Callback is called immediately when opening a webpage in chrome with chrome already open

[sgen]

Reproduce by opening chrome and then calling opn('http://google.com/', function() { console.log('closed'); });

The callback is immediately called and chrome remains open.

What Node.js and OS version are you on?

Works correctly for me on OS

If you're on Windows, please read the docs:

On Windows you have to explicitly specify an app for it to be able to wait.

[sgen]

node version: 0.12.7
Im running ubuntu 15.04

Works correctly for me on that exact same setup.

Im running chrome 45.0.2454.101 (Official Build) (64-bit).

Tried reinstalling chrome and Im still having the same issue.

Just to be clear: I open a single chrome window, run 'node index.js' (https://gist.github.com/sgen/3538b746bfa23199bf91).

Chrome opens a new tab in the same window and 'closed' is immediately printed to the terminal.

I believe, I just can't reproduce with the exact same setup and code.

Are you sure you're on the latest opn version?

[sgen]

Yes I am (3.0.2)

This happens for me as well. Callback is immediate.

Chrome 45.0.2454.101 m (x86), v3.0.2 of opn on Windows 7 x64

Code looks like:

opn('http://www.google.com'`, {
  app: 'Chrome',
}, function(error) {
  console.log('Error:', error);
});

Error is undefined

This is obviously not an answer as I am just trying to give more information to people to hopefully help. That being said this also doesn't seem to be an issue with opn itself and, while useful for people to find, should probably be closed.

Same issue in C#

FWIW, the --user-data-dir flag is supposed to solve this, but I couldn't get that to work on any language, so if anyone is able to get this to work, please post for others to see (or if relatively trivial, create a pull for @sindresorhus).

Bumping this as it's still happening. Any developments or at least ways to circumvent this?

In my case, I'm trying to open an Excel file. Whenever I open the file while another file is open, it will call the callback immediately and not wait for the file to be closed. I want to detect when the file is closed so that I can read it afterwards. I created a repo for this issue with excel files if anyone interested in reproducing it: https://github.com/hyalkaf/nodejs-opening-multiple-excel-file-problem-opn

Hi,
I'm struggeling with an similar issue. I want to open a ".MSG"-File with the open-Library.

Sadly the callback is called immedietly after the window opened if an instance of outlook is already running. This also initially occurred for excel files. I then set the app property ("EXCEL") which solved the problem.

I think the problem is with that "/f" argument which is used to open an msg file. But without that argument I'm not able to open my ".MSG" file.

Versions:
open - 6.2.0

Code:
open(program.filepath, {wait: true, app:["OUTLOOK", "/f"] }).then(() => { // Gets called directly after the window opens (if no outlook instance was running) });
