Lightweight informative modern console logging.

Hi there 👋

I enjoy working on open source, but the work I've been doing for the last five years at Medallia is not yet open source.

Developer, mentor, and leader with a passion for developer happiness and efficiency, building maintainable and testable code, and the fast moving world of JavaScript, TypeScript and Node.

Passionate and experienced with regards to tooling, security, performance, E2E testing, modern JavaScript best practices.

Contributor to open source projects like npm, Yarn, Jest.

I created these years ago when nothing like them existed. They're still fairly well used!

logging's Issues

TypeError: Illegal access to a strict mode caller function.

I got this :

/home/bbigras/node-ftp/app.js:323:23 is

log("- Disconnected");

Other uses of the log() command worked fine.

[Question] Looks good, but what is it `Feature` suffix?

Maybe I just don't know what it is mean in js world, I searched logger for my angular project, and find your library, looks really pretty, but what is it mean Feature?, for example: WARNING Feature.

createLogger is not a function

Got TypeError: createLogger is not a function in javascript. Same code works in typescript tho.

Code:

import createLogger from 'logging';

const logger = createLogger('FeatureName');

logger.info('Interesting');

logging 3.3.0
nodejs 16.15.1

False claim of supporting color?

Took a look at the code, and looks like you don't actually support color yet.... Is this correct?

Output is the same as console.log

Following the instructions (in an Expo project running with expo start --dev-client) I get output that is indistinguishable from console.log (no colors, no date, no feature).

Some formatting chars show up in message

Formatting characters inconsistently show up in the message. For example, (INFO) blah shows up as INFO blah with "INFO" in cyan, as expected. However !ERROR! blah appears exactly as written - !ERROR! blah which is inconsistent with the previous behavior. The problem appears here and is rather simple to fix - you only need to call substring as you do with the other colors.

Configure log level

I'd like to silence messages below a certain level.

Bolding does not work

Contrary to the last commit made, bolding a color by doubling !! doesn't work.

Using Node.js v5.5.0 on OSX:

Support for log levels?

It would be a nice addition if the app paid attention to the environment variables DEBUG, LOG_LEVEL, and LOG_DEBUG.

i.e. LOG_LEVEL=info LOG_DEBUG=myapp,myapi node index.js

Using that example it would cause only INFO and above to be output and only from 'myapp' or 'myapi'.

TypeError: createLogger is not a function

Hi! I thought I'd test-drive this nice looking logging module. However, ran into an issue from the start go with node v6.10.1 and logging v3.2.0 via npm.

const createLogger = require('logging');  
const log = createLogger('xmodem');

This results in:

const log = createLogger('xmodem');
            ^
