Tranga v2

Automatic Manga and Metadata downloader

About The Project

Tranga can download Chapters and Metadata from "Scanlation" sites such as

• MangaDex.org (Multilingual)
• MangaWorld (it)
• AsuraComic (en) thanks @yacob841
• WeebCentral (en) thanks @TheyCallMeTravis
• ❓ Open an issue

and trigger a library-scan with Komga and Kavita.
Notifications can be sent to your devices using Gotify, LunaSea or Ntfy, or any other service that can use REST Webhooks.

What this program does and does not do

DOES: Download Images from a Website.
DOES: Create Archives with those images.

how?

Tranga (this repository) is a REST-API and worker in one. Tranga provides REST-Endpoints to configure workers (Jobs). Requests include searches for Manga, creating and starting Jobs such as downloading available chapters. For available endpoints check http(s)://<hostedInstance>/swagger or API/openapi/API_v2.json

This repository does not include a frontend. A frontend can take many forms, such as a website:

tranga-website (Original, if you use the docker-compose.yaml in this repo it will spin up an instance for this)

tranga-yacobGUI (Third Party)

When downloading a chapter (meaning the images that make-up the manga) from a Website, Tranga will additionally try and fetch Metadata from the same website or enhance it from third-party sources. Downloaded images can be jpeg-compressed and/or made black and white to save on diskspace (measured at least a 50% reduction in size, without a significant loss of quality).

Tranga will then package the contents of each chapter in a .cbz-archive and place it in a common folder per Manga. If specified, Tranga will then notify library-Managers such as Komga and Kavita to trigger a scan for new chapters. Tranga can also send notifications to your devices via third-party services such as Gotify, Ntfy, or any other REST Webhook.

Screenshots

This repository has no frontend, however checkout tranga-website for a default!

Inspiration:

Because Kaizoku was relying on mangal and mangal hasn't received bugfixes for its issues with Titles not showing up, or throwing errors because of illegal characters, there were no alternatives for automatic downloads. However, Kaizoku certainly had a great Web-UI.

That is why I wanted to create my own project, in a language I understand, and that I am able to maintain myself.

Getting Started

Docker

Built for AMD64. Also available for ARM64 and ARMv7 if it feels like it (dependencies aren't always your friend).

An example docker-compose.yaml is provided. Mount /Manga to wherever you want your chapters (.cbz-Archives) downloaded (where Komga/Kavita can access them for example).
The file also includes tranga-website as frontend. For its configuration refer to the Tranga-Website Repository README.

Bare-Metal

While not intended, if your machine can run .NET (and is AMD64, ARM64, ARMv7), it can run Tranga without docker.

Configuration-Files are stored at

• Linux /usr/share/tranga-api
• Windows %appdata%/tranga-api

Downloads (default) are stored in (see DOWNLOAD_LOCATION)

• Linux /Manga
• Windows %currentDirectory%/Downloads
