Readme
This allows you to automatically publish a Youtube channel to to a Lemmy community.
Example usage:
async function publishMyFeed() {
try {
return @pdebie.publishYoutubeToLemmy({
instance: "lemm.ee",
auth: @me.secrets.lemmee,
communityId: 23316,
youtubeChannelId: "UChZgikssAJkmiQOv_sO-ngQ",
lastSyncTime: @pdebie.spacexLemmyDb.lastSync,
});
}
finally {
@pdebie.spacexLemmyDb.lastSync = new Date().toISOString();
}
}
Get a Youtube channel ID here.
Make sure to set your lastSync properly, since otherwise you'll keep publishing new posts!
