Problem:

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

Solution 1:

The best way I know of now is to run npm info express version then update package.json manually for each one. There must be a better way.

{
  "name": "myproject",
  "description": "my node project",
  "version": "1.0.0",
  "engines": {
    "node": "0.8.4",
    "npm": "1.1.65"
  },
  "private": true,
  "dependencies": {
    "express": "~3.0.3", // how do I get these bumped to latest?
    "mongodb": "~1.2.5",
    "underscore": "~1.4.2",
    "rjs": "~2.9.0",
    "jade": "~0.27.2",
    "async": "~0.1.22"
  }
}

Solution 2:

Looks like npm-check-updates is the only way to make this happen now.

npm i -g npm-check-updates
npm-check-updates -u
npm install

On npm <3.11: Simply change every dependency's version to *, then run npm update --save.

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"
  }

Solution 4:

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?}

Solution 5:

  • Use * as the version for the latest releases, including unstable
  • Use latest as version definition for the latest stable version
  • Modify the package.json with exactly the latest stable version number using LatestStablePackages

Here is an example:

"dependencies": {
        "express": "latest"  // using the latest STABLE version
    ,   "node-gyp": "latest"    
    ,   "jade": "latest"
    ,   "mongoose": "*" // using the newest version, may involve the unstable releases
    ,   "cookie-parser": "latest"
    ,   "express-session": "latest"
    ,   "body-parser": "latest"
    ,   "nodemailer":"latest"
    ,   "validator": "latest"
    ,   "bcrypt": "latest"
    ,   "formidable": "latest"
    ,   "path": "latest"
    ,   "fs-extra": "latest"
    ,   "moment": "latest"
    ,   "express-device": "latest"
},
