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 🙏

rollup-plugin-inject-dotenv

v0.0.3-beta

Published

parse env file config and inject to workspace.

Readme

rollup-plugin-inject-dotenv 使用说明

基于rollup实现本地.env环境变量文件的注入, 支持.env.development和.env.production文件, 同时支持输出类型定义文件。

安装

npm install --save-dev rollup-plugin-inject-dotenv

支持配置

  • dto (string) - 输出的类型定义文件路径,默认值为typings/env.d.ts
  • mode (string) - 环境模式,developmentproduction,对应读取.env.development.env.production文件,不设置的时候会默认从process.env.NODE_ENV获取,不设置从.env文件读取
  • path (string) - 环境变量文件路径,若设置path,则会读取该文件,否则会通过mode配置获取文件地址
  • env (object) - 环境变量对象,若设置env,则会将其注入到process.env对象中,优先级高于.env文件

使用

// rollup.config.js
import injectEnv from 'rollup-plugin-inject-dotenv';

export default {
  input: 'index.js',
  output: {
    file: 'dist/bundle.js',
    format: 'cjs'
  },
  plugins: [    
    injectEnv({
        dto: 'typings/env.d.ts', // 输出的类型定义文件路径
        mode: 'development' // 环境模式,development或production,对应读取.env.development或.env.production文件, 不设置的时候会默认从process.env.NODE_ENV获取,不设置从.env文件读取
        path: '.env' // 环境变量文件路径,若设置path,则会读取该文件,否则会通过mode配置获取文件地址
        env: { // 环境变量对象,若设置env,则会将其注入到process.env对象中,优先级高于.env文件
            NODE_ENV: 'development',
            API_URL: 'https://example.com'
        }
    }),
    // other plugins
  ]
};

注意事项

  • .env文件不存在,则不会注入任何环境变量
  • 需保证rollup-plugin-inject-dotenv 插件在解析前执行,否则可能导致环境变量未注入,建议放在plugins数组的第一个位置
