A Better Developer Experience

A zero-config reverse proxy for local development with SSL support, custom domains, and more.

Features

• Simple, lightweight Reverse Proxy
• Custom Domains (with wildcard support)
• Zero-Config Setup
• SSL Support (HTTPS by default)
• Auto HTTP-to-HTTPS Redirection
• Self /etc/hosts Management

Install

bun install -d @stacksjs/rpx

Get Started

There are two ways of using this reverse proxy: as a library or as a CLI.

Library

Given the npm package is installed:

import type { TlsConfig } from '@stacksjs/rpx'
import { startProxy } from '@stacksjs/rpx'

export interface ReverseProxyConfig {
  from: string // domain to proxy from, defaults to localhost:3000
  to: string // domain to proxy to, defaults to stacks.localhost
  https: boolean | TlsConfig // automatically uses https, defaults to true, also redirects http to https
  etcHostsCleanup?: boolean // automatically cleans up /etc/hosts, defaults to false
  verbose: boolean // log verbose output, defaults to false
}

const config: ReverseProxyOptions = {
  from: 'localhost:3000',
  to: 'my-project.localhost',
  https: true,
  etcHostsCleanup: true,
}

startProxy(config)

CLI

rpx --from localhost:3000 --to my-project.localhost
rpx --from localhost:8080 --to my-project.test --keyPath ./key.pem --certPath ./cert.pem
rpx --help
rpx --version

Configuration

The Reverse Proxy can be configured using a reverse-proxy.config.ts (or reverse-proxy.config.js) file and it will be automatically loaded when running the reverse-proxy command.

// reverse-proxy.config.{ts,js}
import type { ReverseProxyOptions } from '@stacksjs/rpx'
import os from 'node:os'
import path from 'node:path'

const config: ReverseProxyOptions = {
  from: 'localhost:5173',
  to: 'stacks.localhost',
  https: {
    domain: 'stacks.localhost',
    hostCertCN: 'stacks.localhost',
    caCertPath: path.join(os.homedir(), '.stacks', 'ssl', `stacks.localhost.ca.crt`),
    certPath: path.join(os.homedir(), '.stacks', 'ssl', `stacks.localhost.crt`),
    keyPath: path.join(os.homedir(), '.stacks', 'ssl', `stacks.localhost.crt.key`),
    altNameIPs: ['127.0.0.1'],
    altNameURIs: ['localhost'],
    organizationName: 'stacksjs.org',
    countryName: 'US',
    stateName: 'California',
    localityName: 'Playa Vista',
    commonName: 'stacks.localhost',
    validityDays: 180,
    verbose: false,
  },
  verbose: false,
}

export default config

In case you are trying to start multiple proxies, you may use this configuration:

// reverse-proxy.config.{ts,js}
import type { ReverseProxyOptions } from '@stacksjs/rpx'
import os from 'node:os'
import path from 'node:path'

const config: ReverseProxyOptions = {
  https: { // https: true -> also works with sensible defaults
    caCertPath: path.join(os.homedir(), '.stacks', 'ssl', `stacks.localhost.ca.crt`),
    certPath: path.join(os.homedir(), '.stacks', 'ssl', `stacks.localhost.crt`),
    keyPath: path.join(os.homedir(), '.stacks', 'ssl', `stacks.localhost.crt.key`),
  },

  etcHostsCleanup: true,

  proxies: [
    {
      from: 'localhost:5173',
      to: 'my-app.localhost',
    },
    {
      from: 'localhost:5174',
      to: 'my-api.local',
    },
  ],

  verbose: true,
}

export default config

Then run:

./rpx start
