logger

The logger operator is a utility function for RxJS observables that simplifies logging emitted values using different console functions. This operator is useful for debugging and monitoring the behavior of your observables during development.

Examples

Example 1: Basic Logging

Log emitted values using console.log:

import {logger} from 'ngx-lift';
import {of} from 'rxjs';

of([1, 2, 3]).pipe(logger()).subscribe();
// check your console for result

Example 2: Table Logging

Log emitted values using console.table for better visualization:

import {logger} from 'ngx-lift';
import {of} from 'rxjs';

of([1, 1, 2, 2, 3, 4, 4, 5]).pipe(logger('table')).subscribe();
// check your console for table result

Example 3: Other Console Methods

Use other console methods like warn, error, or info:

import {logger} from 'ngx-lift';
import {of} from 'rxjs';

of([1, 2, 3]).pipe(logger('warn')).subscribe();
of([1, 2, 3]).pipe(logger('error')).subscribe();
of([1, 2, 3]).pipe(logger('info')).subscribe();
