I am creating a blogging application using Node, Express and Next.js. I have successfully deployed the frontend portion of the application however I am running into an error when trying to connect to the backend server:
Error: secret should be set
Here is a link to my Github with all the code https://github.com/DragonKnightLeo/Blog-API
This is my first fullstack application so I am pretty junior at how all this works.
I just went through the code and tried to see if I can run your code in my local.
Also, saw the error that is coming when you run the code in your logs above. Seems like you do not have a .env file or JWT_SECRET mentioned in your env file.
Try adding env file and use dotenv node module to bootstrap it along the server run.

I have a small react app with a node.js backend (monorepo). The client is using #ffmpeg/ffmpeg, and all works fine locally, but when deployed to Heroku I'm getting the error ReferenceError: SharedArrayBuffer is not defined. This happens when I run ffmpeg.load(). Note that I am only using ffmpeg on the client in the React app.
What I have done so far:
Ensured that my deployed app is using https
Added these lines in setupProxy.js in app.use (located in the client directory). See this answer for context
response.setHeader('Cross-Origin-Opener-Policy', 'same-origin');
response.setHeader('Cross-Origin-Embedder-Policy', 'require-corp');
Registered for an origin trial with chrome. This actually worked, but I'd prefer a more permanent solution that works across browsers.
Tested debugging crossOriginIsolated, and verifying that it is true locally but false on my deployed site.
It seems like something is wrong with my Cross-Origin config, or maybe it's just not being applied. Any help would be appreciated.
This was a silly mistake on my part. The Cross-Origin-* headers mentioned in the question were correct, they just had to be in index.js on the backend, not the client.
I am starting out on React.js after learning Node.js using Express. But I don't know How to Link my Backend App to front end React files? Can someone provide me a simple solution to the problem
You can begin with this steps, you got a thousands of topics about to make a complete and solid infrastructure:
Initialise your node.js server with port, cors (if you need)
Learn how express work with node.js and create your first route
Initialize your react project with or without npx create-react-app
Create your first frontend component and fetch data from your API

I am new to reactJS. I am working on project which uses following :
Front-end : ReactJS
Backend : NodeJS (Express)
Front-end runs on port 3000
Back-end runs on port 8088.
I am planning to deploy application on amazon AWS.
What i am trying to do is load reactJS front-end when i make request on http://localhost:8088/
I know using axios we can make request on backend server and display fetched data.
What would be standard way of loading ReactJS front from the nodeJS ?
I'm not sure if this is the answer you are looking for, but generally in development you use something called proxy in your package.json in the client (react) folder:
{
// Other stuff
"proxy": "http://localhost:8088"
}
and then when you'd want to deploy you'd run npm build for your react folder and serve that generated folder called build. But as I said, you usually do that only when deploying your application onto server, not the actual development.
Also I'd suggest checking some of these videos, that are focused on deployment, because that is what I think you are asking, right ?
I am trying to connect an app hosted in my localhost:3000 port. The back-end is on the localhost:8080 port (not a remote API but on my own PC. I downloaded a pre-created back-end api and linked the front-end to the back-end with MongoDB using an .env file.
The weird thing is that on MongoDB the connection looks ok, following the tutorial I am using. The backend and the front-end also look alrigh, however, I am unable to login with the form in the screenshot.The error I get when trying to login or create a new user is "xhr.js:178 POST http://localhost:3000/login 404 (Not Found)"
It was a bit hard to put the whole code here, so I am linking you to the front-end repo: https://github.com/manuelalonge/complex-app and the back-end repo: https://github.com/manuelalonge/back-end-api
I can understand the issue is most likely on the back-end but I could not understand where exactly. I tried to get back to the previous lessons in the tutorial but it still doesn't get solved.
Probably it is easier to solve this issue with a screenshare session, so if anybody would contact me I'll be grateful.

Your screenshot points to what's wrong. You're posting to localhost:3000, as you know this is the frontend webpack server.
You'll want to create an axios config file and set a base url to hit the correct endpoint.
const axiosInstance = axios.create({
baseURL: 'localhost:8080'
});
export default axiosInstance;
Also, please add some sort of file structure.
I have a running ember.js frontend app. Also have a node.js backend app which can do basic CRUD operations from MongoDB. Using Postman I can see that my node.js app is returning JSON data properly.
I want my frontend to use the backend to do CRUD operations on MongoDB. I am new to ember.js so I want a guideline where I can understand to use the JSON data from the node.js app and use with ember.js frontend.
My ember.js app already is using a mock server. It has a "dist" folder inside.
My adapter/application.js file in ember.js frontend:
import DS from 'ember-data';
export default DS.RESTAdapter.extend({
namespace: 'api'
});
I want to use my localhost:3000 node server here. Do not know where to add it.
DS.RESTAdapter has a host property that allows you to configure the host used:
// app/adapters/application.js
import RESTAdapter from '#ember-data/adapter/rest';
export default RESTAdapter.extend({
host: 'https://api.example.com'
});
But I would not recommend to point that one to a local development server cause that reduces your flexibility. E.g. a team colleague of yours may want to start the local instance on another port. I would recommend to use the --proxy option of Ember CLI's serve command:
ember serve --proxy http://localhost:3000
This will proxy the requests to your local development server.
You may need to customize the adapter and serializer if your API isn't following the defaults of Ember Data's RESTAdapter and RESTSerializer. Please have a look in the guides for a quick introduction to do so.
