Write a
package.jsonfile
Writes atomically and creates directories for you as needed. Sorts dependencies when writing. Preserves the indentation if the file already exists.
npm install write-packageimport path from 'node:path';
import {writePackage} from 'write-package';
await writePackage({foo: true});
console.log('done');
await writePackage(path.join('unicorn', 'package.json'), {foo: true});
console.log('done');Returns a Promise that resolves when the package.json file has been written.

//=> { "foo": false, "bar": true }Type: string
Default: process.cwd()

import {writePackage, addPackageDependencies} from 'write-package';
await writePackage({foo: true});
//=> { "foo": true }
await addPackageDependencies({foo: '1.0.0'});
//=> { "foo": true, "dependencies": { "foo": "1.0.0" } }
await addPackageDependencies({dependencies: {foo: '1.0.0'}, devDependencies: {bar: '1.0.0'}});
//=> { "foo": true, "dependencies": { "foo": "1.0.0" }, "devDependencies": { "bar": "1.0.0" } }Type: string
Default: process.cwd()
The path to where the package.json file should be written or its directory.
Type: Record<string, string> | Partial<Record<'dependencies' | 'devDependencies' | 'optionalDependencies' | 'peerDependencies', Record<string, string>>>
Dependencies to add to the package.json file.
Type: object
See Options.
Returns a Promise that resolves when the package.json file has been written. Does not throw if the file does not exist.
import {writePackage, removePackageDependencies} from 'write-package';
await writePackage({foo: true, dependencies: {foo: '1.0.0'}, devDependencies: {bar: '1.0.0'}});
//=> { "foo": true, "dependencies": { "foo": "1.0.0" }, "devDependencies": { "bar": "1.0.0" } }
await removePackageDependencies(['foo']);
//=> { "foo": true, "devDependencies": { "bar": "1.0.0" } }
await removePackageDependencies({devDependencies: ['bar']});
//=> { "foo": true }Type: string
Default: process.cwd()
