I am trying to set up an ipad app that relies on using javascript for part of its functionality. I need to have the files in a folder named javascript to have some code I am using work properly.
I have created a symlink from my javascript files into the folder I set up and have included the files in the copy bundle resources in the appropriate build phase.
My issue is that under that section xcode says the files are in javascript/...
So in theory everything should be in the right folder. However, in my code I am using
[NSBundle mainBundle] pathForResource: pathName ofType:nil]]
and it returns nil when I set the path to the file in the file path and name listed in xCode.
Is there something I am not doing right to the app to have to proper file path names?
I am using the ipad simulator and xCode 5
For files that are in a subdirectory of your app bundle, you want to use the method pathsForResourcesOfType:inDirectory:

From the Vue CLI https://cli.vuejs.org/guide/deployment.html, it stated that the dist directory is meant to be served by an HTTP server. But why can't I preview it from the index.html? Cause my understanding is that Vue is just a front end JavaScript framework, so one should be able to preview it from any browser. If am to create a simple vue project using a cdn, it can be directly previewed on the browser. But this is not the case for the vue project created through the CLI. Can someone explain this.
Take a look into the Chrome Dev Tools. You will see a couple of errors similar to those:
As you can see, there are a bunch of files that fail to be imported. This is because these files are not imported using a relative file path, but an absolute one (starting from root, as visible by the prepended / in all files in the index.html).
If you run a local server from the dist directory root will resolve to this directory, allowing the files to be imported properly and your site to be visible in the browser.
However if you simply open the index.html file in your browser, / will resolve to the root of your operating system, which does not contain the files. If you were to copy all those files into the root of your OS, so that the paths would resolve successfully, you would not need a server to view your Vue application.
CLI projects are built with the use on a server in mind. The idea is to just be able to deploy the files in the dist directory to a server and have a working Vue application.
Just to add to a great answer from #aside.
You can use a publicPath configuration option of Vue CLI and set it to '' or ./ - this should be enough to make it work from file system
The value can also be set to an empty string ('') or a relative path (./) so that all assets are linked using relative paths. This allows the built bundle to be deployed under any public path, or used in a file system based environment like a Cordova hybrid app.
vue.config.js
module.exports = {
publicPath: ''
}
I know what these files contain like build contains the minified file which is minified from src file. I need to know how browser works with it. I haven't uploaded my build file to hosting service yet my website got rendered. In the website, <script> SRC was linked to build but there was no build uploaded but a build was created automatically. this behaviour was observed in svelte. But I hope all framework does the same.
As far as I know, build tools like webpack, parcel, ...etc., use BUILD or DIST (Of course you can change it however you want) folder to store production ready build files of the project.
Files in PUBLIC are just copy & pasted to the build/dist folder when build process is finished. You can store index html, images, fonts, favicon or other static text files in there. They are not processed by build tools.
SRC folder is just for storing the whole project's unminified source code.
Most frameworks use 'build/dist - src - public' structure while frameworks like next.js uses root for storing project source code by default.
From the Vercel documentation found here https://vercel.com/docs/build-step "Vercel tries to automatically detect the frontend framework you’re using for your project and configure the project settings for you. If you’d like to override the settings or specify a different framework, you can do so from the Build & Development Settings section." So Vercel did automatically make a build folder for you. This is ok, because you should always use npm run build to create your build folder and point your hosting to use this folder for production.
I am currently creating a Cordova app to save files and read files. I ahve successfully managed to code it up so that it reads a file from the device (or creates it if it does not exist) and then write to that file.
The problem I am having is that it is saving the file to the root of the device. I added in a getDirectory method to create a new directory under the root where the file can sit and this is working but ideally I would like to save the file within the www folder of my Cordova app. Is this possible? Also is there any way of making sure the user is unable to write to this file?
The www folder is in readonly mode. You can't write anything in it.
Cordova plugin file documentation explain this.
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)

i'm new to Mosync and i'm trying to create an HTML5/Javascript project. The IDE generates a main.cpp file and an index.html file.
The main.cpp file contains a reference for the index.html file; i've already tried creating a new html file inside the same folder where the generated index.html file is and changed the reference in the main.cpp file to call the file that i've just created but it gives me an error that says the file cannot be found.
I've even tried removing all the code in the generate index.html file and running it and the results still shows all the deleted code from the index.html file.
My question would be how do i add multiple html files when creating a MoSync project?
It should work to do what you are doing, this could be a bug. Can you provide some details about which version of MoSync you are using, and which platform?
You should be able to have any html file in the folder LocalFiles in a MoSync project, and then just pass the file name to showPage in main.cpp, just as you are doing.
Perhaps the project is not rebuild properly? Try to right-click on the project in Eclipse, then select Rebuild. Are you on iOS or Android? How do you transfer the app to the device?
As Mikael mentioned also, I think it is an IDE bug, I tried refreshing/rebuilding the project and it worked fine. Sometimes eclipse does not detect file changes that come from other editors so it ignores them.
