gnomon: Set a high threshold of 0.5 seconds for the elapsed time; exceeding which the timestamp will be colored bright red.

${npm

$ ${npm test} | gnomon --high ${0-5}

try on your machine

This command consists of two parts:

${npm test}: This is a placeholder that refers to the test script defined in the package.json file of a Node.js project. When you run npm test in the terminal, it executes the test script defined in the package.json file.
| gnomon --high ${0-5}: The | symbol is a pipe operator, used to send the output of the preceding command (${npm test}) to the next command (gnomon). In this case, the output of npm test command is piped to gnomon.

gnomon is a command-line utility used for displaying logs in a more readable and colorful format. It enhances the output by adding timestamps and relative time durations.

The --high ${0-5} argument passed to gnomon specifies the log level. In this case, it sets the log level to be displayed as 'high', which corresponds to log levels 0 to 5. '0' is the highest log level, displaying all logs, while '5' is the lowest, displaying only critical errors or failures.
