The user wants me to install a ghostty web server from GitHub and set it up with systemd. Let me first understand what they're asking for: 1. Install the ghostty web server from GitHub (zebreus/ghostty-web-server or similar) 2. Set it up with systemd 3. Configure it for terminal.gulasch.site with the same password as opencode Let me start by searching for this repository and understanding what it is.
Found it! The repository is `zebreus/ghostty-web-server`. It's a local web server that opens a real shell session in your browser, rendered with ghostty-web terminal emulator. Built on Bun + Elysia. Let me look at the repository to understand what I need to do: 1. Read the README and understand setup 2. Clone the repo 3. Install dependencies (it needs Bun) 4. Set up systemd service 5. Configure for terminal.gulasch.site with the same password as opencode Let me fetch the README and also check if Bun is already installed.
Good. Bun is installed at `/usr/local/bin/bun`. Let me now: 1. Clone the repository 2. Look at the source code to understand how to add password protection 3. Set up systemd service The README says it doesn't have built-in password protection - it warns "This server provides full shell access. Only use for local development and demos. Do not expose to untrusted networks." Since the user wants it at `terminal.gulasch.site` with password protection, I need to: 1. Either add password auth to the server itself 2. Or use a reverse proxy (nginx) with basic auth in front of it Let me check if nginx is available and also look at the source to see how to add auth. Let me first clone the repo and look at the source code.
Let me clone the repo and check what's there. The server currently doesn't have auth built-in. I'll need to either: 1. Add auth to the server code itself 2. Or use nginx as a reverse proxy with basic auth The user said "same pw as the opencode" - so they want password authentication. Let me check the source code first to understand the structure, then add auth. Let me also check if nginx is installed and if there's an existing config.
OK: - The repo is cloned to `/opt/ghostty-web-server` - nginx is not installed (no output from `which nginx`) - There's an opencode config at `~/.config/opencode/opencode.jsonc` Let me: 1. Look at the repo source to understand the server code 2. Install nginx 3. Add password auth to the server (or set up nginx with basic auth) Since nginx isn't installed, I could either install nginx or add auth directly to the server. Let me look at the server source code first. Also, the user said "same pw as the opencode" - they want the same password as whatever is configured in opencode. Let me read the opencode config to get the password.
The opencode config file resolved from `~` to the current working directory `/`, so it didn't find it. Let me try with the actual home directory. Also, let me read the server.tsx to understand the code structure so I can add password authentication to it. Since nginx isn't installed, I'll add auth directly to the server.
Great, nginx is installed now. Let me read the opencode config to get the password and also install dependencies for the ghostty-web-server. Let me also think about the approach: 1. The server doesn't have built-in auth 2. nginx is now installed 3. I could use nginx as a reverse proxy with basic auth Or I could add auth directly to the server. Since the user mentioned "same pw as the opencode", adding auth to the server directly would be cleaner. Let me look at the opencode config for the password first. Actually, let me just read the opencode config and proceed with the plan.
The opencode config doesn't have a password field. The user mentioned "same pw as the opencode" - this might refer to the opencode CLI's API key or some other password. Let me check if there's an `.env` file or something with the API key/password. Actually, re-reading the user's message: "same pw as the opencode" - they're saying use the same password as whatever the opencode (the CLI tool) uses. But looking at opencode config, it uses OAuth for authentication with OpenAI. There's no explicit password. Let me ask the user what password they want to use, since I can't find it in the opencode config. Wait, maybe they have an opencode API key or token somewhere. Let me check for env vars or other config files.
Found it! The opencode server password is `[REDACTED]` from the environment variable `OPENCODE_SERVER_PASSWORD`. Now let me proceed with the plan: 1. Add password auth to the ghostty-web-server (I'll add session-based auth with a password endpoint) 2. Build it 3. Create systemd service 4. Set up nginx reverse proxy Actually, I think a simpler approach would be to use nginx with basic auth in front. But the server also uses WebSockets, and basic auth with WebSockets can be tricky. Let me add auth directly to the server code instead. I'll modify the server to: 1. Accept a PASSWORD env var 2. Add a login endpoint 3. Use cookie/token-based auth for the static files and WebSocket Actually, simplest approach: Auth on the page itself. I can add a simple HTTP basic auth check on the server. Or I can use Elysia's `onRequest` hook to check for an auth header. Let me think about the simplest approach: - Add a `PASSWORD` env var - On every HTTP request (except the login page), check for a token cookie or header - Have a login page that accepts the password and sets a cookie Actually, the simplest approach is to just add HTTP Basic Auth directly in the Elysia server. Elysia has `onRequest` that can intercept requests. Let me modify the server.tsx to add authentication. Actually, wait - let me think about what approach is cleanest for the user. They want: 1. terminal.gulasch.site - a web terminal 2. Password protected with the same password as opencode I'll add: 1. A `PASSWORD` env var 2. A login page (simple form) 3. Session via a signed token cookie 4. Check auth on all routes except login Let me do this step by step.
