I'm running a MEAN stack webapp on Heroku. I have two folders at root level, "frontend" and "backend". Each folder has their own package.json. I have built the Angular app and put it in the "backend/public" folder. I can serve the Angular app from Express and deploy it to Heroku, no problem.
And here is my doubt: the Angular code in the frontend folder has its own dependencies, but when I build the app, run it on Express, or deploy it to Heroku, is it still using those dependencies from the node_modules folder in the frontend folder? Or are these dependencies somehow injected into the built Angular app's minimized code sent to the backend/public folder, for example?
I'm having trouble finding any info on this specific doubt.
I built the Vue app into a folder named dist.
I have backend APIs which are written in Node Express.
When I deploy it on Vercel, I'm getting 404 errors.
Here is my app structure & Vercel settings.
I'm new to Vercel, any help would be appreciated.

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.
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.

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.
I'm currently trying to deploy a hapi.js app to heroku with this file structure:
.git
client
server
The hapi.js server is inside the server folder along with it's package.json file, node_modules and all that stuff.
Inside the client folder, I have all the front-end related things (small angular app with bower_components and a gulp script to inject everything). The server.js from /server is serving both the bower_components and the angular app related files.
My current problem is that, obviously, Heroku doesn't find a way to deploy my app because of its structure, since it needs to have the server and package.json on the root of the project (which i'm trying to avoid at all costs).
So far I tried to put on my Procfile the following:
web: node server/server.js
but unfortunately it didn't let me push because it didn't match any of its buildpacks.
Have you add .bowerrc file
.bowerrc file contains
{
"directory": "client/bower_components"
}
and add bower.json in root.
