Mosca takes ages to install on alpine linux #584

Closed nite closed 7 years ago

nite commented 7 years ago

Not sure if this is the right place for this - but mosca takes over 5 mins to npm install on alpine linux - seemingly as no binaries for zmq, kerberos, leveldb, snappy etc - an excerpt from the logs below.

npm WARN deprecated mongodb@2.1.21: Please use 2.2.16 or higher due to a regression in updateOne/Many upsertedId return value
npm WARN deprecated node-uuid@1.4.7: use uuid module instead

You are using ARM on a probably "slow" CPU for embedded applications.

The current architecture of Mosca is monolithic, and there is not much you can do. However, you can use https://github.com/mcollina/aedes, which is smaller and has all the features as separate modules.
