Description

So I noticed this bug Whenever I have a console.log in my react-native.config.js . The same is logged when npx @react-native-community/cli config runs (which is expected) in terminal .

But since the same command is used to generate autoLinking.json . The log is present in autoLinking.json making the json file invalid

Reproducible Demo

React native config.json (Notice the console log on top)

Autolinking.json(Notice the top) . Invalid Json

Solution

I vibe coded this . Adding a supress console whenever config runs

Something like this

function suppressConsole() {
  const originalMethods = {
    log: console.log,
    warn: console.warn,
    error: console.error,
    info: console.info,
    debug: console.debug,
  };

  // Override console methods with empty functions
  console.log = () => {};
  console.warn = () => {};
  console.error = () => {};
  console.info = () => {};
  console.debug = () => {};

  return () => {
    // Restore original console methods
    console.log = originalMethods.log;
    console.warn = originalMethods.warn;
    console.error = originalMethods.error;
    console.info = originalMethods.info;
    console.debug = originalMethods.debug;
  };
}
