bugger's Introduction

bugger

Warning: Experimental

bugger provides Chrome Devtools bindings for node. It integrates tightly with Chrome which means two things:

It attempts to fully support the usual Devtools experience, including workspaces and profiling tools.
It may break at any moment because Chrome moves fast.

Installation

npm install -g bugger

Usage

Start the script process

Start example/alive.js in debug mode:

bugger example/alive.js

Pass parameters to the script:

# This will be interpreted as a port paramter for alive.js
bugger example/alive.js --port=3000
# This will be interpreted as a port paramter for bugger itself
bugger --port=3000 example/alive.js

Pass V8 options (or advanced node options):

node --trace_gc $(which bugger) example/alive.js

Open the devtools

The correct URL will be written to the output. It should look similar to this:

chrome-devtools://devtools/bundled/devtools.html?ws=127.0.0.1:8058/websocket

You can also open chrome://inspect if you started Chrome with --remote-debugging-targets=localhost:8058. The process should pop up on that page almost immediately.

Options:

-v, --version: Print version information
-h, --help: Show usage help
-p, --port: The devtools protocol port to use, default: 8058
-b, --brk: Pause on the first line of the script

Examples:

Using bugger with popular frameworks is easy and it is a lot faster then using node-inspector.

Jest:

Run node with bugger and jest:

node --harmony $(which bugger) ./node_modules/jest-cli/bin/jest.js --runInBand

A chrome devtools URL will appear in console, just copy and paste it into chrome.

Mocha:

Run bugger it with _mocha:

bugger --brk $(which _mocha)

A chrome devtools URL will appear in console, just copy and paste it into chrome.

Features

Console Tab

Basic support for console API
Evalute expressions in the console
Fully featured repl when not paused (including require)
Parts of the Command Line API supported

Sources Tab

Step-by-step debugging
Variable introspection
Live edit the running JavaScript code and persist it using workspaces (really just a Devtools feature)
Break on [uncaught] exception
Uses existing source maps (e.g. created via babel --source-maps or coffee --map)
Forked modules show up as worker threads. This includes modules forked via cluster.

Known Issues

For babel-core/register and coffee-script/register, editing the files doesn't work #48

Network Tab

Monitor outgoing http(s) requests your script does
Timing of requests, including connect times etc.

Timeline Tab

GC events
Basic heap usage graphs

Known Issues

The timeline tab doesn't do anything useful right now. In future it should show (#47):
- console.{time, timeEnd, timeStamp}
- Network request
- Heap usage over time
- Profiling data

Profiles Tab

Heap snapshots
CPU profiles
Track heap allocations
Inspect heap objects in the console via $0..$4

Kudos to...

...the original projects

bugger was heavily inspired by node-inspector and nodebug.

bugger's Issues

ECONNREFUSED on Ubuntu Server 14 - Accessing as root

Tried running bugger with the default command bugger myScript.js and I'm getting the ECONNREFUSED issue. Have tried using the webhost/port command line switches but to no avail.

I'm logged in as root so I wouldn't have thought there were any permissions issues?

Any thoughts?

Mirroring thrown objects and errors

Looking at the kind of results Chrome gives when an error is thrown

{ result: 
   { type: 'object',
     objectId: '{"injectedScriptId":1,"id":5}',
     subtype: 'error',
     className: 'ReferenceError',
     description: 'ReferenceError: foobar is not defined\n    at <anonymous>:1:1\n    at Object.InjectedScript._evaluateOn (<anonymous>:878:140)\n    at Object.InjectedScript._evaluateAndWrap (<anonymous>:811:34)\n    at Object.InjectedScript.evaluate (<anonymous>:667:21)' },
  wasThrown: true,
  exceptionDetails: 
   { text: 'Uncaught ReferenceError: foobar is not defined',
     url: '',
     line: 1,
     column: 0,
     stackTrace: [ [Object], [Object], [Object], [Object] ] } }

Versus the simplistic value bugger gives

{ result: { type: 'string', value: 'foobar is not defined' },
  wasThrown: true,
  exceptionDetails: { text: 'foobar is not defined' } }

Seems like mirroring the object and providing error.stack as a description would be preferable here?

not able to make it work

Hi Jan,

I'm kind of unable to make it work...
With node 0.10.22 I get an exception.
With node 0.11.8 I get:

C:\a\www\x>bugger x.js
Warning: Native modules not compiled.  XOR performance will be degraded.
Warning: Native modules not compiled.  UTF-8 validation disabled.

