So I'm using cPanel with Setup Node.js App plugin for a Next.js app. (don't asky why cPanel)
Everything is working as expected in development, except for environment variables in production, I set up them manually from the cPanel interface, I restarted/stopped the app, logging the process.env on the server and I don't see the env variables there (not to say when trying to call them they are undefined).
When doing
res.json(JSON.stringify(process.env)); i get a bunch of variables except for the one I manually wrote in cPanel variables interface.
It is important for me to store these variables as secret key because they are API credentials.
Anyone know what I might have misconfigured or had this problem?
Never mind, found the answer, apparenlty was a Next.js misconfiguration. I had to add the following lines of code inside next.config.js in order to read env variables on build version.
require('dotenv').config();
module.exports = {
env: {
EMAIL_NAME: process.env.EMAIL_NAME,
EMAIL_PASSWORD: process.env.EMAIL_PASSWORD,
GETRESPONSE_API_KEY: process.env.GETRESPONSE_API_KEY
}
};
Where EMAIL_NAME, EMAIL_PASSWORD, GETRESPONSE_API_KEY were the variables defined by me on cPanel interface

I am trying to complete a Redux project and got everything to work fine in development on my own machine but when deployed, the browser is failing to recognise my hidden environment variables so not passing client keys to Api calls and thus making unauthorised requests. I have a '.env' file with the keys in them and then refer thus...
const API_URL = https://api.openweathermap.org/data/2.5/weather?appid=${process.env.REACT_APP_OPEN_WEATHER_MAP_API_KEY}&units=metric;
I have looked up the problem on here and think I understand what's going wrong but don't know how to put it right. I am deploying site via Netlify from my Github repo and my build settings appear to be correct. I thought 'npm run build' took care of all that for me?
99% finished a project and now scratching my head furiously...
Try defining variables in .env file starting with REACT_APP like:
REACT_APP_CLIENT_ID=4
REACT_APP_API_URL=/api
Try using it anywhere like:
const apiUrl: process.env.REACT_APP_API_URL;
Set the environment variables specifically within the Netlify UI. So 'Deploy Settings > Environment > Environment Variables' then variable -'REACT_APP....' value - '*****' for each variable you want defined.
hi im trying to make forgot password/reset password service.
let me show you the logic of this service.
(simply, send email in react(localhost:3000/forgotPassword) -> click link in email -> route to localhost:3000/resetPassword)
1.send email in frontend
The content is to write down the email of the account you joined.
2.email
비밀번호 리셋하기 <- this is direct to http://localhost:3000/resetPassword
3.forgotPassword.js in node.js
Here, I want to change resetURL(http://localhost:3000/resetPassword) to dynamic URL. Because I will distribute this soon.
3.package.json in react
I was able to do api communication from react to node by specifying proxy here, but /api/resetPassword does not work in node.
To sum up, I want to use the code used by React on the node as well. Like this.
You are looking to environmentalise your configuration.
You could do it through an environment variable, like this:
const baseURL = process.env.BASE_URL || 'http://localhost:3000'
const resetURL =`${baseURL}/resetPassword`
If you use the dotenv package, you can support configuration through environment variables or from a .env file.
If I understand correctly, your interested in setting up a dynamic variable for the url in your react app. Try just setting an environment config file, either a file for each environment you are developing in (i.e., Dev, QA, PROD) or a single file with multiple shared Env variables. You can even add an env variable to your package.json file for example.
NOTE the approach below would work for linux and mac, but not windows
please use the resources below for more information. This approach has been made available for react-scripts#0.9.0 and higher.
{
"scripts": "APP_URL=http://localhost:300 npm start"
}

