Environment Variables
Cluster has built-in support for loading environment variables into the browser and Functions. Loading environment variables into Node.js requires a small code snippet.
In development, Cluster will load environment variables from a file named .env.development
. For builds, it will load from .env.production
.
AÂ .env
 file could look like:
CLUSTER=https://dev.example.com/apiAPI_KEY=927349872349798
To load these into Node.js, add the following code snippet to the top of your cluster-config.js
 file:
require("dotenv").config({ path: `.env.${process.env.NODE_ENV}`,})
This loads process.env.CLUSTER_API_URL
and process.env.API_KEY
 for use in cluster-*.js
 files and functions.
For example, when configuring a plugin in cluster-config.js
:
require("dotenv").config({
path: `.env.${process.env.NODE_ENV}`,
})
module.exports = {
plugins: [
{
resolve: `cluster`,
options: {
apiKey: process.env.API_KEY,
},
},
],
}
Accessing Environment Variables in the browser.
By default, environment variables are only available in Node.js code and are not available in the browser as some variables should be kept secret and not exposed to anyone visiting the site.
To expose a variable in the browser, you must preface its name with CLUSTER_
. So CLUSTER_API_URL
 will be available in browser code but API_KEY
 will not.
Variables are set when JavaScript is compiled so when the development server is started or you build your site.
import React, { useState, useEffect } from "react"
function App() {
const [data, setData] = useState()
useEffect(async () => {
const result = await fetch(
`${process.env.CLUSTER_API_URL}/users`
).then(res => res.json())
setData(result.data)
})
return (
<ul>
{data.map(user => (
<li key={user.id}>
<a href={user.url}>{user.name}</a>
</li>
))}
</ul>
)
}
export default App
Add .env*
 files to .gitignore
Environment variable files should not be committed to Git as they often contain secrets which are not safe to add to Git. Instead, add .env.*
 to your .gitignore
 file and setup the environment variables manually locally.
Python test
# Python program to swap two variables
x = 5
y = 10
# To take inputs from the user
#x = input('Enter value of x: ')
#y = input('Enter value of y: ')
# create a temporary variable and swap the values
temp = x
x = y
y = temp
print('The value of x after swapping: {}'.format(x))
print('The value of y after swapping: {}'.format(y))
