Advantages of using Axios:

Easy to Use: Axios is easy to use and can be integrated with any JavaScript application or framework.

Promise Based: Axios uses promises to handle asynchronous requests, making it easier to manage the data flow.

Interceptor Support: Axios allows you to intercept requests or responses before they are handled by the application. This can be useful for adding authentication tokens, logging requests, or handling errors.

Cross-Platform: Axios can be used in both client-side and server-side applications, making it a versatile choice for developers.

Supports JSON: Axios automatically parses JSON responses, which makes it easy to work with APIs that return JSON data.

Browser Compatibility: Axios works with all modern browsers, including Chrome, Firefox, Safari, and Edge.

Lightweight: Axios is a lightweight library that doesn't require any external dependencies.

Error Handling: Axios provides robust error handling capabilities, including timeouts, network errors, and HTTP errors.

Configurable: Axios is highly configurable and allows you to customize settings such as headers, timeouts, and response types.

Overall, Axios is a reliable and versatile library that simplifies the process of making HTTP requests in JavaScript applications.

Utility function for axios

First we should create a utility function to make frequent calls using axios library.

const makeRequest = async function(method, endpoint, body, header) {
        try {

            let url = urls.API_URL + endpoint;
            let res = null;

            if(method === apiRequest.GET) {
                res = await axios(
                        {
                            method:'get',
                            url:url,
                            data:body,
                            headers:header
                        }
                        ).then((resp)=>{return resp})
                return res;
            }
            else if(method === apiRequest.POST) {
                res = await axios.post(url=url, data=body, {headers:header})
                        .then((resp)=>{return resp});
                return res;
            }
            else if(method === apiRequest.PUT) {
                res = axios.put(url=url, data=body, {headers:header})
                    .then((resp)=>{return resp});
                return res;
            }
            else if(method === apiRequest.DELETE) {
                res = axios.delete(url=url, data=body, {headers:header})
                    .then((resp)=>{return resp});
                return res;
            }
        } catch (error) {
            self.errorException(exceptionMessage.API_REQUEST_EXCEPTION.format(method,url), error);
        }
    };

GET Request example

Using the utility function, we can make GET request in a single line. The headers and body can be passed as json objects.

const apiEntpoint = 'https://api.example.com/api/v1/customer'
let response = await self.makeRequest(apiRequest.GET, apiEndpoint, body, headers);
console.log(response.data)

POST request example

POSt request can be made using the same function.

const apiEntpoint = 'https://api.example.com/api/v1/customer'
let headers = {
                Content-Type: "application/json",
                apikey: "fjdsa9fu2398ujfdsfuslifys"
            }
let response = await self.makeRequest(apiRequest.POST, apiEndpoint, body, headers);
console.log(response.data)
