- 0️⃣ Zero-Config Setup
- 🔒 SSL Support (HTTPS by default)
- 🛣️ Auto HTTP-to-HTTPS Redirection
- ✏️
/etc/hosts
Management - 🧼 Clean URLs (removes
.html
extension) - 🤖 CLI & Library Support
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 CleanupConfig {
hosts: boolean // clean up /etc/hosts, defaults to false
certs: boolean // clean up certificates, defaults to false
}
export interface ProxyConfig {
from: string // domain to proxy from, defaults to localhost:5173
to: string // domain to proxy to, defaults to rpx.localhost
cleanUrls?: boolean // removes the .html extension from URLs, defaults to false
https: boolean | TlsConfig // automatically uses https, defaults to true, also redirects http to https
cleanup?: boolean | CleanupConfig // automatically cleans up /etc/hosts, defaults to false
start?: StartOptions
verbose: boolean // log verbose output, defaults to false
}
const config: ProxyOptions = {
from: 'localhost:5173',
to: 'rpx.localhost',
cleanUrls: true,
https: true,
cleanup: false,
start: {
command: 'bun run dev:docs',
lazy: true,
}
}
startProxy(config)
In case you are trying to start multiple proxies, you may use this configuration:
// rpx.config.{ts,js}
import type { ProxyOptions } from '@stacksjs/rpx'
import os from 'node:os'
import path from 'node:path'
const config: ProxyOptions = {
https: { // https: true -> also works with sensible defaults
caCertPath: path.join(os.homedir(), '.stacks', 'ssl', `rpx.localhost.ca.crt`),
certPath: path.join(os.homedir(), '.stacks', 'ssl', `rpx.localhost.crt`),
keyPath: path.join(os.homedir(), '.stacks', 'ssl', `rpx.localhost.crt.key`),
},
cleanup: {
hosts: true,
certs: false,
},
proxies: [
{
from: 'localhost:5173',
to: 'my-app.localhost',
cleanUrls: true,
start: {
command: 'bun run dev',
cwd: '/path/to/my-app',
env: {
NODE_ENV: 'development',
},
},
},
{
from: 'localhost:5174',
to: 'my-api.local',
},
],
verbose: true,
}
export default 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 rpx.config.ts
(or rpx.config.js
) file and it will be automatically loaded when running the reverse-proxy
command.
// rpx.config.{ts,js}
import type { ProxyOptions } from '@stacksjs/rpx'
import os from 'node:os'
import path from 'node:path'
const config: ProxyOptions = {
from: 'localhost:5173',
to: 'rpx.localhost',
https: {
domain: 'rpx.localhost',
hostCertCN: 'rpx.localhost',
caCertPath: path.join(os.homedir(), '.stacks', 'ssl', `rpx.localhost.ca.crt`),
certPath: path.join(os.homedir(), '.stacks', 'ssl', `rpx.localhost.crt`),
keyPath: path.join(os.homedir(), '.stacks', 'ssl', `rpx.localhost.crt.key`),
altNameIPs: ['127.0.0.1'],
altNameURIs: ['localhost'],
organizationName: 'stacksjs.org',
countryName: 'US',
stateName: 'California',
localityName: 'Playa Vista',
commonName: 'rpx.localhost',
validityDays: 180,
verbose: false,
},
verbose: false,
}
export default config
Then run:
./rpx start

Troubleshooting
SSL Certificate Issues
If you're experiencing SSL certificate issues when using RPX (like "Your connection is not private" browser warnings):
Automatic Certificate Trust: RPX automatically attempts to trust certificates during setup with a single password prompt. This works for most users.
Use the certificate fix utility: If you still see certificate warnings, run our automated certificate fixer:
bun scripts/fix-certs.js
This script will:
- Detect your operating system
- Find all RPX certificates
- Install them to the appropriate system trust stores
- Provide browser-specific instructions
Browser Workaround:
- Chrome/Edge/Arc: Type
thisisunsafe
on the warning page (you won't see what you're typing) - Firefox: Click "Advanced" then "Accept the Risk and Continue"
- Safari: Click "Show Details", then "visit this website"
- Chrome/Edge/Arc: Type
Note: After trusting certificates, restart your browser for changes to take effect.
