mangadex-desktop-api2

Rust

mangadex-desktop-api2 is a library for downloading and managing titles, covers, and chapters from MangaDex.

This is built on top of the mangadex-api. But unlike the SDK, it allows you to download, read, update and delete chapter images, covers and titles metadata from your local device.

It might also get a package management system, sees #174

If you're building a MangaDex desktop app (like Special Eureka) or a private downloading service, this library provide a bunch of features that might help you:

  • Configurable download directory: With the DirsOptions, you can change the

  • It's asynchronous: This library is built on top of actix actors (not actix-web) but it requires you to use actix system handler as an asynchronous runtime.

    Here is an example of using actix with tauri:

      #[actix::main]
      async fn main() {
          // Since [`actix`] is built on top of [`tokio`], we can use [`tokio::runtime::Handle::current()`]
          // to share the actix runtime with Tauri
          tauri::async_runtime::set(tokio::runtime::Handle::current());
    
          // bootstrap the tauri app...
          // tauri::Builder::default().run().unwrap();
      }
    

Feature flags

None for now!

Some concepts that you need to know

This library now uses Actor model to track the download process in real-time.

Each downloading task: chapter / cover images downloading and title metadata is an actor and which I call Task. You can listen to a task to know it's state like if it's pending, loading, success, or error. Each task have an unique id, corresponding to what it's downloading. Downloading a manga will spawn a MangaDownloadTask actor, cover will spawn a CoverDownloadTask, etc...

A Task is managed by a manager corresponding by the task type, which means that there is a ChapterDownloadManager, a CoverDownloadManager and a MangaDownloadManager.

To manage all of this there is a top level DownloadManger that allows you to interact with the manager. But it also contain an inner state allows to interact with the underlying MangaDex API Client, DirOptions API and the download history actor.

DirOptions API

The DirOptions API manages every interaction to the filesystem. You can get, create/update data and delete data like metadatas and images.

Getting data

To get data, it is done with the DataPulls.

    use actix::prelude::*;
    use mangadex_api_types_rust::{MangaSortOrder, OrderDirection};
    /// Yes! we have a prelude module too.
    use mangadex_desktop_api2::prelude::*;

    fn main() -> anyhow::Result<()> {
        /// start a actix system
        let run = System::new();
        /// Runs your async code with `.block_on`
        run.block_on(async {
            /// Init the dir option api
            let options = DirsOptions::new_from_data_dir("data");
            /// Verify and init the required directories.
            /// This is mostly not required because `.start()` automatically call `.verify_and_init()`
            options.verify_and_init()?;
            /// init the actor
            let options_actor = options.start();
            /// init a data pull
            let data_pull = options_actor
                .get_manga_list()
                .await?
                /// Yes, you can sort data now
                .to_sorted(MangaSortOrder::Year(OrderDirection::Ascending))
                .await;
            /// Iterate over the results
            for manga in data_pull {
                println!("{:#?} - {has_failed}", manga.id);
                if let Some(year) = manga.attributes.year {
                    println!("year {year}",)
                }
            }
            Ok::<(), anyhow::Error>(())
        })?;
        Ok(())
    }

Create/update data (aka push)

To push data, it is done with the Push trait.

    use std::collections::HashMap;

    /// This example will illustrate how to push data to a
    /// You need to enable the `macros` feature for `actix` to make this example work.

Deleting data

To delete data, it is done with the Delete traits.

    use std::str::FromStr;

    use actix::prelude::*;
    use mangadex_desktop_api2::prelude::*;
    use tokio_stream::StreamExt;
    use uuid::Uuid;

    fn main() -> anyhow::Result<()> {
        // Init the actix system runner
        let run = System::new();
        run.block_on(async {
            // Start the option actor
            let options_actor = DirsOptions::new_from_data_dir("data").start();
            let manga_id = Uuid::from_str("b4c93297-b32f-4f90-b619-55456a38b0aa")?;
            // You can just call `.delete_manga(Uuid)` to delete a give manga
            let data = options_actor.delete_manga(manga_id).await?;
            // The `MangaDeleteData` consists of `covers` field which is the deleted covers ids
            // and `chapters` field which is the deleted chapters ids
            println!("{:#?}", data);
            // Get all the manga chapter
            let chapters: Vec<Uuid> = {
                let params = ChapterListDataPullFilterParams {
                    manga_id: Some(manga_id),
                    ..Default::default()
                };
                options_actor
                    .get_chapters()
                    .await?
                    .to_filtered(params)
                    .map(|o| o.id)
                    .collect()
                    .await

                    ..Default::default()
                };
                options_actor
                    .get_covers()
                    .await?
                    .to_filtered(params)
                    .map(|o| o.id)
                    .collect()
                    .await
            };
            // check if there is no chapters left
            assert!(chapters.is_empty(), "Some chapter still remains");
            // check if there is no covers left
            assert!(covers.is_empty(), "Some covers still remains");
            Ok::<(), anyhow::Error>(())
        })?;
        Ok(())
    }

The DownloadHistory API

Only purpose of the DownloadHistory API is to track download errors. Which means that if you have an unfinished download or an failed download, you should be able to see it. You can interact with it with the HistoryActorService, but be careful when inserting or removing entries. It could pontentialy break your app.

Since v1, this package has now an MIT licence, so it's your choice :).
