TypeScript example

Importing types

axios provides a number of TypeScript types that you can use to type your requests and responses. To import these types, you can use the import statement. For example you can access the AxiosRequestConfig and AxiosResponse types like so:

import { AxiosRequestConfig, AxiosResponse } from "axios";

Implementing types

By using the types provided by axios, you can type your requests and responses. For example, you can type a request like so:

import axios, { AxiosRequestConfig, AxiosResponse } from "axios";

type Post = {
  userId: number;
  id: number;
  title: string;
  body: string;
};

const getPosts = async (postId: number): Promise<AxiosResponse<Post>> => {
  return axios().get("https://jsonplaceholder.typicode.com/posts", {
    params: {
      postId,
    },
  });
};

This will ensure that the response from the getPosts function is of type AxiosResponse<Post>, where Post is the type of the response data. This can help you catch errors early and ensure that your code is type safe.
