Have nodeJS refresh angularjs2 files without re-compiling with npm start - node.js

I am using angularjs2 with typescript in the client side and nodejs and express in the back-end, and every time i make changes to my client side files(.ts & .html) while running my node server on port 3000 i don't get the saved changes,so i have to run npm start for the ng-2 lite-server so that it like refreshes to get the changes, I am not sure whether i need a single module loader like SystemJS, which is the one i am using with ng2, or i need another systemjs required in my server so to get changes after saving.
In my server file i have
app.use(express.static(path.join(__dirname, 'client')));
that loads the static files, and which loads the index.html file that has the lines which i learn that they load application modules for ng2
<script src="systemjs.config.js"></script>
<script>
System.import('app').catch(function(err){ console.error(err); });
</script>
Since my server loads the index.html which contains the above code, im expecting nodejs and express to load the updated files accordingly, or is it because nodejs uses commonJS instead of system?
Is this the right way to do it or there is a better integration method for ng2 and nodejs?
What are the efficient options that are there in this aspect?

I'd suggest using pm2 to run your node server. The --watch flag will restart node (non-gracefully but quickly). If your Angular app is inside the node app folder then node will restart given just the flag, if it's outside that then you can pass a specified path to the --watch flag.
pm2 is a Production quality tool for Node, and works great locally too.
Details: http://pm2.keymetrics.io/docs/usage/watch-and-restart/
Example cmd: pm2 start index.js --watch

Deploy angular 7, mongo, express, node application on own server

I would like to deploy my angular application with nodejs, mongo, express js on my own server.
My way is:
-> ng build --prod (output is dist folder)
-> ng serve on dist folder
Start backend:
-> node server js file
But I think, it is not correct way od production stage. Added http server on express, there I create another index html view file with hbs, and there I use:
<body>
<my-app>Loading ...</my-app>
<script src="/dist/bundle.js"></script>
</body>
But on dist server, there is multiple js files.
How can I create using ng option (no webpack or must be f.e. webpack?) my angular/mongo/node/express application (in 1, my own server, no aws, heroku, github etc). There is any correct way to do it?
I've been able to deploy an angular app using Caddy Server as the webserver.
Create a build of your Angular code by doing ng build --prod-true.
This creates a set of bundled Js and Html files in the dist
directory.
Copy these files to where you want to run the app.
Next go to the Caddy website and download the version of Caddy for
your os. You can choose all kinds of features but for my deployment
inside a firewall a plain build worked fine.
Drop the caddy file in the directory that you put your compiled
angular code.
Create a caddyfile (just a file named caddyfile), add localhost:(your
favorite port number).
Run caddy and it will automatically serve your app by launching
index.html. You can view your app at localhost:port.
No messy node installation. Caddy has all sorts of add-ons to deal with more complicated scenarios but the deployment is caddy.exe, caddyfile and your built code.

How to run a node app after production build by WebPack when output is index.html?

***Updated for further clarification:
Thanks much for taking the time to reply. Running 'npm run build' (I'm using the Vuetify/Webpack template) created an index.html and a directory named 'static' with the respective html, css, and js (in 'dist' directory). The question is - how can I run this in production using node or pm2 (for example, 'pm2 start myapp.js')?
Doing some further research and testing, the 'npm run build' built as static. It was my lack of understanding how vue-cli was to build for production (via WebPack) (vue-cli builds static meant to be served via web server). Doing further testing, I can load and bring up my app on a couple local Linux servers (the static content running on one servers, while MongoDB and API running on another server (API running with pm2)). Also, I was able to bring it up on AWS S3 (as static). I think I have my answer now. Thanks much for your time.
***From Original Post:
How to run the following node app in production? Webpack build produced an index.html (I assume as it's using html-webpack-plugin). I can view the site if I run under a web server (e.g., nginx), but I want to run my final app using pm2, or running node process.
I am using the Vuetify WebPack template (I'm using Vue.js), when I run the npm run build for production (in package.json: “build”: “node build/build.js”) the output is as follows:
$ ls
index.html static/
and
$ ls static/js/
app.f7301c212bc5fefd6563.js manifest.2ae2e69a05c33dfc65f8.js vendor.1aae36aa0dc798d4d36d.js
app.f7301c212bc5fefd6563.js.map manifest.2ae2e69a05c33dfc65f8.js.map vendor.1aae36aa0dc798d4d36d.js.map
So, how do I run this via node (npm start) or pm2 (pm2 start) (can't use index.html or static/js files).
When I run the webpack build I was expecting a .js output (for example ‘build.js’) to run via node or pm2 (npm start that runs ‘node build.js’ or pm2 start build.js). I suppose this will work for serverless, but was looking to run via pm2 (with nginx as proxy) as the app will have other factors (e.g., MongoDB) that won’t allow running in serverless (e.g., AWS Lambda).
Would this be a matter of just re-configuring WebPack to output to a .js file (for example, build.js), or will the static files (served via a webserver, nginx/Apache/http-server) allow for the same functionality? That is, will there be any factors that would limit my app by running as static verses via ‘node build.js’ or ‘pm2 start build.js’, (for example, will my API connects to the back-end still work (back-end being node/JS))?

