Create-react-app

一、为Create-react-app项目配置支持绝对路径引入模块

Messing around I just found one setting that works without craco for the absolute paths:

1 - Update .env file to NODE_PATH=./;

2 - Create one tsconfig.paths.json:

{
  "compilerOptions": {
    "baseUrl": ".",
    "paths": {
      "src/*": ["src/*"]
    }
  }
}
3 - Add this as your first entry in tsconfig.json:

"extends": "./tsconfig.paths.json",
Now everything should work fine, just reference the src/ folder in your imports instead of @.

YES, CRA will complain about the tsconfig.json absolute paths and stuff, but... VSCode seems to work pretty well with it and I think other IDEs will just as well.

EDIT: CRA complains but don't really remove the lines because it extends from the paths.json file so it can't modify it!

二、"Cannot compile namespaces" error with --isolatedModules and no namespaces

A global file cannot be compiled using '--isolatedModules'. 
Ensure your file contains imports, exports, or an 'export {}' statement.
