Now you can import http file as ESM module and make HTTP request with following frameworks/tools support:

  • esbuild
  • Rollup.js
  • Webpack
  • Vite.js
  • Bun

Attention: now httpfile plugin use global fetch API to make HTTP request, so please use Nodejs 18.x or node-fetch.

For example, you have demo.http file wit following code:

### get my ip
//@name myIp
User-Agent: curl/7.47.0

### post test
//@name postTest
POST https://{{host}}/post
User-Agent: curl/7.47.0
Content-Type: application/json

"name": "{{nick}}",
"age": 42,
"uuid": "{{$uuid}}",
"demo": "hi` morning"

And you can import demo.http file as ESM module, and http request names will be treated as function names. You can call remote HTTP service with function style instead of HTTP Client API.

import {myIp, postTest, graphqlSimple, graphqlDemo} from "./demo.http";

// simple http request
let response = await myIp();
console.log(await response.json());

// simple http post
response = await postTest({nick: "test", host: "", "uuid": "c8389930-1071-4b88-9676-30b9ba7f2343"});
console.log(await response.json());

GraphQL over HTTP support too.

Webpack loader for http file

If you use Webpack, you can use webpack-loader-httpfile to import http file.

  • Add dev dependency: npm install -D webpack-loader-httpfile
  • Modify webpack configuration(webpack.config.js) file to add httpfile loader and experiments.topLevelAwait as following:
const path = require('path');

module.exports = {
module: {
rules: [
test: /\.http$/,
use: [
loader: path.resolve(__dirname, 'node_modules/webpack-loader-httpfile/index.js'),
options: {
verbose: true
experiments: {
topLevelAwait: true

Bun loader plugin for http file

If you use Bun, you can use bun-plugin-httpfile to import http file.

  • Add dev dependency: npm install -D bun-plugin-httpfile
import { plugin } from "bun";

import httpfilePlugin from 'bun-plugin-httpfile';

// Usage
import {myIp} from "./index.http";
let response = await myIp();
console.log(await response.text());