(this is from WS unable to compile the native module, which is optional)

... but when I open chrome-devtools://devtools/bundled/devtools.html?ws=127.0.0.1:8058/websocket in chrome, it seems to be connected ('cause I get a websocket_closed message if I kill the bugger process), but does not show any controls or anything... Just a blank page.

the frontend url mentioned in README.md (chrome-devtools://devtools/devtools.html?ws=127.0.0.1:8058/websocket) seems to just keep loading forever

A more useful timeline tab

Timer events (e.g. setTimeout)
console.{time, timeEnd, timeStamp} support
Network requests
Profiling data that is actually visible
Heap usage reporting tied to events, not to a timer

Segmentation fault: 11

When trying to debug a coffeescript file, the bugger process exits with the message Segmentation fault: 11.

This can happen at any point in the debugged file, exactly as I "step into" a command. Does not have to repeat at the same point. One time it can go through without problems and the next time it crashes.

Mention debug protocol trace flag in docs

--trace_debug_json logs all debug requests & responses from inside the v8 debug interface.

Profile tab: cpu profile chart view colors unreadable

Hey Jan,

I just tried out the latest version and checked the cpu profiler with the chart view. unfortunately the colors are really bad and the text colors are almost the same as the background colors + they seem to have some text-shadow.

In the chrome dev tools this is not the case. I checked the code but couldn't find where they are defined.

Is it possible to stick to the chrome color scheme?

Copy to cUrl etc. not working in network tab

Chrome is not trusting devtools by default (they really have some trust issues with their own scripts). In this case it prevents copy to clipboard to work, there is no fallback (like writing the data to console instead), so the context menu in the Network tab is pretty useless right now.

CPU profiles show no timing information

Reproduce: Hit "Collect JavaScript CPU Profile", do stuff, stop profiling. Be annoyed because nothing useful shows up.

The error console of the devtools shows something like this:

Uncaught TypeError: Cannot read property 'id' of undefined inspector.js:7457
Uncaught TypeError: Object 33025 has no method 'split' inspector.js:3539
43
Uncaught TypeError: Cannot read property 'id' of undefined

Frequent segmentation faults

If Debugger.enable is sent before Runtime.enable, everything sort of just, breaks.

Not a deal breaker tho, just need to ensure the debugger is enabled before the runtime.

Add Command Line API

See: https://developers.google.com/web/tools/chrome-devtools/debug/command-line/command-line-reference?hl=en

v2 Feature Parity

Known issues

Reconnecting in paused state does not send the backtrace correctly
The timeline tab doesn't do anything useful right now (e.g. console.{time, timeEnd, timeStamp}, network request and heap usage reporting aren't working). Profiling data is collected but not really displayed. #47
~~For babel-core/register and coffee-script/register, editing the files doesn't work (potentially a won't fix)~~ #48
Break event handling doesn't report on the breakpoints involved
Impossible to pass V8 flags (and other options) into CLI tool

Build fails when adding bugger as a dependency

When i try to run a build on Travis CI, i always get an error as soon as i add bugger 2.3.0 to my package.json.

I am using node v6.7 with npm v3.10.3 on a linux machine (default Travis CI environment for node js projects).

TypeError: Path must be a string

I am running bugger app.js, then open the printed link into Chrome, Chrome then says "Debugging connection terminated, reason: websocket_closed" and I then see the following error in my terminal:

I tried the following, but no luck:

bugger ./app.js
bugger "./app.js"

chrome 29.0.1547.57, chrome-devtools:// spins forever

bugger has stopped working for me. the chrome-devtools tab loading indicator spins forever.

Cannot run any console commands when in breakpoint

No matter what console command I run, I get this error message:

Uncaught ReferenceError
message: "__buggerCLI is not defined"
stack: (...)
get stack: ()
set stack: ()

I am running jest tests with the following command:

node --harmony $(which bugger) ./node_modules/jest-cli/bin/jest.js --runInBand

Also tried to use this command:

bugger ./node_modules/jest-cli/bin/jest.js  #--runInBand

How can I use this with Babel?

Hey there. I'm a non javascript developer that recently inherited a js project. Bugger was recommended by the previous developer. I can run my project's es6 test suite by doing bugger ./node_modules/.bin/_mocha. And it seems like the transpilation happens on the fly just fine. But I can't figure out how to run an individual file. I can do babel-node test/load_test.js, but bugger test/load_test.js obviously doesn't work. Is there a way to do something like bugger --babel-node test/load_test.js? I don't see anything along these lines in the readme.

