Caret Ranges ^1.2.3 ^0.2.5 ^0.0.4§
Allows changes that do not modify the left-most non-zero digit in the
[major, minor, patch]
tuple. In other words, this allows patch and minor updates for versions
1.0.0
and above, patch updates for versions
0.X >=0.1.0
, and
no
updates for versions
0.0.X
.
Many authors treat a
0.x
version as if the
x
were the major “breaking-change” indicator.
Caret ranges are ideal when an author may make breaking changes between
0.2.4
and
0.3.0
releases, which is a common practice. However, it presumes that there will
not
be breaking changes between
0.2.4
and
0.2.5
. It allows for changes that are presumed to be additive (but non-breaking), according to commonly observed practices.
实际使用情况如下：
-
^1.2.x:=>=1.2.0 <2.0.0 -
^0.0.x:=>=0.0.0 <0.1.0 -
^0.0:=>=0.0.0 <0.1.0
A missing
minor
and
patch
values will desugar to zero, but also allow flexibility within those values, even if the major version is zero.
-
^1.x:=>=1.0.0 <2.0.0 -
^0.x:=>=0.0.0 <1.0.0
