react-confirm-service

Provides a service to show alerts, confirmations, and choices in react apps.

Installation

npm install react-confirm-service

Basic Usage

First you start by using the ConfirmComponentHost in your application:

import { ConfirmComponentHost } from "react-confirm-service";

...

<MyApp>
    <ConfirmComponentHost
        renderAlert={props => (
            <Notification
                isOpen={props.isVisible}
                onClose={props.onClose}
            >
                {props.message}
            </Notification>
        )}
        renderConfirm={props => (
            <Dialog
                isOpen={props.isOpen}
                title={props.title}
            >
                {/* render content, buttons, ... */}
            </Dialog>
        )}
        renderChoice={props => {
            const options = props.options.map(option => (
                <li
                    key={option.key}
                    onClick={() => props.onConfirm(option)}
                >
                    {option.key}
                </li>
            ));

            return (
                <Dialog
                    isOpen={props.isOpen}
                    title={props.title}
                >
                    <>
                        <ul>
                            {options}
                        </ul>
                        <button onClick={props.onCancel}>Cancel</button>
                    </>
                </Dialog>
            );
        }}
    />
</MyApp>

The implementation depends on the UI components you want to use to show alerts, confirmation, and choice dialogs.

After that, you can use the ConfirmService anywhere in your application:

import { ConfirmService } from "react-confirm-service";

...

ConfirmService.alert("Something happened", "info");

...

ConfirmService.confirm({
    message: "Close without saving?"
})
    .then(/* Yes */)
    .catch(/* No */);

...

ConfirmService.choose({
    title: "Fruits",
    options: [
        { key: "Bananas" },
        { key: "Apples" },
        { key: "Pineapples" },
    ]
})
    .then(choice => /* ... */)
    .catch(/* cancelled */)

How to use the ConfirmComponentHost

The ConfirmComponentHost accepts the following props:

Property	Required	Description
renderAlert	yes	Provide a function which renders the alert component. See renderAlert
renderConfirm	yes	Provide a function which renders the confirmation component. See renderConfirm
renderChoice	no	Provide a function which renders the choice component. See renderChoice
strings	no	Takes an object to provide default values for yes, no, and cancel button captions. Use this to localize these texts.
alertDurations	no	You can provide an object to set the durations of an alert for each severity in ms. The defaults are: info: 3000, success: 3000, warning: 10000, error: 10000.

You can use the ConfirmComponentHost in multiple places in your application. The ConfirmService will use the last one which was mounted.

renderAlert

renderAlert is a function with one parameter of type AlertRenderProps:

Property	Description
isVisible	Alert is shown or not.
message	The message to display to the user.
duration	How long should the message be displayed, in ms.
severity	The severity of the alert. Use different icons and/or colors.
onClose	Call this function when the alert should close.

renderConfirm

renderConfirm is a function with one parameter of type ConfirmRenderProps:

Property	Description
isOpen	Is the confirmation dialog opened?
title	The optional title of the confirmation.
message	The message of the confirmation.
confirmCaption	The caption of the button to accept the confirmation.
onConfirm	Call this function when the button to accept is pressed.
denyCaption	The caption of the button to deny the confirmation. Do not display this button if the caption is an empty string ("").
onDeny	Call this function when the button to deny is pressed.

renderChoice

renderChoice is a function with one parameter of type ChoiceRenderProps:

Property	Description
isOpen	Is the choice dialog opened?
title	The optional title of the choice.
options	The list of selectable options to show.
type	The optional type of the options to distinguish when rendering.
cancelCaption	The caption of the action to cancel the choice.
onConfirm	Call this function when a choice is selected.
onCancel	Call this function when the choice is cancelled.
extra	Optional custom data.

How to use the ConfirmService

Alert

To show an alert to the user, call the alert function. It has the following parameters:

Parameter	Required	Description
message	yes	The message to display.
severityOrOptions	yes	The severity of the alert or an options object.

Confirm

To show a confirmation to the user, use the confirm function. It takes one options parameter:

Property	Required	Description
title	no	The title of the confirmation.
message	yes	The message of the confirmation.
yes	no	The caption of the button to accept. If not provided the yes property of strings is used. The default is "Yes".
no	no	The caption of the button to deny. If not provided the no property of strings is used. The default is "No". If you pass null, the button is not displayed.

This function returns a Promise. It will be resolved if the confirmation is accepted and rejected if the confirmation is denied.

Choose

To show a choice to the user, use the choose function. It takes one options parameter:

Property	Required	Description
title	no	The title of the choice.
options	yes	The possible choices.
type	no	The optional type of the options to distinguish when rendering.
cancelCaption	no	The caption of the cancel action. If not provided the cancel property of strings is used. The default is "Cancel".
extra	no	Optional custom data.

This function returns a Promise. It will be resolved with the selected option and rejected if the choice is cancelled.

The choose function is a generic function. So you can provide a custom type for your options. The generic parameter is optional.

Your custom type must have a key property of type string | number.

interface CustomOption {
    key: string | number,
    data: MyData,
}

ConfirmService.choose<CustomOption>({
    options: [
        { key: "1", data: myData1 },
        { key: "2", data: myData2 },
        { key: "3", data: myData3 }
    ]
});
