javascript - How do I update each dependency in package.json to the latest version? -


i copied package.json project , want bump of dependencies latest versions since fresh project , don't mind fixing if breaks.

what's easiest way this?

the best way know of run npm info express version update package.json manually each one. there must 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 these bumped latest?     "mongodb": "~1.2.5",     "underscore": "~1.4.2",     "rjs": "~2.9.0",     "jade": "~0.27.2",     "async": "~0.1.22"   } }

i collaborator on npm-check-updates, great solution problem.

i have been actively maintaining npm-check-updates last 8 months. v2 released few weeks ago, containing simplified output , many bug fixes , new options. enjoy.

looks npm-check-updates way make happen now.

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

on npm <3.11:

simply change every dependency's version *, run npm update --save. (note: broken in recent (3.11) versions of npm).

  "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, blunt hammer of updating dependencies. it's fine if—as said—the project empty , nothing can break.

on other hand, if you're working in more mature project, want verify there no breaking changes in dependencies before upgrading.

to see modules outdated, run npm outdated. list installed dependencies have newer versions available.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
