Steps to reproduce the problem:
I want to use chrome as a node js debugger/"ide". node --inspect works fine but when i want to map files with the local file system in windows for live editing...I got problems with the workspace path mappings / breakpoints, etc. Im using NodeJS v7.4

What is the expected behavior?
I made a proxy workaround to remap the source urls and replace the directory separators.

My process runs form a subdirectory... thats why i made this: path.resolve(__dirname+'/../..');

This code connects to the standard 5858 debugger ws port and listens on 5859... so you have to change the link when connecting devtools. Example: chrome-devtools://devtools/bundled/inspector.html?experiments=true&v8only=true&ws=127.0.0.1:5859/11212484-27c8-4a50-98c0-e298d8b9942c

If there is a better solution, pls tell me.

this works fine from a seperate process::

var WebSocket = require('ws');
var WebSocketServer = WebSocket.Server;
var path = require('path');
wss = new WebSocketServer({ port: 5859 });
wss.on('connection', function connection(ws) {
ws.dbgclient = new WebSocket('ws://localhost:5858' + ws.upgradeReq.url);
console.log('Debug proxy connection: ' + ws.upgradeReq.url);
ws.dbgclient.on('message', function(message) {
//From app
var msg = JSON.parse(message);;
if (msg.method=='Debugger.scriptParsed') {
var abspath=path.resolve(__dirname+'/../..');
if (msg.params.url.indexOf(abspath)==0) {
msg.params.url=msg.params.url.substring(abspath.length).replace(/\/g, '/');
}
}
ws.send(JSON.stringify(msg));
});
ws.dbgclient.on('close', function() {
console.log('Host connection closed');
});
ws.on('message', function(message) {
//From chrome
var msg = JSON.parse(message);
if (msg.method=='Debugger.setBreakpointByUrl') {
msg.params.url=(path.resolve(__dirname+'/../../')+msg.params.url).replace(///g, '\')
}
ws.dbgclient.send(JSON.stringify(msg));
});
ws.on('close', function() {
ws.dbgclient.close();
console.log('Proxy connection closed')
})
});

What went wrong?
I got problems with the workspace path mappings / breakpoints, etc. 

Did this work before? No
