Always verify configuration values against official documentation and test across target platforms before committing. Invalid configuration values can cause build failures, runtime errors, or platform-specific issues that are difficult to debug.
Key validation practices:
Example of problematic configuration:
// tsconfig.json - Invalid lib value
{
"compilerOptions": {
"lib": ["es2022", "esnext.disposable", "DOM"] // โ "esnext.disposable" is not valid
}
}
// Fixed version
{
"compilerOptions": {
"lib": ["es2022", "DOM"] // โ
Valid lib values only
}
}
This prevents configuration-related build failures and ensures consistent behavior across development environments.
