fetch-lite

A lightweight module to send HTTP(s) requests from Node.js.

• Not dependent on any third party modules.
• Purely based on Node.Js http.request client.
• Written in less than 30 lines. 😳
• Implements just the fetch() function and nothing else.
• Returns Promise (so works with async/await).

Whats missing?

• File Upload (multipart/form-data)
• Streaming.

Install

Install using npm.

npm install --save fetch-lite

OR Using yarn.

yarn install --save fetch-lite

Usage

The idea of fetch-lite is to create a minimal version of fetch() API described here. A basic GET request is shown below.

const fetch = require('fetch-lite');
 
fetch('https://httpbin.org/get')
.then(response => console.log(response))
.catch(err => console.error(err));

Using async/await.

(async () => {
    const response = await fetch('https://httpbin.org/get');
    console.log(response);
})();

Post

Posting a post body.

fetch('http://httpbin.org/post', {
    method: 'POST',
    body: {
        hello: 'world'
    }
})
.then(response => console.log(response))
.catch(err => console.error(err));

Posting a JSON body.

fetch('http://httpbin.org/post', {
    method: 'POST',
    body: {
        hello: 'world'
    },
    headers: {
        'content-type': 'application/json'
    }
})
.then(response => console.log(response))
.catch(err => console.error(err));

Posting a Buffer.

fetch('http://httpbin.org/post', {
    method: 'POST',
    body: Buffer.from("Hello World")
})
.then(response => console.log(response))
.catch(err => console.error(err));

Basic auth

fetch('https://httpbin.org/basic-auth/user/passwd', {
    auth: "user:passwd"
})
.then(response => assertEq(response.status, 200))
.catch(err => breakWithErr(err));
