I am trying to develop a simple game using nw.js (node.js + chromium page).

I'm making desktop application with NW.js(node-webkit)

Based on this topic google chrome console, print image, print image I am trying to display image to console.

As suggested on the topic above, command below works nicely:

Simple question about versioning numbers related to NW.js.

Why NW.js major version is still 0?

In Windows 10 the taskbar is not showing my custom-made icon. I am using the latest (at the moment of writing) 0.51.1 version of nw.js and the taskbar icon always defaults doesn't matter what I am doing. Even though the .exe icon is changing on the build and behaves as expected. Have anyone managed to solve this issue? I read almost all issues log on this topic on the official nw.js Github page but it doesn't help and seems like the issue still happens for some users.

here is my package.json file

I am trying to use module.exports() to create a new module in my NW.js application.

I have two files that I am using:

Index.js

In my NW.js app, I store some data in the Local Storage. Now I want to delete the app and surely the Local Storage data as well. I move the app to the trash and clean it up. Also, I delete cache information related to the app located in /Users//Library/Caches/.

But unfortunately, all this doesn't help. After building a new copy of the app and shipping it to the macOS Application folder the Local Storage data restores from somewhere like it never has been deleted at all. All the data still here.

The question is how to delete all the stored data and where does it sit? Or at least from where to read about it because I couldn't find information in the nw.js official docs. Thank you.

I have a project that uses NW.js in conjunction with Vue.js. The problem is that I can't include systeminformation module to the Vue.js because according to the documentation (see the core concept section) this lib doesn't work from inside the chromium but only on a server-side. How to include this lib in nw.js to make it available globally so I can use it from inside the vue code?

I've been using a solution that seemed to work but recently I figured out that it isn't. What I've been doing - I included script right in the ./public/index.html and it works on dev but not on the build. When I build the app and move it to another place it just can't find the path to the systeminformation package.
