#Example of usage

If your application is using csrf token like authentication like in django made app you need to set the token before using the library, otherwise the requests won't be authorized

Making simple GET request:

url - required, params - optional

    const url = 'https://cat-fact.herokuapp.com/facts/random';
    const url_params = {
        name: 'Jenny',
        age: 4,
    }
    
    const success = (response) => {
        console.log('success', response);
    };
    
    const error = (error) => {
        console.log('error', error);
    };

    makeGetRequest({
        url,
        params: url_params,
        successCallback: success,
        errorCallback: error
    });

Making simple POST request:

url - required, data - optional

    const url = 'https://cat-fact.herokuapp.com/facts/random';
    const postData = {
        name: 'Jenny',
        age: 4,
    };
    
    const successCallback = (response) => {
        console.log('success', response);
    };
    
    const errorCallback = (error) => {
        console.log('error', error);
    };
    
    makePostRequest({
        url,
        data: postData,
        successCallback,
        errorCallback
    });

Resolve multiple GET calls:

requestsOptions - required and must be in a form of an array of objects with url parameter in them

    const randomCatRequestOptions = [
        {
            url: 'https://cat-fact.herokuapp.com/facts/random'
        },
        {
            url: 'https://cat-fact.herokuapp.com/facts/random'
        },
        {
            url: 'https://cat-fact.herokuapp.com/facts/random'
        },
    ];

    const successCallback = (response) => {
        console.log('success', response);
    };
    
    const errorCallback = (error) => {
        console.log('error', error);
    };

    resolveAllGetRequests({
        requestsOptions: randomCatRequestOptions,
        successCallback,
        errorCallback
    });
