fix(cmd-api-server): plugins interfere with API server deps hyperledg…
Browse files Browse the repository at this point in the history
…er-cacti#1192

Migrates to the lmify package to install plugins at runtime
instead of doing it via vanilla npm which was causing problems
with conflicting dependency versions where the API server would
want semver 7.x and one of the plugins (through some transient
dependency of the plugin itself) would install semver 5.x which
would then cause the API server to break down at runtime due to
the breaking changes between semver 7 and 5.

The magic sauce is the --prefix option of npm which, when specified
instructs npm to ignore the usual parent directory traversal algorithm
when evaluating/resolving dependency trees and instead just do a full
installation to the specified directory path as dictated by the
--prefix option. This means that we can install each plugin in their
own directory the code being isolated from the API server and also
from other plugins that might also interfere.

Fixes hyperledger-cacti#1192

Depends on hyperledger-cacti#1203
