mix lightning.adaptors.dump (Lightning v2.19.0)
View SourceWrite this instance's adaptor catalogue to a JSON file, in the shape
Lightning.Adaptors.Catalogue.upsert_adaptor/1 accepts and
mix lightning.adaptors.import reads back.
This is how adaptors get mirrored into an airgapped environment. Hydrate
an online instance as usual, dump it here, carry the file across, and
import it on the offline instance. mix lightning.adaptors.snapshot
produces the same kind of file by fetching npm directly, for when there
is no populated catalogue to dump from.
Usage
mix lightning.adaptors.dump --path snapshot.json
mix lightning.adaptors.dump --path snapshot.json --source local--source defaults to npm.
Icon bytes themselves live in the on-disk icon cache, not the catalogue,
so they don't travel in this file. It carries the icon metadata
(extension, sha256, etag) so an imported row can serve an icon already
present at ADAPTORS_ICONS_PATH on the target instance instead of
refetching from GitHub. Copy that directory across alongside this file.
