How to Add Process.env When Using Vite?

To add process.env variables when using Vite, you can create a .env file at the root of your project and define your environment variables there. These variables can then be accessed in your application using process.env.VARIABLE_NAME. Make sure to restart your Vite server after adding or modifying the .env file to ensure the changes take effect. Additionally, you can also specify different environment variables for different build modes (e.g., development, production) by creating .env files with corresponding suffixes (e.g., .env.development, .env.production).

How to set up process.env in Vite?

To set up process.env in Vite, you can follow the steps below:

1. Create a .env file in the root directory of your project. You can create different .env files for different environments such as .env.development, .env.production, etc.
2. Add your environment variables to the .env file using the format VARIABLE_NAME=variable_value. For example:

1
2

API_URL=https://api.example.com
API_KEY=123456789

1. Install the @types/node package if you haven't already:

1

npm install --save-dev @types/node

1. Use the import.meta.env object in your Vite configuration file (vite.config.js) to access the environment variables. For example:

1
2
3
4
5

export default {
  define: {
    'import.meta.env': JSON.stringify(dotenv.config().parsed) // Load the .env file
  }
}

1. In your Vite application code, you can access the environment variables using import.meta.env.VARIABLE_NAME. For example:

1
2

const apiUrl = import.meta.env.API_URL;
const apiKey = import.meta.env.API_KEY;

Make sure to restart your Vite dev server after making changes to the .env file for the changes to take effect.

How to debug process.env related issues in Vite?

To debug process.env related issues in Vite, you can follow these steps:

1. Check your .env files: Make sure you have the correct environment variables set in your .env files. Also, check if you have a .env.development or .env.production file depending on the environment you are running the Vite app in.
2. Verify Vite configuration: Check your vite.config.js file to see if the dotenv plugin is correctly configured to load environment variables from the .env files. You can also check the define option in the Vite configuration to ensure that process.env variables are correctly defined.
3. Print process.env variables: You can insert console.log(process.env) in your code to print out all the environment variables at runtime. This can help you identify if the process.env variables are loaded correctly.
4. Restart Vite server: Sometimes, changes in environment variables may not reflect in the Vite server immediately. Try restarting the Vite server to see if the new environment variables are picked up.
5. Use a debugger: If you are still facing issues, you can use a debugger to step through your code and see where the process.env variables are being accessed or manipulated incorrectly.

By following these steps, you should be able to debug process.env related issues in Vite successfully.

How to add process.env variables in a Vite project?

To add process.env variables in a Vite project, you can follow these steps:

1. Create a .env file in the root directory of your Vite project. Define your environment variables in this file in the format VITE_VARIABLE_NAME=variable_value.
2. Install the @types/node package if you haven't already by running npm install --save-dev @types/node.
3. In your Vite project, you can access these environment variables using import.meta.env.VITE_VARIABLE_NAME. For example:

1

console.log(import.meta.env.VITE_API_KEY);

1. You can also access these environment variables in your configuration files, such as vite.config.js, by using process.env.VITE_VARIABLE_NAME. For example:

1
2
3
4
5

export default {
  define: {
    'process.env': process.env,
  },
};

1. Start or build your Vite project as usual, and the environment variables defined in the .env file will be available throughout your project. Note that the environment variables should start with VITE_ to be accessible in the Vite project.

That's it! You have successfully added process.env variables in your Vite project.
