Getting Started with Diagrammable

This project was bootstrapped with Create React App. The main supporting library is MermaidJs which helps provide the rendering of the diagrams from the declared definition. The goal of the application is to provide a standalone implementation of an editor with supportive features, for diagrams used in software development documentation.

The Problem to Solve

Often times when documenting a large software project there can be multiple architecture and detailed design documents, each having its own set of diagrams. The original diagrams are often not available when the time comes to update or edit the document. The developer must then rebuild the diagram from scratch in order to keep the document up to date (e.g. add a new class to a data model). There is also the parallel issue of what tool was used to create the diagram as most developers have their own preferences and toolsets.

The Solution

The solution to these issues lies in using declarative syntax to define the diagrams in a document. This definiation can then be saved as alt text within the document as a property on the image. Therefore when a change is needed later in the life of the document the alt text contains the definition of the diagram. The user can easily copy and paste the definition syntax into Diagrammable and the diagram is rendered and ready to edit. No need to find the original diagram files and/or download and install the original tool.

Supported Diagrams

The large amount of diagrams supported by Diagrammable should make using it for any software document a fairly easy choice. Here is a list of the supported diagrams:

1. Flowchart
2. Sequence Diagram
3. Class Diagram
4. State Diagram
5. Entity Relationship Diagram
6. Use Case Diagram
7. Gant Chart
8. Pie Chart
9. Requirements Diagram

Running Diagrammable

In order to run the application locally you can simply install it from the artifacts (choose correct one for your pc) on the [Releases]() page.

Reviewing or Contributing

If you wish to run from source or develop and contribute to the application you can follow these steps:

1. Install required stack:

   • Node most recent LTS version
   • NPM (installed with Node) or Yarn (installed separately)
   • Text editor of your choice

2. Clone the repository locally:
   git clone git@github.com:elusive/diagrammable.git

3. Open the folder in Visual Studio Code or Neovim or similar in order to view the source tree and the source code organization. The code itself is in the src directory, while the static assets are in the public directory.

4. Run the application in developer mode:

   npm install    # installs the dependencies from NPM
   npm start      # will run app in a browser window <https://localhost:4000>
   # or
   npm run dev        # will run the app in Electron (and open dev tools)

5. Once there are tests to run you can execute the tests using this command: npm run test

Electron Integration

Electron is an instance of the Chromium browser and Nodejs running in a single process. This allows the use of a web app and a server backend (Node) together in the same application, locally on your desktop. The electron window hosts the web application instance and behaves just like a typical software window.

The process of compiling and packaging the application has been somewhat simplified by the use of the NPM scripts (or Yarn). In order to produce the artifacts for installing the application and its Electron host, you can follow these steps:
