NPM to download and use the code will be released when exposed to the version number. NPM using semantic version number to manage the code, here briefly.
Semantic version XYZ is divided into three, representing the major version number, minor version number and patch version numbers. When the code is changed, the version number of the update follow these guidelines.
- If only fix bug, need to update the Z position.
- If you are a new feature, but backward compatible, needs to be updated Y position.
- If there are big changes, not downward compatible, needs to be updated X position.
With this assurance the version number, when the third party package dependencies stated, in addition to rely on a fixed version, it can also depend on a range of the version number. For example "argv": "0.0.x" represents dependent on the 0.0.x series, the latest version of argv.
