NGD: Angular Dependencies Graph

A tool that allows you to view your Angular application dependencies.

Generated Graphs (sample)

Sample Application

Angular Material 2

ng-bootstrap

soundcloud-ngrx

Install

Install from npm:

npm install -g @compodoc/ngd-cli

Install from Yarn:

yarn global add @compodoc/ngd-cli

Usage the CLI

$ ngd --help

Usage: ngd [options]

Options:

  -h, --help                    Output usage information
  -V, --version                 Output the version number
  -f, --file [file]             Entry *.ts file
  -p, --tsconfig [config]       A tsconfig.json
  -l, --files [list]            A list of *.ts files
  -g, --display-legend          Display the legend in the generated graph (default: true)
  -s, --silent                  In silent mode, log messages aren't logged in the console
  -t, --output-formats [formats] Output formats (default: html,svg,dot,json)
  -d, --output [folder]         Where to store the generated files

1) use a tsconfig.json:

Run inside your project (where your tsconfig.json is located):

$ cd my-awesome-cli-angular-app/
$ ngd
$ # or
$ ngd -p ./tsconfig.json

Note: This will read the files entry point in your tsconfig.json and crawl your app. If the entry point is not found, all *.ts files will be crawled, but not those mentioned in the exclude property (more details).

2) provide an entry file:

$ cd my-awesome-cli-angular-app/
$ ngd -f src/main.ts

NOTE: The file you provide should contain your root component.

Usage the API

1. Import the DotEngine and Compiler from @compodoc/ngd-transformer and @compodoc/ngd-compiler:

import { DotEngine } from '@compodoc/ngd-transformer';
import { Compiler } from '@compodoc/ngd-compiler';

2. Create an instance of a compiler:

const compiler = new Compiler(files, {
    tsconfigDirectory: cwd
  }
);

3. Get the found dependencies:

const deps = compiler.getDependencies();

4. Pass those dependencies to the transformer:

const engine = new DotEngine({
  output: program.output,
  displayLegend: program.displayLegend,
  outputFormats: program.outputFormats.split(',')
});

5. Generate the graph:

engine.generateGraph(deps).then(file => { ... });
