Publish Package JSON Generator

Generate a dedicated package.json for publishing without development bloat.

• Only include properties you need for publishing
• Override development values
• Addition of new properties

Quick Start

• Install the ppjg as a development dependency

node i -D ppjg

• Create a new publish config called ppj.config.js in your project root directory
• Define which package.json keys to persist and which to override:

module.exports = {
  persist: ['author', 'dependencies'],
  alter: {
    version: process.env.VERSION
  }
};

• Run ppjg by executing the generatePublishPackageJson function or by executing the binary via Node

VERSION='V1' npx ppjg

• Generated example ./out/package.json

{
  "author": "John Doe",
  "dependencies": {
    "example": "1.0.0"
  },
  "version": "V1"
}

Configuration

The Publish-Configuration

The publish-configuration defines which properties of the projects package.json are kept and which will be overwritten. By default, the publish-configuration is defined inside the ppj.config.js. To provide a differently named configuration, see the Generator Configuration section.

Property	Description	Config Property
persist	An array of property names which will be kept inside the publish-configuration	{ persist: ['author', 'name'] }
alter	An object of new or altered properties and their values	{ alter: { bin: './cli.js' } }

The Generator Configuration

Property	Description	CLI Flag	Config Property
Output Directory	Defines the location of the generated package.json	-o, --outDir DIRECTORY	{ outDir: DIRECTORY }
Publish Config File	File name of the config used for the generation	-c, --config FILE	{publishConfigFileName: FILE}

Usage

Binary

The provided binary offers easy invocation via the CLI or NPM script.

CLI

• Directly execute the binary with npx:

npx ppjg [options]

NPM script

• Create a new script entry invoking the binary:

{
  "scripts": {
    "generatePPJ": "ppjg [options]"
  }
}

• Run the script:

npm run generatePPJ

Programmatically

• It is also possible to invoke the generator function directly:

import { generatePublishPackageJson, GeneratorConfigModel } from 'ppjg';

const config: Partial<GeneratorConfigModel> | undefined = { /* optional config data */ }

generatePublishPackageJson(config);
