Discuss how to remove APIs from Vue production environments

Vue is a progressive framework for building user interfaces. In many Vue projects, we need to use APIs to get data. When we build Vue applications, we usually need to access APIs to get data and display it to the user. However, in a production environment, accessing the API may be unnecessary and may even be dangerous. In this article, we will discuss how to remove API in Vue production environment.

1. Using API in the Vue development environment

In the Vue development environment, we often use libraries such as axios to send HTTP requests to obtain data. This is because in a development environment we need to get data quickly and debug it. Using the API in development mode is very helpful. For example, when we use Vue to create a Todo list, we need to access the API to get the task list data.

In a Vue project, we usually create a separate js file to place API requests. In this API file, we will define a function that will send an HTTP request to the server and return a Promise object to obtain API data.

2. Removing the API in the Vue production environment

Similar to using the API in the development environment, we need to remove the API in the production environment. This is because in a production environment we need to deploy the application to multiple servers. In this case, we cannot use a certain API address fixedly. We need to use different API addresses based on the deployment of different servers.

So when we use the Vue application in a production environment, we need to perform the following steps:

1) Remove the API address from the hardcoding

First, We need to remove the API address from being hardcoded. We cannot hard-code the API address, but manage the address through the configuration file. In the Vue project, we can use .env files to manage these configuration parameters. We can define the API address in the .env file and then use the parameter in the application.

Add the following content in the .env file:

VUE_APP_API_URL=/api

Use this parameter in the application.

axios.get(`${process.env.VUE_APP_API_URL}/todos`)
  .then(response => {
    this.todos = response.data;
  });

2) Use Nginx as a reverse proxy

We know that in a Vue application, we cannot directly access the API. We need to get API data through the server. In a production environment, we can use Nginx as a reverse proxy. Reverse proxy refers to forwarding client requests to the backend server and returning API data to the client. In this case, the Vue application will access the API through a reverse proxy server.

Add the following content to the Nginx configuration file:

location /api {
  proxy_pass http://api-service;
}

This configuration specifies a /api proxy that forwards requests to http://api-service.

3) Use Docker containerization to deploy

Finally, we can use Docker containerization to deploy the Vue application. Containerization is a technology widely used in production environments. When we use Docker containerization to deploy a Vue application, we can deploy and run the container on multiple nodes and set a different API address in each container.

The benefit of Docker containerized deployment of Vue applications is that it can automatically manage application dependencies and speed up the application deployment process.

Conclusion

In a Vue application, accessing the API is very necessary, but using the API in a production environment can be dangerous. In order to use the Vue application safely in a production environment, we need to remove the API, use Nginx as a reverse proxy, and finally use Docker containerization to deploy the Vue application. These measures ensure that our applications run more securely and efficiently in production environments.
