I am looking at porting an existing application to phonegap build, however as my application is a multi-page application with pages split in different locations and a resource loading mechanism which loads files from different places.
So I basically want to be able to get my applications root directory up front and then use that when initilizing the application. Then it does the rest itself once it knows the root directory and has a file managing class which will build the file paths based off this root value.
I did notice this question:
Getting application directory in phone gap
However it does not seem to act the same on each platform, and I need this to be consistent. So is there a simple and consistent way to get a string representation of the applications root directory?
In my case after asking the guys at phonegap, they say that you dont really need to do any of this can just use location.hostname so am looking at using that approach for now, the main reason for asking this is because in trigger.io I would be using tools.getUrl. So I assumed in Phonegap I would need to do something similar.

I would like to know how to make my Next.js file work on every computer without having to reinstall all my modules.
Basically, I have my folder, nextjs-node, containing the following folders:
components
lib
public
node_modules
page style
package.json
I'd like to know if there is something I could do to create an icon on which I can just click to launch my website without have to go to the folder in my terminal and type npm run dev .
As a heads up, stack overflow is more for asking specific questions rather than general project approaches, as a result this will most likely be flagged eventually.
However to answer your question:
So next just creates a framework for websites which means that what you want to do isn't quite possible however there are a couple of options here:
You want to have an executable that launches your platform as an electron app. An example could be done with: https://github.com/saltyshiomix/nextron
You can always just host this as a website, and users can use shortcuts to just link over to the site in a web browser.
You can make your site a progressive web app where the user can save your site locally (however you will still need to do option 2).
Let's say I have a HTML/JS application, which is on a website and runs without any server-side component (except the web server, of course). So it's basically just a bunch of .html, .css and .js files (and some others, like images or SQLite databases)
Someday, an user comes to me to ask me if I can make an offline version, so they can access the app when they are offline.
My first reaction would be to provide them all the files of the app in a .zip file or something, but this is not really good: it's not "clear" to an average user, and the files and code are apparent (which could be "dangerous" if the user edits or deletes them by accident).
So I was wondering: is there a kind of format that would makes me able to store the files of the app in a packaged file?
The file would be something like a .zip file, but when you click to the file, instead of opening up the archive, it opens the /index.html (or similar) which is inside.
So for the user, it would be similar to open an .exe or a single .html file, but still that's not a native app, as that's still a browser app.
Given that I know about:
Apache Cordova; but most of the time, I just use the browser functions, and I don't have a need to use advanced native functionalities;
UWP and PWA, but I don't know if it's exactly what I want (I imagine it as a mix of website and mobile app, but I'm surely wrong);
Open Web App (a standard from Mozilla), but based on what I've read about it, it seems deprecated and not used anymore. Plus, I don't really look forward to "certify" my app... I just want to package some files.
PWA I don't think is a solution to your problem as you wont be able to redistribute the code as an executable package.
UWP would be too Windows specific and might make you lose the platform independence that you already have since you are using plain HTML and JS, plus from what I understand you would need to distribute the app on Windows Store.
I believe packaging as an Electron app would be the best solution as you can provide executable files that can be executed in almost all platforms.
Electron would be the best solution for you. I had a client that first wanted to run app on php server and eventually they figured out they need it as a desktop app. It was easy to rewrite php stuff to node and package as Electron app. You have access to everything files, system etc. so you can do more if needed.
Another solution would be to just inline everything into a single html file.
Every time we release a new version of our software which is bundled using Browserify, we are finding that we need to ask our users to clear their cache using the regular methods of CTRL+F5 or diving into the browser settings. It is not ideal when there are a thousand or so users. We are trying to work out a way that we can perhaps get around this. I am open to all sorts of options.
Our project is ReactJS based, so runs in the browser and connects to back end services via a RESTful API. We do track which version is loaded and this is visible from within the console. Using the version number we can compare on two different machines that one user is running the latest version whereas someone else may not be.
The code is bundled into two separate files and I feel that this is where we should be looking.
You need to change the file name on each new release.
A hash of the file is an appropriate thing you could add.
Check out md5ify to add this to your project build.
If you implement this yourself, make sure to also load the correct filename in your index.html file.
