endpoint-wrapper.io - socket emitting everywhere!
endpoint.io is express middleware that wraps around socket.io, which manages the socket object as a singleton, and exposes it
This packages requires you to install and manage
socket.io
separately, and pass it to this package. If you would rathersocket.io
be fully abstracted and managaged, use endpoint.io instead.
Usage (high-level)
Invoke endpoint-wrapper
, passing the socket.io
package as the first argument, and http
as the second. This must be done before using inject
, so add it near the top of your file, ususally app.js
let http = ;let socketio = ;let io = socketio http; // socket.io should NOT be invoked here.// `io` is the same object socket.io returns.
You can then inject io
into express middleware in any files (even seperate route files), and gain access to it via res
let inject = ; router;
res.emit
This method emits an event and sends a 200 status if it succeeds (and 500 if it fails);
let inject = ; router;
In the body of the response, the information emitted by the method is also made available.
endpointio.get
You can also get your io
outside of express middleware in arbitrary context via get
let endpointio = ; ;
Enjoy emitting events from everywhere!
Usage (alternate setup)
Rather than requiring in endpoint.io and invoking it to get setup, you can additionally deconstruct the main function as endpointio
. This might be useful if you want to use both the main function and inject
/get
in the same file, and really, really hate requiring in the same module twice.
let http = ;let socketio = ;let endpointio inject get = ;let io = ; app;
