@proscom/typeorm-uml 1.2.0

A command line tool to generate UML diagrams for Typeorm projects. It uses plantuml to render diagrams and outputs an URL to a diagram. It can also output diagram definition in the plnatuml syntax.

This is a fork of https://github.com/eugene-manuilov/typeorm-uml with couple of additional features:

  • output plantuml syntax instead of the url
  • output entity/property or table/column names or both
  • use regexp in include/exclude


Install this command as a development dependency to your project:

npm i -D @proscom/typeorm-uml
// or
yarn add --dev @proscom/typeorm-uml


Add a new script to your package.json to be able to run it:

    "name": "myproject",
    "scripts": {
        "db:diagram": "typeorm-uml ormconfig.json"

Then run npm run db:diagram and you will receive an URL to an image with your diagram. You can use this URL to add to your README file or you can download the image and add it to your repository.


  $ typeorm-uml [CONFIGNAME]

  CONFIGNAME  [default: ormconfig.json] Path to the Typeorm config file.

  -c, --connection=connection  [default: default] The connection name.
  -d, --download=download      The filename where to download the diagram.
  -e, --exclude=exclude        Comma-separated list of entities to exclude from the diagram.
  -f, --format=png|svg|txt     [default: png] The diagram file format.
  -i, --include=include        Comma-separated list of entities to include into the diagram.
  --uml                        Outputs plantuml syntax instead of the url
  --monochrome                 Whether or not to use monochrome colors.


If you use .ts entities in your Typeorm config, then run this command with ts-node like this:

ts-node ./node_modules/@proscom/typeorm-uml/bin/run ormconfig.json



typeorm-uml --format=svg --monochrome
