一种用于加载配置的通用解决方案。
A universal solution for loading configurations.
Configuration is hard, especially when you want to build an ecosystem of your tools.
You want your tools to be general and easy to use, you allow your config to be defined in a custom field of package.json.
You want your tools to be easy to integrate, you allow the configs to be defined in other tools' configurations like vite.config.js or webpack.config.js.
You want the configs to be agnostic and probably need to be load by IDE, you create new config files like .myconfigrc.
You want the configs to also be flexible and dynamic, you make your config files a JavaScript file, like my.config.js.
Then you want users to be able to use ESM and TypeScript, you also make your config accepting .ts or .mjs.
So users' project root end up with a lot of config files like .npmrc, rollup.config.js, .eslintrc, tsconfig.json, jest.config.js, postcss.config.js, nuxt.config.js, vite.config.cjs, windi.config.ts, etc. And each of them use different syntax, in JSON, in CJS, in ESM, in TypeScript, in INI, in TOML...
unconfig can't solve this fragmentation entirely, but it's trying to make loading them easier for tool authors.
npm i unconfig
For example, to load config for my.config:
…
unconfig supports loading ts, mjs, js, json by default.
