sprintf plugin for loglayer.
npm install @loglayer/plugin-sprintf
The sprintf plugin for loglayer provides printf-style string formatting support using sprintf-js.
It allows you to format your log messages using familiar printf-style placeholders if a transport does not support this behavior.
- LogLayer does not allow passing items that are not strings, booleans, or numbers into message methods like info, error,
etc, and would recommend that only string / boolean / number specifiers be used.
``bash`
npm install @loglayer/plugin-sprintf
`typescript
import { LogLayer, ConsoleTransport } from 'loglayer'
import { sprintfPlugin } from '@loglayer/plugin-sprintf'
const log = new LogLayer({
transport: new ConsoleTransport({
logger: console
}),
plugins: [
sprintfPlugin()
]
})
// Example usage
log.info("Hello %s!", "world")
// Output: Hello world!
log.info("Number: %d", 42)
// Output: Number: 42
