+# Installation Guide - Ubuntu
+
+Panduan instalasi `doclink_web` di Ubuntu dengan Apache reverse proxy untuk URL publik seperti:
+
+```text
+https://domain.com/docklink-desktop
+```
+
+## Prerequisites
+
+- Ubuntu Server
+- Node.js 18+ atau yang kompatibel
+- Apache2
+- SSL certificate jika ingin HTTPS
+
+## 1. Copy Project
+
+Masuk ke folder project:
+
+```bash
+cd /path/to/doclink_web
+```
+
+Pastikan file berikut ada:
+
+- `server.js`
+- `styles.css`
+- `logo.png`
+- `start.sh`
+- `stop.sh`
+
+## 2. Jalankan App
+
+Set base path sesuai URL publik:
+
+```bash
+export DOCLINK_BASE_PATH=/docklink-desktop
+export PORT=5173
+node server.js
+```
+
+Kalau mau jalan di background, pakai script:
+
+```bash
+DOCLINK_BASE_PATH=/docklink-desktop PORT=5173 ./start.sh
+```
+
+### Catatan
+
+- `DOCLINK_BASE_PATH` harus sama dengan path publik di browser.
+- Nama folder project di disk tidak harus sama.
+- Aplikasi tetap bisa diakses lewat port lokal `5173`, lalu Apache yang meneruskan request ke sana.
+
+## 3. Install Dependencies Ubuntu
+
+Update paket dan install Apache:
+
+```bash
+sudo apt update
+sudo apt install -y apache2
+```
+
+Kalau Node.js belum ada, install sesuai versi yang kamu pakai di server.
+
+## 4. Aktifkan Module Apache
+
+Di Ubuntu / Debian:
+
+```bash
+sudo a2enmod proxy proxy_http ssl
+sudo systemctl restart apache2
+```
+
+## 5. Buat Virtual Host
+
+Edit konfigurasi Apache di Ubuntu:
+
+```bash
+sudo nano /etc/apache2/sites-available/domain.conf
+```
+
+Contoh konfigurasi:
+
+```apache
+<VirtualHost *:80>
+    ServerName domain.com
+    Redirect permanent / https://domain.com/
+</VirtualHost>
+
+<VirtualHost *:443>
+    ServerName domain.com
+
+    SSLEngine on
+    SSLCertificateFile /path/to/fullchain.pem
+    SSLCertificateKeyFile /path/to/privkey.pem
+
+    ProxyPreserveHost On
+    ProxyRequests Off
+
+    RedirectMatch 301 ^/docklink-desktop$ /docklink-desktop/
+
+    ProxyPass        /docklink-desktop/  http://127.0.0.1:5173/
+    ProxyPassReverse /docklink-desktop/  http://127.0.0.1:5173/
+</VirtualHost>
+```
+
+## 6. Enable Site
+
+Aktifkan site dan reload Apache:
+
+```bash
+sudo a2ensite domain.conf
+sudo systemctl reload apache2
+```
+
+## 7. Test
+
+Buka URL berikut:
+
+```text
+https://domain.com/docklink-desktop/
+```
+
+Kalau benar, aplikasi akan tampil tanpa expose port `5173` ke publik.
+
+## 8. Stop App
+
+Kalau pakai `start.sh`:
+
+```bash
+./stop.sh
+```
+
+Kalau mau stop port tertentu:
+
+```bash
+./stop.sh 5173
+```
+
+## Troubleshooting
+
+### Halaman tidak muncul
+
+- Pastikan Node.js app masih jalan di `127.0.0.1:5173`
+- Pastikan Apache module `proxy` dan `proxy_http` aktif
+- Pastikan `DOCLINK_BASE_PATH=/docklink-desktop`
+
+## Ubuntu Notes
+
+- File konfigurasi Apache biasanya ada di:
+  - `/etc/apache2/sites-available/`
+  - `/etc/apache2/sites-enabled/`
+- Log Apache biasanya ada di:
+  - `/var/log/apache2/access.log`
+  - `/var/log/apache2/error.log`
+- Service Apache dikelola dengan:
+  ```bash
+  sudo systemctl status apache2
+  sudo systemctl restart apache2
+  sudo systemctl reload apache2
+  ```
+
+### CSS atau logo tidak loading
+
+- Cek apakah request asset ikut lewat path `/docklink-desktop/...`
+- Pastikan Apache proxy tidak memotong base path secara salah
+
+### Redirect balik ke root
+
+- Pastikan semua request ke app memakai base path yang sama
+- Gunakan `DOCLINK_BASE_PATH=/docklink-desktop`

+# DocLink Web Installation Guide for Ubuntu
+
+This guide explains how to run `doclink_web` on Ubuntu behind Apache, using a subfolder URL such as:
+
+```text
+https://domain.com/docklink-desktop
+```
+
+## 1. Requirements
+
+- Ubuntu Server
+- Apache 2
+- Node.js 18+ or compatible
+- A valid SSL certificate if you want HTTPS
+
+## 2. Copy the Application
+
+Place the project on the server and enter the project directory:
+
+```bash
+cd /path/to/doclink_web
+```
+
+Make sure these files exist:
+
+- `server.js`
+- `styles.css`
+- `logo.png`
+- `start.sh`
+- `stop.sh`
+
+## 3. Install Apache on Ubuntu
+
+Update package lists and install Apache:
+
+```bash
+sudo apt update
+sudo apt install -y apache2
+```
+
+If Node.js is not installed yet, install the version you want to use on the server.
