In Shiny, how can I link to an image or a css file that is not in the www folder of the app?
The situation is that I have several apps that share common code, but need to be treated as distinct apps. At the same time I want them to be styled similarly and therefore I want to link to images and css files that are not specific for the app.
The only way I know of linking to images and css files is to place them inside a folder called www in the app directory. But that means that each app will need a copy of the files, because each app has its own www folder.
When running an app I've noticed that Shiny itself links to files in a subfolder called shared/ but I have not yet found where that folder is located. Can I put my custom files there too?
Symlinking from the www folder to a common place comes to mind, but I'd rather not to have to do that. I'm also aware that I can include css styles inline in the html, but that's another thing I want to avoid.
After much searching I finally ran into addResourcePath.
It worked like a charm when added before the shinyApp call.

I always had a question about the problem of the folder of some site being very heavy, for example, let's assume that I'm using something similar to Bootstrap, in which case I would have several folders of Css/Js/Ajax/Vendor files, etc., but the HTML/PHP page would only import the css folder instead of using the others, having the other folders in the file would influence the loading of the site?
NO, a bulky project folder would not cause your website to load slower.
The way you perceive directories is quite different from the way they actually work. Directories are actually just pointers to where files are stored. The number of directories or files doesn't affect load speed, the server would only render what it needs by querying file paths (an HTML file, image, etc).
My less style sheets are located in my /public folder for now. I'm trying implement them on my meteor app but to no avail.
This is the error I get:
The stylesheets are located in the /less folder, which is inside the public folder, so the URL should be correct. By the way, all those files that are in the screenshot above are files that import dozens of other variables located deeper in the folder.
I also checked and I have the latest version of less installed. Any help would be appreciated.
The public folder isn't the right place to store the files. Files stored in a “public” folder are served to visitors. These are files like images, favicons, and the “robots.txt” file. So they get served 'as-is', not processed by LESS and served as CSS.
More about Meteor folder conventions.
After discussion in the comments, it seems something is not working right in your less compiler, the less file should not be in the public folder, as already mentioned, and you should not need to include it with a script tag. You can follow these steps to create a new app and test less and see if you can find a difference between this and your current app.
Create a new meteor project
meteor create test
Add less
cd test
meteor add less
Start your server
meteor
add a file sytles.less to the top level folder with this...
.fun {
color: red;
}
Update the test.html file to add the fun class to the text output...
<div class="fun"><p>You've pressed the button {{counter}} times.</p></div>
Load the page, the text should pick up the class and become red. No link to the styles.less file needed. You can try moving it around to different folders, it worked fine from client for me as well. Look around and see what else might be different.
If you still have issues, try providing more information on how the project is set up.
I am new to bootstrap. I downloaded a wrapbootstrap theme and is trying to include that in my website. In the downloaded theme, there are several folders under a folder called assets, like bootstrap, css, js, icons, img. Under bootstrap folder there are again subfolders called css, fonts and js. Can anyone please tell me where exactly in the project should i add these files? In case of a simple theme, I know we need to add the bootstrap css under Content folder and the bootstrap js under Scripts folder and we need to add it in BundleConfig.cs. But here, since there are different css files and js files, where can I include them?
Thanks in advance.
Where the files are located is really irrelevant so far as your application is concerned. The ~/Scripts and ~/Content folders are just a default convention that Visual Studio uses with the templates.
However, nothing is preventing you from moving them. When working with a template, you have one of two choices.
Leave the files as they are, and simply reference them, or include them into bundles in the paths they are located in.
Determine which CSS and JS files you need, and re-shuffle everything to suit your particular projects needs.
The first option makes it easier to upgrade the template in the future, while the second option makes your project files more coherent because they follow a similar structure.
At the end of the day though... it's all just a resource location for you web server to resolve. Do whatever makes sense for your project.
We got a wrap bootstrap theme call ace admin. We are trying to integrate the theme into meteorjs.
The structure of the ace admin files folder is:
assets
avatars
css
fonts
images
img
js
build
demo
files
lib
several javascript files here (*.js)
dist
avatars
css
fonts
images
img
js
By following the tutorial here
I moved all the static content such as images, fonts, etc to client folder, javascript related folders - (assets, build, dist and all the related content) to public folder.
The problem that I am facing it - Meteor is not loading the javascript files inside the public folder.
Could someone help? Thanks.
Edit:
Ok. Finally. Thanks to #Ethaan. After spending almost 2 days figuring out what the problem- its with the javascript loading dependencies. If anyone is facing similar problems - make sure you load all the dependencies first and then load other files.
Do everything in the link provided in the above url that I mentioned and then move all the js folder files to client.
You should know some things about meteor structure, You can read docs
/lib folder its where you put the code you want to share between server/client, code like Routes,Collectios or other code ho is available on server/client(if you put code which use "window" object you will have issues, since windows objects its undefined to the server.)
/publicfolder here is where you put the images, logos, fonts, etc (you get the idea)
/client folder here is where you put the code which will be available only to the client
/server here is where you put the code only available on the server
I recommend you to read the docs, this was just a quickly explanation.
edit I do not want to redirect pages, specific files etc. I would like to change the path where images, videos and other media are stored from the root source directory to the directory of my choosing. In this case c:/dev/prjfiles/prjname/public (c:/dev/prjfiles/prjname/ is my working directory) and i except when my html does img src="/pic.png" it will find the image in c:/dev/prjfiles/prjname/publi/pic.png. I need a working solution, i tried looking at how to set virtual directories and etc. I cant figure it out. Thus the bounty. I am generating the html, i am not writing asp:image runat="server" etc i am pulling data from a DB and outputing the html. The part that is still a WIP is the code that handles POST request. The html already exist but i cant have hundreds of files in site.com/here pollution my source directory (c:/dev/trunk/thisprj/thisprj/where my .aspx files are and i do not wish 500 .png/gif/jpg here)
I dont know how asp.net environments are usually set up. I am assuming i have a root path that is not available from the web, a bin/ where i may put my asp.net dll and a public where i stick in any files i want.
I would like to have my project files seperated from everything else. My JS, css and image files are in prjfiles/prjname/public with my sqlite db in prjfiles/prjname/ and extra binaries in prjfiles/prjname/bin.
The problem comes when i run my app and try to load an image. Such as /cssimg/error.png. My project does not find resource in my /public folder and i have no idea how to make it find them. How can i set my project up so it does?
NOTE: I set the working directory path so its at prjfiles/prjname/. In code i write ./bin/extrabin.exe and db.sqlite3 which access the files properly.

