- golem15_journal_image_variants (migration 202610280002): a thumbnail
per width of golem15.journal.image_widths (480, 800, 1200 by default,
never wider than the original) and its WebP copy, with the original's
size
- conga job golem15.journal.image_variants (three attempts), queued after
a featured image upload and after an admin save of a post whose images
lack a width; the upload request never encodes
- journal:image-variants [--all] backfills
- featured_images[].variants {width, height, url, webp_url, source_width,
source_height} on the post answers (additive key)

Name: "journal:image-variants",

|
Description: "Write the WebP and resized variants of featured images",
|
|
Long: `Writes, for every post's featured image, a thumbnail at each width of
|
|
golem15.journal.image_widths (480, 800 and 1200 by default) that is not
|
|
wider than the original, and a WebP copy of each next to it, and records
|
|
them in golem15_journal_image_variants. The Journal API lists them as
|
|
featured_images[].variants and the journal layer serves them through
|
|
<picture> with the original format as fallback.
|
|
|
|
New uploads get their variants from the golem15.journal.image_variants job,
|
|
queued after the upload commits. This command is the backfill: without
|
|
--all it takes the images that lack a variant of some width (for example
|
|
after adding a width), with --all it checks every featured image. A
|
|
variant that exists is never written again, so the command can run any
|
|
number of times.`,
