@sthom/logging-config-react
Logging configuration for Javascript and Typescript.
This exists because the only way to stop my brain from shouting "you need to make a terrible logging library" is to make a terrible logging library.
Make sure to look at the original module: https://www.npmjs.com/package/@sthom/logging-config.
Usage
All exports from @sthom/logging-config are re-exported in @sthom/logging-config-react, so you don't need both in your dependencies.
Basic example:
import useLogger from "@sthom/logging-config-react";
// In your component
const logger = useLogger();
logger.info("Hello world!");With a tag at the start:
import Logger from "@sthom/logging-config";
const logger = useLogger("MyComponent");
logger.info("Hello world!"); // Logs: [MyComponent] Hello world!Configuration using context:
import {
LoggingConfiguration,
LoggingConfigurationContext
} from "@sthom/logging-config-react";
const config = new LoggingConfiguration("ERROR");
// In your component
<LoggingConfigurationContext value={config}>
{/* Rest of your app */}
</LoggingConfigurationContext>;
// If your log level changes at run-time, you'll want to memoise the config object.
// This is just a measure to prevent unnecessary re-renders of your app.
const level = /* your logic */;
const config = useMemo(() => new LoggingConfiguration(level), [level]);Log levels
The following levels, in order of increasing severity, are available:
- TRACE:
logger.trace - DEBUG:
logger.debug - INFO:
logger.info - WARN:
logger.trace - ERROR:
logger.error - FATAL:
logger.fatal
Support for custom levels may come in the future.
