Sorry I am new to the Joplin community. I have created a new plugin and having trouble finding documentation on publishing a new plugin. My bad if I missed documented steps on this process.
I’m in the same situation as you. My new plugin did not appear in Commits · joplin/plugins · GitHub , even though update script is launched daily.
Plugins updates are pulled from npm registry by script packages/plugin-repo-cli/index.ts via command npm search keywords:joplin-plugin --searchlimit 5000 --json
Web search for joplin-plugin keyword returns 256 results including your plugin. Search from command line returns 250 results only with both your and mine plugin not appearing on result list. Not sure why though.
There seems to be some kind of issue with plugin repo updates yet. It has not received any updates since 2 days ago, despite new plugins being published in npm Registry daily.
