Línea de trabajo

Lee src/metro/index.ts para revisar los comentarios de las opciones y la declaración duplicada de hexColors; después, compara el valor predeterminado documentado con src/metro/typescript.ts. Ejecuta bash reproduce.sh para inspeccionar la declaración generada. La tarea está completa cuando ambos comentarios de las opciones aparecen en dist/typescript/module/src/metro/index.d.ts, el valor predeterminado coincide con el nombre de archivo generado y se resuelve la declaración duplicada.

Descripción

Before submitting a new issue
  • I tested using the latest version of the library, as the bug might be already fixed.
  • I tested using a supported version of react native.
  • I checked for possible duplicate issues, with possible answers.
Bug summary

WithReactNativeCSSOptions in src/metro/index.ts documents typescriptEnvPath and disableTypeScriptGeneration with Defaults types-env.d.ts, where setupTypeScript writes react-native-css-env.d.ts (src/metro/typescript.ts), and writes both comments as /* */, which the built declaration drops, so an editor shows neither. The interface also repeats hexColors?: boolean, which CompilerOptions, the interface it extends, declares.

Steps to reproduce
  1. Clone the reproducer branch, which is main at df32ce3 with one file added, reproduce.sh, and install: 
    git clone --branch repro/metro-option-comments https://github.com/YevheniiKotyrlo/react-native-css
cd react-native-css
yarn install
  2. Run bash reproduce.sh.

reproduce.sh:

#!/usr/bin/env bash
# The default src/metro/index.ts documents, the one setupTypeScript writes, and the two options as yarn build publishes them
set -u

grep -n "types-env" src/metro/index.ts
grep -n "envPath = " src/metro/typescript.ts

yarn build > /dev/null 2>&1 || {
  echo "yarn build failed"
  exit 1
}
grep -n -B1 -E "typescriptEnvPath|disableTypeScriptGeneration" dist/typescript/module/src/metro/index.d.ts

Expected: the documented default is react-native-css-env.d.ts, and each option keeps its comment in dist/typescript/module/src/metro/index.d.ts.

Actual: both comments name types-env.d.ts, and the built declaration has neither.

The run's output on main at df32ce3, Windows 11, Node 26.12.1 
13:  /* Specify the path to the TypeScript environment file. Defaults types-env.d.ts */
15:  /* Disable generation of the types-env.d.ts file. Defaults false */
10:  envPath = "react-native-css-env.d.ts",
4-export interface WithReactNativeCSSOptions extends CompilerOptions {
5:    typescriptEnvPath?: string;
6:    disableTypeScriptGeneration?: boolean;
