Updating Ruby and JavaScript Dependencies

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

Node/Yarn

Checking for Outdated Packages

Check for outdated versions of packages:

cd client
yarn outdated

Read CHANGELOGs of major updated packages before you update. You might not be ready for some updates.

Updating All Dependencies

Option 1: Using npm-check-updates (Recommended)

Install npm-check-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
```

Option 2: Using yarn upgrade

To update all dependencies:

cd client
yarn upgrade

To upgrade a specific package:

yarn upgrade [package]

Adding New Dependencies

Typically, you can add your Node dependencies as you normally would:

cd client
yarn add module_name@version
# or for dev dependencies
yarn add --dev module_name@version

Verify After Updates

Confirm that the hot replacement dev server and the Rails server both work after updating dependencies.
