nyora-java

The Nyora sources SDK for the JVM — the native kotatsu-parsers engine (960+ manga / manhwa / manhua sources) as an in-process library. No HTTP server, no cloud: you call the parsers directly from Java or Kotlin.

This is the JVM sibling of the nyora (Python) and nyora-sdk (JS) clients. Those talk to a helper over REST; on the JVM you don't need to — the engine is JVM code, so this SDK links it straight in.

Requires Java 17+.

Install

Published to GitHub Packages. Add the repo (GitHub Packages Maven requires a token — even for public packages — so supply a PAT with read:packages), plus jitpack for the engine's transitive kotatsu-parsers dependency:

repositories {
    mavenCentral()
    maven("https://jitpack.io")
    maven {
        url = uri("https://maven.pkg.github.com/Nyora-Manga/nyora-java")
        credentials {
            username = providers.gradleProperty("gpr.user").orNull ?: System.getenv("GITHUB_ACTOR")
            password = providers.gradleProperty("gpr.key").orNull ?: System.getenv("GITHUB_TOKEN")
        }
    }
}
dependencies {
    implementation("com.nyora:nyora-java:2.1.0")
}

Maven — same repo + credentials in ~/.m2/settings.xml, then:

<dependency>
  <groupId>com.nyora</groupId>
  <artifactId>nyora-java-jvm</artifactId>
  <version>2.1.0</version>
</dependency>

No-auth alternative — build from source (below): ./gradlew publishToMavenLocal puts com.nyora:nyora-java:2.1.0 in your ~/.m2 for local consumers.

Use (Java)

NyoraSources nyora = NyoraSources.create();

for (MangaSource s : nyora.catalog()) System.out.println(s.getId());

MangaSearchPage page = nyora.popular("parser:MANGADEX", 1);
Manga first = page.getEntries().get(0);

MangaDetails d = nyora.details("parser:MANGADEX", first.getUrl());
List<MangaPage> pages = nyora.pages("parser:MANGADEX", d.getChapters().get(0));

Use (Kotlin)

val nyora = NyoraSources()
val page = nyora.popular("parser:MANGADEX")
val details = nyora.details("parser:MANGADEX", page.entries.first().url)
val pages = nyora.pages("parser:MANGADEX", details.chapters.first())

API

NyoraSources (construct once, reuse — parser services are cached):

Method	Returns
catalog()	every MangaSource the engine can parse
sourceById(id) / findSource(query)	look up a source
popular(id, page=1)	MangaSearchPage
latest(id, page=1)	MangaSearchPage
search(id, query, page=1, filters=[])	MangaSearchPage
details(id, url)	MangaDetails (manga + chapters)
pages(id, chapter)	List<MangaPage>
filters(id)	advertised search filters
supportsLatest(id), imageHeaders(id)	source capabilities

The browse/details/pages calls are blocking (they wrap the engine's coroutine API) — call them off your UI thread.

Source ids are parser:-prefixed, e.g. parser:MANGADEX, parser:MANGAFIRE.

Fat jar

./gradlew sdkJar produces build/libs/nyora-java-<version>-all.jar — the SDK, engine, and all dependencies in one jar. It's also runnable as the standalone Nyora helper server (Main-Class = HelperMain), so the same artifact doubles as nyora-extension-server's engine.

Build

./gradlew publishToMavenLocal   # install to ~/.m2 for local consumers
./gradlew sdkJar                # fat jar

Engine source is the sibling ../nyora-shared checkout (compiled via srcDirs).
