Essentials
Development Formatting
The [pino-pretty](https://github.com/pinojs/pino-pretty) module can be used to
format logs during development:
Transports & Log Processing
Due to Node's single-threaded event-loop, it's highly recommended that sending,
alert triggering, reformatting, and all forms of log processing
are conducted in a separate process or thread.
In Pino terminology, we call all log processors "transports" and recommend that the
transports be run in a worker thread using our pino.transport API.
For more details see our Transports⇗ document.
Low overhead
Using minimum resources for logging is very important. Log messages
tend to get added over time and this can lead to a throttling effect
on applications – such as reduced requests per second.
In many cases, Pino is over 5x faster than alternatives.
See the Benchmarks document for comparisons.
Bundling support
Pino supports being bundled using tools like webpack or esbuild.
See Bundling document for more information.
