+# docxtemplater-server
+
+A lightweight HTTP service for processing DOCX templates with JSON data.
+
+## What It Does
+
+This service accepts a DOCX template file and JSON data via HTTP POST, processes the template using [docxtemplater](https://docxtemplater.com/), and returns the generated document.
+
+## API
+
+### `POST /process-template`
+
+Process a DOCX template with provided data.
+
+**Request Format:**
+- Content-Type: `multipart/form-data`
+- Fields:
+  - `template` (file): The DOCX template file
+  - `data` (text): JSON string containing template variables
+
+**Example using cURL:**
+```bash
+curl -X POST http://localhost:3000/process-template \
+  -F "template=@template.docx" \
+  -F 'data={"name":"John Doe","date":"2026-03-21"}'
+```
+
+**Response:**
+- Content-Type: `application/vnd.openxmlformats-officedocument.wordprocessingml.document`
+- Body: Generated DOCX file (binary)
+
+**Error Responses:**
+- `400 Bad Request`: Missing template or data
+- `500 Internal Server Error`: Processing error
+
+## Running Locally
+
+### With Docker Compose (recommended)
+```bash
+docker-compose up
+```
+
+The service will be available at `http://localhost:3000`.
+
+### With Node.js
+```bash
+npm install
+npm start
+```
+
+## Environment Variables
+
+- `PORT` — Server port (default: `3000`)
+
+## Template Syntax
+
+Templates use docxtemplater syntax with curly braces:
+
+```
+Hello {name}, today is {date}.
+```
+
+Supports:
+- Simple variables: `{variable}`
+- Loops: `{#items}{name}{/items}`
+- Conditionals: `{#isActive}Active{/isActive}`
+
+See [docxtemplater documentation](https://docxtemplater.com/docs/tag-types/) for full syntax.
