How to configure react-script so that it doesn't override tsconfig.json on 'start'

Question

I'm currently using create-react-app to bootstrap one of my projects. Basically, I'm trying to set up paths in tsconfig.json by adding these to the default tsconfig.json generated by create-react-app:

"baseUrl": "./src",
"paths": {
  "interfaces/*": [
    "common/interfaces/*",
  ],
  "components/*": [
    "common/components/*",
  ],
},

However, every time I run yarn start which basically runs react-scripts start, it deletes my changes and generates the default configurations again.

How can I tell create-react-app to use my custom configs?

I was able to do this by using advice from this issue.

Put the configuration options react scripts likes to remove in a separate file (e.g. paths.json) and reference it from tsconfig.json via the extends directive.

paths.json:

{
  "compilerOptions": {
  "baseUrl": "./src",
  "paths": {
    "interfaces/*": [ "common/interfaces/*"],
    "components/*": [ "common/components/*"],
    }
  }
}

tsconfig.json

{
  "extends": "./paths.json"
   ...rest of tsconfig.json
}
