What are the TypeScript type definitions for the "package.json" configuration file?

Question

What are the TypeScript type definitions for the "package.json" configuration file?

What is the most efficient method for typing the content of the "package.json" file in TypeScript?

import { promises as fs } from 'fs';

export function loadManifest(): Promise<any> {

  const manifestPath = `${PROJECT_DIR}/package.json`;

  return fs.readFile(manifestPath, { encoding: 'utf-8' });

}

In the code snippet above, I am currently using Promise<any> as the return type. However, I am curious if there are any alternative approaches or packages available that I may not be aware of.

DefinitelyTyped has addressed the issue in question here. The latest update on the matter directs users to @schemastore/package, where the correct type definitions can be found.

Upon successful installation of the package, you can utilize it as shown below:

import { promises as fs } from 'fs';
import {JSONSchemaForNPMPackageJsonFiles} from '@schemastore/package';

export function loadManifest(): Promise<JSONSchemaForNPMPackageJsonFiles> {
  const manifestPath = `${PROJECT_DIR}/package.json`;
  return fs.readFile(manifestPath, { encoding: 'utf-8' }) as Promise<any>;

}