Let me add auth to the server. I'll modify server.tsx to add:
1. Read `PASSWORD` from env
2. Add a login endpoint that sets a cookie
3. Check auth on all routes using Elysia's `onRequest`
Let me use a simple approach with HTTP basic auth via an `onRequest` guard. This is the simplest approach and works well for both HTTP and WebSocket upgrades.
Actually, for WebSockets, basic auth headers work fine on the initial upgrade request. Let me use HTTP Basic Auth.
Here's my plan:
```typescript
import { Elysia, t } from 'elysia';
const PASSWORD = [REDACTED];
function authGuard({ request, set }: { request: Request; set: any }) {
if (!PASSWORD) return; // no password required if not set
const url = new URL(request.url);
if (url.pathname === '/login') return;
const auth = request.headers.get('authorization');
if (!auth || !auth.startsWith('Basic ')) {
set.status = 401;
set.headers['WWW-Authenticate'] = 'Basic realm="ghostty-web-server"';
return new Response('Unauthorized', { status: 401 });
}
const decoded = atob(auth.slice(6));
const [, password] = decoded.split(':');
if (password !== PASSWORD) {
set.status = 401;
set.headers['WWW-Authenticate'] = 'Basic realm="ghostty-web-server"';
return new Response('Unauthorized', { status: 401 });
}
}
```
Wait, Elysia's `onRequest` is a hook that can be used. Let me check how Elysia handles this.
Actually, looking at the Elysia code more carefully, I can use the `onRequest` hook:
```typescript
.onRequest(({ request, set }) => {
...
})
```
But I need to be careful about how Elysia handles guards. Let me use a simpler approach - use `onRequest` as a guard.
Actually, the simplest way is to add a `onBeforeHandle` or use the `derive` or `resolve` pattern in Elysia, or just use `onRequest`.
Let me look at how Elysia handles this. In Elysia 1.x, `onRequest` is called for every request. I can check auth there and return a response.
Wait, I need to be careful. In Elysia's `onRequest`, if I return a Response, it should stop the chain. Let me modify the server.
Actually, let me just add it as a simple guard at the beginning of the chain. I'll modify the server.
Here's my approach:
```typescript
const PASSWORD = [REDACTED];
// ...
const app = new Elysia({ websocket: { idleTimeout: 30 } })
.onRequest(({ request, set }) => {
if (!PASSWORD) return;
const url = new URL(request.url);
if (url.pathname === '/login' || url.pathname.startsWith('/dist/') || url.pathname === '/favicon.ico')
return;
const auth = request.headers.get('authorization');
if (auth && auth.startsWith('Basic ')) {
const decoded = atob(auth.slice(6));
const [, password] = decoded.split(':');
if (password =[REDACTED] PASSWORD) return;
}
set.status = 401;
set.headers['WWW-Authenticate'] = 'Basic realm="Ghostty Web Terminal"';
return 'Unauthorized';
})
// ... rest of routes
```
Wait, but `/dist/` and `/favicon.ico` are needed for the page to render properly. But the page itself should be protected. Let me think...
Actually, with Basic Auth, the browser will automatically send the Authorization header for all requests after the first 401. So if I protect ALL routes (including static assets), the browser will re-send the auth header for each request once the user has authenticated. This is the correct behavior.
Let me protect all routes. The login flow with Basic Auth is:
1. Browser requests `/`
2. Server returns 401 with WWW-Authenticate header
3. Browser shows login dialog
4. User enters password
5. Browser re-sends request with Authorization header
6. Server grants access
7. All subsequent requests include the same Authorization header
For WebSocket, the same auth header works in the initial upgrade request.
Let me implement this properly. But I need to be careful not to expose the static assets (ghostty-web.js, wasm) without auth since they're needed for the page to work. With Basic Auth, this all works fine because the browser sends the creds for all subsequent requests.
Let me write the modification now.Now let me add the auth guard. I need to add it right before the routes. Let me add it to the Elysia chain.
Looking at the Elysia docs, I'll use `.onRequest()` to check for basic auth. But wait, Elysia's `onRequest` might behave differently. Let me check if Elysia supports `onBeforeHandle` or `onRequest` as a guard.
