​​If you ever used CSS sibling selectors, you know there’s only two. The + sibling combinator selects the first match that comes immediately after, and the ~ subsequent-sibling combinator matches all the ones that come after.
But there’s no way to select what came before. Either parent selectors or previous siblings selectors are simply not a thing.

When developing an npm package, you have confirm that it can actually be used. It’s great if tests pass, examples build, and demos run, but it’s broken if consumers can’t install it. npm provides a tool to help test packages before publishing, npm link.

Using Webpack with Babel to bundle ES6 web application is a well documented area with pieces of supporting content in various sources like StackOverflow and Git providing information on how to use ES6 for the Webpack config file. But Babel started using scope packages starting from version 7. Since a lot of documentation was written for Babel 6 but not Babel 7. This caused a fair amount of confusion to many developers (Author included). Since many OpenSource packages tend to be to occupied with their own repository to be able to provide full time support or update the documentation. This article hopes to fill up that gap till all the various packages move their versions up.

​​Recently I wrote a higher level overview of CSS-in-JS, mostly talking about the problems this approach is trying to solve. Library authors rarely invest time into describing the tradeoffs of their solution, sometimes it’s because they are too biased, sometimes they just don’t know how the users apply the tool, so this is an attempt to describe the tradeoffs I have seen so far. I think it is important to mention that I am the author of JSS, so I should be considered biased.
