Docs

Read the docs on GitHub pages.

Example

Import

CommonJS

const { API, TagTypes, } = require('nhentai-api');

ES6

import { API, TagTypes, } from 'nhentai-api';

Use

Initialize API client

const api = new API();

Get the book

api.getBook(177013).then(book => {
	api.getImageURL(book.cover);    // https://t.nhentai.net/galleries/987560/cover.jpg
	api.getImageURL(book.pages[1]); // https://i.nhentai.net/galleries/987560/2.jpg
});

Search for the books

api.search('test').then(async search => {
	console.log(search); /*
	Search {
		api: API { hosts: [Object], ssl: true, agent: [Agent] },
		query: 'test',
		page: 1,
		perPage: 25,
		books: [
			[Book], [Book], [Book], [Book],
			[Book], [Book], [Book], [Book],
			[Book], [Book], [Book], [Book],
			[Book], [Book], [Book], [Book],
			[Book], [Book], [Book], [Book],
			[Book], [Book], [Book], [Book],
			[Book]
		],
		pages: 67
	} */
	search = await search.getNextPage(); // Same as api.search('text', 2);
	console.log(search); /*
	Search {
		// Same as above
		page: 2,
		// Same as above
		books: [
			// Books from 2nd page of search
		],
		// Same as above
	} */
});

In case you need to change API implementation (e.g. change proxy) you can pass api to

search.getNextPage(api);

You can also use async generator:

// Get first 2 pages
for await (const search of api.searchGenerator('test')) {
	console.log(search);
	if (search.page >= 2)
		break;
}

Working with tags

book.tags has type of TagsArray, it is just an Array<Tag> with helper methods.

const tag = book.tags[0]; // Tag

Get tag id

tag.id;

Get tag name (without count)

tag.name;
// or
tag.toString();

Get tag name (with count)

tag.toString(true);

Get tag type (as string)

tag.type.type;
// or
tag.type.toString();

Pre-filtered tags

book.pureTags;   // pure tags (with type 'tag')
book.categories; // category tags
book.artists;    // artist tags
book.parodies;   // parody tags
book.characters; // character tags
book.groups;     // group tags
book.languages;  // language tags

Filter tags

Get artists:

book.artists;
// or
book.getTagsWith({
	type: TagTypes.Artist, // you may also use Tag.types.Artist or Tag.types.get('artist') 
}); // TagsArray (subclass of Array<Tag>)
// or
book.getTagsWith({ type: 'artist', }); // TagsArray (subclass of Array<Tag>)

Get tag with name english:

book.getTagsWith({ name: 'english', }); // TagsArray (subclass of Array<Tag>)

Get categories

book.categories;
// or
book.getTagsWith({ type: TagTypes.Category, }); // Recommended
// or
book.getTagsWith({ type: Tag.types.Category, });
// or
book.getTagsWith({ type: Tag.types.get('category'), });
// or
book.getTagsWith({ type: 'category', });

Get tags comma separated

Without counts:

book.tags.toNames().join(', ');
// or
book.tags.join(', ');

With counts:

book.tags.toNames(true).join(', ');
// or
book.tags.map(tag => tag.toString(true)).join(', ')

Get all artists:

// With counts
book.artists.toNames(true).join(', ');
// or
book.getTagsWith({ type: TagTypes.Artist, }).toNames(true).join(', ');
// Without counts
book.artists.join(', ');
// or
book.artists.toNames().join(', ');
// or
book.getTagsWith({ type: TagTypes.Artist, }).join(', ');
