Custom Properties

Custom Properties are additional metadata for notes, such as the author or the date it was published. You can add custom properties to your notes using Front Matter and specify properties in the Configuration file to show them in the Panel.

Examples

Author

This example shows how to add an author to a note. First, define the author in your note using Front Matter:

---
author: John Doe
---

# My Note

Then add the property to the configuration file:

// /app.json
{
  "customProperties": {
    "properties": [
      {
        "name": "author"
      }
    ]
  }
}

Published Date

This example shows how to add a date to a note. First, define the date in your note using Front Matter:

---
publishedOn: 2023-08-01
---

# My Note

Then add the property to the configuration file:

// /app.json
{
  "customProperties": {
    "properties": [
      {
        "name": "publishedOn",

        // Optionally, format the date.
        "options": {
          "date": {
            "locale": "en-US",
            "format": { "dateStyle": "full" }
          }
        }
      }
    ]
  }
}

This example shows how to add a list of related notes to a note. First, define the related notes in your note using Front Matter. Related notes can be referenced using the same wikilink syntax as in your notes.

---
related:
  - "[[My other note]]" # Must be wrapped in quotes!
  - "[[My third note]]"
---

# My Note

Then add the property to the configuration file:

// /app.json
{
  "customProperties": {
    "properties": [
      {
        "name": "related"
      }
    ]
  }
}

Wikilinks used in custom properties are not listed in the incoming / outgoing sections of the panel.

Arbitrary Properties

This example shows how to add arbitrary properties to a note. First, define the properties in your note using Front Matter. For arbitrary properties, it's recommended to use a nested object (meta in this example).

---
meta:
  language: German
  license: MIT
---

# My Note

Then add the property to the configuration file:

// /app.json
{
  "customProperties": {
    "properties": [
      {
        // Includes all props in the meta object
        "path": "meta"
      }
    ]
  }
}

Configuration API

What properties are shown in the panel can be configured in the Configuration file.

{
  "customProperties": {
    // Define a list of properties to show in the panel.
    "properties": [
      {
        // The path to the property, if your property is nested (optional).
        "path": "meta",

        // The name of the property.
        // If omitted, all properties in the path are shown.
        // Define a regular expression to match multiple properties.
        "name": "author",

        // The label to show in the panel.
        // If omitted, is inferred from the property name.
        "label": "Lovely written by",

        // Options for the property value (optional).
        "options": {
          // Options for date values
          "date": {
            "locale": "en-US",
            "format": { "dateStyle": "full" }
          },
          // Options for numeric values
          "number": {
            "locale": "en-US",
            "format": {
              "style": "currency",
              "currency": "USD",
              "currencyDisplay": "symbol"
            }
          }
        }
      }
    ]
  }
}
