Deploy django and angularjs - angularjs

structure of my application looks like:
myapp
--backend
--env
--frontend
-- .idea
-- app
-- assets
-- bower_components
-- views
-- .htaccess
-- index.html
-- node_modules
flag
I used Django as an API and returned the JSON objects from the API and use the data in my AngularJS app in front-end.Both frontend and backend are running on different ports. In the development server, I used start the django server using the following command:
cd backend
./manage.py runserver 127.0.0.1:8000
and start the webserver using:
cd frontend
grunt serve
Now I want to move my application on production server.. So please suggest me how to do it. I have setup the production server (django with apache2 and mod_wsgi). But I dont know how to integrate angularjs with that..

I am currently running few projects in which i use django at the backend and angularjs at the front end.This is what i did.
1.All my javascript files are served from static folder.
2.Returns an html from django on initial load.
3.The html file loads scripts required including angular.js mymodule.js and mycontroller.js from static folder.
4.data required for the page is loaded by sending ajax requests inside controller.js to django server for which django returns json response.
5.The response is renderd in page using angularjs

How to deploy a react application on a static server

I have a react application build with create-react-app. Its using octoberCMS as the backend fetching data using Axios calls from the frontend. Till now I was developing keeping the build content of react inside a directory named 'react' in the root directory of octoberCMS installation. Hence the URL I was hitting was http://example.com/react/.
The problem is now I am done with the development phase and look forward to deployment. But I want my front-end to be served at http://example.com and backend to be served at http://example.com/backend (backend served as I want). How can I achieve this? I am fairly new to both frameworks.
I have tried keeping the build content along with the rest of the octoberCMS
First build your react app that will give you vendor.js[third party scripts] and your app.js[your actual app]
put them in to theme directory assets something
Then In Ocotber CMS make page with URL /:url? and paste your index.html content there.
it will be your root div and including js html, change path for js which points to the build js which you put in theme directory.
now what happens when anybody come to site
- we are serving same content as we do in dev build
- index.html with root tag and needed js
Now if use hit any other url like https://www.example.com/test/etc it also will be catch by /:url? (and all other requests) and home page served and our react app will work as we needed.
if any questions please comment.

Serverless Offline <> React - Local Dev Page Load

I have a serverless application that is using the serverless-offline plugin and create-react-app to load a front-end client, but I'm not sure how I can configure my serverless app to load the index.html page and also the proper link format that I can use within my react app to call the serverless-offline generated routes.
I know that serverless applications typically use a static website hosted on S3 and AWS serverless endpoints within the static links to trigger the handlers, but I'm not sure how I can replicate this in the local environment. Can anyone point me in the right direction?
This is my code structure at the moment:
- frontend (create-react-app)
-- create-react-files
- backend
-- controllers
--- login.js
I then have a proxy set up in my create-react-app config file set to serverless-offline port I configured in my serverless.yml file

Build React app with express backend for domain http://example.com

I have a web application in React that I needed to implement a contact form. The application is created using create-react-app and the server folder added. For the form I used sendgrid mail. Does the server work on port 4567, how do the app build to work on the domain? It is a one-page application.
Thx, it is important.
When running in production, a React app is simple HTML, CSS, and JavaScript. These files are sent from your server to a client when requested in the same way that requests/responses are handled for any web page. There are a few steps that need to be done before your React app is ready for production
1: Create a Production Build
First you need to create a production build of your app. This process takes all of your separate .js or .jsx files and puts them together into a single minified file, and the same for .css. Then your index.html is updated to include a link to the CSS and script to the JS. This is done so that only three files will need to be sent rather than the 10s or 100s that exist in development.
If you used create-react-app to start your application, you can use the command:
npm run build
to do this. Otherwise, you need to have webpack installed, and then run:
node_modules/.bin/webpack --config webpack.prod.js --mode production
(which you might want to add as a script to package.json).
See React: Optimizing Performance for more.
2. Serve your Application
Now your server should have a route for your application and when it receives a request on that route, the server should respond by sending index.html from your client/build/ directory (where client/ is the directory of the React app).
Here is an example with Node/Express as the server (in app.js):
const path = require('path');
app.get('*', (req, res) => {
res.sendFile(path.join(__dirname), 'client', 'build', 'index.html');
});
Note that this is just the way to send a static file using Node and can easily be done with any server.
Additional
You mentioned you want to submit forms with your application. If your routes for receiving POST requests match the routes that the forms are on (e.g. form is on /form and server listens for POST on /form) you can just use the default HTML form submission. However this is not a great way to do things when using React because then routing will be controlled by your server rather than by React. Instead you should use some sort of AJAX method to submit the form.
Since your server is now serving your React app (rather than React serving itself as in development), you can just make relative requests and those requests will be made to your server. For example the request (using the fetch API):
const models = await fetch('/api/models');
Will be made to your_host/api/models by default.
in the package.json add
"proxy": "http://localhost:4567"

react + webpack - pass POST data to build

Coming from a PHP background, I used to have an index.php which does two things:
serve the webpage if no parameters were set;
or serve JSON data when a specific POST parameter was included in the request.
Something like this:
// -- index.php
<?php
if ($_POST["some_parameter"]) {
...
echo json_encode(someArrayData);
exit(0);
}
?>
<html>
...
</html>
I have built the complete frontend application with npm, webpack, webpack-dev-server, and react. Having completed the first part, how can I effectively serve JSON data instead of HTML when a request includes a specific POST parameter?
I can see 2 ways of doing this:
Build the frontend as usual and everytime I build the bundle, modify index.html, inject my PHP code in it, and rename it to index.php. I then would have to run this folder via apache or nginx, so I'd be able to run the index.php script. This method is downright ugly and is probably the worst way to do it.
Run a separate PHP server which just serves data or redirects to the static webpack-generated build. All requests should then start from this server, and this server determines whether to serve data or redirect to the frontend. The problem comes to neatly passing the POST data received from the request to the static react app. As far as I know, the only way to do this would be to include a URL (GET) parameter to the redirect and manually parse it with javascript on the frontend. This is a dirty solution, in my opinion.
So, to summarize:
I need an efficient way to get POST data in a react/webpack/webpack-dev-server environment.
It should work with my hot-module-replacement dev setup.
I'm fine with switching to a node-based backend like express.
There shouldn't be any ajax involved in the static react app.
Any ideas? There has to be a way to do this properly.
UPDATE: I solved this by simply copying an index.php from my source directory to my build directory via the webpack config. I serve the build folder to a PHP server and keep a webpack --watch building my source.
I lose built-in features like auto-reload and css injection, but it's worth the convenience of not having to implement SSR for a very simple task (getting a single POST variable).
For anyone interested, I also added 2 npm scripts:
npm run start runs my original webpack-dev-server with hot-reload, serving static content including a static index.html file
npm run static runs the webpack --watch which copies the index.php file to the build directory
This lets me have hot-reloading when developing frontend, and allows POST data fetching when programming logic.
It's easy, convenient, and works on most web hosting providers.

Apache 2.4 - Never expire to all files, except 'index.html'

I'm using gulp-rev-all for my Angular based WebApp and I don't want to revision index.html. All other files are revisioned by gulp-rev-all, so they will change their names after each deploy.
How to tell Apache to not cache index.html (always fetch index.html from the server), but all other files in my WebApp must never be expired until I deploy new revision?
Take a look over here, it's some config that will turn off caching based on a pattern:
