I'm trying for a while now to create a PWA in Oracle APEX by following some instructions on http://vmorneau.me/apex-pwa-part4/, but I'm having no luck in certain parts.
I've installed the demo to test it and see what's wrong, but I'm having the same issues with the demo app, namely some important files not being detected/found when I run it. I thought I had configured something wrong previously, but this time it was supposed to work properly.
Example, I have the app.js inside the js directory in Apex:
When I run the app, I get these messages:
I tried checking the file path the same way I tried to see if the manifest.json file was in the proper root folder, and it couldn't be found:
This looks like a common problem I see on the forums, that doesn't relate to the PWA concept. You'll probably find the same thing if you tried to refer to static files loaded into the workspace.
See Morten's example regarding a fixing the configuration

Or placed your files in the middle tier, using /i/ (or preferrably a custom location /c/)

I am trying to create the basic scene but nothing is loading on my HTML page. I don't know where to get the three.js file that I need to place inside my js folder before I can reference it as instructed on the docs page ().
Please can someone explain how I can import this file and add it into my js folder?
It would be helpful if you could share some code to judge if this is an internal problem.
First of all, if you make references to local files, you'll need to run things locally running a local server (for instance I run python -m http.server, then access my files in the browser from localhost:8000).
The other problem could be that your version of three.js or three.min.js is not the good one, you can actually get them from the github build folder, and place them in the same repo as your html file, to be able to import them (<script type="text/javascript" src="three.min.js"></script>).
Finally, you could also see what's going wrong in your console if you work on Firefox for instance, it might help you to solve your error.
I've build a project with pure reactJS using create-react-app and I successfully uploaded the app to my server but unfortunately I've lost my laptop and all of my data :( but my project working on the site my question is:
Is it possible to get my project back again to development mode through existing files?
You may be able to use https://github.com/1egoman/debundle to un-bundle the index.js file (in the case of create-react-app, Webpack is the bundler). If the bundled file was built in production mode, you may need to use something like https://www.npmjs.com/package/unuglify-js to get it back in somewhat readable order.
Sorry to point you to libraries which may or may not work, but the truth is that you may be better starting from scratch--the real knowledge in your mind, not in the source code. You may be able to throw in some improvements the second time around... look at the bright side!
solution in here: Can I use a sourcemap and bundle file to retrieve original react code
THIS IS 90% fix.
Publish the APP so you can access it through browser (e.g. NETLIFY, can publish by accessing your Git repo) -> open the published project in the browser -> then inside the browser press ctrl + shift + i (chrome and pc).
This gives you access to developer tools.
Find: SOURCES TAB
on left hand side you will see folder structure -> click into STATIC
Now you can see all CONTENT inside JS files and CSS by clicking on them.
You can now either copy and paste them into you IDE or download them by right clicking them and Save As.
I'm new to both openFrameworks and this compiler called Emscripten.
After struggling for a few days, I was able to compile my openFrameworks/C++ code into js but Emscripten gives me an html file with a lot of junk included (For example, there is a header and footer -
http://openframeworks.cc/setup/emscripten/)
I'm trying to host the video/animation itself like it is on this page (http://www.syedrezaali.com/#/great-scott/) but I have no idea how to go about it. Can anyone help me out?
Thank you
If you follow OF's guidelines Emscripten generates not only the html file but also some other files (I think it's 4 files in total). You need to copy all of those into your site, then link to the html file.
Notice that while developing you can use
emrun --browser chrome bin/yourSample.html
To open the file, but you cannot just open the .html file (not sure why). See this guidelines as well, which are linked in the OF tutorial.
Update
I haven't tested this, but it looks like OF loads a site template. See this makefile for emscripten, you may specify your own via PROJECT_EMSCRIPTEN_TEMPLATE or you could just change the template OF uses.
I've done research and see this is a recognized issue. I guess my question will be: Is there a solution in Eclipse Mars or in Neon? Another plugin for JavaScript Content Assist?
I'm running Eclipse Mars and have a project with Java and JavaScript (uses ScriptEngineManager). JavaDoc/AutoComplete is working in Java but not in JS files. It Was working but then just stopped. I've restarted, rebooted, refreshed, rebuilt. No joy. The error reported is :
An exception occurred while getting the JSDoc. See log for details.
