As part of the e18e initiative, the ecosystem cleanup project is a community effort to collaborate on cleaning up technical debt in the JS ecosystem.
Our goal is to provide a cleaner, faster and simpler dependency tree in the JS ecosystem for those who are concerned with it.
Packages often have dependencies, and those dependencies themselves have dependencies, and so on. This is fine and expected with how dependency trees are structured.
However, over the years many of these deepest dependencies are long since obsolete utilities, polyfills, and so on. At the time they were introduced, they were important and had their use, but are now arguably redundant to most of us.
For example, polyfills for Array.prototype.includes are often found
deep in most projects' dependency trees, and yet this feature has been available
since Node 6 (released in ~2016).
Similarly, we have all collected "micro packages" over time without realising
it. These are very small (often one-liners) packages we depend on to do
simple pieces of logic the JavaScript language already allows us to do. For
example, is-string, is-number, is-nan, etc.
There are many reasons you could argue these are a bad idea. Security, complexity, install time, bundle size and so on. We unnecessarily download, install and include hundreds of these packages when the platform already provides the same functionality.
Some of these packages do have their use, and a small group of consumers strongly disagree with removing them (usually the creators of said packages).
For example, one primary argument for using the polyfill-like packages is that a third-party package can override built-ins and break another package's code. To counter this, these packages use a custom implementation/wrapper around the native functionality instead of using the native functionality directly (since nobody can override the wrapper).
If you need this kind of protection against the way JavaScript works, then of course this cleanup is not for you.
This is not an easy problem to tackle since these packages are so deeply embedded in our system, far below the packages we knowingly install day by day.
To make things easier, we will be splitting up the work into much smaller and more manageable tasks to gradually chip away instead of a big bang solution.
Some examples of what we will be doing:
- Remove these packages from popular packages as direct dependencies
- Fork packages which have officially stated they will never move off these
packages
- Where possible, make these forks track the original source repo (i.e. catch up from main when the origin changes).
- Replace redundant polyfills with native functionality in popular packages
- Replace these packages with cleaner alternatives
The main goal is to contribute to the packages we actually use (which depend on these things), and as a final resort, fork what is immovable.
If you'd like to contribute towards the effort, simply find an issue you would like to help with and just let us know with a reply that you are going to tackle it. We will be happy to help you along the way.
A good place to start is the guide.
