NHentai Konnichiwa
A simple usercript for downloading galleries from NHentai and mirrors
Description
Userscript to download galleries from NHentai. It has features to be used with
konnichiwa. NHentai started using
Cloudflare protection and now you can't reliably download hentai with the
download tab in konnichiwa. To make things easier for yourself if you use
konnichiwa, you could use this userscript.
If you don't use konnichiwa, you can still use this without losing any
functionality.
Supports only
Tampermonkey
and
Violentmonkey.
Mirror sites can still break because of CloudFlare
Features
Checkboxes at the top left corner of every gallery on any page
On the individual gallery page.
On the homepage, search and similar pages.
On the recommendations section.
Buttons at the bottom-left corner of the page
Download button: Download all selected galleries. The Download button changes state depending on the stage of download.
If the data is being fetched, it looks like this:
If the data is being downloaded, it looks like this:
Config button: Change configuration options.
Check-all checkbox: Select all galleries on the page. Since there are
checkboxes on the recommendation ("More like this"), if you check this on a
gallery page, it's recommendations will get selected as well.
Configuration options
Domain to Use: Domain to be used for fetching images. There are three
available options:
- NET (from nhentai.net)
default
- COM (from nhentai.com)
nhentai.net image download is quite slow. Using nhentai.com makes quite a big
difference in download time. The tradeoff is the extra fetching time. If
you want the fetching time to be shorter and downloads to fail less
often, use NET. If you want faster download speeds and can bear with failed
downloads and longer fetching times, use COM.
If an image/gallery does not exist on nhentai.com, nhentai.net is used as a
fallback.
On mirror sites, if the NET option is set, their own image links will be used
instead of nhentai.net.
Download batch size: Number of downloads to run simultaneously.
Default is 10. If you make it too high, a lot of downloads will fail.
Title format: The galleries are downloaded in their own separate
directories. This option is for specifying the name of those directories.
There are four available options:
- pretty
default
- english
- japanese
- id
Filename to prepend: The text that gets added before every filename. If no
value is specified, The default filename is {page}.{ext}.
Filename separator: The character to put between given filename (if any)
and {page}. So, if this value is set to Underscore and the filename is
set to myFileName, the files will be saved as myFileName_{page}.{ext}.The
symbols /, \ and | will also be replaced by this separator.
There are three available options:
- Space
default
- Hyphen
- Underscore
Save JSON: This is mainly for use with konnichiwa. This outputs a file in
the format specified
here.
There are three available options:
- Don't save
default
- Save as JSON file
- Copy to clipboard
Save as JSON file will save the content to a file named with the number of
milliseconds since January 1, 1970. You can then run refresh_db.php from
konnichiwa on this file to add all the downloaded galleries to your database.
Include groups in authors: If the Save JSON option is set, the output
has a key authors. This decides if the Groups in NHentai will be added to
its value.
Button orientation: The three buttons (download, config and check-all) are
by default aligned vertically. But if you want you can change this. There are
two available options:
- Vertical
default
- Horizontal
Clear and stop downloads: This probably needs a little explanation. The
downloads are stored in the extension storage. Sometimes, if you reload a tab
in between downloads, some files are not removed from the storage and the
script tries to download them everytime a new tab in compatible sites is
opened. You might need to click this if that happens. It's rare though.
Suggestions
While there are measures to continue downloads even after page
switches/reloads, it is suggested to stay on the same page while a download
is ongoing.
