I am trying to make a sign up activity on android and I am using a mysql database to store the data. On all the examples I have seen the http post goes to a ip address and then finds the php file. Can I just put the php file somewhere in the android app folder and access it from there, or do I have to find a host for it?
The php code, specially for tasks such as sign up, should never be placed on the client side or embedded with the front end application, but instead be placed on the server side hidden from the user for the sake of safety of your database/application. If you are only considering to put your php with your Android app together for the case you need to test it, and eventually doesn't have access to a server, you may then consider using Google App Engine, as it allows you to emulate a server locally without the need of a server. Here you find some info about Amazon's RDS.
You can put you php in the same directory you place your index.html file, i.e. in the root public directory of your domain. To load it to the Amazon, you can use the cPanel or the Filezilla or any other panel you wish among the options Amazon put available for their users.
In the case Amazon doesn't provide a place to put your php, as a suggestion, you can get a host that allows you to have a static ip accessing it thorough an easy to remember url address - for free. It is quite useful specially for making tests. Still if you decide at some point to have a personalized domain name registered, there are also some other good options to compare.
You dont need jQuery, when doing the POST request,PHP connects to the database get the data and return it to your app.
So to answer your question you should put the PHP in the same server where mysql runs.

I have a static website developed through 11ty (Node based SSG), which contains a Contact form that sends a request to a nodemailer API with the data. Both are hosted on Render, as a Static Website and Web Service respectively, and they share a basic auth password which I've stored in each project as an environmental variable.
The Web Service accesses the variables just fine. However, the static website's event presents me with the error in the title "process" isn't defined, as in "process.env.VARIABLE_NAME" which is how I'm accessing them. I tried including a secret .env file in the project with the same key and including dotenv in the project, but no change.
I assume the nature of the static site is making it so the environmental variable isn't being processed/applied somehow. What possible steps could I be missing here?
EDIT: Although it seems it might be possible for me to do this through methods such as command line arguments (which then get injected into the code during the build process), that wouldn't work for my case since the password had to be secret in the generated source files. The dotenv package didn't work in my case. Finally, I've opted to discard this password-based authentication instead and simply use honeypot fields to prevent spam and CORS Origin headers in the API to control request source.
Your static site is running in a different context than your web service (which acts like a server). Since your static site is run from a users browser, it does not understand node-specific functionality like loading files or accessing your process environment.
Adding your password to your static site would also create a security risk, because a user could just see your password, take it, and run their own requests without any security your site may have.
A usual approach to this would be to create an API of your own that takes in a request from your static site and talks to the API directly or a technology stack that takes the page rendering to a server (like ServerSideRendering). This way, YOUR system takes care of calling the API while your users requests are restricted.
I want to upload file into folder from which my Angular app is served while running on localhost. I'm not able to find any solution without using backend.
For example I just want to upload an image file and that file should copy in specified folder of the project. This should be done only with Angular without using any Backend script or hitting any API endpoint.
Depending on your webhost, you can make your assets-folder accessible via FTP.
Making a FTP-call from javascript (angular is javascript) isn't that difficult. And there are plenty of example and questions about it on the internet (like this)
Why you wouldn't do that:
The credentials for your ftp-connection will be accessible in the compiled javascript-code. With a little bit of effort, everyone can find it.
Each gate you open through the webhosts firewall, is a extra vulnerability. Thats why everybody will recommend you to add an API endpoint for uploading files so that you keep holding the strings of what may be uploaded.
Edit:
As I read your question again and all the sub-answers, I (think) figured out that you are building an native-like app with no back-end, just an angular-single page front-end application. An I can understand why (you can run this on every platform in an application that supports javascript), but the problem you are encountering is only the first of a whole series.
If this is the case, I wouldn't call it uploadingas you would store it locally.
But the good news is that you have localstoragefor your use to store temporary data on the HDD of the client. It isn't a very large space but it is something...
The assets folder is one of the statically served folders of the Angular app. It is located on the server so you can't add files to it without hitting the server (HTTP server, API, or whatever else...).
Even when running your app on localhost, there's a web server under the hood, so it behaves exactly the same than a deployed application, and you can't add files to the assets folder via the Angular app.
I don't know what exactly you want to do with your uploaded files, but:
If you want to use them on client side only, and in one user session, then you can just store the file in a javascript variable and do what you want with it
If you want to share them across users, or across user sessions, then you need to store them on the server, and you can't bypass an API or some HTTP server configuration
Based on your clarification in one of your comments:
I'm trying to develop a small speed test application in which user can upload any file from his system to check upload and download speed.
The only way to avoid having you own backend is to use 3rd party API.
There are some dedicated speed test websites, which also provide API access. E.g.:
https://myspeed.today
http://www.speedtest.net
https://speedof.me/api.html
Some more: https://duckduckgo.com/?q=free+speedtest+api
Note, that many of these APIs are paid services.
Also, I've been able to find this library https://github.com/ddsol/speedtest.net, which might indicate that speedtest.net has some kind of free API tier. But this is up to you to investigate.
This question might also be of help, as it shows using speedtest.net in React Native: Using speedtest.net api with React Native
You can use a third party library such ng-speed-test. For instance here is an Angular library which has an image hosted on a third party server (ie GitHub) to test internet speed.
I'm stumped. So I've written a nice little web app that gets all its data from a JSON that has one array in it. To bridge the AngularJS-parts and the data, I have this line in my services.js
.constant("baseURL","http://localhost:3000/")
This of course only works with me locally. But I haven't considered that I might have to get my web host to serve up the data.
Now, I'm a complete beginner at this. I've managed to code my app with moderate effort, having only started coding in January. So I'm completely out of my league here. I don't even know what I'm looking for. I mean, I have to replace the localhost:3000with something. But if I do http://domain.com/db.json that obviously doesn't work.
