fluent-cards 0.1.0b14

Fluent builder API for Adaptive Cards

FluentCards — Python

A Python library for building Adaptive Cards using a fluent builder pattern with strong typing and built-in schema validation.

Also available for .NET (NuGet), Node.js (npm), and Go.

Installation

pip install fluent-cards

Quick Start

from fluent_cards import AdaptiveCardBuilder, TextSize, TextWeight, to_json

card = (AdaptiveCardBuilder.create()
    .with_version('1.5')
    .add_text_block(lambda tb: tb
        .with_text('Hello, FluentCards!')
        .with_size(TextSize.Large)
        .with_weight(TextWeight.Bolder)
        .with_wrap(True))
    .build())

print(to_json(card))

Output:

{
  "type": "AdaptiveCard",
  "version": "1.5",
  "body": [
    {
      "type": "TextBlock",
      "text": "Hello, FluentCards!",
      "size": "Large",
      "weight": "Bolder",
      "wrap": true
    }
  ]
}

Features

• Fluent builder API — chainable, readable card construction
• Strong typing — enums for all Adaptive Cards schema values (TextSize, TextWeight, Colors, ContainerStyle, etc.)
• Built-in validation — catches schema errors before the card is sent
• Zero dependencies — pure Python, no third-party packages required
• Full schema support — TextBlock, Image, ColumnSet, Container, FactSet, ActionSet, and more

More Examples

Card with image and actions

from fluent_cards import AdaptiveCardBuilder, TextSize, TextWeight, ActionStyle

card = (AdaptiveCardBuilder.create()
    .with_version('1.5')
    .add_text_block(lambda tb: tb
        .with_text('Order Confirmed')
        .with_size(TextSize.Large)
        .with_weight(TextWeight.Bolder))
    .add_text_block(lambda tb: tb
        .with_text('Your order #12345 has been placed.')
        .with_wrap(True))
    .add_action(lambda a: a
        .open_url('https://example.com/track/12345')
        .with_title('Track Order'))
    .build())

Card with columns

from fluent_cards import AdaptiveCardBuilder

card = (AdaptiveCardBuilder.create()
    .with_version('1.5')
    .add_column_set(lambda cs: cs
        .add_column(lambda col: col
            .with_width('auto')
            .add_text_block(lambda tb: tb.with_text('Name:')))
        .add_column(lambda col: col
            .with_width('stretch')
            .add_text_block(lambda tb: tb.with_text('Jane Doe'))))
    .build())

Using choices (Input.ChoiceSet)

from fluent_cards import AdaptiveCardBuilder

card = (AdaptiveCardBuilder.create()
    .with_version('1.5')
    .add_input_choice_set(lambda cs: cs
        .with_id('priority')
        .with_label('Priority')
        .add_choice('High', 'high')
        .add_choice('Medium', 'medium')
        .add_choice('Low', 'low'))
    .build())

Validation

from fluent_cards import AdaptiveCardBuilder, validate

card = AdaptiveCardBuilder.create().build()  # no version set
errors = validate(card)

for error in errors:
    print(error)
