I am willing to make a portable app using HTML CSS JS and similar languages that doesn't need any installation and can be accessed via a browser.
The app should be able to access the file system and create, write and delete files.
The required files will be on the local machine.
I have tried
Applets but the performance is too inconsistent and depends on browsers.
I have also tried using electron but the end result needs installation (correct me if I am wrong)
I am open to all suggestions
Electron's apps can be portable. Copy the electron build resulted folder into a pendrive and execute the main .exe file from there. Everything should work

I'm very new to React-Native. I've moved from CoronaSDK. There, in CoronaSDK, there's a plugin that allows you to download and run external lua files or lua strings and run them.
I was wondering if there was a similar feature, whether internal or external, to allow for downloading and running Javascript(React) files and run them after app build?
I saw services like CodePush, that allows for full app updates deployment. However, I wanted to see if there was something similar to downloading and running individual files.
I have one code base for both Web and NodeWebkit (NW) application.
I use the following stack:
- React
- Hapi
- Sequelize
- Windows environment
Web version of the application uses MySQL, while NW uses Sqlite. It all works fine. I have config file that compiles application for what I need (web or NW).
The problem that I face now is how to deploy the NW application. Idea is to provide NW applicaiton to a client, where he will open it clicking the icon.
Since I use the Node for the NW version, and the application uses many modules which are stored in node_modules, I face a challenge how to pack it all up.
My idea is to make an Windows installer. User will click it and the installer will extract all files to the destination. And also make an icon on the user desktop to run it.
Problem is with the Windows file name limitation. Inside the node_modules, there are many subdirectories that simply violate the Windows limitation. I cant even copy the node_modules folder. I cant even delete it. Well sure I can copy it If I zip it... or remove manually long folders.
I have not yet started working on the installer, but I am thinking I will hit the wall with this approach.
Does anyone have an idea how to make this deployment?
How can I integrate NPM3 in NW?
My plan now is to make Windows installer. That windows installer will install normally application files. The node_modules will be zipped previously and placed inside the installer. Installer will then simply unzip it to the destionation folder.
I will post my progress here.
Some update here.
Main issue here was the depth of the node_modules. I have many modules in node_modules, and after some thinking I figured out there is a simple rule there. Some modules are server side modules, while other ones are used by react.
And since Webpack already creates a huge files in which all of the modules are already included, I simply do not need them at all.
So I have removed all front end side modules(babel modules, react-*), and left only server side (Hapi, sequelize...). Miracle happened, application run and was much faster at the startup.
I am going to use Inno setup to make a manifest file, and it should be good to go.
I am still not out of the danger zone, as developer might need a server side module, which has huge depth. But I will think about that if it happens.
More to follow...
actually in nodejs you can do the following:
1-Create another folder inside your project folder for example "server_modules"
2-In the created folder create another package.json file and install any modules needed for server out there
3-All these modules will be accessible as normal node_modules using require('module_name') and you can delete "server_modules" folder when you package your desktop version if you don't need it
Note: this approach used by some developers to achive micro services in nodejs but it is useful in your case
I have java project with html/js files. These files are packaged by maven and deployed to Java EE application server.
To modify one symbol I (theoretically) need to recompile, repackage and redeploy whole project. In practice change html/js in Intellij Idea project and copy them directly to application server manually.
May be Idea support automatically coping files on save action?
If you use IDEA Ultimate (paid) edition, it supports creating Run/Debug configurations for application servers.
This allows you to create, deploy your application and test/debug within IDEA, without building with Maven.
For example, if you use Tomcat:
Once you launch this configuration, you'll get a convenient redeploy button.
I'm working on a Windows Store App (JavaScript/HTML/CSS) that will be deployed directly to devices in our enterprise.
I want to keep the datasources (urls to Restful web APIs) as part of the configuration rather than built into the app itself so that I can set them during deployment (e.g. to set test urls and prod urls).
More generally I want to store text variables in config that is external to the app and can be pulled in by the app somehow.
I thought I could set some environment variables or something but Windows Store Apps can't read them it seems.
Any ideas?
You could certainly make an HTTP request from the app on startup to retrieve a configuration file, but that of course assumes connectivity which may or may not work in your scenario. For a Store-acquired app, this is really the only choice.
In your scenario, however, you'll be doing side-loading through a Powershell, correct? (This is implied in installing directly to devices.) In that case, the Powershell script is running in full trust and will have access to the file system during the process. This means that the script can easily deploy a configuration file into the app's local appdata folder, which the app then picks up when it runs. The app package should also contain a default configuration file that it copies into that appdata folder if such a file doesn't exist on startup.
The documentation for the add-appxpackage script that does the install is here: https://technet.microsoft.com/en-us/library/hh856048.aspx.
Another option you might be able to use is to build different versions of your packages for test and production deployment. It is possible to configure the build process in Visual Studio to selectively bring in different versions of a file depending on your build target (e.g. Debug or Release). I have a blog that describes this technique on http://www.kraigbrockschmidt.com/2014/02/25/differentiate-debug-release-builds-javascript/. This would allow you to package different versions of a configuration file into the package, which you'd then read from the package install location at runtime or copy to appdata if you wanted to make changes at runtime.
I mention this method for building different packages because it's something that doesn't need you to do anything other than change the build target. It accomplishes what you would do with #ifdef precompiler directives in other languages, which aren't available for JavaScript.
I've been working on an app which will feature a Timelinejs (open source js library) element on the client side. I copied the Timelinejs library into my public/javascripts/ directory of my app. Then I linked it in my html header. When I serve my app up locally everything works fine with the timeline. However, I noticed that when I deployed my app to Heroku it wasn't loading my timeline. Using chrome js console I discovered that it didn't find my files in the public/Javascripts/Timelinejs folder. Using the Heroku run bash command I discovered that none of my Timelinejs files were present in the file structure, although an empty Timelinejs directory was present. Is there any command or configuration I need to specify to get these files to my Heroku deployment?
Heroku has a readonly file system. The directory where you can write are ./tmp or ./log. You can't write inside the public folder.
That's because of how they manage their dynos and the way to scale them. If you want to store something, use the ./tmp or, recommended, a s3 bucket. (as I presume 'tmp' stands for 'temporary' :D)
