Add headers HttpRequest in NestJS

Question

I'm trying to make a Http request in NestJS

As it's inspired from angular I jave append my Headers

import { Injectable, HttpService} from '@nestjs/common';
...
const headersRequest = new Headers();
headersRequest.append('Content-Type', 'application/json');
headersRequest.append('Authorization', `Basic ${encodeToken}`);

Then call the api

const result = await this.httpService.post(apiUrl, newDevice, { headers: headersRequest });

I get an error

ReferenceError: Headers is not defined

And when I ass Headers to import I get this message waring in VScode

Only a void function can be called with the 'new' keyword.

NestJS uses axios under the hood to make http requests, take a look at its documentation for request configuration:

https://github.com/axios/axios#request-config

Looks like there is no interface for headers, just pass a plain JS dictionary object:

const headersRequest = {
    'Content-Type': 'application/json', // afaik this one is not needed
    'Authorization': `Basic ${encodeToken}`,
};

const result = await this.httpService.post(apiUrl, newDevice, { headers: headersRequest });
