# This is a multistage Dockerfile.

# In the first stage we install system build dependencies, copy project files and build them
|
|
# In the second stage, we start fresh and only copy necessary files. We also purge node_modules devDependencies.

#### Build stage ####

# Only copy node dependency information and install all dependencies first
|
|
