Usage
Use TypeScript for best in class instellisense.
the logconext module exposes an easy to use syntax for nodejs style async logcontexts.
let testLogger = new logcontext.Logger('testNamespace');
testLogger.scope(async () => {
testLogger.addData('id1', {
someData: 'someValue'
});
testLogger.log('hi');
testLogger.error(new Error('custom error message'));
setTimeout(() => {
outsideFunction(); // log scope will travel through callbacks and promises
}, 2000);
});
let outsideFunction = () => {
// Note:
// the below testLogger reference will have different contexts
// depending from which scope "outsideFunction" was called".
testLogger.log('some message');
};class Logger
import { Logger } from 'logcontext';
// instantiate new Logger
// argument optional, if left empty auto generated shortid will be used
let myLogger = new Logger('myNamespace');
// create a scope
myLogger.scope(async () => {
// everything that is appended to the call stack from inside here will have all appended context data available
// add some scoped context information
myLogger.addData('customerId', '12345678');
// will log something with priviously appended context of this scope in place
myLoger.log('awesomeText');
