# Check if we need to copy node_modules.

# The reasoning for a (mostly) read-only node_modules folder:
|
||
# ideally we’d symlink the folder directly to the Nix store
|
||
# so that we’re guaranteed to have a reproducible source.
|
||
# Unfortunately react-native wants to build some stuff after the fact
|
||
# and this is incompatible with the concept of a pure Nix package.
|
||
# Therefore we copy the whole source to the repo directory,
|
||
# allow writing only on the folders where it is absolutely required,
|
||
# and therefore we still keep some peace of mind that the rest
|
||
# of node_modules is unchanged the rest of the time.
