Particle for Angular by Entake

This package offers a small selection of reusable components that are meant to replace usage of other Angular component libraries, like Angular Material and PrimeNG. If you're looking for a themeable alternative that gives you unprecedented control of your Angular components, give Particle a try! If you're interested in contributing or find any bugs, feel free to catch us on GitHub.

ParticleColorPickerModule

ColorPickerComponent

The color picker component is a simple way to choose/input a color in hexadecimal format. It offers a text input that allows for free entry in hexadecimal format along with a color picker for supported browsers. If the browser does not support the HTML5 color picker, it is replaced with a simple color swatch that acts as a preview of the contents of the text input.

Usage

The color picker accepts a hexadecimal color string (either in short or full form, leading # optional, case is ignored) through either its value input or through one/two-way data-binding via ngModel. To read in the value of the color picker, you can listen for its ngModelChange event (if using ngModel) or its colorSelected event. The value emitted from the component is a full hexadecimal color string (ex: #0a50d3). Model updates on every color picker input, every valid text input entry and when the contents of the text input are deleted by the user.

Selector: particle-color-picker

Inputs

value setter for the internal value of the component
disabled whether the component should be disabled
ariaLabel the aria label to set for the color picker/text input
classList CSS class list to apply to the text input

Outputs

input event emitted on text input, emits the current value of the component
colorSelected event emitted on color picker close or on valid hexadecimal string input from the text input, emits the selected color as a hexadecimal string

ParticleDatePickerModule

DatePickerComponent

The date picker component allows the user to enter a date via a text input (in the form of month/day/year) or through a calendar widget.

Usage

The date picker accepts a Date object through either its value input or through one/two-way data-binding via ngModel. To read in the value of the date picker, you can listen for its ngModelChange event (if using ngModel) or its dateSelected event. The value emitted from the component is a Date object representing the user's typed/selected date. Model updates on every calendar widget selection, every valid text input entry and when the contents of the text input are deleted by the user.

Selector: particle-date-picker

Inputs

value setter for the internal value of the component
disabled whether the component should be disabled
dateRange object in the form of { minDate: Date, maxDate: Date} that acts as the valid selection range for the input/calendar widget. Min date must be less than max date. If min date is not provided, the min date is set to January 1st, {currentYear - 100}. If max date is not provided, the max date is set to December 31st, {current year + 50}.
inputId the ID to assign to the text input
ariaLabel the aria label to assign to the text input
inputClassList CSS class list to apply to the text input
calendarButtonClassList CSS class list to apply to the calendar widget button

Outputs

input event emitted on text input
dateSelected event emitted on valid date input/widget date selection, emits the selected date

CalendarComponent

The calendar component displays a calendar widget with accessibility features such as arrow key navigation of calendar dates.

Usage

The calendar accepts a Date object through its value input. To read in the value of the calendar, you can listen for its selected event. The value emitted from the component is a Date object representing the user's selection.

Selector: particle-calendar

Inputs

value setter for the internal value of the component
dateRange object in the form of { minDate: Date, maxDate: Date} that acts as the valid selection range for the calendar. Min date must be less than max date. If min date is not provided, the min date is set to January 1st, {currentYear - 100}. If max date is not provided, the max date is set to December 31st, {current year + 50}.

Outputs

selected event emitted on calendar date selection, emits the selected date
closed event emitted when the user clicks outside the widget, triggers a keyup.escape event or clicks the done button. It is the parent component's responsibility to hide the calendar, the event is merely a signal that action should be taken.

ParticleDialogModule

DialogComponent

The dialog component displays dynamic content within a dialog and supports nested dialogs within that dynamic content.

Usage

The dialog component essentially wraps an ng-content block. It is the responsibility of the parent component to show/hide the dialog based on its object input and closed event. The dialog listens for keyup.escape events (if enabled) to trigger a dialog close. If you have components in the dynamic dialog content that also rely on escape events to close, those components must listen for keyups on its own focusable elements (as opposed to listening for window.keyup) and either stop immediate propagation, or those focusable elements must have the data-dialog-close-override attribute on them, or else the escape event will close both the child component and the parent dialog.