Edit:
To automatically load the correct file you need to have a placeholder in your main html.
Then you need a manifest.json file that looks like following:
{
"main.js": "main.[HASH].js"
}
This has to be created automatically after the bundling.
Now you can replace the placeholder with correct asset by doing a lookup in the manifest file.
You either have to write your own scripts for this or use something like gulp together with browserify.
Another solution would be webpack
What are good practices about building a multiple page application using modern JS frameworks?
Multiple page application
In multiple page application we have multiple templates using some “template syntax” to provide us with backend data and AJAX (if needed) or advanced UX voodoo is often handled by jQuery.
Single page application
In single page application “backend data” is provided by AJAX requests and whole routing, frontend logic is handled by JS. We often use some JS framework like Angular or React and compile our sources with task runners/bundlers like webpack or gulp.
Hybrid application
But the most popular around the web seems to be hybrid app. What is typical build workflow while working with such an app? I could not find any tutorials or guides.
So to be specific. I imagine webapp where in which, each page has to be compiled and could share some resources. Every page has own JS routing like wizards or subcomponents. Data is loaded both during page load and AJAX.
For example my webapp would have 3 pages:
guest page - would provide website user with limited content and attract him to sign up
user - would provide signed website user with full content, resources would be extended guest content
admin - shares only styles and webapp “core”
Task Runners/Bundlers
For example in webpack is there a way to specify multiple entry and output points? Maybe the better way is to have multiple webpack/gulp configurations. In that case If I have a lot of pages I would have to write webpack/gulp configurations for every page even though some of them could be exactly the same. How to run that kind of build?
Sharing resources
Will browser load cached js bundle with the same hash like bundle.a2k4jn2.js within the same domain but different address? If so, how to specify such a behaviour in tools like webpack or gulp. I heard about CommonsChunkPlugin but not sure how to use it or even I’m looking at right direction.
Templates
What if I want to load some “backend” data not by AJAX but at the page loading. Of course every templating engine provides us with ability to write native code directly in html template like JSP or PHP. But what if some routing is handled by JS and “template tag” is not visible for page at initial loading i.e. template would not be compiled. Sometimes template engine in server and client could have the same special tag like Blade and Angular which can lead to conflicts.
Directory structure
I suppose that in hybrid app frontend and backend will be tightly coupled. Sharing JS in hybrid app could lead to very complicated imports (in es6 or html script tag). How to keep it simple.
Deploy
What about deploying an application? In java it’s easy because we just specify directories (compiled pages) in build tool (maven, gradle) which be copied to jar/war, but in PHP source code is not compiled how to keep “js source” away from production I could not imagine sensible resolution other than writing own batch/bash script
Summary
I have mentioned specific technologies and frameworks. But my question is about common approach to work with such an webapp rather than “how to do sth in that tool”. Although code examples would be greatly appreciated.
Their is a lot in this question, as a starting point you can define multiple entry points in webpack.
https://webpack.js.org/concepts/entry-points/
If you want to mix data loading between FE and BE then you really need to write an isomorphic JS application and use Node as your BE, otherwise you’ll end up writing everything twice in different languages and having once come across a project like that, trust me you really want to avoid that.
The other bit of this question on shared resources is best answered by WebPack’s bundle splitting which is made for what is being asked here
https://webpack.js.org/guides/code-splitting/
Not sure if I totally understand the question, but single-spa (yes it's redundant) is a tool that can be used to combine multiple apps (even if they are different frameworks) into one single page application. Link to the docs: https://single-spa.js.org/docs/getting-started-overview
Hi guys I'm looking to build an application that is a list of stores. One requirement is that for each store there is a special view of the store built in flash or javascript. This special view portion has been already built by someone else. It consists of a single HTML index file and a bunch of javascript/css in it.
So I think it would be very difficult to directly it as a part of the meteor app. What I want to do is to somehow have those special view portions be a separate entity from my meteor listing app. How can this be done? Will it need to be on different servers? Or can I just have two folders (one a meteor app folder, the other just those html+css+javascript/flash files) and have the meteor app have links point to the other folder? Any examples of meteor apps pointing to separate files but still function like a single webpage?
you can connect to another app by using DDP.connect() and it acts like REST API for websockets.