Sorry if opening a ticket is inappropriate for this question :)

Recent Chrome updates in mac broke profiler

I used to use this tool to profile memory leaks with my running node apps, but this new update in Chrome (Mac) broke it. I am using Version 32.0.1700.77

Can't even install this?

NPM is telling me that node-gyp rebuild fails for the v8-profiler package.

Are there plans to fix this?

Unintentional license?

I see that package.json is essentially default generated with even author name missing, would you mind explicitly stating the license (license.md or similar)?

It came up a lot with amok when it was becoming semi-popular and by proxy it will be brought up here when i release 2.0 with node support via bugger.

How to run bugger with Mocha?

Bugger has been a great experience with Jest, but any ideas on how to run mocha tests with it?

Allow restarting the process when it is done running

Right now after the process ended (e.g. it just crashed or hit end of logic) bugger needs to be killed or is pretty useless. There should be a :reload command in the terminal (and :help, for that matter). This command should also work anytime.

Environment or Configuration Error?

Trying to run bugger against a short test file and am immediately getting the following error on Windows 7, node v0.10.10:

Any ideas?

Q: source tab - file - "reveal in navigator" menu item possible to have?

Hi Jan,

in the chrome dev tools source tab, when a file is open one can right click on the file's tab and select "reveal in navigator" which will focus on the file.

This functionality is really nice to have.
E.g files tend to have common names like "index.js" or "utils.js". When profiling one can click at the file code line, which will open the file the source tab. The problem is that one doesn't know where the file is located.

Is it possible to get this functionality to the source panel?

Make url point to the entry script

Hey @jkrems.

Minor nit issue, /json/list returns file://(...)/node_modules/bugger/lib/io-thread/index.js as the url. Would make more sense if it returned the entry script?

Watch loaded files & recompile (--watch options)

When started with --watch, bugger should watch the files it loaded (source files for coffee-script) and recompile them when they change (hot code reloading).

Unable to pass arguments to Node.js

I'd like to pass arguments to node, such as --expose-gc (which might make a nice default; we are debugging after all!)

$ bugger --bugger-arg app.js -- --script-arg

As it stands, providing arguments which bugger doesn't understand prevents it from executing. Perhaps unrecognized arguments could be passed along to node?

double attributes

Hey, first of all: Awesome tool!!!
Really convenient to use, way better then node inspector.

When I console.log variables, all their attributes are shown double.
I'm using node v 0.10.26

If you need more information, just ask.

Thanks

process.dlopen on Windows

I get this error when trying to use this under Windows 7:

[bugger] Debugging flk.coffee
[bugger] chrome-devtools://devtools/bundled/devtools.html?ws=127.0.0.1:8058/websocket&toolbarColor=rgba(230,230,230,1)&textColor=rgba(0,0,0,1)

module.js:485
process.dlopen(filename, module.exports);
^
Error: %1 is not a valid Win32 application.

TAP version 13
# spawn
stdout: 'chrome-devtools://devtools/bundled/inspector.html?ws=127.0.0.1:4000/websocket'
stdout: 'console log'
RDBG 38874: connect
RDBG 38874: request { id: 0, method: 'Console.enable', params: {} }
RDBG 38874: message { method: 'Debugger.scriptParsed',
  params: 
   { scriptId: '236',
     url: 'file:///usr/local/lib/node_modules/bugger/lib/agents/console/index.js',
     lineCount: 103,
     sourceOffset: { line: 0, column: 0 },
     context: null,
     evalContext: null } }
RDBG 38874: response { id: 0, method: 'Console.enable', params: {} }, { id: 0, error: null }

So there are two things going "wrong" here. Or they are at-least behaving differently from the spec.

I have not called Debugger.enable, yet I am getting scriptParsed notifications.
I am not getting Console.messageAdded notifications for the console messages that occurred before Console.enable is called.

Mirroring dates, regexes

A few more instances of description field "lacking" compared to what chrome reports

For example, regexes

{ type: 'object',
  objectId: '{"injectedScriptId":1,"id":1}',
  subtype: 'regexp',
  className: 'RegExp',
  description: '/asd/' }

{ type: 'object',
  objectId: 'mirror:undefined:4',
  className: 'RegExp',
  description: 'RegExp' }

Dates are the same story

{ type: 'object',
  objectId: '{"injectedScriptId":1,"id":3}',
  subtype: 'date',
  className: 'Date',
  description: 'Mon Mar 21 2016 14:08:10 GMT+0800 (PHT)' }

{ type: 'object',
  objectId: 'mirror:undefined:4',
  className: 'Date',
  description: 'Date' }

The subtype field seems to be missing for quite a few of the types too, like Map, Symbol.
