npm uses Semantic Versioning. Given a version number MAJOR.MINOR.PATCH, increment the:
- MAJOR version when you make incompatible API changes,
- MINOR version when you add functionality in a backwards compatible manner, and
- PATCH version when you make backwards compatible bug fixes.
Additional labels for pre-release and build metadata are available as extensions to the MAJOR.MINOR.PATCH format, e.g. 1.0.0-alpha.
To specify acceptable version ranges up to 1.0.4, use the following syntax:
- Patch releases:
1.0or1.0.xor~1.0.4 - Minor releases:
1or1.xor^1.0.4 - Major releases:
*orx
| Symbol | Rule | Example |
|---|---|---|
^ |
accept updates to minor and patch releases only. | ^0.13.0: 0.13.1, 0.14.0 |
~ |
accept updates to patch releases only. | ~0.13.0: 0.13.1 (not 0.14.0) |
> |
accept updates to any version greater than the one specified. | >0.13.0: 0.13.1, 0.14.1, 1.1.1 |
< |
accept updates to any version less than the one specified. | <3.0.0: 2.0.0, 2.9.0 |
>= |
accept any version greater than or equal to the one specified. | >=3.0.0: 3.0.0, 4.1.0 |
<= |
accept any version less than or equal to the one specified. | <=3.0.0: 3.0.0, 4.1.0 |
= |
accept only the exact specified version. | =3.0.0: 3.0.0, (not 3.0.1) |
- |
accept a range of versions. | 1.0.0 - 1.10.10: 1.5.0 (not 1.11.0) |
|| |
accept a combination of versions. | <2.1.0 || >2.6.0: 2.0.1, 3.1.0 |
x.x.x |
accept only the specified version (no symbol). | =3.0.0: 3.0.0, (not 3.0.1) |
latest |
always get latest version available. | - |
Thanks for this! I think this example is wrong:
<= | accept any version less than or equal to the one specified. | <=3.0.0: 3.0.0, 4.1.0
should be something like:
<= | accept any version less than or equal to the one specified. | <=3.0.0: 3.0.0, 2.9.0 (not 4.1.0)