+
+## 4. Create the systemd Service
+
+The app should run as a service so it starts automatically and keeps running in the background.
+
+Create an environment file, for example:
+
+```bash
+sudo nano /etc/doclink-web.env
+```
+
+Example content:
+
+```bash
+DOCLINK_BASE_PATH=/docklink-desktop
+PORT=5173
+DOCLINK_API_BASE=https://devbandungraya.aplikasi.web.id/one-api-doctor/doctor_mitra
+```
+
+Then create the service file:
+
+```bash
+sudo nano /etc/systemd/system/doclink-web.service
+```
+
+Example content:
+
+```ini
+[Unit]
+Description=DocLink Web
+After=network.target
+
+[Service]
+Type=simple
+WorkingDirectory=/path/to/doclink_web
+EnvironmentFile=/etc/doclink-web.env
+ExecStart=/usr/bin/node /path/to/doclink_web/server.js
+Restart=on-failure
+RestartSec=3
+User=www-data
+Group=www-data
+
+[Install]
+WantedBy=multi-user.target
+```
+
+Reload systemd and enable the service:
+
+```bash
+sudo systemctl daemon-reload
+sudo systemctl enable doclink-web
+sudo systemctl start doclink-web
+```
+
+Check status:
+
+```bash
+sudo systemctl status doclink-web
+```
+
+## 5. Run the Application Manually
+
+This step is optional. Use it only if you want to test the app without systemd.
+
+Run it directly:
+
+```bash
+export DOCLINK_BASE_PATH=/docklink-desktop
+export PORT=5173
+node server.js
+```
+
+If you prefer the helper script:
+
+```bash
+DOCLINK_BASE_PATH=/docklink-desktop PORT=5173 ./start.sh
+```
+
+Important notes:
+
+- `DOCLINK_BASE_PATH` must match the public URL path.
+- The local project folder name can be anything.
+- Apache will forward requests to the Node.js app on `127.0.0.1:5173`.
+
+## 6. Enable Apache Modules
+
+Enable the required proxy and SSL modules:
+
+```bash
+sudo a2enmod proxy proxy_http ssl
+sudo systemctl restart apache2
+```
+
+## 7. Configure Apache Virtual Host
+
+Create or edit your site config in:
+
+```bash
+sudo nano /etc/apache2/sites-available/domain.conf
+```
+
+Example configuration:
+
+```apache
+<VirtualHost *:80>
+    ServerName domain.com
+    Redirect permanent / https://domain.com/
+</VirtualHost>
+
+<VirtualHost *:443>
+    ServerName domain.com
+
+    SSLEngine on
+    SSLCertificateFile /path/to/fullchain.pem
+    SSLCertificateKeyFile /path/to/privkey.pem
+
+    ProxyPreserveHost On
+    ProxyRequests Off
+
+    RedirectMatch 301 ^/docklink-desktop$ /docklink-desktop/
+
+    ProxyPass        /docklink-desktop/  http://127.0.0.1:5173/
+    ProxyPassReverse /docklink-desktop/  http://127.0.0.1:5173/
+</VirtualHost>
+```
+
+If you want a reusable deployment template, start from:
+
+- `deploy/apache-vhost.template.conf`
+- `deploy/env.template`
+
+Then replace:
+
+- `__SERVER_NAME__`
+- `__BASE_PATH__`
+- `__APP_PORT__`
+- `__SSL_CERT_FILE__`
+- `__SSL_KEY_FILE__`
+
+## 8. Enable the Site
+
+Enable the site and reload Apache:
+
+```bash
+sudo a2ensite domain.conf
+sudo systemctl reload apache2
+```
+
+## 9. Verify the Deployment
+
+Open the application in the browser:
+
+```text
+https://domain.com/docklink-desktop/
+```
+
+If everything is configured correctly, the application should load without exposing port `5173` publicly.
+
+## 10. Stop the Application
+
+If you started the app with the helper script:
+
+```bash
+./stop.sh
+```
+
+Or stop a specific port:
+
+```bash
+./stop.sh 5173
+```
+
+## 11. Ubuntu-Specific Locations
+
+- Apache site configs:
+  - `/etc/apache2/sites-available/`
+  - `/etc/apache2/sites-enabled/`
+- Apache logs:
+  - `/var/log/apache2/access.log`
+  - `/var/log/apache2/error.log`
+- Apache service commands:
+  ```bash
+  sudo systemctl status apache2
+  sudo systemctl restart apache2
+  sudo systemctl reload apache2
+  ```
+
+## 12. Troubleshooting
+
+### The page does not open
+
+- Check that the `doclink-web` service is running
+- Check that the Node.js app is listening on `127.0.0.1:5173`
+- Check that Apache modules `proxy` and `proxy_http` are enabled
+- Confirm that `DOCLINK_BASE_PATH=/docklink-desktop`
+
+### CSS or logo does not load
+
+- Confirm requests are going through `/docklink-desktop/...`
+- Check the Apache proxy configuration for the correct trailing slash
+
+### Redirects go back to `/`
+
+- Make sure every public request uses the same base path
+- Keep `DOCLINK_BASE_PATH` aligned with the URL folder

 - Order search, order detail helpers, FPP loading, password change, and special message save are wired through the API adapter with mock fallback for local preview.
 - `start.sh` writes a pid file named `.doclink-web.pid` and a log file named `doclink-web.log`.
