Package name: mitt
What's Changed
NodeNext
, fix #166 by @ Mister-Hope in #167New Contributors
Full Changelog: 3.0.0...3.0.1
Mitt 3.0 adds a couple nice new features.
1. Remove all handlers of a type:
Calling
.off("type")
with no handler argument now removes all listeners of that type (#123, #124, #129 - thanks @ sealice!).2. New, stronger typing:
It's now possible to define explicit types for events and their arguments (#114, thanks @ iyegoroff & @ deskoh):
3. Package Exports:
As of 3.0.0, the
mitt
package now uses Package Exports. This shouldn't change usage or anything, it just means you're more likely to end up using the ES Module version of Mitt when running in Node.Mitt 2 is out of preview!
It's written in TypeScript and ships type definitions (#107, thanks again @ jackfranklin!)
Event handlers are now stored in a Map instead of an Object.
The event handler Map is now exposed as
.all
: (#105, thanks @ jaylinski!)This patch update for the 2.0 prerelease fixes missing type exports (#101).
It also reduces size and improves performance (#100).
Possible Breaking Change:
mitt()
previously accepted an optional Object "event map" argument. In 2.0.0, events are stored in an actual JavaScript Map rather than as properties on a plain object:+ const map = new Map();
const events = mitt(map);
const foo = () => {};
events.on('foo', foo);
- map.foo // [foo];
+ map.get('foo') // [foo];
Now the good news: if you weren't using this argument,
mitt@2
isn't a breaking change for you.Also, Mitt is now written in TypeScript! Huge thanks to @ jackfranklin for doing all the work including setting up a much nicer build toolchain.
It's Mitt's first release since 2017! That's the thing about a 200 byte library - there's not a lot of code here to necessitate constant updates. Take it as a sign of stability.
This release is primarily an improvement to the TypeScript definition we ship with Mitt:
mitt()
with or withoutnew
in TypeScript (#60/#67 - thanks @ davidkpiano).on('*', handler)
now has types that pass the correct(event, data)
arguments (#76, thanks @ zbuttram)all
parameter, which lets you pass your own mapping of handler Arrays to Mitt, now has correct types (#73, thanks @ jesperzach).off()
) during emit (#65, thanks @ sqal & @ farskid)emit
andEventHandler
type annotations (#47, thanks @ rvikmanis)Commit messages
