Usage

Typescript Class with default constructor

class Post{
    id: number = 0;
    userId: number = 0;
    title: string = '';
    body: string = '';
}

import Http from 'axios-typescript-response';

...

http
  .get<Post>("https://jsonplaceholder.typicode.com/posts/1", Post)
  .then((response) => console.log(response instanceof Post)) //output: true

//Calling the function without type parameter returns axios default function
http
  .get("https://jsonplaceholder.typicode.com/posts/1")
  .then((response) => console.log(response.data instanceof Post)) //output: false

Typescript Class with constructor

class Post{
    constructor(obj:any = {}){
        this.id = obj.id;
        this.userId = obj.userId;
        this.title = obj.title;
        this.body = obj.body;
    }

    id: number;
    userId: number;
    title: string;
    body: string;
}

import Http from 'axios-typescript-response';

...

http
  .get<Post>("https://jsonplaceholder.typicode.com/posts/1", Post, true)
  .then((response) => console.log(response instanceof Post)) //output: true

//Calling the function without type parameter returns axios default function
http
  .get("https://jsonplaceholder.typicode.com/posts/1")
  .then((response) => console.log(response.data instanceof Post)) //output: false

Use axios interceptors

import store from '../store/store';
import router from '../router/router';
import Http from 'axios-typescript-response';

Http.axiosInstance.interceptors.request.use(config => {
    debugger
    config.baseURL = store.getters.baseUrl;

    //Auth token
    const token = store.state.user!.token;
    
    if (token) {
        config.headers.Authorization = `Bearer ${token}`;
    }

    //Culture
    const lang = store.getters.Language;
    config.headers["Accept-Language"] = lang || 'bg';
    config.headers["Accept"] = '*/*';

    return config;
});

// Add a 401 response interceptor
Http.axiosInstance.interceptors.response.use(response => {
    return response;
}, function (error) {
    if (401 === error.response.status) {
        store.dispatch('logout').then(() => {
            router.push('/login');
        });
    } else {
        return Promise.reject(error);
    }
});

export default Http;
