rxjslog

Log RxJS events nicely to the console.

The next, error and complete events have their own icon and the log messages have their own color so they stand out between the other log messages.

Rxjslog works in both the browser as in Node.js environments.

Install

npm install rxjslog

Example code

import {interval} from 'rxjs';
import {take} from 'rxjs/operators';
 
import {log} from "rxjslog";
 
const myObservable = interval(500).pipe(take(3));
 
myObservable.pipe(log("myObservable"))
    .subscribe();

Example output

Configuration

You can configure the icons and colors used.

For the next, error and complete complete log messages, you can set the icon and color.

To stay compatible with Node.js log messages, use only one of these colors: black, red, green, yellow, blue, magenta, cyan and white.

Example:

import {logConfig} from "rxjslog";

logConfig({ error: { icon: "❗", color: "red" } });
