraints from your Gemfile and run:

bundle update

NPM

Install npm-check-updates
Run yarn outdated and read CHANGELOGs of major updated packages before you update. You might not be ready for some updates.
Run these commands. You may or may not need to rm -rf your node_modules directory.
```
cd client
ncu -u -a
yarn
```

Some combinations that I often run:

remove old installed node_modules so you only get what corresponds to package.json:
```
ncu -u -a && rm -rf node_modules && yarn
```
