QUESTION
I'm using FastImage to display images in a flatlist in my react native app. Image dimensions are 512 x 512, with about 500kB for each image as size. Images are downloaded from the server and are placed in the flatlist.
I'm testing this with the Allocations instrument of xCode.
When opening the app, I hit about 20mb. But once the images (only 10 images) are loaded, it shoots up to +250mb.
It's weird because those 10 images does not have 250mb in total combined size.
My flatlist looks like this (simplified):

Following these resources 1 and 2, I setup my project with:
a
....buildpacks
file, containing one buildpack to build the site, and the nginx buildpack to serve the generated static HTML files:
ANSWER
Answered 2021-Jan-02 at 19:05Thanks to jonrsharpe comment, I reoriented my searches and found this blog post on heroku engineering blog. Eventually, as stated by jonrsharpe:
The Nginx buildpack won't have Ruby in at all - you need to do any building in the Ruby buildpack context, so all the static buildpack needs to do is serve the results.
Therefore, to launch my middleman build
command, I needed to hook somewhere in the ruby buildpack thing. And in the "jekyll on heroku" link, everything is explained: one should override the assets:precompile
rake task.
- Add
gem "rake"
to my Gemfile (and bundle, of course) - Create a
Rakefile
with theassets:precompile
