auto-version-js is a light & fast NPM library to automatically increase the version number of a package.

First, install the npm package :

npm i -D auto-version-js

Then to increment the version number, simply run :

npx auto-version --patch  # +0.0.1
npx auto-version --minor  # +0.1.0
npx auto-version --major  # +1.0.0
npx auto-version          # no args is equivalent to --patch

To implement it in your package.json file :

"scripts": {
    "publish": "npx auto-version && npm publish"
}

In this library, versionString represents a version as a string : '1.2.3' and versionObject represents a version as an object : { major: 1, minor: 2, patch: 3 }

AutoVersion

VersionObject : Object

• AutoVersion
  • .getLocalPath() ⇒ string
  • .getPackageJSON([pathname]) ⇒ JSON
  • .getVersion([pathname]) ⇒ string
  • .setVersion(version, [pathname], [indentation])
  • .parse(versionString) ⇒ VersionObject
  • .stringify(versionObject) ⇒ string
  • .toSemver(versionString) ⇒ string
  • .increment(version, level) ⇒ string
  • .major(version) ⇒ string
  • .minor(version) ⇒ string
  • .patch(version) ⇒ string

Return the path of the project

Returns: string - the path of the project where the package.json is located

Return the package.json file of the project

Returns: JSON - the package.json

Return the current version of the project

Returns: string - the version number

Example

AutoVersion.getVersion()              // --> the version of the current project | ex : 0.5.2
AutoVersion.getVersion('../any/dir')  // --> the version of the project in this directory

Write the version number into package.json

Example

AutoVersion.setVersion('0.2.3')
AutoVersion.setVersion('0.2.3', '../any/dir')
AutoVersion.setVersion('0.2.3', '../any/dir', 4)  // the package.json will be indented with 4 spaces

Extract the major, minor & patch number from a semver version number

Example

AutoVersion.parse('1.4.2')  // --> {major: 1, minor: 4, patch: 2}

Stringify a versionObject

Returns: string - the version representation of the string

Example

AutoVersion.stringify({major: 1, minor: 4, patch: 2})  // --> '1.4.2'

Convert a version into semver standard

Returns: string - the semver version number

Example

AutoVersion.toSemver('1.3.5')      // --> '1.3.5'
AutoVersion.toSemver('1.3')        // --> '1.3.0'
AutoVersion.toSemver('v1.3.5')     // -->  '1.3.5'
AutoVersion.toSemver('version 3')  // -->  '3.0.0'

Increment the version number

Returns: string - the incremented version number

Example

AutoVersion.increment('0.4.7', 'patch')  // --> '0.4.8'
AutoVersion.increment('0.4.7', 'minor')  // --> '0.5.0'
AutoVersion.increment('0.4.7', 'major')  // --> '1.0.0'

Update the version number for a major update

Returns: string - the new version number

Example

AutoVersion.major('1.0.0')  // --> '2.0.0'
AutoVersion.major('0.5.9')  // --> '1.0.0'

Update the version number for a minor update

Returns: string - the new version number

Example

AutoVersion.minor('1.0.0')  // --> '1.1.0'
AutoVersion.minor('0.5.8')  // --> '0.6.0'

Update the version number for a patch update

Returns: string - the new version number

Example

AutoVersion.patch('1.0.0')  // --> '1.0.1'
AutoVersion.patch('0.5.9')  // --> '0.5.10'

Properties

Example

{major: 1, minor: 3, patch: 7}  // represents 1.3.7
