A TypeScript decorator for classes that logs all method usages using the debug
package. Logging is enabled using the DEBUG environment variable – see the
debug package for details.
The decorator can be used directly and it will log to a namespace matching the class name it is decorating. An execution
of new HelloWorld().main('World') below will result in HelloWorld main("World"); being logged.
import DebugLogging from '@cameronhunter/debug-logger';
@DebugLogging
class HelloWorld {
main(name: string) {
console.log(`Hello ${name}!`);
}
}The decorator also accepts an optional namespace that will be used in addition to the class name it is decorating. An
execution of new HelloWorld().main('World') below will result in my-debug-namespace:HelloWorld main("World"); being
logged.
import DebugLogging from '@cameronhunter/debug-logger';
@DebugLogging('my-debug-namespace')
class HelloWorld {
main(name: string) {
console.log(`Hello ${name}!`);
}
}The decorator can be preconfigured and shared. For example, we can configure a debug logger with a custom namespace and
export it for use around an application. An execution of new HelloWorld().main('World') below will result in
my-namespace:HelloWorld main("World"); being logged.
import DebugLogger from '@cameronhunter/debug-logger';
const CustomLogger = DebugLogger('my-namespace');
@CustomLogger
class HelloWorld {
main(name: string) {
console.log(`Hello ${name}!`);
}
}
