Env local not working nextjs

Configuring Next.js Env Local: Environment Variables in Next.js

Environment variables are essential tools for developers working with Next.js. They allow you to configure your application for different environments, such as development, testing, and production, without hardcoding sensitive data into your codebase. By using environment variables, you can keep your API keys, database connection strings, and other sensitive information secure.

This blog will guide you through the process of configuring the Next.js env local variables, ensuring that your application runs smoothly and securely across all environments.

What are Environment Variables?

Environment variables are key-value pairs that can be used to provide configurations for different application running environments. They are defined outside of the actual application code and can influence the behavior of an application. For instance, you might use environment variables to store API keys, database connection strings, or other sensitive data that should not be hardcoded into your application.

Why Use Environment Variables?

Using environment variables offers several benefits:

• Security: Keep sensitive data like A

How to use environment variables in Next.js

Next.js comes with built-in support for environment variables, which allows you to do the following:

Warning: The default template ensures all files are added to your . You almost never want to commit these files to your repository.

Loading Environment Variables

Next.js has built-in support for loading environment variables from files into .

This loads , , and into the Node.js environment automatically allowing you to use them in Next.js data fetching methods and API routes.

For example, using :

Loading Environment Variables with

If you need to load environment variables outside of the Next.js runtime, such as in a root config file for an ORM or test runner, you can use the package.

This package is used internally by Next.js to load environment variables from files.

To use it, install the package and use the function to load the environment variables:

Then, you can import the configuration where needed. For example:

Environment Variables Not Getting Passed to NextJS 12 API Routes

Hi all,

I’m considering moving from Heroku to Netlify for my NextJS 12 app. I have a few NextJS API routes in my app, one of which depends on an API key/secret that I store as an environment variable (ESV_API_KEY).

App URL: https://staging.faithdashboard.com/
API Route (that should work): https://staging.faithdashboard.com/api/widgets/bible-verse?q=ps23.1
Relevant Code: faith-dashboard/bible-verse.ts at main · caleb531/faith-dashboard · GitHub

Now here’s the problem:

Locally, my environment variable is stored in a gitignore’d file so it’s not committed publicly.
On Heroku, I can set this environment variable in the dyno settings, and it gets passed through to my API route without any additional configuration.
But on Netlify, my API route is showing the environment variable (ESV_API_KEY) as undefined, even though I’ve defined it in the Netlify Deploy Settings (screenshot below). And I have made sure to redeploy after setting the env variable, but still no luck. You can see the behavior if you visit the API route URL above

Now, I have read [Support Guide] Using environment variables on Netlify corre

Nextjs not picking up env values

Component19551

I have a NextJS instance that expects the to be set in the environment prior to running. It is being set via Project settings. I can SSH into the container and verify this. I am also setting the variable inside file, but it isn’t being picked up anywhere.

Component19552

After explicitly providing the missing variable names as variables worked. I am relieved but also absolutely baffled.

Component19553

When I SSH into the container and manually start then open another terminal to SSH and start the Cypress tests. It fails with the same errors complaining that variables in aren’t being set.

Component19554

It seems like doesn’t work either.

But this is how I fixed my issue:

Is it possible that it needs to be vs ?

If you have it set in your project settings and can echo it out when you run a job via ssh, then you shouldn’t need to source the config.

I tried both ways. It still failed.

So you are creating your dream app using Next. js which you have always wanted to build. Let me be honest, learning next.js is one of the best decisions you have taken! So let’s understand the problem and solve it.

Next.js is undoubtedly one of the most versatile and robust React.js full-stack frameworks ever created. Its popularity skyrocketed like anything. One of its unique features is that it brings the concept of server-side components into the picture. We can possess two types of components in the next.js application: server-side components and client-side components. That is the key to the fix to this problem.

You could possess followed a Next.js YouTube tutorial or GitHub code that makes use of environment variables. But for some reason, it says that the environment variable is undefined. But why?

For versions of Next.js prior to 9.4:

The .env variables are essentially accessible on the server side in the case of Next.js. To access this .env variable on the client side we need to declare the .env variables in the next.config.js.
