levels

perj levels Option

Type: Object

Default:

{
    fatal: 60,
    error: 50,
    warn: 40,
    info: 30,
    debug: 20,
    trace: 10
}

Valid: Object with keys set to Number values.

Description:

The levels option object is used to build the logger level functions. The key values, such as 'trace' become the function names. The Number value is used in conjunction with the level option.

Once the levels have been applied to the log object, you can call each level like so: log.warn('Don't do that!')

The following table gives a summary of the levels and when to use them:

level	lvl	When to Use
fatal	60	Stop errors. Process crash.
error	50	Processing failed for a known or unknown reason.
warn	40	Something went wrong however it is not critical.
info	30	Hey Dad? I dug a hole! (see The Castle).
debug	20	When you need to find out where something happened.
trace	10	When you need to know everything that happens.

Example:

This example changes the levels significantly:

const perj = require('perj')
const levels = { silly: 100, crazy: 200, nuts: 300 }
const log = perj.create({ levels, level: 'silly' })

log.silly('This is a very silly log entry')
log.crazy('This log entry is just looney!')
log.nuts('And this one is a few screws loose')

// Standard out:
