@sebastián-cisneros In static:api.routes, you'll want to call controllerHelpers.setupAPIRoute to mount the route to the appropriate /api/v3/plugins mount point.
You can see an example of how we do it in the quickstart plugin
It has been about a year since I develop a nodebb plugin. I would like to get into plugin development again to add a few features to my makerspace community forum. I know that plugin APIs must have changed a bit since then. Is the developer documentation the best place to start looking to get up to date information about the latest patterns and API's we can use? Are there any other resources I should look at that would help me get up to speed again?
