http requests in stenciljs

Question

How can I make http requests (GET / POST / PUT / DELETE) in StencilJS?

I tried using axios as follows: Did npm install axios --save and in the stencil component import axios from 'axios';. As soon as I call axios.get(...)I get the following error message:

---

[ ERROR ] bundling: node_modules/axios/lib/adapters/http.js, line: 4

A module cannot import itself

L3: var utils = require('./../utils');

L4: var settle = require('./../core/settle');

L5: var buildURL = require('./../helpers/buildURL');

---

I understand it might have to do with this issue: https://github.com/ionic-team/stencil/issues/98

However, any recommendations on how to get html requests work within a stencil component?

We can use the fetch API. It is browser native and does therefore not need an import. StencilJS also has a polyfill for it, so it works everywhere.

Thanks to @insanicae for pointing me to it.

Example:

import { Component, State } from '@stencil/core';

@Component({
  tag: 'app-profile',
  styleUrl: 'app-profile.css'
})
export class AppProfile {
  @State() name: string;

  componentWillLoad() {
    fetch('https://api.github.com/users/ErvinLlojku')
      .then((response: Response) => response.json())
      .then(response => {
        this.name = response['name'];
      });
  }

  render() {
    return [
      <ion-header>
        <ion-toolbar color="primary">
          <ion-buttons slot="start">
            <ion-back-button defaultHref="/" />
          </ion-buttons>
          <ion-title>Profile: {this.name}</ion-title>
        </ion-toolbar>
      </ion-header>,

      <ion-content padding>
        <p>My name is {this.name}.</p>

      </ion-content>
    ];
  }
}