(in the log: ) file.js [in [in ...Workspace\.metadata\.plugins\org.eclipse.wst.jsdt.core\libraries\system.js]] does not exist
I deleted and re-defined the workspace. No joy. Mouseover the keyword Array and it does show system.jsArray with ECMA info. But mouseover String and it shows src/docs/jsString. "src/docs" is a path in my project.
I'm thinking it's just looking in the wrong place for the docs but I don't know where to set that. I've read that there is a bug where auto complete only works within a file. This seems to be consistent where it's still looking within the current file for the definition of everything.
I can get String to refer back to system.jsString if I add an invalid function. But if I fix the function it goes back to looking in my src/docs. Go figure.
Maybe the project structure is wrong (this is FOSS I got from Github). In the root of the project there are src/foo folders with packages and .java source, a reference to the JRE System Library, a couple .jars, and another src folder with src/docs/java with .java files and src/docs/js with .js files. Do I need to change the folder type of src or do something else to it so that it's recognized as a code folder? Right now it's in the project explorer with a common "folder" icon, not like one of the package source folders.
Do I need Neon? Do I need another IDE?
This suggestion to update the .project didn't help.
I'm going to try the package "Eclipse IDE for JavaScript and Web Developers" but I dont know if that will help with this Java/JS hybrid project. I'm also going to try Atom.
Thanks.
I have a few files called "helpers.scss", "helpers.js" and "consolerules.js" that I use in every one of my projects. When I'm working on a project I'm modifying one of the files, for example I will add a function for replacing all strings within a strings into "helpers.js" but then when I open my other project I don't have that function.
Or I will add a helper css class in helpers.scss in the other project and I don't have it in the other projects.
What is the best way so I can always keep them in sync when I edit them in one of the projects? I was thinking of bower, gists, git, dropbox, google drive or something like that ...
I used two ways to handle these:
Get a CDN like server
Have a single version of those files and place them on a server. For example you could have URLs such as:
https://cdn.example.com/css/helpers.css
https://cdn.example.com/js/helpers.js
If you want to support versions (maybe you should?), you can add that to the filename:
https://cdn.example.com/css/helpers-1.3.css
https://cdn.example.com/js/helpers-1.2.js
Or to the path if you view all your files as having one common version:
https://cdn.example.com/1.2/css/helpers.css
https://cdn.example.com/1.2/js/helpers.js
Versioning is useful if you want to test a website with the newest version before using that version on your live site.
This is most certainly the easiest way if you can implement it that way. Now all your other websites will use those URLs instead of local versions of the files:
<link type="text/stylesheet" href="https://cdn.example.com/1.2/css/helpers.css"/>
Pull those files at build time
Depending on how you organize your websites (it is really not clear from your questions) and assuming you have folders on your machine with the original source, you can bring in those files as required with a script that you run before you upload your sites.
In my case, I like to do that in three steps:
I write the files
I copy the files to a .../build/... folder
I send the .../build/... folder to my test or production server
One reason for this is to generate a build folder that includes exactly what you want, verify it, then send it to your server. That verification happens only when you write your script. Once done, it should not require any additional work.
So... one reason to get such a script is that I can compile my files. For example, if you write PHP code, the servers only need the most compressed version of your code (unless you are debugging and need to find line numbers...) The script that generate the build folder could do:
for p in php/*.php
do
php -w $p build/$p
done
Now your PHP code on your server may be something like 20% smaller.
Similarly, you could copy your helper.css file as in:
cp ../helper-project/css/helper.css build/public_html/css/.
This copies the helpers.css file to your build folder. Since it grabs that file from your unique ../helper-project folder, you will always end up with the latest.
And instead of a simple cp command, you could also minimize that file at the same time:
cleancss --remove-empty ../helper-project/css/helper.css > build/public_html/css/.
The only problem here is that if you make changes to the helper-project, it won't automatically update all the projects. You still have to do in each project and run the script(s) that generate the build folder and copy that to your servers. Yet, I find that to be a practical way of doing things because that way I know when I do the update and I can test the resulting website(s) before going to production and once I update a production site, I can verify that it's still all working just fine.
You can do this with git (or any modern VCS); I assume you are using some sort of VCS for your code.
If you have a project being managed in git, you can even add multiple remotes, such that you can pull in code from multiple sources.
If you are using a VCS like git, then it is just a matter of doing a git pull <remote ref> <branch ref> whenever you want to sync up.
Otherwise, the comments to your question offer some alternatives.
