Load balancer / proxy / router organized around Express/Connect-like middleware.
Distribute is a middleware-based API to expressively perform request routing / load balancing in Node.JS.
var http =srv = http;srv;srv;
Requests triggered by the
upgrade event (as a result of the
HTTP header) are handled by prepending the
ws flag each time you call
next parameter can take three signatures:
next()) will execute the next middleware. If no middleware is available, an error is displayed (refer to the "Default behaviors section")
Number), host (
Distribute adds two properties to request objects:
node-http-proxy data buffer.
For WS requests, the first packet of the stream, only present for legacy purposes.
Error object is passed to next, or when no middleware will
handle a given request, the default behavior is to show a
500 Internal Server Error (for HTTP requests) or the socket is ended
(WS requests). In development (ie: NODE_ENV is set to
stack trace is sent along with the error code.
If you want to define custom "error handling middleware", you can do so by adding a function with 4 parameters instead of 3 (in other words, with an arity of 4).
// regular requestssrv;// ws requestssrv;
It's not necessary to pass the error to
next to trigger the next error
Request data buffers are cleaned up automatically when:
