Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

logger

Probably the simplest logger out there. Now with a little more kick.

Version 2 introduces breaking changes, as well as new FileLogger and MongoDbLogger classes.

How to Use it

Use it in the Browser or Node.js

const logger = new Logger("App", {
   level: "debug",     // or LoggerMessage.level.debug
   timestamp: "utc"    // or LoggerMessage.timestamp.utc
});

// Prints to a console
// [Mon, 01 Jul 2019 23:41:04 GMT] [DBG] [App] Initializing
logger.debug("Initializing"); 

Use it for File Logging in Node.js

const {FileLogger} = require('@voliware/logger');

const filelogger = new FileLogger("App", {
    context: "User",
    filepath: "/path/to/file.log",
    timestamp: false,
    maxlogs: 10000,
    maxsize: 1024 * 1000,
    //multiplefiles: true // Not yet supported
});

// Logs to a file
// [INF] [App] [User] Logged in
logger.info("Logged in"); 

Use it for MongoDB Logging in Node.js

const {MongoDbLogger} = require('@voliware/logger');

// Setup MongoDB example
const url = "mongodb://localhost:27017/logger-testing?retryWrites=true&w=majority"
const mongoclient = new MongoClient(url, {
    useNewUrlParser: true,
    useUnifiedTopology: true
});
await mongoclient.connect();
const mongodb = mongoclient.db("logger-testing");
await mongodb.createCollection("logs");

// Create the logger
const mongodblogger = new MongoDbLogger("App", {
    collection: mongodb.collection('logs')
});

Single Logger

If you want to use a single logger throughout, but want to change the [Name] or [Context] per message, you can pass a LoggerMessage object to the associated log function.

logger.debug(new LoggerMessage({
    name: "[Social]",
    context: "[Posts]",
    text: "Bob posted something"
}))

Logger API

logger.verbose("verbose log");
logger.debug("debug log");
logger.info("info log");
logger.warning("warning log");
logger.error("error log");
logger.log("hello", "debug");
logger.log("hello again", Logger.level.debug);
logger.name = "App";
logger.context = "Users";
logger.timestamp = "numeric";
logger.level = "info";
logger.enabled = false;
logger.maxlogs = 1000;
logger.maxlogs = 0; // no limit
logger.maxsize = 1024 * 1024;
logger.maxsize = 0; // no limit

FileLogger API

logger.console = false; // don't also print to console
logger.filepath = 'path/to/file.ext';
logger.maxsize = 1024 * 1024;
logger.maxsize = 0; // no limit
//logger.multiplefiles = true; // future
logger.clear();
logger.delete();
logger.rename('new/file/name.ext');

MongoDbLogger API

logger.console = false; // don't also print to console
logger.collection = collection; // native MongoDB collection
logger.clear();
