gml v0.1.6

graphml-schema-generator

A tool to generate TypeScript interfaces from graphml graphical files. This tool has a very specific use-case. While it's not for everyone, I believe it to be easy enough to modify to suit similar needs.

Usage

(Make sure you read the use-case and caveats sections below!)

Global Install

npm install -g graphml-schema-generator

Local Install

npm install --save graphm-schema-generator

If you don't want to pollute your development environment this might be a better way to install this. Then you can use npm scripts to alias it to a more manageable command.

Use case

The generator is intended to transform a graphml file generated by tools such as yWork Yed.

For instance the following entity defined graphically using yEd translate to the typescript code just underneath it.

import { ObjectID } from 'mongodb';

interface User {
    _id?: ObjectID;
    username: string;
    password: string;
    email: string;
}

This code will be saved into the directory of your choosing with this naming convention: entities.interface.ts. The interface name itself will be the singular version of entities.

Like I said, this is very specific, but the whole goal of this was to avoid the arduous task of having to do the work twice. This way, the whole schema can be defined inside a tool such as yEd and the interfaces are generated automatically.

Caveats

There are a few things to take into consideration before using this module.

• Only works with yEd and TypeScript. Should there be any type of interest in this, I don't mind expanding the scope, but I first developed this for my own use and it suits them just fine.
• Inside of yEd, you need to use the first type of node inside of "Entity Relationship" category. This is because this node allows for two labels (one for the entity name, and one for the parameters).

TODO:

• Generalize usage to more graphml tools
• Complete readme file
• Provide examples to the usage section
