Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

neko-watch

v0.1.5

Published

Utilities for collecting product data from Japanese marketplaces.

Readme

neko-watch

面向 BOOTH 与 Melonbooks 等日系同人市场的商品信息采集工具,提供统一的 TypeScript 接口与 CLI。

安装

npm install neko-watch
# 或者使用 bun add / pnpm add / yarn add

快速上手:直接使用 getProduct

import { getProduct } from "neko-watch";

const result = await getProduct("https://booth.pm/ja/items/5679925");

console.log(result.marketplace); // "booth" | "melon"
console.log(result.product.name);
  • 脚本会自动解析链接域名并调用对应站点的采集器。
  • 如果需要传入自定义参数,可通过 getProduct(url, { booth: {...}, melon: {...} }) 覆盖默认行为。

仍可单独使用 boothmelon 辅助函数做站点专用抓取:

import { booth, melon } from "neko-watch";

const boothProduct = await booth("https://booth.pm/ja/items/3276669");
const melonProduct = await melon(
  "https://www.melonbooks.co.jp/detail/detail.php?product_id=2344504",
);

CLI 用法

构建后可直接通过 Node CLI 获取商品 JSON:

npm run build
node ./build/index.js https://booth.pm/ja/items/3276669

CLI 会输出与 getProduct 相同结构的 JSON,便于在管道中继续处理。

示例输出
