How can I update each dependency in package.json to the latest version?
node.js, npm
Solution
It looks like npm-check-updates is the only way to make this happen now.
npm i -g npm-check-updates
ncu -u
npm install
Or using npx (so you don't have to install a global package):
npx npm-check-updates -u
npm install
On npm <3.11:
Simply change every dependency's version to `*`, then run `npm update --save`. (Note: broken in recent (3.11) versions of npm).
Before:
"dependencies": {
"express": "*",
"mongodb": "*",
"underscore": "*",
"rjs": "*",
"jade": "*",
"async": "*"
}
After:
"dependencies": {
"express": "~3.2.0",
"mongodb": "~1.2.14",
"underscore": "~1.4.4",
"rjs": "~2.10.0",
"jade": "~0.29.0",
"async": "~0.2.7"
}
Of course, this is the blunt hammer of updating dependencies. It's fine if—as you said—the project is empty and nothing can break.
On the other hand, if you're working in a more mature project, you probably want to verify that there are no breaking changes in your dependencies before upgrading.
To see which modules are outdated, just run `npm outdated`. It will list any installed dependencies that have newer versions available.

Problem
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 fixing something if it breaks. What's the easiest way to do this? The best way I know is to run `npm info express version` and then update each dependency in `package.json` manually. There must be a better way. ``` { "name": "myproject", "description": "my node project", "version": "1.0.0", "dependencies": { "express": "^3.0.3", // how do I get these bumped to latest? "mongodb": "^1.2.5", "underscore": "^1.4.2" } } ``` For Yarn-specific solutions, refer to this Stack Overflow question.
