The same code was working before, My system get formatted, I setup the whole environment again.

$ node -v
v10.9.0
$ npm -v
6.2.0

Sounds like you installed a new version of Loopback than you previously had – see https://loopback.io/doc/en/lb3/Migrating-to-3.0.html#replace-loopback-middleware-getter-properties.

Specifically, changing loopback.compress to require('compression').

I agree with @charlie-s. As of LoopBack 3.0, we no longer ship middleware like compression.
