I head to create Nuxt SPA with routing and mb API in future like that:
Backend server (on express or smth else) listen and on request give entire SPA to client.
Now user can use everything on client side (include routing) with no more else requests to backend (mb API requests only)
It means that server should give some .html file with js and css files as SPA and it will work on client side.
I tried to run some commands like nuxt build and nuxt generate
It looks like they return a same result - js files couldn't be found
And index.html file doesn't work properly
After some researching I found a solution
But now I got this:
It can't open the fourth js file in another js file. Path isn't right!
Every time I tried to run it as a static html file and from localhost (and also with using Live Server)
I think I did a lot of crutches and there should be another built-in function or feature that allows us to do what I want
I wrote a lot - if I made a mistake or you didn't get smth - please, ask! I need any help
To test your locally built application, you need to serve all files within the generated /dist folder. You can setup very easily a local web server using Express/Node.js as you already have Node.js installed when running Nuxt. Create a new folder and install express via npm (run npm install express).
Then, copy everything from /dist into /public and create a file server.js:
const express = require('express');
const app = express();
app.use(express.static(__dirname + '/public'));
app.listen(3000);
Run the web server with node server.js and you can access your generated files on http://localhost:3000.

I am (very) new to node.js and I am trying to get a development environment started with React.
const express = require('express')
const mongoose = require('mongoose')
const app = express()
// this displays the index.html file
app.use(express.static(__dirname + '/public'));
// trying to see the app.js
app.get('/', (req, res) => {
res.render('app')
})
app.listen(process.env.PORT || 5000);
Right now I am simply trying to be able to view my app.js when I run nodemon. But right now it is only showing the index.html file in the public folder. and when I run npm start it renders both the index.html and the app.js.
I am 100% doing something wrong and am not in my element here. Any help/advice would be appreciated.

Thank you in advance.
Your code is simply serving a static HTML file located in the public directory everytime the user make a GET request to the root (in your case, localhost:5000). It is not interacting with React yet.
Usually when starting a project with React (frontend) and Node (backend), you would create them as separate projects, in separate repositories.
So you could create a React application using a bootstrap such as create-react-app running on PORT 3000 and in another terminal tab, start your NodeJS application in PORT 5000 like in your example. Then, you can call your backend endpoint from your frontend React application, by referencing http://localhost:5000
By doing this, your backend code don't need to serve static files anymore, it can return data such as JSON and make connections to a database for example.
Since your question is not specific enough, you could be talking about server side render. In server side render apps using Node and React, you have a frontend built with React and a Node server that will return the same React code as a string, using the react-dom/server package to help. This is more complex, but basically you will have the same React code on the client AND on the server. There are performance benefits, because the user can see some content rendered right when he enters the page, without having to wait the React bundle (javascript file) to load. If you want to know more about creating a server side render app with React and Node, there is a nice digital ocean tutorial here
If you want to connect your react js project to the node js
In Development
you simply run their server and start it
In Production
You can use sendFile function coming from express.js to run the frontend

