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  install  packages,  the
       --dev flag will cause devDependencies to be processed as well.

       If the -g flag is specified, this command will update globally installed 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 behavior, 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 example:

         "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 highest-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.
