React Query database plugin: deep integration with containerization technology

React Query database plug-in: Deep integration with containerization technology, specific code examples are required

Introduction:
With the continuous development of front-end development, data management and status management become very important. React Query is a powerful data management tool that can help us handle data acquisition, caching, mutation and other tasks. However, in actual projects, we often need to store data in the database for persistence.

This article will introduce how to use the React Query database plug-in to achieve deep integration with containerization technology. We'll use Docker containers and MongoDB databases as examples.

Step 1: Create a Docker container
First, we need to create a Docker container to run the MongoDB database. You can use the following command to start a MongoDB container:

docker run -d -p 27017:27017 --name mongodb_container mongo

In the above command, we created a container named mongodb_container based on the official MongoDB image, and mapped the container's 27017 port to the host's 27017 port.

Step 2: Install the React Query database plug-in
In the project directory, use the following command to install the React Query database plug-in:

npm install react-query react-query-db-plugin

Step 3: Configure the database connection
In the project Create a file named db.js in the root directory of Database object, and the MongoDB address is specified as

http://localhost:27017

. Step 4: Use the database plugin in the componentNow we can use the React Query database plugin in the React component. Here is a simple example:

import { createDb } from 'react-query-db-plugin';

const options = { endpoint: 'http://localhost:27017' };
export const db = createDb(options);

In the above code, we use the

useQuery
hook to get the data in the

todos

collection and use useMutation Hook to create a new todo. Conclusion: By using the React Query database plugin, we can easily integrate the power of React Query with the MongoDB database. In this article, we show how to use Docker containers and the MongoDB database as examples, and provide concrete code examples to achieve deep integration. I hope this article can help you better understand and use the React Query database plugin.
