What is this?
The LINE store search excludes certain results, specifically when they are region locked, or have a time limit. However, the metadata can always be requested for a sticker, unless it has been deleted. So this website scrapes the LINE store for every sticker's metadata and saves it onto a local sqlite DB.
While all the metadata might be downloaded beforehand, the stickers themselves are downloaded on demand. Stickers with animation or sound will take longer, since they must be merged into a webm file. So if you are the first person to request a sticker, you might have to wait a bit. I also don't leave the scraper running at all times, only running it from time to time, so new stickers might be missing.
If you want to run it yourself you can get the code at: https://git.waka.moe/zagh/web-line
Technical Information
Here are the URLs used in the scraping and downloading.
METADATA_URL = https://stickershop.line-scdn.net/stickershop/v1/product/{id}/iphone/productInfo.meta
ZIP_URL = https://stickershop.line-scdn.net/stickershop/v1/product/{id}/{platform}/{type}{suffix}.zip
Below you can see the explanation as to what each variable is.
id = 12345 (id of the sticker)
platform = android/iphone (iphone requires suffix)
type = stickers/stickerpack (stickers - normal, stickerpack - with audio or animation)
suffix = @2x (@2x - iphone)
Sticker metadata is downloaded from METADATA_URL and saved onto a database. The metadata allows us to choose the correct type.
Sticker data is downloaded from ZIP_URL and saved onto the disk. Depending on the type the files may be merged into a webm using ffmpeg.
The difference between android and iphone is the resolution. The iphone stickers have double the resolution as indicated by the suffix @2x.
