Cleans up old sockets before listening
Cleans up old sockets before listening on them.
When trying to listen on a socketfile, a server will emit an
EADDRINUSE error even if the socket is no longer alive. @dshaw came up with a rad solution but it still doesn't check to see if the socket is dead before blowing it away.
cleansocket ensures that the file is indeed a socket and that it's not still listening for connections before it deletes the file. It also provides a way to override all
.listen() methods so it does this automatically.
$ npm install cleansocket
const cleansocket = require'cleansocket'const net = require'net'const server = netcreateServersocketpipesocketcleansocket'/tmp/echo.sock'// if the file was unable to be removed for some reason, there would// be an error. Otherwise the original filename is returnedserverlistensocketfile
You can also globally hijack all
require'cleansocket/listen'const net = require'net'const server = httpcreateServerserveron'request'reqpiperes// will call `cleansocket` before trying to listen. Add an `error`// listener to server to catch and deal with any errorsserverlisten'/tmp/http-echo.sock'
Emitted if the file exists and is not a socket. The following properties are added to the error in addition to the standard ones:
stats: An fs.Stats object.
filename: Name of the file
Emitted when the file is a socket, but it is still accepting connections.
