# Pretty Printing By default, Pino log lines are newline delimited JSON (NDJSON). This is perfect for production usage and long-term storage. It's not so great for development environments. Thus, Pino logs can be prettified by using a Pino prettifier module like [`pino-pretty`][pp]: 1. Install a prettifier module as a separate dependency, e.g. `npm install pino-pretty`. 2. Instantiate the logger with the `transport.target` option set to `'pino-pretty'`: ```js const pino = require('pino') const logger = pino({ transport: { target: 'pino-pretty' }, }) logger.info('hi') ``` 3. The transport option can also have an options object containing `pino-pretty` options: ```js const pino = require('pino') const logger = pino({ transport: { target: 'pino-pretty', options: { colorize: true } } }) logger.info('hi') ``` [pp]: https://github.com/pinojs/pino-pretty
