Package Exports

sort-package-json

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (sort-package-json) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Sort Package.json

CLI

Run via npx (npm@5.2+ required)

npx sort-package-json

Install

npm install --global sort-package-json

Usage

$ cd my-project
$ cat package.json
{
  "dependencies": {
    "sort-package-json": "1.0.0",
    "sort-object-keys": "1.0.0"
  },
  "version": "1.0.0",
  "name": "my-awesome-project"
}

$ npx sort-package-json
package.json is sorted!

$ cat package.json
{
  "name": "my-awesome-project",
  "version": "1.0.0",
  "dependencies": {
    "sort-object-keys": "1.0.0",
    "sort-package-json": "1.0.0"
  }
}

CLI also supports multi file paths or glob - so you can give it a bunch of package.json file(s) to sort.

$ sort-package-json "my-package/package.json" "other-package/package.json"

$ sort-package-json "package.json" "packages/*/package.json"

`--check` flag

When you want to check if your files are sorted, you can run CLI with the --check flag (or -c). This will output a list of not sorted files, if any.

$ sort-package-json "**/package.json" --check

# 5 matched files are sorted.


$ sort-package-json "**/package.json" --check
# foo/package.json
# bar/package.json

# 2 of 5 matched files are not sorted.

API

Install

npm install --save-dev sort-package-json

Usage

sortPackageJson(packageJson, options?)

Pass a JSON string, return a new sorted JSON string.
Pass a JSON object, return a new sorted JSON object.

const sortPackageJson = require('sort-package-json')

const packageJsonString = `{
  "dependencies": {
    "sort-package-json": "1.0.0",
    "sort-object-keys": "1.0.0"
  },
  "version": "1.0.0",
  "name": "my-awesome-project"
}`

console.log(sortPackageJson(packageJsonString))
/* => string:
{
  "name": "my-awesome-project",
  "version": "1.0.0",
  "dependencies": {
    "sort-object-keys": "1.0.0",
    "sort-package-json": "1.0.0"
  }
}
*/

const packageJsonObject = JSON.parse(packageJsonString)
console.log(sortPackageJson(packageJsonObject))
/* => object:
{
  name: 'my-awesome-project',
  version: '1.0.0',
  dependencies: {
    'sort-object-keys': '1.0.0',
    'sort-package-json': '1.0.0'
  }
}
*/

options.sortOrder

Type: string[] | Function
Default: sortPackageJson.sortOrder

Custom ordering array or comparator function.

If an array, sort keys in ordering of options.sortOrder.

Notice: fields not in this array, will still sort by defaultSortOrder

const sorted = sortPackageJson(packageJsonObject, {
  sortOrder: ['version']
})

console.log(Object.keys(sorted))

// -> [ 'version', 'name', 'dependencies' ]
//                 ^^^^^^^^^^^^^^^^^^^^^^
//                 `name` and `dependencies` are sorted by defaultSortOrder

If a function, sort fields by Array#sort(options.sortOrder)

const sorted = sortPackageJson(packageJsonObject, {
  sortOrder(left, right) {
    return left.localeCompare(right)
  }
})

console.log(Object.keys(sorted))

// -> [ 'dependencies', 'name', 'version' ]

Supported Libraries

Alphabetically ordered.

Automatically Sort

The package.json file can be sorted automatically before committing, install husky and lint-staged and add the following to your package.json file:

{
  "husky": {
    "hooks": {
      "pre-commit": "lint-staged"
    }
  },
  "lint-staged": {
    "package.json": [
      "sort-package-json",
      "git add"
    ]
  }
}

PFAQ: Potential Frequently Asked Questions

How does it sort?

It sorts using sort-object-keys. It sorts using the well-known keys of a package.json. For the full list it's just easier to read the code. It sorts sub-keys too - sometimes by a well-known order, other times alphabetically. The initial order was derived from the package.json docs with a few extras added for good measure.

It doesn't sort X?

Cool. Send a PR! It might get denied if it is a specific vendor key of an unpopular project (e.g. "my-super-unknown-project"). We sort keys like "browserify" because it is a project with millions of users. If your project has, say, over 100 users, then we'll add it. Sound fair?

Isn't this just like Project X?

Could be. I wanted this one because at the time of writing, nothing is:

Zero config
Able to be used in a library
Quiet (i.e. not spitting out annoying log messages, when used in a library mode)

What?! Why would you want to do this?!

Well, it's nice to have the keys of a package.json in a well sorted order. Almost everyone would agree having "name" at the top of a package.json is sensible (rather than sorted alphabetically or somewhere silly like the bottom), so why not the rest of the package.json?
