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

To update one dependency to its lastest version without having to manually open the package.json and change it, you can run

npm install {package-name}@* {save flags?}

i.e.

npm install express@* --save

For reference, npm-install

Update: Recent versions may need latest flag instead, i.e. npm install express@latest

As noted by user Vespakoen on a rejected edit, it's also possible to update multiple packages at once this way:

npm install --save package-nave@* other-package@* whatever-thing@*

He also apports a one-liner for the shell based on npm outdated. See the edit for code and explanation.

PS: I also hate having to manually edit package.json for things like that ;)
