A simple, repository agnostic, API Loader for Typescript

How to Install

Copy, paste and run, like most packages.

npm i @atsu/lilith

Usage

Lilith provides a API to get data in a format that is accessible from your app from different sources.

Currently supported sources are: NHentai and MangaDex, more to come.

This is a basic example on how to use it.

import { useAPILoader } from "@atsu/lilith";

const loader = useAPILoader({
    repo: LilithRepo.MangaDex, // Repository to use
    config: {}, // optional configurations for specific repositories
});

/**
 * Here are some example usages
 */

// We get some search result with some basic book information.
const search: SearchResult = await loader.search("komi");

// We get a book information, like title and chapters
const book: SearchResult = await loader.getBook(
    "a96676e5-8ae2-425e-b549-7f15dd34a6d8",
);

// We get mainly the image URLs from a Chapter
const chapter: Chapter = await loader.getChapter(
    "940f02a3-c4dc-4cc2-9275-5906fcbdb453",
);

Repository specifics

NHentai

NHentai is protected with Cloudflare DDoS protection (Normally is this delay on the initial load while we see the message "Making sure that the connection is secure").

We need to already pass this challenge to start to make requests.

When you, in your browser pass this challenge, you get a cookie appended to your further requests.

The cookie value is on the request headers, and can be seen in your browser by inspecting the page and while using the network tab, you reload, and then check the first request (usually to https://nhentai.net)

It should look like this (example):

cf_clearance=AWJDIseOad1233awgyjADJO41123dwaodHIAWDH-0-1-aab50120.3211.2312faw-100.0.1; csrftoken=awdwDAWDJdpoijPAwdjoaw23DawspojwAWdjoawedaAWDPOKPDWADwad; cf_chl_2=0awdKFWAjpaWD

The important one is cf_clearance, but you can copy all of it.

And also we need the User-Agent, this can be seen with the same method instead of cookie, should be something like this:

Mozilla/1.0 (X41; Linux x86_22; rv:100.0) Gecko/12121214 Firefox/69.0

By knowing this information we NEED to append it in our loader

const loader = useAPILoader({
    repo: LilithRepo.NHentai,
    config: {
        headers: {
            cookie: "... your cookie value",
            ["User-Agent"]: "... your user agent",
        },
    },
});

If you have an invalid, expired or absent headers, you will have code 403 errors on either Lilith or the requests themselves.

MangaDex

Currently getTrendingBooks is not supported on MangaDex, as its API doesn't support it, and also we cannot scrap the website at the moment.
