How to create a custom node in a simple way?

I don’t know the JAVA language but i want to create a custom node like already built node, for instance “Database Row Filter”. I know little bit of JavaScript, so please guide me to how to start?
Video documentation is much preferable.

Hi @simnav,

Do implement “regular” nodes, please take a look at to get started. Since KNIME Analytics Platform is implemented in Java, this is what is required for custom nodes. You can, however, also use our Python integration for implementing custom functionality in your workflows.

If you are looking to create a custom visualization, then take a look at the Generic JavaScript View which let’s you code a visualization with JS.
