V8 Debug Protocol

A simple v8 debug client implementation

Install

npm install --save v8-debug-protocol

How To Use

Create a client:

var Client = require('v8-debug-protocol')
 
// connect to remote port
var client = new Client(5858)
 
client.on('connect', function() {
  // nothing in this callback, just mark success
})

Send a continue request:

// after connected
client.continue(function(err, doneOrNot) {
 
});
 
// other continue
var step = 10
client.continue.in(step, function(err, doneOrNot) {})
client.continue.out(step, function(err, doneOrNot) {})
client.continue.next(step, function(err, doneOrNot) {})

Handle break event from remote debugger:

client.on('break', function(breakInfo) {
  console.log(breakInfo.script['some props'])
})

Get the scripts according to the script id

var ScriptManager = Client.ScriptManager;
 
client.on('break', function(breakInfo) {
  (new ScriptManager(client)).getScript(breakInfo.scripts.id, function(err, scriptContent) {
    console.log(scriptContent)
  })
})

Manage BreakPoints

list

 
var BreakPointManger = Client.BreakPointManger;
 
client.on('connect', function() {
  var bm = new BreakPointManager(client);
  bm.list()
    .then(function(breakpoints) {
      // all the brks
    })
});

clear one

bm.list()
  .then(function(breakpoints) {
    return breakpoints[0].clear()
  })

clear all

bm.clearAll()
  .then(fn, errFn)

create a new breakpoint

bm.createBreakpoint('script.js', 10, 'condition === true')
  .then(function(breakpoint) {
    breakpoint.should.be.instanceOf(BreakPoint) // :p
  })
