- The runtime config API in Nuxt is like a secret vault for all your confidential information, like API keys and sensitive data. 🤫
- You can expose your secret info to your Nuxt app, but make sure it's secure and stays private. 🔒
- With Nuxt's runtime config, you can access your private variables on the server side, but your public ones can be accessed on both the server and client side. 💻
- Remember, when configuring your runtime variables with environment variables, match the naming structure for a smooth operation. 🔄
- Nuxt's runtime config is a powerful tool, used wisely, it can keep your secrets safe and your app running smoothly. 😎

Overview 📊

Nuxt provides a runtime config API to expose configuration and secrets within our nux applications. This article will explore the purpose of the runtime config API and how to configure it effectively.

What is the Runtime Config API? 🚀

The runtime config API is used to expose environment variables and private tokens within your application. These can include sensitive information such as API keys, which need to be kept private.

Using the Runtime Config API ⚙️

In a Nuxt 3 application, the runtime config API can be utilized to securely access and use API keys for making API requests. This can be achieved by declaring and setting variables within the runtime config, and then accessing them on the server or client side of the application.

"The runtime config API is a crucial tool for securely utilizing sensitive information within Nuxt applications."

Example Usage of Runtime Config API 🌐

A server route can utilize a composable called useRuntime to access variables declared in the runtime config. This allows secure usage of API keys within API requests.

Implementation in Nuxt 3 Application 🖥️

To use the runtime config API in a Nuxt 3 application, the nuxt.config.js file needs to define the runtime config property. This is where variables such as API keys are declared and set.

Example:

module.exports = {
  publicRuntimeConfig: {
    apiKey: process.env.API_KEY
  }
}

Configuring with Environment Variables ⚙️

It is recommended to configure runtime variables with environment variables to ensure security. Naming conventions for environment variables should match the structure used in the runtime config to avoid any issues.

Environment Variables
Variable Name
NU_CORE_API_KEY
NU_PUBLIC_API_BASE

"Configuring runtime variables with environment variables is crucial for maintaining security in Nuxt applications."

Additional Usage 📦

The runtime config API can also be utilized within middleware and when defining plugins in a Nuxt application.

Key Takeaways 🚀

  • Private runtime configuration is only accessible on the server side.
  • Public variables can be accessed on both the server and client side.
  • Matching naming structures for environment variables and runtime config is essential for seamless integration.

Conclusion 📝

The runtime config API in Nuxt 3 is a powerful tool for securely handling sensitive information within applications. By carefully configuring and utilizing this feature, developers can ensure the privacy and security of their application's data.

🎯 Key Takeaways
Private config only on server side
Public variables accessible on both sides
Matching naming structures for seamless integration
