Some great videos I watched this week

Reveal testing weakspots in your JavaScript code with Jest Coverage

If you've ever been stuck on what tests to write for your code, Jest's coverage reports can be a great tool for showing what sections of your codebase are not tested yet. It becomes even more powerful when used in combination with Continuous Integration (CI), as it can be automated and even block pull requests from merging, which we'll show in this video.

Visual Regression Testing with Storybook's Chromatic

When building a design system or component UI it becomes more and more difficult to catch visual bugs as the project scales. This is especially true when changing one component affects other components that use it, and QA doesn't know to check every component it's related to.

Visual regression testing is an extra layer of security there, and Storybook's Chromatic is the most polished one I have tried. So let's set a new project up and show off some of the features Chromatic offers.

JSEncrypt

A Javascript library to perform OpenSSL RSA Encryption, Decryption, and Key Generation.

GitHub logo travist / jsencrypt

A Javascript library to perform OpenSSL RSA Encryption, Decryption, and Key Generation.

Website

http://travistidwell.com/jsencrypt

Introduction

When browsing the internet looking for a good solution to RSA Javascript encryption, there is a whole slew of libraries that basically take the fantastic work done by Tom Wu @ http://www-cs-students.stanford.edu/~tjw/jsbn/ and then modify that code to do what they want.

What I couldn't find, however, was a simple wrapper around this library that basically uses the library practically untouched, but adds a wrapper to provide parsing of actual Private and Public key-pairs generated with OpenSSL.

This library is the result of these efforts.

How to use this library.

This library should work hand-in-hand with openssl. With that said, here is how to use this library.

  • Within your terminal (Unix based OS) type the following.
openssl genrsa -out rsa_1024_priv.pem 1024
  • This generates a private key, which you can see by doing the following...
cat rsa_1024_priv.pem
  • You can then copy and paste this in the Private Key…

so, I got the newsletter from you. It said, "We will give a Udemy Course to one of you". But I think you forgot to mention that in this post.

you said "We are giving away any course you need on Udemy. Any price any course."

Please try to be clear in the future. Otherwise, people would think this is just another clickbait.

Hi @mrpmohiburrahman . Sorry if we weren't clear enough, we cannot give a Udemy course to all of our members, as you can understand it would be much too expensive. As this is a giveaway there will only be one winner randomly drawn from our readers. We are giving away any course the winner wants, not any course in general.
For now, we're giving only resources made by us (for free) to all our users. Even if in the near future we will try to give also external elements, or at least discounts on those. Mainly via partnership or sponsors. That's what we're thinking about for example for next month's giveaways.
Let me know if you have any other questions.
