VisualizaçõesHow to set the response type using axios with Javascript and JSDocs?
My API has a response as follows:
{
"foo": "bar",
"bar": "foo"
}
So I've created the response type using JSDocs as follows:
/**
* typedef {Object} AwesomeAPIResponse
* property {string} foo
* property {string} bar
*/
So, I'm calling my API using Axios with a post request:
const axios = require('axios').default
const someFunction = async () => {
const result = await axios.post(MY_API_URL, data, {
headers: { ... },
method: 'post'
})
return result
}
So far, so good, but the type of my response is AxiosResponse<any>, and I want it to be AxiosResponse<AwesomeAPIResponse>. I know I can achieve this by using TypeScript generics, but I'm not allowed to use TS and I don't want to return any as type. Is it possible to do something like this?

JSDoc is just used for type hinting for the IDE it can't be used in the way you're trying to.
The only way to return a "AwesomeAPIResponse" is by creating a class with that definition
class AwesomeAPIResponse {
constructor(foo, bar) {
this.foo = foo;
this.bar = bar;
}
}
and then returning a new instance of it based on the result
const someFunction = async () => {
const result = await axios.post(MY_API_URL, data, {
headers: { ... },
method: 'post'
})
const {foo, bar} = result;
return new AwesomeAPIRespone(foo, bar);
}

This works in VSCode.
/**
* @typedef {Object} Comment
* @property {number} id The PK.
* @property {number} postId The FK of the post the comment is related to.
* @property {string} body The comment's content.
*/
/**
* @typedef {import("axios").AxiosResponse<Comment>} CommentResponse
*/
/**
*
* @param {number} id The primary key of the comment to find.
* @returns {Promise<CommentResponse>}
*/
async function findCommentById(id) {
return axios.get(`https://jsonplaceholder.typicode.com/comments/${id}`);
}
const commentRes = await findCommentById(5);
console.log(commentRes.data.body);
Warning: Trying to avoid having to import each time by doing this did not work: @typedef {import("axios").AxiosResponse} AxiosRes -> AxiosRes<YourDataType>
