Q: What are the future goals of the library?The library's overall goals are to continue bringing popular patterns from FP languages into TypeScript.
Q: How are new features decided and planned?Most of the development stems from dogfooding the library in personal projects.
User feedback is also extremely important - check out the question at the bottom to see why.
Q: Is this library intended to be used on the front-end or the back-end?Purify is intended to be used both on the front-end and the back-end.
Everything from the build config to the API choices and features included is made with this in mind.
Q: Is this library intended to be part of an ecosystem of likeminded libraries or handle additional functionality itself?Purify is intented to be a single library with a focus on general purpose API.
Official bindings to popular libraries like React, Angular, Express etc. are not planned and most likely won't happen.
Q: What is the timeline for the new releases?There are no exact dates for upcoming versions of Purify.
Now that the library is post-v1 you can expect a more irregular release schedule.
Q: Should I expect breaking changes?Situations in which you can definitely expect breaking changes are:
There is a new TypeScript release that allows for more type safety
There is a new TypeScript release that makes expressing certain constructs (like HKTs) possible
ECMAScript proposals that allow for a more elegant API (like the pipeline operator) reach stage 3
TL;DR - Breaking changes will be rare, but if the language evolves in a way that makes FP code easier to write then there will be changes for sure.
Q: What should future contributors focus on?Pull request for bugfixes or documentation improvements are always welcome, but trying to add new methods via a PR most likely won't be accepted.
Sharing use cases or pain points are the fastest way to see something implemented in the library and I'll greatly appreciate it.
