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.
EXAMPLES
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)
Recording Updates with --save
When you want to update a package and save the new version as
the minimum required dependency in
package.json, you can use
npm update -S or
npm update --save. For example if
package.json contains:
-
"dependencies": {
"dep1": "^1.1.1"
}
Then
npm update --save will install
dep1@1.2.2 (i.e.,
latest),
and
package.json will be modified:
-
"dependencies": {
"dep1": "^1.2.2"
}
Note that
npm will only write an updated version to
package.json
if it installs a new package.
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
latest.
NOTE: If a package has been upgraded to a version newer than
latest, it will
be
downgraded.