Selector: particle-dialog

Inputs

object an input of type any where that input becoming truthy will show the dialog and falsy will hide
title the title of the dialog. Note: always use the Angular input syntax ([title]="'Title'") to avoid IE11 triggering a native tooltip of the dialog title
titleClass CSS class to apply to the title section of the dialog
bodyClass CSS class to apply to the body section of the dialog
showTitle whether to show the title section of the dialog (default true)
allowClose whether to show the dialog close button and enable escape to close (default true)
height the height of dialog (can be any valid CSS measurement)
width the width of dialog (can be any valid CSS measurement)

Outputs

opened event emitted on dialog open
closed event emitted on dialog close

ParticleDropdownModule

DropdownComponent

The dropdown component acts as an enhanced HTML select. It supports both regular dropdown options (only the label being displayed) and templated options (options for which you can supply a ng-template to act as a template for each dropdown option). The dropdown is fully accessible as well, and supports all the accessibility options that a native select would (such as arrow key controls for option selection).

Usage

The dropdown accepts a string or number through either its value input or through one/two-way data-binding via ngModel. To read in the value of the dropdown, you can listen for its ngModelChange event (if using ngModel) or its change event. The value emitted from the component is a string or number representing the value of the user's selected option. Model updates on every option change, whether it be triggered by clicking on an option or using arrow key controls.

Using Dropdown Options

The dropdown supports both flat options or option groups, and the options for a single dropdown can be a mix of the two. A dropdown option has a value (string or number), a label, disabled indicator, and an optional data context object (the data context object is not needed if you're not planning to use templating). Whether data context is passed in or not for an option, each option internally will have a data context object which will minimally contain the option's label (inserted into the $implicit property if not already taken, or the label property if $implicit is already present in the object). Dropdown option groups contain a group label, and an array of dropdown options.

Using Dropdown Option Templating

Dropdown option templating relies on Angular's ng-template syntax. To provide an option template to the dropdown, you simply define a ng-template as the content of the dropdown. If you do not wish to use templating, pass nothing into the content between the dropdown tags. To display data from an option's data context within the option template, you use Angular's ng-template let-var syntax. This allows you to define variables within the option template that will then be filled by the corresponding property in an option's data context. As mentioned in the previous section, the option's label is automatically added to each option's data context, so to display the label in the template, you can just define a variable without a value, and it will be filled by the $implicit entry. Here's an example of how a typical use case of the dropdown with templating would look:

  <particle-dropdown [options]="[
                    { value: 'red', label: 'Red', dataContext: { 'colorClass': 'bg_red' } },
                    { value: 'green', label: 'Green', disabled: true, dataContext: { 'colorClass': 'bg_green' } },
                    { value: 'blue', label: 'Blue', dataContext: { 'colorClass': 'bg_blue' } },
                    { groupLabel: 'Purple Values', options: [
                        { value: 'darkPurple', label: 'Dark Purple', dataContext: { 'colorClass': 'bg_purple_dark_4' } },
                        { value: 'purple', label: 'Purple', dataContext: { 'colorClass': 'bg_purple' } },
                        { value: 'lightPurple', label: 'Light Purple', dataContext: { 'colorClass': 'bg_purple_light_4' } }
                    ]}
                 ]">
    <ng-template let-colorClass="colorClass" let-label>
      <div class="circle_14px mar_right5"
           [ngClass]="colorClass">
      </div> {{label}}
    </ng-template>
  </particle-dropdown>

Notice how, in the ng-template, the variable definition value (in quotes) for colorClass matches up with the property of the same name in the data context objects for each option. Also notice how the variable definition for label has no value assigned, that's because the dropdown component will automatically put an option's label into the $implicit property, which Angular uses to fill in the value for any referenced variables that do not have a specified value. You can of course choose to explicitly add the label to the option's data context and use that value in the label variable assignment as well.

Selector: particle-dropdown

Inputs

value string or number representing the value of the selected option
options array of DropdownOption | DropdownOptionGroup acting as the options to populate the dropdown
disabled whether the dropdown should be disabled or not
placeholder placeholder text to show in the dropdown when no option is selected
ariaLabel aria label to assign to the dropdown
classList CSS class list to apply to the dropdown

Outputs

change: event emitted on dropdown option selection if selection has changed from the previous value, emits the selected value

ParticleEndpointStateModule

EndpointStateComponent

The endpoint state component serves as a catch-all for displaying endpoint states (loading, not found and error).

Usage

The endpoint state component is split into four different possible states: loading, loadingOverlay, empty and error. You specify which state the component should be in by passing in true to the desired state as an input. Note: only one state should be active at a time.

Inputs

loading whether the component should be in the loading state
loadingIcon an icon class to display in the loading state
loadingText main text to display in the loading state
loadingSubtext subtext to display in the loading state
loadingOverlay whether the component should be in the loading overlay state (whole-screen overlay)

ParticleIconsModule

IconSelectComponent

The icon select component allows a user to search for and select either a Fontawesome or Particle (custom) icon.

