WiseMapping Frond End

WiseMapping Frond End is part of the MindMap Open Source Project. The first release of WiseMapping was in 2010 and there was not mayor update on the architecture. In 2021, a major change started with the goal to provide a visual and technology refresh of the project.

WiseMapping Front extracts all the UI related aspects in this repository. You will find three major modules:

• Web2D: Lighway abstraction over SVG for chart renderding.
• Mindplot: Pure vanilla ES6 classes responsible for providing mindmap rendering and edition capabilities.
• Webapp: REACT application that encompass the whole midnmap edition experience.

Getting started

Image Snapshot Testing

We use cypress-image-snapshot for snapshot testing. This is a relatively cheap way of identifying behavior changes based on page screenshots. See visual testing docs for more information.

When a test that contains a matchImageSnapshot call is run, it compares the snapshot to the corresponding one in the snapshots directory. If Any change is detected, the test will fail, and the diff can be found in the cypress/snapshots/*/__diff_output__ folder. If the change is intentional, we should "accept" those changes by updating the snapshot and include it in the commit.

There is a caveat where colors, fonts or ui may differ depending on the host machine running the tests.

A workaround for this is to run the tests using docker. Make sure you have docker and docker-compose installed.

Run snapshot tests: docker-compose -f docker-compose.snapshots.yml up
If anything changed, and the change was intentional, update the snapshots and then commit the new images to source control.
Update snapshots: docker-compose -f docker-compose.snapshots.update.yml up
