@wbe/debug
Tiny debug tool (~500 bytes) for terminal and browser inspired by visionmedia/debug API.
Motivation
@wbe/debug
was built in order to be as light as possible and for the personal challenge to coding
a debugger, for terminal and browser, as the same way as the great visionmedia/debug tool.
Installation
$ npm install -s @wbe/debug
debug node
DEBUG=* node file.js
const debug = require("@wbe/debug")
debug('foo'); // "foo"
process.env.DEBUG
value can be defined as a specific namespace too:
DEBUG=namespace node file.js
Only debug function declaration with namespace
declared as namespace will be printed in the console:
// add the namspace as returned function paramater
const debug = require("@wbe/debug")("namespace")
debug('foo'); // "namespace foo"
process.env.DEBUG
value accept one glob parameter level:
DEBUG=config:* node file.js
Every debug function declaration with namespace config:{somestring}
will be printed.
debug in browser
In the same way as nodejs usage, debug
is browser compatible with the same API. The only difference is
we need to set the current namespace in localStorage.
Add on your browser localStorage:
localStorage.debug = "foo"
Use debug in javascript:
const debug = require("@wbe/debug")("foo")
debug('bar'); // "foo bar"
// or with es6 import
import debug from "@wbe/debug"
const log = debug('foo');
log("bar") // "foo bar"
Example
Test browser example:
npm i && npm run dev:browser
Test node example:
npm i && npm run dev:node
