Code

Do not change the name of the class. It must be Provider.

/// <reference path="./manga-provider.d.ts" />
 
class Provider {
    private api = "https://example.com"
		
    getSettings(): Settings {
        return {
            supportsMultiLanguage: false,
            supportsMultiScanlator: false,
        }
    }

    // Returns the search results based on the query.
    async search(opts: QueryOptions): Promise<SearchResult[]> {

            image: "https://example.com/image.jpg",
        }]
    }
    
    // Returns the chapters based on the manga ID.
    // The chapters should be sorted in ascending order (0, 1, ...).
    async findChapters(mangaId: string): Promise<ChapterDetails[]> {

            id: `999-chapter-1`,
            url: "https://example.com/manga/999-chapter-1",
            title: "Chapter 1",
            chapter: "1",
            index: 0,
        }]

	// TODO
        return [{
            url: "https://example.com/manga/999-chapter-1/page-1.jpg",
            index: 0,
            headers: {
                "Referer": "https://example.com/manga/999/chapter-1",

        }]
    }
}

Workflow

search is called twice when the user opens the manga page. Each time with a different manga title as query (English, Romaji).

The best match will automatically be selected and findChapters will be called with the manga ID from the search result to get the list of chapters.

findChapterPages is called when the user requests to read or download the chapter.

Manga ID, Chapter ID

Depending on the source website you’re getting the data from, the URLs might get a little complex.

For example, if a manga’s chapter page is: consisting of 2 URL sections (in this case, the manga ID and the chapter ID), you can construct the Seanime chapter ID by combining the two parts and splitting them in findChapterPages .

Settings

If your manga source supports multiple languages for chapters and you want your extension to give this option to the users, set supportsMultiLanguage to true and set the language property for each of the ChapterDetails. Preferably .
Similarly, you can also give the option to choose a scanlator by setting supportsMultiScanlator to true and setting the scanlator property for each of the ChapterDetails.
