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

The following code (which was accepted) wrote me something like "it takes too long blah-blah" and did nothing. Probably using the global flag was the problem, idk.

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

I decided to use my text editor and follow a semi-manual approach instead.

I copied a list like this (just a lot longer) from the dev dependencies of my package.json to the notepad++ text editor:

"browserify": "10.2.6",
"expect.js": "^0.3.1",
"karma": "^0.13.22",
"karma-browserify": "^5.2.0",

I set the search mode to regular expression, used the ^\s*"([^"]+)".*$ pattern to get the package name and replaced it with npm uninstall \1 --save-dev \nnpm install \1 --save-dev. Clicked on "replace all". The otput was this:

npm uninstall browserify --save-dev 
npm install browserify --save-dev
npm uninstall expect.js --save-dev 
npm install expect.js --save-dev
npm uninstall karma --save-dev 
npm install karma --save-dev
npm uninstall karma-browserify --save-dev 
npm install karma-browserify --save-dev

I copied it back to bash and hit enter. Everything was upgraded and working fine. That's all.

"browserify": "^16.1.0",
"expect.js": "^0.3.1",
"karma": "^2.0.0",
"karma-browserify": "^5.2.0",

I don't think it is a big deal, since you have to do it only every now and then, but you can easily write a script, which parses the package.json and upgrades your packages. I think it is better this way, because you can edit your list if you need something special, for example keeping the current version of a lib.
