Axios Set Base Url React Native for API Call

Share post on

Axios set base URL React is essential when making API calls in modern mobile applications, especially when working with React Native. With a clean and efficient structure for your API calls, you can improve both performance and maintainability. One of the most widely used libraries for handling HTTP requests in React Native is Axios. Axios set base URL React functionality allows you to define a common URL for all requests, reducing repetitive code and making the API structure more organized. Axios simplifies the process of communicating with APIs and has numerous features that make it stand out, such as setting a base URL, handling request/response interceptors, and managing errors effectively. For developers looking to implement axios set base URL React, this feature is highly beneficial as it improves code clarity and centralizes API configuration. When working with APIs in React Native, efficiently managing API calls is crucial, and using Axios to set the base URL in React Native for API calls is a powerful technique to achieve this.

What is Axios?

Axios is a promise-based HTTP client designed for Node.js and browser applications, making it versatile for any JavaScript environment. It provides an easy-to-use API to handle HTTP requests, such as GET, POST, PUT, and DELETE. In React Native applications, using axios set base url react is a popular choice due to its straightforward syntax and built-in features, like interceptors, cancellation, and timeout handling. By implementing axios set base url react, developers can streamline their API interactions and enhance code organization, making their applications more efficient.

Why Set a Base URL in Axios?

When working with APIs in any application, it’s common to send multiple requests to the same API server. Instead of repeating the full API URL every time you make a request, you can use axios set base URL React to define a base URL. This will significantly reduce redundancy and help maintain a cleaner and more organized codebase. You only need to define the relative paths for API endpoints, making your code more modular and scalable.

For instance, instead of writing the full URL in every request, you can create a predefined instance of Axios with a base URL. By using axios set base URL React, it will automatically prepend the base URL to every subsequent request, saving your time and reducing potential errors in typing out long URLs repeatedly.

How to Set Up Axios with a Base URL in React Native

STEP 1 : installing Axios

Before we dive into setting the base URL, you need to install Axios in your React Native project:

After installation, you can start using Axios to handle your API calls.

STEP 2 : iImporting Axios and Setting up a Base URL

The next step is to import Axios into your React Native project and configure it with a base URL. This will be used for all API requests throughout your app.

Here, we use axios.create() to create a new instance of Axios and pass in a configuration object that includes the base URL. Now, any requests made with this Axios instance will automatically append the endpoint to the base URL.

STEP 3: Making API Requests

Once you’ve set up the base URL, you can start making requests without having to specify the full URL every time. Here’s an example of how to make GET and POST requests:

Notice that you only need to pass the relative URL, such as /users or /posts, and Axios automatically appends it to the base URL.

Main API Request Types

Now that you know how to set a base URL, let’s go over the different types of requests you can make with Axios.

GET vs POST Request Example

GET Request	POST Request
Fetch data from the server	Send new data to the server
`api.get('/data') .then(response => console.log(response.data)) .catch(error => console.error(error));`	`api.post('/data', { name: 'aishcosolutions' }) .then(response => console.log(response.data)) .catch(error => console.error(error));`

API Request Table

PUT Request	DELETE Request
Update existing data on the server	Remove data from the server
`api.put('/data/1', { name: 'consultancyashco' }) .then(response => console.log(response.data)) .catch(error => console.error(error));`	`api.delete('/data/1') .then(() => console.log('data deleted')) .catch(error => console.error(error));`

Error Handling Table

Error Handling
Handle errors from the server
`api.get('/data') .then(response => console.log(response.data)) .catch(error => console.error('An error occurred', error));`

Handling errors is crucial for creating a seamless user experience. With Axios, error handling is simplified with the .catch() block. You can log the error or show a user-friendly message to indicate that something went wrong.
