rescript-service-worker v1.0.0

rescript-service-worker

This package is the home of BuckleScript bindings for the JavaScript service worker API. It is actively in use but has not been exhaustively tested.

Long-term support

This package is currently supported but may go long periods of time without fresh commits because it is something like "finished". Yes, software is like fashion, and fashion is never finished, and I will try to upgrade the ReScript language version from time to time, but unless there are significant defects in this project you can generally consider this project to be as stable as the ReScript language and the ServiceWorker API.

This is to say: Don't be alarmed by the lack of recent commits! Stability is good! And don't be afraid to open issues.

Installation

npm i rescript-service-worker

Usage

This is meant to be a tight binding around the JavaScript API, and is intended to feel idiomatic to JavaScript. Refer to this article which documents usage from registration to caching to fetch event handling.

Notes

on EventTargets

I'm hoping to crack the code for how to perfectly enforce types onto addEventListener... someday. I haven't done it yet. For now, stick to the function-valued properties. Those are typed pretty well.

on NavigationPreloadManager and NavigationPreloadState

My current thinking is to omit NavigationPreloadManager and NavigationPreloadState because they're too dependent on ByteString, and I don't want to expand the scope of my project. If you badly need these types or if you know of a ByteString implementation I could depend on, feel free to open an issue.

on ServiceWorkerGlobalScope

It's not fully implemented because it implements a ton of other interfaces. Fully implementing it is a nice-to-have. If there's something you need from this type that I haven't implemented, feel free to open an issue--it'll help me prioritize.

Also, currently the navigator property lives in 'ServiceWorkerGlobalScope', even though technically it's a part of WorkerGlobalScope.

on TODOs

I put in a TODO everyplace where there's a (non-deprecated) method or type I didn't implement, whether or not I had any intention of implementing it. If you go looking for something in here and find a TODO in its place, feel free to open an issue or submit a pull request and we can talk about how to get you what you need.

License

Because I have merely translated the API from the JavaScript specification into ReScript with no implementation, I do not consider anything in this repository to be copyrightable.

As a courtesy, I have included a copy of the MIT license anyway just in case your lawyers are fussy about this sort of thing. If you would like a different license, just let me know, and I will write one for you.
