NPM-UPDATE(1)							 NPM-UPDATE(1)

NAME
       npm-update - Update a package

   Synopsis
	 npm update [-g] [<pkg>...]

	 aliases: up, upgrade

   Description
       This  command will update all the packages listed to the	latest version
       (specified by the tag config), respecting semver.

       It will also install missing packages. As with all  commands  that  in-
       stall  packages,	 the  --dev flag will cause devDependencies to be pro-
       cessed as well.

       If the -g flag is specified, this  command  will	 update	 globally  in-
       stalled packages.

       If no package name is specified,	all packages in	the specified location
       (global or local) will be updated.

       As of npm@2.6.1,	the npm	update will only inspect  top-level  packages.
       Prior  versions of npm would also recursively inspect all dependencies.
       To get the old behavior,	use npm	--depth	9999 update.

       As of npm@5.0.0,	the npm	update will change package.json	 to  save  the
       new  version  as	the minimum required dependency. To get	the old	behav-
       ior, use	npm update --no-save.

   Example
       IMPORTANT VERSION NOTE: these examples assume npm@2.6.1 or later.   For
       older  versions	of npm,	you must specify --depth 0 to get the behavior
       described below.

       For the examples	below, assume that the current package is app  and  it
       depends	on dependencies, dep1 (dep2, ..	etc.).	The published versions
       of dep1 are:

	 {
	   "dist-tags":	{ "latest": "1.2.2" },
	   "versions": [
	     "1.2.2",
	     "1.2.1",
	     "1.2.0",
	     "1.1.2",
	     "1.1.1",
	     "1.0.0",
	     "0.4.1",
	     "0.4.0",
	     "0.2.0"
	   ]
	 }

   Caret Dependencies
       If app's	package.json contains:

	 "dependencies": {
	   "dep1": "^1.1.1"
	 }

       Then npm	update will install dep1@1.2.2,	because	1.2.2  is  latest  and
       1.2.2 satisfies ^1.1.1.

   Tilde Dependencies
       However,	if app's package.json contains:

	 "dependencies": {
	   "dep1": "~1.1.1"
	 }

       In  this	case, running npm update will install dep1@1.1.2.  Even	though
       the latest tag points to	1.2.2, this version does not  satisfy  ~1.1.1,
       which  is equivalent to >=1.1.1 <1.2.0.	So the highest-sorting version
       that satisfies ~1.1.1 is	used, which is 1.1.2.

   Caret Dependencies below 1.0.0
       Suppose app has a caret dependency on a version below 1.0.0, for	 exam-
       ple:

	 "dependencies": {
	   "dep1": "^0.2.0"
	 }

       npm update will install dep1@0.2.0, because there are no	other versions
       which satisfy ^0.2.0.

       If the dependence were on ^0.4.0:

	 "dependencies": {
	   "dep1": "^0.4.0"
	 }

       Then npm	update will install dep1@0.4.1,	 because  that	is  the	 high-
       est-sorting version that	satisfies ^0.4.0 (>= 0.4.0 <0.5.0)

   Updating Globally-Installed Packages
       npm  update  -g will apply the update action to each globally installed
       package that is outdated	-- that	is, has	a version  that	 is  different
       from wanted.

       Note:  Globally installed packages are treated as if they are installed
       with a caret semver range specified. So if you  require	to  update  to
       latest you may need to run npm install -g [<pkg>...]

       NOTE: If	a package has been upgraded to a version newer than latest, it
       will be downgraded.
