library0.2.0jsnpmunverified

A Node.js library (v0.2.0, last updated February 2015) for updating or linting a package.json file against a set of defaults. Originally designed to enforce consistent fields across multiple projects, it appears to read a template/defaults object and merge it into an existing package.json. The package is minimal, using only Node's built-in fs and path modules, and has no significant external dependencies. Its development cadence is very low (single release), and it has been largely superseded by more active tools like sort-package-json or npm-check. The project is now archived/unmaintained.

default
✓ const updatePkg = require('update-package')
✗ import updatePkg from 'update-package'
Package uses CJS, no ESM export. Requires Node >=0.10.0.
none (callable)
✓ const updatePkg = require('update-package')(defaults, pkg)
✗ const updatePkg = new (require('update-package'))(defaults, pkg)
Function returns a modified package.json object; no constructor.
none (type)
✓ const updatePkg = require('update-package')
No TypeScript types provided; use @types/update-package if available (not on DefinitelyTyped).

Shows how to require the package and use it to update a package.json object with default values.

const updatePkg = require('update-package'); const defaults = { name: 'my-app', version: '1.0.0' }; const pkg = { name: 'my-app', version: '0.9.0', private: true }; const result = updatePkg(defaults, pkg); console.log(result); // { name: 'my-app', version: '1.0.0', private: true }
Debug
Known issues
deprecatedPackage is unmaintained since 2015. Use modern alternatives like sort-package-json or npm init.
fix
Use sort-package-json or migrate to npm's built-in defaults.
affects: >=0.0.0
gotchaThe function mutates the first argument (defaults) and returns it; does not create a deep copy.
fix
Pass a shallow copy of defaults: updatePkg({...defaults}, pkg)
affects: <=0.2.0
gotchaOnly works with CommonJS require; not ESM compatible and no dual build.
fix
Use dynamic import or rewrite to use require.
affects: <=0.2.0
deprecatedNo longer maintained; known issues with npm v2+ and newer Node versions may cause unexpected behavior.
fix
Switch to a maintained alternative.
affects: >=0.0.0
