NPM-UPDATE(1)               General Commands Manual              NPM-UPDATE(1)

NAME
       npm-update

Synopsis
       <!-- AUTOGENERATED USAGE DESCRIPTIONS -->

Description
       This command will update all the packages listed to the latest version
       (specified by the tag config), respecting the semver
       constraints of both your package and its dependencies (if they also re-
       quire the
       same package).

       It will also install missing packages.

       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.

       Note that by default npm update will not update the  semver  values  of
       direct
       dependencies in your project package.json, if you want to also update
       values in package.json you can run: npm update --save (or add the
       save=true option to a configuration file
       to make that the default behavior).

Example
       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 do not satisfy ~1.1.1, which
       is
       equivalent to >=1.1.1 <1.2.0.  So the highest-sorting version that sat-
       isfies
       ~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)

   Subdependencies
       Suppose your app now also has a dependency on dep2
         {
           "name": "my-app",
           "dependencies": {
               "dep1": "^1.0.0",
               "dep2": "1.0.0"
           }
         }

       and dep2 itself depends on this limited range of dep1
         {
         "name": "dep2",
           "dependencies": {
             "dep1": "~1.1.1"
           }
         }

       Then npm update will install dep1@1.1.2 because that is the highest
       version that dep2 allows.  npm will prioritize having a single version
       of dep1 in your tree rather than two when that single version can
       satisfy the semver requirements of multiple dependencies in your tree.
       In this case if you really did need your package to use a newer version
       you would need to use npm install.

   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.