As #Murph suggests, your assumptions are incorrect.
IIS takes care of blocking HTTP access to any important files and folders like your *.aspx.cs, and *.cs in the App_Code, any DLLs, anything under the App_Data directory and the web.config.
Content files, such as *.html, *.css, *.js, .gif, .jpg, .png are all served in the normal manner.
In this way, there is no need for a "public" folder.

This is wrong assumption!
You have a root folder, which IS available in public. You set IIS or ASP.NEt Development Server to this folder.
(optional, but always needed) You have a web.config file in this root folder for configuration
You have a bin folder for your assemblies (each page or user control "include" compiles to a class)
(optional) You have App_Data as default folder for file-based DBs and/or other data files (say XML storage, ..)
(optional) You have an App_theme folder for styling and images. Read about ASP.NET themes.
(optional) You can add App_Code folder if you want to add classes to be compiled by the server.
You can create folders for scripts, etc...
Normally for complex logic, etc.. you create in a separate project outside the root and reference the result assembly in the bin folder.
Seriously, you cannot do ASP.NET work without an IDE or a manual. Visual Web Developer 2008 Express IDE is free and http://asp.net has tons of resources for getting started.
I don't know if I got the question right, but maybe you could try the <BASE> HTML tag.
HTML <base> Tag
"Specify a default URL and a default target for all links on a page"
There's a nice and simple example at W3Schools, check it out.
The negative side is that you need to put a <BASE> tag in each page you want.
It sounds like you should be able to create a virtual directory to do what you're asking -- but it's a very non-standard setup.
Keep in mind that IIS will prevent users from downloading DLLs and other project-level files, so you usually don't need to partition them off in a separate layer.
For example, just have a cssimg folder at the top level of your project, and skip the whole public folder thing.
I see where you're coming from. ASP.NET projects are set up a little differently from how you're treating them, but you can make them work like you want.
The root of an ASP.NET project IS publicly accessible. When you created your WebSite within Visual Studio, it created a default.aspx page right on the root. Are you hosting in IIS? If so, it's set up to serve up default.aspx by default. But I digress.
Here's how to make it work like you want (mostly):
Create a WebSite, then right-click the site and add a folder named "prjfiles". Right-click that folder and make another named "public". Create another subfolder of that one called "cssimg".
Now, if you want to use the image you mentioned, you'd reference it like this: "~/prjfiles/public/cssimg/error.png" (pathing starting with the root) or "./cssimg/error.png" if you're coming from a page in the public folder (relative pathing).
Really, though, you're doing too much work. Here's how to make it work with less effort:
Create your WebSite, right-click the project and add a folder called "cssimg".
Treat the root as you would the "public" folder- put your pages right there on the root or in subfolders, as needed. You can reference that same image file like this now: "./cssimg/error.png" (relative) or "~/cssimg/error.png" (start from root)
There's also another way to tell the engine where to look for resources, but it's for your css files. Inside the "head" tag, you can add a "style" element (with type="text/css") and inside that you can add something like this: #import '<%= ResolveUrl("~/prjfiles/public/cssimg/styles.css") %>';
Good luck!
If I correctly understood your problem, you're trying to find files which aren't physically stored on a filesystem folder, or stay on a different folder. You can deal with this problems by implementing a UrlRewrite mechanism.
I suggest you to read URL Rewriting in ASP.NET and, after, to take a look into this implementation: A Complete URL Rewriting Solution for ASP.NET 2.0.
If I understand all this correctly (please comment with any correction) right now all your files are together in the root directory and you use <img src="/img.png" /> and it works.
If this is the case, make another directory in the directory the images are in, say call that directory images and put the image files there. now use <img src="/images/img.png" />.
Done.
