Pastanaga Angular

Pastanaga Angular is an Angular implementation of Pastanaga design system offering a set of re-usable UI components which are covering typical needs of any web application. It is maintained by Plone and Guillotina communities. It aims to remain simple, and pays particular attention to:

• Accessibility: semantic is respected, and aria attributes are implemented where needed;
• Internationalisation: the translation service allows to manage several languages in a single Angular build, and support granular overriding;
• Maintenance: releases are frequent, and upgrade to latest Angular version is performed very quickly after each Angular release.

See https://plone.github.io/pastanaga-angular for usage examples and developer guide.

Setup

Installation

You can install Pastanaga-angular using its npm package:

• using npm:

npm install @guillotinaweb/pastanaga-angular

• using yarn:

yarn add @guillotinaweb/pastanaga-angular

But if you want to build your own demo application using pastanaga demo components, you need to install it using mrs-developer:

• first install mrs-developer if you don't already have it:

yarn add mrs-developer 

• then add pastanaga-angular to your mrs.developer.json configuration (you can choose a specific tag as below, or a branch):

{
  "pastanaga-angular": {
    "url": "[e-mail]:plone/pastanaga-angular.git",
    "https": "https://github.com/plone/pastanaga-angular.git",
    "path": "/projects/pastanaga-angular/src",
    "package": "@guillotinaweb/pastanaga-angular",
    "tag": "2.52.1"
  }
}

• and launch the installation by running missdev:

missdev

Note: By default, missdev will install the dependencies in src/dev folder. If you're in a workspace with a mono-repository structure (using nx for instance), then you probably want to install pastanaga-angular in your libs folder. You can do so by using missdev --output option:

missdev --output=../libs

Configuration

Style preprocessing

Pastanaga-angular requires two files (pastanaga-core-overrides.scss and pastanaga-component-overrides.scss) to be in the src folder of any project using it. In order for those files to be found during the compilation, you have to add src folder in style preprocessing options of angular.json:

    "stylePreprocessorOptions": {
        "includePaths": [
            "src"
        ]
    }

Assets

Pastanaga-angular is using Poppins fonts and Quanta glyphs.

If you want to use the same fonts and glyphs sprite, declare Pastanaga assets in angular.json:

• when using npm package:

{
  "assets": [
    "src/favicon.ico",
    "src/assets",
    {
      "glob": "**/*",
      "input": "./node_modules/@guillotinaweb/pastanaga-angular/assets",
      "output": "assets"
    }
  ]
}

• when using mrs-developer:

{
  "assets": [
    "src/favicon.ico",
    "src/assets",
    {
      "glob": "**/*",
      "input": "./src/develop/pastanaga-angular/projects/pastanaga-angular/assets",
      "output": "assets"
    }
  ]
}

Core style

Import Pastanaga core style in your application style (usually src/styles.scss):

• when using npm package:

@import "~@guillotinaweb/pastanaga-angular/lib/styles/core";

• when using mrs-developer

@import "./develop/pastanaga-angular/projects/pastanaga-angular/lib/styles/core";

Theming

Fonts

If you want to use Pastanaga fonts in your application, you need to

• declare the $font-path in your application style:

$font-path: '../../../assets/fonts';

Warning: since angular 10, scss variable is now relative to the place it is called.

• and import Pastanaga fonts in your application style as well:
  • when using npm package

@import "~@guillotinaweb/pastanaga-angular/lib/styles/fonts";

• when using mrs-developer

@import "./develop/pastanaga-angular/projects/pastanaga-angular/lib/styles/fonts";

Overriding theme

Any project using pastanaga-angular must have two files (pastanaga-core-overrides.scss and pastanaga-component-overrides.scss) in their src folder. Keep those file empty if you want to use Pastanaga theme.

If you have your own theme, you can override pastanaga theme by overriding the tokens in these two files:

• pastanaga-core-overrides.scss allows to override variables from:
  • theme/palette
  • theme/layout
  • theme/scrollbar
  • theme/shadows
  • theme/spacing
  • theme/transitions
  • theme/typography
  • theme/z-index
• pastanaga-component-overrides.scss allows to override variables from all other theming files like:
  • theme/avatar
  • theme/body
  • theme/button
  • theme/chips
  • theme/icon
  • theme/menu
  • theme/modal
  • theme/tables
  • theme/tabs
  • theme/textfield
  • theme/toast
  • theme/toggle
  • theme/tooltip

Pastanaga theme is defined in src/lib/styles/theme folder. Any variable with !default suffix can be overwritten.

Pastanaga theme is built around token. For example, _palette.token.scss contains all the colors used in Pastanaga with general token names (e.g. $color-neutral-regular, $color-primary-stronger). See the full list in https://plone.github.io/pastanaga-angular/palette.

Then, some components have a second layer of tokens. For example buttons have a list of tokens for each aspect and kind (e.g. $color-text-button-primary-solid, $color-background-button-primary-solid,…). So you can have your own theme by overwriting the whole color palette or just by changing some aspects of some components.

Module names

In Pastanaga 2+, we prefix all modules with Pa: ButtonModule becomes PaButtonModule.

Components common properties

Pastanaga now contains some useful types for properties configuring several components:

• Kind: primary | secondary | destructive | inverted
• Size: tee-shirt size going from small to xxlarge. Not all sizes are available for all components

Buttons

We changed the way to configure buttons:

• color is now managed by kind property
• size is now expecting to be one of the values of Size type
• border property is replaced by aspect which can be solid or basic

See https://plone.github.io/pastanaga-angular/button for full documentation.

Icons

pa-icon is now using a svg sprites to display icons by name. You can still provide a full path to display any other image though.

See https://plone.github.io/pastanaga-angular/icon for full documentation.

Form elements

We changed form elements hierarchy: now they are all in the same place under controls folder. They still belong to two distinct modules (PaTextFieldModule and PaTogglesModule).

All controls are sharing some properties:

• PaFormControlDirective is the base class containing common properties (like id, name, disabled…) for all form elements components
• NativeTextFieldDirective is extending PaFormControlDirective and contains common properties for all text field elements (like placeholder, value, readonly,…)