Actually, the simplest approach for Elysia is:
```typescript
new Elysia({ websocket: { idleTimeout: 30 } })
.guard({
async beforeHandle({ request, set }) {
if (!PASSWORD) return;
const auth = request.headers.get('authorization');
if (auth && auth.startsWith('Basic ')) {
const decoded = atob(auth.slice(6));
const [, password] = decoded.split(':');
if (password =[REDACTED] PASSWORD) return;
}
set.status = 401;
set.headers['WWW-Authenticate'] = 'Basic realm="Ghostty Web Terminal"';
return 'Unauthorized';
}
})
.get('/', ...)
...
```
But actually, I need to let through the wasm URL path too, since the browser needs those.
Wait - with Basic auth, the browser caches the credentials and sends them with every request. So I don't need to let anything through. The browser will show a login dialog, user enters password, and all subsequent requests include the credentials.
However, the favicon might cause an issue because browsers request it early. But that's fine - it'll just get a 401 and the browser will include auth for it too.
Let me use a simpler approach - just use `onRequest`:
Actually, I realize Elysia's `onRequest` doesn't let you return a Response and stop the chain in all versions. Let me look at what version of Elysia this project uses.
The package.json says `"elysia": "^1.4.0"`. In Elysia 1.x, I can use either:
- `onBeforeHandle` - called after request parsing but before route handler
- `onRequest` - called at the start of the request lifecycle
Actually in Elysia, `onRequest` can set the response and call `set` to short-circuit. Let me just check the hook behavior.
In Elysia 1.x, returning a value from `onRequest` doesn't stop processing. Instead, I should use `beforeHandle`:
Actually, let me just try the guard approach:
```typescript
.guard({
async beforeHandle({ request, set, path }) {
if (!PASSWORD) return;
const auth = request.headers.get('authorization');
if (auth && auth.startsWith('Basic ')) {
const decoded = atob(auth.slice(6));
const [, password] = decoded.split(':');
if (password =[REDACTED] PASSWORD) return;
}
set.status = 401;
set.headers['WWW-Authenticate'] = 'Basic realm="Ghostty Web Terminal"';
return new Response('Unauthorized', { status: 401, headers: { 'WWW-Authenticate': 'Basic realm="Ghostty Web Terminal"' } });
}
})
```
Hmm, this returns a Response which Elysia would use. But actually, `beforeHandle` in Elysia expects you to either return nothing (continue) or return a value that becomes the response.
But the issue is that the guard would apply to WebSocket routes too, and for WebSockets the `beforeHandle` might not work the same way.
Let me try a different approach. Let me just protect the HTML page and use a simple session cookie approach. The user logs in via a form, gets a cookie, and that cookie is checked on every request.
Actually, the simplest thing that works reliably: add Basic Auth via the server, but test it. Let me just use the `.onRequest` approach which in Bun/Elysia should work.
Let me look at how Elysia handles this:
In Elysia 1.x, the `onRequest` hook is called at the very beginning. If I return a Response from it, it will be used as the response.
Actually, I think the right approach in Elysia is more nuanced. Let me just test what works.
Looking at the Elysia source code patterns, I think I should use:
```typescript
app.onBeforeHandle(({ request, set }) => {
// check auth
})
```
Or use the guard pattern:
```typescript
app.guard({
async beforeHandle({ request, set }) {
if (PASSWORD) {
// check auth
}
}
})
```
Let me just add the auth check inside the routes directly. Actually, let me just move the import and add auth. I'll use the onBeforeHandle approach.
Actually, you know what, let me try the most likely working approach. In Elysia, `onRequest` is a hook. The hooks can return a value that becomes the response. But it needs to be an `onBeforeHandle` or similar.
Let me just go with a pragmatic approach. I'll modify the code to add a `beforeHandle` in a `guard`:
```typescript
new Elysia({ websocket: { idleTimeout: 30 } })
.guard({
async beforeHandle({ request, set }) {
if (!PASSWORD) return;
const auth = request.headers.get('authorization');
if (auth && auth.startsWith('Basic ')) {
const decoded = Buffer.from(auth.slice(6), 'base64').toString();
const [, password] = decoded.split(':');
if (password =[REDACTED] PASSWORD) return;
}
set.status = 401;
set.headers['WWW-Authenticate'] = 'Basic realm="Ghostty Web Terminal"';
return 'Unauthorized';
}
})
// ... routes
```
In Elysia, `guard` with `beforeHandle` should apply to all children routes including WebSocket. When `beforeHandle` returns a string, Elysia treats it as the response body.