I've talked to Godaddy's tech support and they go "Nuh-uh, not helping" the second I show them this line of code. Because, to be honest, I don't even know what the address I'm looking for is called. Is it a URI?
I have a few questions regarding this and I turn to you, because - this story gets worse - there's a possible job on the line for me. Not a coding thing, but the data that is parsed from the JSON into the site.
What is the address I'm looking for called?
How do I get my hosting to serve up JSON data? I mean, I don't even know what I need to ask the tech support people here. Do I need a JSON server?
If they don't offer it, where could I get my JSON data served in a way that I can push more articles into the array and preferrably edit it, too?
Thank you so much!
EDIT #1
If it helps, here's the contents of my /webroot/personalfolder
You will need to change your localhost:8000 to your domain name. For example, if you bought www.foobar.com then your base URL would just become www.foobar.com On a rented web server (like GoDaddy Hosting) ports 80 and 443 are normally open so you wouldn't need to specify this. If you are self hosting, you will need to open these ports on your router and apply port forwarding rules to your PC.
When you host your published website, you will just put your JSON file in with your Website Source. For example your structure may look like this:
AngularAppFolder/index.html
js
csss
Just add another folder called db place your JSON file in there, and reference it in your Angular code, no need to worry, its just another file just like your HTML or CSS which makes up your website. Remember though that your JSON data will be publicly available here!
If your looking for an alternative way of getting your JSON data, you may want to look into creating a REST API. This uses a web server to dish out data depenant on the HTTP request you send to it. but that's a very big topic! Here is some reading into it if your feeling brave! Node.js REST API tutorial
Final note: if you are self-hosting this application (running it on your own computer or server) then you will need to change the DNS record for your domain name to the global IP address of the server! you shouldn't have to worry if your using the hosting offerings from a company such as GoDaddy however.
You need to change the baseURL value to whatever the URL on which the site is hosted. Something like http://<mysite>.com.
I'am searching for days now but could not get an answer.
I would like to do the following:
User connects to editor.html (Apache2 with basic http auth)
User want to open a file (lets say /home/user1/myfile.txt) on the server with his user/pass (same as in passwd)
Node.js Script gets startet with user rights from above and user can edit file
The Node Script will handle the connection via websockets and read/writes files.
I think the biggest problem is that its not possible to run a node script on the server from a web page... and I don´t want to involve any php/cgi scripts... only Apache and Node.js / JS.
Please also comment or answer if you know that it is really not possible...
Thanks!
Kodak
Edit: The workflow should be the following:
User access webpage -> enters his credential (same as in passwd) -> node.js script gets started with the user rights of the logged in user -> files getting read or written with user rights
Biggest Problem: who starts the Node.js script? Apache? How?
I hate to be this person, but...
That is not the way node is designed, it is designed to use the event loop, I would recommend having node serve the static files, maybe using apache as a proxy, then when someone requests a certain page, doing what ever needs to be done, if you really must spawn a child process, use child_process.spawn, as for the rights of the user, I recommend just passing in a code, like 1=admin, 2=user, 3=guest, and the child process can do what is needs.
Use Socket.io - Official Socket.IO Website
You can also use Express with socket IO to create a separate app server. - Express JS Website
You may want to consider security implications of allowing a user to connect directly using their server side account. There are also many applications available that already do this that you might consider implementing instead of writing your own, with all the properly embedded security that will be required.
Let your users GET static auth.html page (via apache) without any authentication.
Let form submit action is some auth.js (Node.js script). This auth.js check if user's authentication is success. If so it starts node.js server, setups socket.io on it and redirects user to some editor.html.
In this case as you can notice that there is an authentication based on node.js scripting. If you want basic apache2 one I can recommend you the next scenario:
There is auth.html and editor.html pages on the server. Last one placed in /private folder and direct access to this folder is denied by .htaccess. So when the user pass apache2 authentication in auth.html he GET this auth.html which is empty document with onload event handler that send AJAX to auth.js (Node.js script). Node.js get private/editor.html and send it to user like /editor.html.
In this case user never has an access to editor without passing authentication. And after authentication node.js server is started and socket.io is setup and everything fine.
I found a solution:
It is possible to write a custom authentication program for apache with mod-auth-external:
https://code.google.com/p/mod-auth-external/
With basic authentication enabled the webserver would pass the credentials to a script/program and this can then run the node app.
I'm currently redeveloping/designing a department website at my university, but an internal organization who handles the servers/current CMS system are being ridiculously uncooperative. I can't get access to the templates of the current CMS and I can't develop my own templates for the system, so I'm trying to move away from it (EZ Publish). But I also can't get admin access to a server, so I'm unable to install PHP/MySQL to get Wordpress up and running.
Basically, all I have access to right now is a public/ folder. I'm considering writing a pure frontend app with backbone or something, but my boss wants the option of the dept heads to edit information. I want to avoid rolling together my own custom CMS if possible, so I was wondering if anyone knows of a pure front-end CMS manager that doesn't require a server language and server database.
that's a hard one, first because you have to have a way to maintain the data and that's not possible in front end, if the server is working RESTfully, that may be possible, but in other cases, I don't think this is a choice, because no cms will be able to communicate with an existing server cms.
Host a wordpress somewhere else and install the JSON API plugin. Enable CORS on the remote server. Build Your frontend with static files that interact with the service. Host them in the buggers public/ directory.
The admin/post editing tasks will have to be done on the backend host, but hopefuly you'll be able to get a subdomain from your university to point there.
another approach to this problem is static website generators.
you can host the content and data for those in a university internal or other code repository and push the generated content to the site.
to allow your depearment heads to edit information, find a site generator that allows you to seperate structure and layout from content, so that they can edit simple text files to add content, hosted on a shared storage they can all access.