Serving Node Server and Angular 4 application in one command

I am starting a new project which is using Angular 4 for frontend designing and the application will need some rest api's for which I have decided to use node. I am using angular cli for creating angular app and I know how to create angular app and node server but I want to know how will I connect these two things such that when I do ng serve both the server and angular app gets compiled and run. What basic changes in the project structure or some file is needed to be done?
I'm currently building a full-stack Angular app with a Node/Express backend and was wondering the exact same thing. However, despite what that scotch.io tutorial tells you, creating both the Express server and the Angular app in the same directory is NOT the best way to go about it.
What you want to do is set up your Express server in one project and serve it in one terminal window, then serve your Angular app in a separate terminal window but have it point to your locally-running Express server instead of the default dev server that's included with the Angular CLI (the ng-serve command).
Here's a Stack Overflow answer and also a Medium article that answered all of my questions for how to set this up (fortunately, it's not too hard).
Here's what I did Shubham. I went into the Angular-Cli and changed "outDir": to "../public"in other words it will look like "outDir": "../public". The ../public folder is my Express static folder set in my app.js file with app.use(express.static(path.join(__dirname, 'public')));
Keeping in mind I have nodemon installed globally, and in my package.json file, "start": "node app" I simply run nodemon from this dir to start my server and both Angular and Express run on the same server.
I have seen some people say it's not good to run static filed on the Node/Express server, but for development I'm not sure it matters. Although I'm a novice when it comes to js frameworks etc. Here's the project files on my github acct: https://github.com/chriskavanagh/angularauth.
Edit: You must run ng-build (in your Angular dir) whenever you change code.
First, in Angular project do ng build, it will create dist folder (static folder).
Second step, paste the following code in backend servers entry point file.
app.use(express.static(path.join(__dirname, 'dist/')));
app.get('*', (req, res) =>{
res.sendFile(path.join(__dirname, 'dist/index.html'));
});
And after the above thing is done run backend server: node filename
Note: in give proper path where your index.html file is located in dist folder.
The node server and the Angular app are two different things.
In order to run the node server you should use the command:
node ServerName.js
In order to run the angular app you should use the command:
npm start OR ng serve
In your case, the connection between the two is made by http requests.
For example you could use 'express' in order to implement rest services in your node server and then send an http request to the server in the current route.

vue files without NodeJS?

I want to host my app outside of node JS, but I want to use .vue files and possible npm as build system (if it's needed). Is it's possible to do?
I do not need any backward compatibility and if it work on latest Chrome dev it's ok for me.
Is there any examples how it can be done?
I tried to build some webpack template, but it's work only inside NodeJS. On other server I am getting 404 when I am accessing to URLs that placed in .vue files. It's seems that they can't be handled by the other server.
VueJS app is not NodeJS app.
VueJS app is interpreted by the browser.
You just have to build your app on computer and host files as any static website, so any server can serve html and files.
To build your app use e.g. Webpack (https://github.com/vuejs-templates/webpack )
NodeJs only use to build *.js files in front-end, your WebApp dosen't have to run on Nodejs.
1, You can create a index.html file that requires *.js file when webpack built it.
2, Use Chrome to open your index.html file so you can see it works.
You don't need to use vue-cli or other servers if you only want a static page.
But you have to know how to set your webpack.config.js, you can look that doc https://webpack.js.org/guides/getting-started/
Your starting point is wrong. Vue + node.js can build a complete site. Vue is the front-end framework, node's server language. The two can be used in combination. But not vue must rely on node to use. The two of them can be perfect to achieve the front and back separation of the development model.
In projects that use vue, individuals do not recommend configuring webpack and vue-loader separately. You can directly use vue official scaffolding, vue-cli. Do not have to consider these configurations, automatically configured.
Vue-cli
If you just started learning Vue, here's an entry-level demo. Although it is only a small application, but it covers a lot of knowledge points (vue2.0 + vue-cli + vue-router + vuex + axios + mysql + express + pm2 + webpack), including front-end, back-end, database and other sites Some of the necessary elements, for me, learning great significance, would like to encourage each other!
Vue Demo
Best way to develop Vue app is run dev server, and after all just build static assets. You don't need use vuex files, even better is use static template because you can easily integrate it with some back-end (WordPress or whatever).
Helpfully will be use some starter, for ex. Vue.js starter
It's true that vue will create static html pages when you run the build script. However, you will need to serve the files from a small server for the site to work. If you notice, when you run npm run build, the terminal will print a notice...
Tip:
Built files are meant to be served over an HTTP server.
Opening index.html over file:// won't work.
You can create a simple http server in your /dist directory with express and then host your site somewhere like Heroku.
Take a look at this article https://medium.com/#sagarjauhari/quick-n-clean-way-to-deploy-vue-webpack-apps-on-heroku-b522d3904bc8#.4nbg2ssy0
TLDR;
write a super simple express server
var express = require('express');
var path = require('path');
var serveStatic = require('serve-static');
app = express();
app.use(serveStatic(__dirname));
var port = process.env.PORT || 5000;
app.listen(port);
console.log('server started '+ port);
add a postinstall script in a package.json within /dist
{
"name": "myApp",
"version": "1.0.0",
"description": "awesome stuff",
"author": "me oh my",
"private": true,
"scripts": {
"postinstall": "npm install express"
}
}
push only your /dist folder to heroku after you've compiled your site.
proof: I've followed these steps to host my vue.js project
using vue files without NodeJS (nor webpack) is possible with vue3-sfc-loader.
vue3-sfc-loader
Vue3/Vue2 Single File Component loader. Load .vue files dynamically at runtime from your html/js. No node.js
environment, no (webpack) build step needed.
vue3-sfc-loader will parse your .vue file at runtime and create a ready-to-use Vue component.
disclamer: author here
Could you try something as simple as an S3 bucket setup for web serving? How big is your project? How much traffic do you think you'll get? If it's very small, you may be able to host on S3 and use webpack, etc.

How do I use Webpack with ReactJS and NodeJS?

How do I use Webpack with ReactJS and NodeJS? My problem is both the server and client have source that needs to be transpiled through (babble et. al.) but the Webpack config file only has one output file.
What I need is my node app build and my client side app built and put in build/.
Webpack won't compile your server code. You'll need to configure babel to transpile your server code when the server starts. Why do you need both server and client code in a /build/ directory? It's better to keep them separate.
