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 🙏

NPM Template With TypeScript/TS

介绍

这是一个用于创建一个包含 TypeScript/TS 的 NPM/npm 包的模板。

如何创建一个 TypeScript/TS 的 NPM/npm 包

  1. 在 GitHub 上创建一个仓库,并 clone 到本地

  2. 登录到 npm 官网 https://www.npmjs.com/

注册登录你的账号

  1. 在本地进行登录:使用 npm login 命令

  1. 初始化一个 npm 项目:npm init

其实就是生成一个 package.json 文件: 4. 安装 TypeScript 依赖

npm install --save-dev typescript
  1. 添加 tsconfig.json 文件
{
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "declaration": true,
    "outDir": "./lib",
    "strict": true
  },
  "include": ["src"],
  "exclude": ["node_modules", "**/__tests__/*"]
}

6. 安装 prettiertslint

tslint-config-prettier 用于解决 tslintprettier 之间的规则冲突

npm install --save-dev prettier tslint tslint-config-prettier
  1. 添加 tslint.json 文件
{
  "extends": ["tslint:recommended", "tslint-config-prettier"]
}
  1. 添加 .prettierrc 文件
{
  "printWidth": 80,
  "trailingComma": "all",
  "singleQuote": true
}
  1. package.json 添加需要的运行脚本
  //...
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "build": "tsc",
    "format": "prettier --write \"src/**/*.ts\" \"src/**/*.js\"",
    "lint": "tslint -p tsconfig.json"
  },
  //...
  1. package.json 添加白名单文件
  //...
  "files": ["lib/**/*"]
  //...

只有在 files 数组中的文件才会被 publish 到 npm 上

  1. 安装 jest,用于单元测试
npm install --save-dev jest ts-jest @types/jest
  1. 创建 jestconfig.json
{
  "transform": {
    "^.+\\.(t|j)sx?$": "ts-jest"
  },
  "testRegex": "(/__tests__/.*|(\\.|/)(test|spec))\\.(jsx?|tsx?)$",
  "moduleFileExtensions": ["ts", "tsx", "js", "jsx", "json", "node"]
}
  1. package.json 中旧的 test 运行脚本替换掉
  "scripts": {
    "test": "jest --config jestconfig.json",
    //...
  },
  1. src/ 下创建一个 index.ts 文件
export const Greeter = (name: string) => `Hello ${name}`;
  1. src/ 下创建 __tests__ 文件夹,在src/__tests__ 文件夹下创建一个 test.ts 文件,编写单元测试
import { Greeter } from '../index';

test('My Greeter', () => {
  expect(Greeter('Carl')).toBe('Hello Carl');
});
  1. 运行单元测试
npm run test
  1. package.json 中增加一些前置 or 后置处理脚本
  "scripts": {
    //...
    "prepare": "npm run build",
    "prepublishOnly": "npm test && npm run lint",
    "preversion": "npm run lint",
    "version" : "npm run format && git add -A src",
    "postversion" : "git push && git push --tags"
  },
  • "prepare": "npm run build": prepare 脚本会在项目、发布,还有本地 npm install 之前执行。
  • "prepublishOnly" : "npm test && npm run lint" : prepublishOnly 会在 prepare 脚本之前以及 npm publish运行过程中执行。
  • "preversion": "npm run lint" : preversion 会在发布新的包版本之前执行。
  • "version" : "npm run format && git add -A src" : version 会在新版本被发布之后执行。
  • "postversion" : "git push && git push --tags" : postversion 会在 git 的 commit 创建之后执行。
  1. 完善 package.json 脚本
  "main": "lib/index.js",
  "types": "lib/index.d.ts",
  1. 提交代码
git add -A && git commit -m "Setup Package"
git push
  1. 发布 npm 包
npm publish

如果你是一个包含作用域(Scoped,含有前缀的 @开头的,比如 @vue/compiler-core)的包,并且是公开的,那么需要加上 --access=public,否则会发布失败,因为发布作用域包默认是付费私有。

  1. 升级新版本
npm version patch
  1. 重新发布包
npm publish
