LogLayer

Typescript Tips ​

Use ILogLayer if you need to type your logger ​

ILogLayer is the interface implemented by LogLayer. By using this interface, you will also be able to use the mock MockLogLayer class for unit testing.

typescript
import type { ILogLayer } from 'loglayer'

const logger: ILogLayer = new LogLayer()

Use LogLevelType if you need to type your log level when creating a logger ​

typescript
import type { LogLevelType } from 'loglayer'

const logger = new LogLayer({ 
  transport: new ConsoleTransport({
    level: process.env.LOG_LEVEL as LogLevelType
  })
})

Use LogLayerTransport if you need to type an array of transports ​

typescript
import type { LogLayerTransport } from 'loglayer'

const transports: LogLayerTransport[] = [
  new ConsoleTransport({
    level: process.env.LOG_LEVEL as LogLevelType
  }),
  new FileTransport({
    level: process.env.LOG_LEVEL as LogLevelType
  })
]

const logger = new LogLayer({ 
  transport: transports,
})
