versync使用教程帮助文档

versync

versync is a node.js package that enables you to synchronize version numbers accross package.json and other source files of your choosing.

This software is a fork of semver-sync. The fork was triggered by a desire to support TypeScript. A pull request was put it but after over a week without response I decided to fork because my own projects depend on the enhancement. Many thanks to Alex Ciminian for having produced and leading the development of semver-sync.

Supported Platforms

versync supports Node.js 8 and over.

Installation

You can install it via npm:

npm install -g versync

Note that it is perfectly viable to install versync locally if you want.

Support for TypeScript is optional. If you want it, you need to also install typescript.

How to use it

This utility uses package.json as the reference by which all other version numbers in the package are checked. If you don’t have a package.json in the folder where you run it, it will give an error and break.

The utility automatically checks package.json. If you have other JavaScript sources or JSON files that hold your version number first edit the package.json, adding the versionedSources property:

{
  "name": "mypackage",
  "version": "1.2.3",
  "versionedSources": "mypackage.js"
}

Once that’s done, you can check that everything’s ok:

versync -v
[OK] Everything is in sync, with version number 1.2.3

If you accidentally change the version number in one of the sources, or forget to update it, you’ll see an error:

versync -v
[ERROR] Version number is out of sync in component.json, mypackage.js.

If you want to update the version number automatically in all the files, you can do:

versync -b
[OK] Version number was updated to 1.2.4 in package.json, component.json, mypackage.js.
versync -b patch
[OK] Version number was updated to 1.2.5 in package.json, component.json, mypackage.js.
versync -b minor
[OK] Version number was updated to 1.3.0 in package.json, component.json, mypackage.js.
versync -b major
[OK] Version number was updated to 2.0.0 in package.json, component.json, mypackage.js.
versync -b 3.0.0-alpha1
[OK] Version number was updated to 3.0.1-alpha1 in package.json, component.json, mypackage.js.
versync -b 3.0.0-beta2
[OK] Version number was updated to 3.0.1-beta2 in package.json, component.json, mypackage.js.
versync -b 3.0.0-rc1
[OK] Version number was updated to 3.0.1-rc1 in package.json, component.json, mypackage.js.

If you want to update the version number automatically in all the files, commit the changes and create a new git tag, you can do:

versync -b -t
[OK] Version number was updated to 1.2.4 in package.json, component.json, mypackage.js.
[OK] Files have been commited and tag v1.2.4 was created.

Integration with npm version

If you want to integrate versync with npm version or any tool that sets the version number in package.json and you only want to propagate that version number to other files, you can use -b sync:

versync -b sync
[OK] Version number in files to be synced is 0.0.7.
[OK] Version number was updated to 0.2.0 in assigned.js, es6.js.

If the tool also commits files, you probably want to also use the -a flag:

versync -b sync -a

This allows you to have a version script like this in your package.json:

  "version": "./bin/versync -b sync -a",

What will happen when you run npm version is:

  1. npm will change the version in package.json, and then launch the version script.

  2. versync will synchronise all version numbers with the new one in package.json.

  3. versync will run git add for all synchronised files.

  4. npm will run git add package.json, commit the changes and add a tag.

How it works

The module uses esprima to create an AST of the JavaScript and JSON sources passed in, or it uses TypeScript’s own AST facilities to create an AST of TypeScript sources.

The AST patterns used to find the nodes which hold the version properties are in the patterns.js and tspatterns.ts source files. It should work on most types of structures. If you find a structure that isn’t processed correctly, please submit an issue.

Console help

usage: versync [-h] [-b [BUMP]] [-s SOURCES] [-v] [-a] [-t]

Synchronizes version numbers accross package.json and other source files of
your choosing.

Optional arguments:
  -h, --help            Show this help message and exit.
  -b [BUMP], --bump [BUMP]
                        Bump the version number in the specified source files.
                         It can take one of the following values: "major",
                        "minor", "patch". Or you can use "sync" to copy the
                        version numbers from package.json to the other files.
                        Alternatively you can specify a custom version that
                        is higher than the current one. If no value is
                        specified, it defaults to "patch".
  -s SOURCES, --sources SOURCES
                        Declare the JavaScript files in which the version
                        number will be updated. If this option is not used,
                        the list of files is read from the package.json
                        "versionedSources" property. If the property is not
                        present in the package.json and this option is not
                        used, only package.json will be synced. Optional.
  -v, --verify          Verifies that the sources have the same version
                        number and checks whether this version number
                        conforms to the semver specification.
  -a, --add             After bumping the version number, run `git add` on
                        the versioned files.
  -t, --tag             After bumping the version number, commit the changes
                        and create a git tag with the current version. (Note
                        that using --add with this flag does nothing more
                        than using this flag alone.)

API

You can now import versync and use its exported API. The code in index.js has been commented using JSDoc 3 doclets. We do not yet generate documentation from it, so you have to read the code to read the documentation of the API. In brief, you can now do:

const versync = require("versync");
const runner = new sync.Runner({
  bump: "minor",
});
runner.run().then(() => {
  // Do somehting on success...
});
