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 🙏

capture-console-logs

v2.0.1-rc.1

Published

Capture your console in a way that it is easy to reproduce its logs elsewhere

Downloads

Readme

Most of the existing libraries capture and return the results from stderr and stdout. This although useful, makes it really hard to recreate the original console statements if you need to

This package provides a way to do so by overriding the console methods for the duration of the capture.

Installation

This package is published on npm and can be installed using

npm i capture-console-logs

Example

const CaptureConsole = require("capture-console-logs").default

const cc = new CaptureConsole();
console.log("ping pong") // not captured

cc.start()

console.log("simple log")
console.info("informative log", {a:1})
console.error(new Error("Our small petty error"))
console.warn("Better Watch Out!")
console.debug("please work1")

cc.stop()
console.log(cc.getCaptures());

The output for the above example is

[
  { function: 'log', args: [ 'simple log' ], ts: 1673463210311 },
  {
    function: 'info',
    args: [ 'informative log', '{"a":1}' ],
    ts: 1673463210311
  },
  {
    function: 'error',
    args: [
      '{"stack":"Error: Our small petty error\\n    at Object.<anonymous> (/Users/navdeep/Desktop/nsr/test/me/index.js:10:15)\\n    at Module._compile (node:internal/modules/cjs/loader:1105:14)\\n    at Object.Module._extensions..js (node:internal/modules/cjs/loader:1159:10)\\n    at Module.load (node:internal/modules/cjs/loader:981:32)\\n    at Function.Module._load (node:internal/modules/cjs/loader:822:12)\\n    at Function.executeUserEntryPoint [as runMain] (node:internal/modules/run_main:77:12)\\n    at node:internal/main/run_main_module:17:47","message":"Our small petty error"}'
    ],
    ts: 1673463210312
  },
  {
    function: 'warn',
    args: [ 'Better Watch Out!' ],
    ts: 1673463210312
  },
  { function: 'debug', args: [ 'please work1' ], ts: 1673463210312 }
]

Note: By default, while capturing original logs are not displayed in the console. To allow execution while capturing, pass allowOriginalExecution as true in the start command

cc.start(true)

Whenever needed, you can use the flush method to clear all captured logs.

You can also create the original log using these captures as follows

const CaptureConsole, {makeOriginalLog} = require("capture-console-logs")

// [...]

const captures = cc.getCaptures();
captures.forEach(log => {
  CaptureConsole.makeOriginalLog(log)
})

This code is barely tested and so PR's, improvements and issues are all welcome
