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 🙏

v0.1.0

Published

Box2D TypeScript declarations for LayaAir 2D physics

Readme

box2d-laya-dts

为 LayaAir 2D 物理 API 提供 Box2D 2.4 风格的类型声明,不修改 Laya 官方的 LayaAir.d.ts。

安装

npm install box2d-laya-dts

在 TypeScript 项目中引用声明:

import "box2d-laya-dts"; // 副作用导入,只加载全局类型

function inspectBody(body: box2d.b2Body) {
  const position = body.GetPosition();
  const velocity = body.GetLinearVelocity();
  return { x: position.x, y: position.y, speedX: velocity.x };
}

也可以用三斜杠指令(不会产生运行时导入):

/// <reference types="box2d-laya-dts" />
// 或
/// <reference types="box2d-laya-dts/box2d" />

或在 tsconfig.json 中通过 compilerOptions.types 引入:

{
  "compilerOptions": {
    "types": ["box2d-laya-dts"]
  }
}

以上几种方式(bundler / node16 / node10 模块解析)均已验证可用。

包同时提供 box2d.* 命名空间和 Box2DWeb 常见的 Box2D.* 类型别名。

本地开发

npm install
npm run build

发布前可用以下命令检查 npm 包内容:

npm pack --dry-run
