node-red-contrib-docxtemplater

node-red-contrib-docxtemplater is a Node-RED node that enables you to generate Word documents (.docx) by dynamically filling templates using Docxtemplater. With this node, you can create rich, personalized Word documents directly from Node-RED, making it ideal for report generation, invoices, and custom documents.

Installation

To install, run the following command in your Node-RED directory:

npm install omerkaptan/node-red-contrib-docxtemplater

Usage

1. Template Creation: Start by creating a .docx template with placeholders formatted as tags, like {{name}}, {{date}}, or {{items}}. Tags are placeholders that Docxtemplater will replace with actual values.
2. Template Input: Provide the .docx template to the node, either as a file path or binary input.
3. Data Input: Send data as a JSON object, mapping each tag to a value (e.g., { "name": "Alice", "date": "2024-10-30" }).
4. Output: The node outputs a .docx document where each placeholder is replaced by the data you've provided.

Examples

Here are some specific tag usage examples you can use with your .docx templates:

• Simple Text Replacement: Replace {{name}} with a name:

  { "name": "Alice" }

• Looping Over Arrays: To add a list of items in a table format, use the {{#items}}...{{/items}} tag structure in your .docx template, and pass an array of objects as shown below:

  {
    "items": [
      { "description": "Item 1", "price": 10 },
      { "description": "Item 2", "price": 15 }
    ]
  }

• Conditional Tags: Use conditional tags to show or hide content based on a value:

  { "isApproved": true }

  In your template, use tags like {{#isApproved}}Approved{{/isApproved}} to display "Approved" only if isApproved is true.

For more advanced tag types and formatting options, see the full Docxtemplater Tag Types documentation.

Example Flow

1. Template Node: Use a file input node to load the .docx template.
2. Data Node: Add a JSON node with the structured data to fill in placeholders.
3. Docxtemplater Node: Connect the template and data nodes to the docxtemplater node.
4. Output Node: Use a file output node to save the generated .docx document.

Dependencies

This node depends on Docxtemplater for template processing, so refer to their documentation for further customization options.