Usage

The icon select accepts an icon class through either its value input or through one/two-way data-binding via ngModel. To read in the value of the icon select, you can listen for its ngModelChange event (if using ngModel) or its selected event. The value emitted from the component is the selected icon class. Model updates on confirm button click.

Inputs

value setter for the internal value of the component
disabled whether the component is disabled
buttonColorClass CSS class to apply to the icon dialog show button
buttonSizing the size (width/height) of the icon dialog show button in pixels

Outputs

opened event emitted on icon dialog open

allowSpaces whether to allow spaces in input (default false)

ParticleMultiSelectModule

MultiSelectComponent

The multi-select component acts as an enhanced HTML select that allows multiple selections. It supports both regular multi-select options (only the label being displayed) and templated options (options for which you can supply a ng-template to act as a template for each multi-select option). The multi-select is fully accessible as well, and supports all the accessibility options that a multi-select should (such as arrow key controls for option selection).

Usage

The multi-select accepts an array of strings or numbers through either its value input or through one/two-way data-binding via ngModel. To read in the value of the multi-select, you can listen for its ngModelChange event (if using ngModel) or its change event. The value emitted from the component is an array of strings or numbers representing the values of the user's selected options. Model updates on every option select/de-select, whether it be triggered by clicking on an option or using arrow key controls.

Using Dropdown Options

The multi-select supports both flat options or option groups, and the options for a single multi-select can be a mix of the two. A multi-select option has a value (string or number), a label, disabled indicator, and an optional data context object (the data context object is not needed if you're not planning to use templating). Whether data context is passed in or not for an option, each option internally will have a data context object which will minimally contain the option's label (inserted into the $implicit property if not already taken, or the label property if $implicit is already present in the object). Multi-select option groups contain a group label, and an array of multi-select options.

Using Dropdown Option Templating

Multi-select option templating relies on Angular's ng-template syntax. To provide an option template to the multi-select, you simply define a ng-template as the content of the multi-select. If you do not wish to use templating, pass nothing into the content between the multi-select tags. To display data from an option's data context within the option template, you use Angular's ng-template let-var syntax. This allows you to define variables within the option template that will then be filled by the corresponding property in an option's data context.

Here's an example of how a typical use case of the multi-select with templating would look:

  <particle-multi-select [options]="[
                    { value: 'red', label: 'Red', dataContext: { 'colorClass': 'bg_red' } },
                    { value: 'green', label: 'Green', disabled: true, dataContext: { 'colorClass': 'bg_green' } },
                    { value: 'blue', label: 'Blue', dataContext: { 'colorClass': 'bg_blue' } },
                    { groupLabel: 'Purple Values', options: [
                        { value: 'darkPurple', label: 'Dark Purple', dataContext: { 'colorClass': 'bg_purple_dark_4' } },
                        { value: 'purple', label: 'Purple', dataContext: { 'colorClass': 'bg_purple' } },
                        { value: 'lightPurple', label: 'Light Purple', dataContext: { 'colorClass': 'bg_purple_light_4' } }
                    ]}
                 ]">
    <ng-template let-colorClass="colorClass" let-label>
      <div class="circle_14px mar_right5"
           [ngClass]="colorClass">
      </div> {{label}}
    </ng-template>
  </particle-multi-select>

ParticleNotificationModule

Notifications

A notification is a simple way to provide feedback to a user in respect to some action (successful resource save, some error occurred, etc). Notifications have an ID (system generated), severity ('success' | 'info' | 'warn' | 'error'), summary and detail message (optional).

NotificationComponent

The notification component allows for the display of notifications in an application.

Usage

The notification component should be dropped into the app root so that the display of notifications is available throughout the entire application. Once the component has been placed, no further action is needed. It's up to other components/services to add notifications for display in the notification component.

NotificationService

The notification service is a root Injectable that allows components/services throughout an application to add notifications to the notification pool for display.

Usage

The notification service can be injected into components/services to add a notification through its add method, which accepts a notification object, adds it and then removes it after the configured notification life has passed. Notification life (the time before a notification is automatically removed from the view) can also be configured via the service's setNotificationLife method.

Methods

add accepts a notification object and adds it to the current notifications array
deleteNotification accepts a notification ID and deletes the corresponding notification (if it exists)
getNotifications get an array of the current notifications as an RxJS Observable
setNotificationLife set the notification life for new notifications