I'm fairly new to node and express...
I have a constant I set in my Node/Express application for "Domain". I'm constantly switching between localhost and the actual url when I switch between development and production.
I'm trying to figure out how I can automatically test the URL so that when the code is read on the server (ie actual domain url vs localhost) that it sets the proper domain url.
Here is my code:
function define(name, value) {
Object.defineProperty(exports, name, {
value: value,
enumerable: true
});
}
define("DOMAIN", "http://www.actual_domain.com");
// define("DOMAIN", "http://localhost:3000");
Anyone have a simple solution for this?
Thanks!!
there is many solutions for this, but usually this is done by environment variables, depends on your platform, but, in Linux systems, you do the following in your shell
export ENV_URL="http://www.example.com"
and to make sure its exported successfully
echo $ENV_URL
and in your code you do
const base_url = process.env.ENV_URL || "http://www.default.com";
in your local machine you set the ENV_URL to localhost or whatever you prefer, and in your server you set it to your actual URL.
or you could simply have many configuration files and you can determine the appropriate one by the environemnt variable like
export ENV=PROD
and in your code you can load the prod configuration file that contains your environment configurations.
The de facto way to do this sort of thing is through environment variables. Have a look at 12factor.net for a load of best practices, but in general you want to put differences in the environment into environment variables, then read those variables at runtime.
Okay, I'm new to node, and really only just using the node server to serve static js, but I can't find any info on this anywhere.
I'm running an application ember app kit, which gets built to a node server.js for deploy, and heroku runs it with node server.js.
It uses grunt for building, testing, etc.
I'd like to know how I can specify configuration variables (i.e. authentication tokens) that can be overridden by heroku config variables.
The closest I've been able to get is a custom task that reads environment variables and writes out a json file that gets built into the site (and assigned to a global var). This works locally, but doesn't take into account heroku configs.
I even wrote a deploy script that gets heroku's configs, exports them as environment variables locally, and does the build--Which works, but the configs only get updated on app deploy. So if I do a heroku config:add CONFIG_TEST=test_value, my app doesn't see that value for CONFIG_TEST until the next time I deploy the app.
I'd like for my app to start embedding that config value in the browser JS immediately.
Any way to do this with node the way my app is set up?
I am not sure I understand what's wrong with simply taking config variables, at run time, from the environment. Use process.env.KEY in your code, and embed that result into whatever template you may have, and serve that as the result.
When you change Heroku config variables your process gets restarted, so it picks up the new values.
Is the problem the fact that you serve static files? If so -- can you simply change it so that you use a template engine to do some processing on them before serving?
OK, here's a solution for ember-app-kit using grunt-sed.
In EMBER_APP_KIT_PROJECT/tasks/options/sed.js
Add something like
module.exports = {
version: {
path: "./dist/",
pattern: '{{env.API_BASE_PATH}}',
replacement: function(){
return process.env.API_BASE_PATH;
},
recursive: true
}
};
then in your code just put
"{{env.API_BASE_PATH}}"
Now, when you run
$ grunt sed
it will replace "{{env.API_BASE_PATH}}" with whatever's in the environment variable.
I'm trying to use the node-config module to change some parameters of my configuration (basically logging level) during runtime.
In the official documentation says:
Environment variables can be used to override file configurations. Any environment variable that starts with $CONFIG_ is set into the CONFIG object.
I've checked that this is true when the server starts but it does not seem to work once it's up. (The handler of the watch function is never called when an environment variable is changed unlike a change in the runtime.json file or directly changing a config variable).
I'm currently watching the whole CONFIG object like this:
var CONFIG = require('config');
CONFIG.watch( CONFIG , null , function(object, propertyName, priorValue, newValue){
console.log("Configuration change detected");
});
Does anyone know if this is possible?
The environment is available during startup of a process.
If the process is running, you won't be able to change the environment anymore, the process is in.
The only option is to restart the process or use other mechanisms to communicate with it.
Say for example having a rest or tcp listener inside, where you can transfer your variable inside.
Best regards

As you must knowing, React is a single page application which is eventually when it is complied is a static page app that means all the files of the react application is complied into vanilla JS and CSS file bundle in a Tarball. Now that Tarball is eventually deployed on a web server. It could be Apache web server, nginx web server or anything which you are using it but an important point is the static app is running in someone else browser and someone access to website CSS and JS are downloaded in a browser and it is running in the browser runtime environment so technically you cannot have a runtime environment variable for someone else browser but may be there would be a way to access them during runtime.
SOLUTION
I have achieved this goal with the package called runtime-cra.
follow the steps on this official documentation: https://blog.risingstack.com/create-react-app-runtime-env-cra/
