Schematics Utilities

npm Package Version License code style: prettier docs: typedoc

At the moment, none of the utilities from the Angular Schematics package are exported.

This project was created from that purpose - providing a collection of general and useful utilities for Schematics, based on non-exported existing utilities and further.

You might use this project as a polyfill until these utilities will be exported officially by the relevant teams (and then just replace the path you import). However, consider sticking with this project for additional and unique utilities which are planned for the future.

How to Install

To Install using npm, simply do:

npm install schematics-utilities

How to Use

import { Rule, Tree } from '@angular-devkit/schematics';
// 1. Import the needed utilities
import { addPackageJsonDependency, NodeDependency, NodeDependencyType } from 'schematics-utilities';

function addDependencies(host: Tree): Tree {
  const dependencies: NodeDependency[] = [
    { type: NodeDependencyType.Default, version: '4.17.10', name: 'lodash-es' }

  // 2. Just use it whenever you need :)
  dependencies.forEach(dependency => addPackageJsonDependency(host, dependency));

  return host;

export default function(): Rule {
  return (tree: Tree) => {

    return tree;