I use express for my API. I have a folder named app and another folder named server. app is the client app, using create-react-app as boilerplate, while server is express.js app for the API.
in the app.js file of the server, I wrote
app.get("*", function (req, res) {
res.sendFile(path.resolve(__dirname, '../app/build/index.html'));
})
But then when I call any API endpoint, I get
You need to enable JavaScript to run this app.
in the response. I'm confused; what's wrong?
In the build directory you have more files that just index.html. You also have build/js/main.buildNumber.js and build/css/main.buildNumber.css.
So when your frontend makes a request to https://yourdomain.com/css/main.buildNumber.js, it incorrectly returns index.html not main.js.
Instead, you should serve the contents of the build folder statically with express.static
app.use('/', express.static(__dirname + '/'));
Or you can look into the "serve" node module to host your app. This will work nicely with react-router. npm i -g serve then cd build then serve . --single -p 5000. This will serve your app on port 5000 (http://localhost:5000).
For me, the issue was that I was mixing styles for functional and class based components. Double check that you don't have any dangling this keywords, or perhaps some missing of the same.
Learning nodejs and started to created my own restful API using restify.
I have created a very simple server.js file which contains basically a hello world type example starting up like:
server.post('/api/messages', servicemanager.verifyFramework(), servicemanager.listen());
server.get(/.*/, restify.serveStatic({
'directory': '.',
'default': 'index.html'
}));
server.listen(process.env.port || 3978, function () {
console.log('%s listening to %s', server.name, server.url);
});
which works fine locally. I cant hit http://localhost:3978 and I can test my API calls just fine calling http://localhost:3978/api/messages.
I have deployed my code into bitbucket and now I want to host these APIs in Azure using App Services.
My project structure is like so:
/topfolder
-/myproject
-/node_modules
-/node_modules...
server.js
package.json
index.html
When I setup the new app service in Azure, I can see that the deployment receives the code from BB, but the service never responds to my requests.
I have setup the home path of the app to live in: /site/wwwroot/topfolder/myproject and I can see the index.html when I navigate to http://myproject.azurewebsites.net so thats good.
I actually get a 404 error:
The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.
There are heaps of examples of how to setup continuous deployment using bitbucket and for the most part, they all seem to work, but my server.js file doesnt seem to be the getting called or starting up.
How can I debug whats going on here?
Is the packages.json file used in this scenario by Azure?
Thanks.
As the root directory path of the application hosted on Azure App Services, is D:\home\site\wwwroot. And about the nodejs application, the Azure fabric will find the entrance script in root directory like server.js. And the requests are handled via web.config in root directory. If there is missing server.js or web,config file, you will occur 404 error.
You can try to modify or your application's structure, like to:
-/node_modules
-/node_modules...
server.js
package.json
index.html
Then, you deploy your application to Azure via GIT or from BB, the Azure deployment task will run command npm install and generate the web.config wile in the root directory.
Any further concern, please feel free to let me know.
This is my folder structure:
- getable_challenge
- node_modules
- stuff
- main.html
- main.js
- backend.js
- README.md
I want to load main.js from within main.html. Previously I had been accessing the page using the URL of file:///Users/adamzerner/code/getable_challenge/main.html, and a simple <script src="main.js"></script> allowed me to load the script.
But then I set up a Node server, at localhost:3000, and now it won't load the script. It's trying to load localhost:3000/main.js, which presumably is the wrong path. I'm not sure how to structure this... what should I do?
Server code (essentially)
var express = require('express');
var app = express();
app.listen(3000);
When you use the "file" protocol like that you aren't even using the web app to serve the script, you are directly accessing it on the local file system. That works fine when you are just running your app on your local machine but it completely breaks when you try to run it as a real app since the browser will have no idea where "file:///..." is, or even have permission to access it.
You need to put the client side scripts into a separate directory, usually named 'public', and then make your application aware of it. If you're using express you would do this:
app.use(express.static(__dirname + '/public'));
You want to put your statically served scripts ("public") into a separate directory so as to control access by your clients. If you just put them into the main directory and made the main directory accessible you could expose all your other files to public view, such as config files that sometimes contain passwords.
It also makes your structure much cleaner.
Try adding this line after var app
app.use(express.static(__dirname));
This should make your resources that are within your servers folder accessible. the var __dirname is the path to where your server is executed.
I am new to node. I have created and successfully tested the node app in Heroku. My folder structure is something like this .
app.js ( the server side socket.iofile).
index.html (publicly available file).
when i access the app through the URL from Heroku.
If i access the app.js file like appname.herokuapp.com/app.js i can access the file. Is any way to prevent accessing this server file ?

Well, probably you are using express.static() due to which it can access any static file from your directory.Anyways, you can create a route for app.js:
var app=express();
app.use(app.router); //this will make sure that node.js will check for a route before checking for app.js file and displaying it.
app.use(express.static(__dirname+'/directoryPath'));
//now set the route for app.js
app.get('/app.js',function(req,res){
//what-ever you want should happen when u go to appname.herokuapp.com/app.js
});
Actually am not using the "express".
My code is something like this

My folder structure is like the following:

----css
--------style.css
----images
--------cup.png
--------tree.png
----app.js
