Announcing Precomputed Reachability Analysis in Socket
Socketβs precomputed reachability slashes false positives by flagging up to 80% of vulnerabilities as irrelevant, with no setup and instant results.
Welcome to LemonLog! The zesty, easy-to-use logging solution for your Node.js applications. Whether you're debugging your latest feature or keeping an eye on production issues, LemonLog is here to brighten your day (and your console) with colorful, structured logs. π
Install LemonLog
npm install lemonlog
Usage
First, require and create a new instance of LemonLog in your project:
const log = require('lemonlog')('MyApp');
or
import LemonLog from 'lemonlog';
const log = new LemonLog('MyApp');
Then, log away:
log.info('This is an info message!');
log.debug('Hereβs something you might find interesting...', { emoji: "π" });
log.inspect('Inspecting a deeply nested object', { a: { b: { c: { d: 1 } } } });
log.warn('Warning! Warning! π¨');
log.error('Oops! Something went wrong. π₯');
Use DEBUG to filter logs:
$ DEBUG=* node demo/demo.js
myApp:info ------ This is an info message { a: 1 } +0ms
myApp:debug ----- This is a debug message +0ms
myApp:inspect --- [
myApp:inspect --- 'This is a full json depth inspect message',
myApp:inspect --- {
myApp:inspect --- a: { b: { c: { d: 1 } } }
myApp:inspect --- }
myApp:inspect --- ] +0ms
myApp:warn ------ This is a warning +0ms
myApp:error ----- This is an error +0ms
myApp:debug ----- [ 'Custom success message' ]
myApp:debug ----- { return: 'ok' } +0ms
myApp:error ----- { return: 'error' }
myApp:error ----- [ 'Custom error message' ]
myApp:error ----- null +0ms
myApp:debug ----- Success: { return: 'ok' } +1ms
myApp:error ----- { return: 'error' }
myApp:error ----- null +1ms
$ DEBUG=myApp:error* node demo/demo.js
myApp:error ----- This is an error +0ms
myApp:error ----- { return: 'error' }
myApp:error ----- [ 'Custom error message' ]
myApp:error ----- null +0ms
myApp:error ----- { return: 'error' }
myApp:error ----- null +1ms
Customize Your Callbacks
Handle logs with your own custom logic:
async function someAsyncFunction(fail, cbk) {
if (fail) {
cbk({ return: "error" }, null);
} else {
cbk(null, { return: "ok" });
}
}
// Custom callback example
someAsyncFunction(false, log.callback("Custom success message"));
someAsyncFunction(true, log.callback("Custom error message"));
// Exec example
someAsyncFunction(false, log.exec(result => {
log.debug('Success:', result);
}));
someAsyncFunction(true, log.exec(result => {
log.debug('Error:', result);
}));
We believe that logging shouldn't just be about capturing information. It should be a delightful part of your development process. With LemonLog, we aim to bring a little joy and color to your console, making it easier and more fun to sift through your logs.