Actually wait - in Elysia, the `beforeHandle` in a `guard` context returns `void | Response`. If it returns something (truthy), that value is used as the response and the route handler is not called. If it returns undefined/null, processing continues.
So returning a string like `'Unauthorized'` should work as a response body.
Let me also handle the WebSocket upgrade - for WebSocket, the `beforeHandle` should prevent the upgrade if auth fails. In Elysia, the guard should handle this correctly since the WS upgrade goes through the same lifecycle.
OK let me just make the edit.Now let me install dependencies and build the server. Let me also check what the latest version of Bun is and if there might be compatibility issues. Wait, I should use `atob` instead of `Buffer` since this is Bun (which has Web API support). Actually, Bun does have `Buffer` too. Let me use `Buffer` since it's standard in Bun environment. Actually both work. Let me keep it as is. Now let me install deps and build.
Good, dependencies installed. Now let me build the server.
Built successfully. The binary is at `/opt/ghostty-web-server/dist/ghostty-web-server-linux-x64`. Let me verify it exists and create the systemd service. Now let me: 1. Create the systemd service file 2. Set up nginx as a reverse proxy 3. Start everything
Let me create the systemd service file and the nginx config. I should also check if there's already an nginx config for this domain.
Now let me check if there's an existing site config for terminal.gulasch.site or similar, and also check if there's an SSL certificate.
No existing config for gulasch.site. Let me create everything now: 1. Systemd service for ghostty-web-server 2. Nginx config for terminal.gulasch.site with SSL (using the same cert approach as the server we're on) Let me first check if we have an SSL certificate already for the domain.
No certbot installed. Let me install it and get a cert for terminal.gulasch.site. Or maybe I should first create the nginx config, then get the cert. Actually, let me first check if we have a wildcard cert or something for the server's own domain. Let me check what domains the server already serves.
OK, no SSL certs for the domain yet. Let me create the systemd service, nginx config, and get SSL. I'll use certbot for SSL. Let me install certbot and get a cert. But first, I need to make sure the domain resolves to this server. Let me create all the configs. Plan: 1. Create systemd service for ghostty-web-server 2. Create nginx config for terminal.gulasch.site with Let's Encrypt SSL 3. Install certbot and get certificate 4. Start everything Let me do it.
Good. Now let me create all the configs.
Now let me enable the nginx site and start the services. But first, let me get the SSL certificate.
Now let me start the ghostty-web-server service and get the SSL cert. For certbot, I need to do the HTTP-01 challenge, which requires port 80 to be accessible. Let me first stop nginx (since it's not running as a daemon properly yet) and then try certbot. Actually, let me just start the ghostty-web-server first, then get the cert.
Ghostty-web-server is running. Now let me get the SSL certificate using certbot. I'll need to start nginx first, then run certbot. Actually, I should get the cert using standalone mode or using nginx. Let me use certbot's nginx plugin.
The nginx start failed because the SSL certificate doesn't exist yet. Let me update the nginx config to have the SSL section commented out temporarily, get the cert, then re-add SSL. Or use certbot standalone mode. Let me use certbot standalone mode for initial cert issuance.
Port 80 is in use. It might be the nginx process that's listening even though it failed to start as a service. Let me stop whatever is on port 80 and try again. Actually, the ghostty-web-server is on port 8080. Something else is on port 80. Let me check.
Caddy is already serving on port 80. That's the existing web server for this host. I need to check if caddy is being used for the main site and if I can add the terminal.gulasch.site to caddy's config instead of using nginx. Or I can use caddy to reverse proxy the ghostty-web-server since it already handles SSL automatically. Let me check the caddy config.
Caddy is already running and handling SSL for `*.gulasch.site`. I just need to add `terminal.gulasch.site` to the caddy config, reverse proxying to `127.0.0.1:8080`. This is much simpler - I don't even need nginx since caddy handles SSL automatically. Let me revert the nginx config (or just disable it) and add the site to caddy's config instead.
I'll add terminal.gulasch.site to the caddy config, and disable/disconnect the nginx config. The ghostty-web-server is already running with auth on port 8080. Let me add the caddy config and reload caddy, and remove the nginx config.
Now let me reload caddy to pick up the new config.
Let me verify the setup is working properly by checking the ghostty-web-server responds correctly with auth.
Everything is working: 1. Without auth: returns 401 Unauthorized 2. With auth: returns the HTML page 3. Service is running and enabled Let me now verify that it works through caddy as well, by checking if caddy picked up the config.
308 is a redirect from HTTP to HTTPS (caddy's automatic HTTPS redirect). That's correct. Let me test with HTTPS.
Everything is working perfectly. Let me clean up and remove the nginx config completely.
