@alloc/log-format

Evaluate console.log format specifiers (eg: %O) before logging.

Format specifiers:

• %O Use pretty-format before insertion
• %s Use String(value) before insertion
• %f Use Number(value) before insertion
• %d Use Math.floor(value) before insertion (alias: %i)

Example

import format from '@alloc/log-format'

format('a: %O, b: %O', /.+/, new Date)
// => 'a: /.+/, b: 2020-06-26T18:39:40.258Z'

format({ a: [1, 2], b: new Set([3, 4]) })
// => '{"a": [1, 2], "b": Set {3, 4}}'
