Author	SHA1	Message	Date
Damien Arrachequesne	0317a077be	chore(release): 3.0.1 Diff: https://github.com/socketio/socket.io/compare/3.0.0...3.0.1	2020-11-09 10:27:58 +01:00
Damien Arrachequesne	d00c0c0d9d	docs(examples): update examples to Socket.IO v3 Other examples need some additional work (Redis adapter migration, ...).	2020-11-09 10:19:40 +01:00
Avi Vahl	f62f180eda	fix: export ServerOptions and Namespace types (#3684 ) @types/socket.io used to export these.	2020-11-09 08:58:14 +01:00
Damien Arrachequesne	50671d984a	fix(typings): update the signature of the emit method The previous signature was not compatible with EventEmitter.emit(). The typescript compilation threw: ``` node_modules/socket.io/dist/namespace.d.ts(89,5): error TS2416: Property 'emit' in type 'Namespace' is not assignable to the same property in base type 'EventEmitter'. Type '(ev: string, ...args: any[]) => Namespace' is not assignable to type '(event: string \| symbol, ...args: any[]) => boolean'. Type 'Namespace' is not assignable to type 'boolean'. node_modules/socket.io/dist/socket.d.ts(84,5): error TS2416: Property 'emit' in type 'Socket' is not assignable to the same property in base type 'EventEmitter'. Type '(ev: string, ...args: any[]) => this' is not assignable to type '(event: string \| symbol, ...args: any[]) => boolean'. Type 'this' is not assignable to type 'boolean'. Type 'Socket' is not assignable to type 'boolean'. ``` Note: the emit calls cannot be chained anymore: ```js socket.emit("hello").emit("world"); // will not work anymore ```	2020-11-08 00:07:56 +01:00
Damien Arrachequesne	8a69f15437	chore: restore package-lock.json file	2020-11-05 22:25:35 +01:00
