frank-config-layout

Layout algorithm for Frank configs / flows. WeAreFrank! wishes to use a custom layout algorithm that should look better than images produced by Mermaid. This project assumes that the Frank!Framework can convert Frank configurations or adapters (XML code) to Mermaid commands. See Mermaid example for the syntax of Mermaid files. This project reads Mermaid text and displays it using a custom algorithm.

The algorithm has not been finished yet. In its current state, the produced drawing does not look like intended. There is a user interface that allows humans to improve the layout. This way, the developers can investigate how to improve the algorithm. A future release of this project should eliminate the need for human intervention.

Development environment and usage

To use this project, please do the following:

• Clone this project with git clone.
• Install package manager yarn. Presently we use version 1.22.21.
• Execute yarn install --immutable.
• Run the Karma tests with yarn ng test.
• Run the project with yarn ng serve.
• Open a webbrowser and go to http://localhost:4200/.
• In the top-left corner enter some Mermaid text. Here is a simple example.
• Press "Load with longest path algorithm". See figure below.
• Try the controls to change the drawing.

Publishing

This project is published on npmjs. We publish a service that can produce a static SVG from Mermaid commands. Do the following to publish the next version on npmjs:

• Ensure that the checkout directory does not contain folder dist.
• Ensure that all development work has been committed.
• Run yarn install --immutable.
• Ensure that your development work has been tested.
• If you fixed things, commit your work.
• Run yarn packagr. This should produce folder dist within the checkout directory.
• Change directory to dist. Then do yarn pack.
• Publish using yarn publish.
• Run git tag vX.Y.Z with X.Y.Z the version you just published
• Run git push vX.Y.Z.
• Update the version number in package.json for the next release cycle. Commit and push that.
