Finally got this to work! It seems that the nodemailer plugin has a dependency on node v 6.0.0. As soon as I changed the dependency to a compatible version the problem was solved.
Hope this helps someone else facing the same issue.
I was trying to install a nodebb email plugin to send email via a third party service like SES. So I tried out the emailer-local plugin. But it seems that it is not compatible with V1.4.5. Here is the error log that I get when I activate this plugin:-
at Object.Plugins.requireLibrary (/home/bhavya/forum/nodebb/src/plugins.js:40:33) 18/4 14:22:15  - warn: [plugins] Unable to parse library for: nodebb-plugin-emailer-local 18/4 14:22:15  - warn: [plugins/load] The following plugins may not be compatible with your version of NodeBB. This may cause unintended behaviour or crashing. In the event of an unresponsive NodeBB caused by this plugin, run `./nodebb reset -p PLUGINNAME` to disable it. * nodebb-plugin-emailer-local
What is recommended email plugin for nodebb that works for nodebb 1.4.5?
@scottalanmiller Thanks for the info! Could you share your server specs? Has anything changed for you in these 2 years? I'm planning to use the same setup as yours. Mongodb , no redis, couple of forums running on the same server.
Also do users of mangolassi like the chat feature or do they just stick to normal forums?
Unfortunately I could not find a way to page the feed so if you have more than a 100 posts this probably wont work.
