How to update each dependency in package.json to the latest version?

Question

I copied package.json from another project and now want to bump all of the dependencies to their latest versions since this is a fresh project and I don\'t mind

Answer 1

Updated for latest NPM

npm 2+ (Node 0.12+):

npm outdated
npm update
git commit package-lock.json

Ancient npm (circa 2014):

npm install -g npm-check-updates
npm-check-updates
npm shrinkwrap
git commit package-lock.json

Be sure to shrinkwrap your deps, or you may wind up with a dead project. I pulled out a project the other day and it wouldn't run because my deps were all out of date/updated/a mess. If I'd shrinkwrapped, npm would have installed exactly what I needed.

For the curious who make it this far, here is what I recommend:

Use npm-check-updates or npm outdated to suggest the latest versions.

# `outdated` is part of newer npm versions (2+)
$ npm outdated
# If you agree, update.  
$ npm update

#       OR

# Install and use the `npm-check-updates` package.
$ npm install -g npm-check-updates
# Then check your project
$ npm-check-updates
# If you agree, update package.json.
$ npm-check-updates -u

Then do a clean install (w/o the rm I got some dependency warnings)

$ rm -rf node_modules
$ npm install 

Lastly, save exact versions to npm-shrinkwrap.json with npm shrinkwrap

$ rm npm-shrinkwrap.json
$ npm shrinkwrap

Now, npm install will now use exact versions in npm-shrinkwrap.json

If you check npm-shrinkwrap.json into git, all installs will use the exact same versions.

This is a way to transition out of development (all updates, all the time) to production (nobody touch nothing).

• npm outdated

• npm-check-updates

• npm shrinkwrap
