如何查看node / express的console.log / stdout或console.error / stderr输出？

Question

When running express locally, I can see console.log/console.error output in the console. When running on a server, where is this information logged?

Answer 1

How is express running on your server?

If, for example, you are running it via pm2, pm2 will capture stdout and stderr and log it to a file(s). The details of where this will be logged are specific to the host process.

In the pm2 case, the logs default to ~/.pm2/logs
