Always use the proper logger instance instead of console methods, and format error logs with structured data objects rather than string concatenation. Console logging methods like console.error can lead to log flooding in production and lack proper log level controls. Structured logging with error objects enables better log parsing, monitoring, and debugging.
Avoid:
console.error('Schema validation error: Detected unconverted Zod schema');
logger.error(`Failed to scrape URL ${url}: ${scrapeResponse.error}`);
Use instead:
logger.error('Schema validation error: Detected unconverted Zod schema', {
type: val._def?.typeName,
keys: Object.keys(val),
hasZodProperties: !!(val._def || val.parse || val.safeParse)
});
logger.error(`Failed to scrape URL ${url}`, { error: scrapeResponse.error });
This approach provides consistent logging behavior across environments, enables proper log level filtering, and creates structured data that monitoring tools can easily parse and alert on.
