Quick guide

You can also take a look at the live demo, if you prefer.

1. Initialize using initToast
2. Create your toast-list, using ToastProvider or useToasts, returned from initToast
3. Fire off a toast, using toast returned from initToast.

// toast.ts
import { initToast } from "@ryfylke-react/toast";

export type Toast = {
  title: string;
};

export const { toast, ToastProvider } = initToast<Toast>();

// App.tsx
import { ToastProvider, Toast } from "./toast";

const App = () => {
  return (
    <div className="App">
      <ToastProvider
        portal={document.body}
        removeToastsAfterMs={3000}
        renderToasts={RenderToasts}
      />
      <Elsewhere />
    </div>
  );
};

const RenderToasts = (props: {
  toasts: (Toast & { id: string })[];
  onRemoveToast: (toastId: string) => void;
}) => {
  return (
    <div className="toasts-container">
      {props.toasts.map((toast) => (
        <button
          key={toast.id}
          className="toast"
          onClick={() => props.onRemoveToast(toast.id)}
        >
          {toast.title}
        </button>
      ))}
    </div>
  );
}

// Elsewhere.tsx
import { toast } from "./toast";

export const Elsewhere = () => {
  return (
    <button
      onClick={() => {
        toast({ title: "Hi!" });
      }}
    >
      Toast me!
    </button>
  );
};

Reference

@ryfylke-react/toast is fully typescript supported.

TLDR:

// import { initToast } from "@ryfylke-react/toast";
type InitToast = <T>() => {
   toast: Toast<T>;
   useToasts: UseToasts<T>;
   ToastProvider: ToastProvider<T>;
   subscribeToToasts: SubscribeToToasts<T>;
}

type Toast<T> = (args: T) => void;

type UseToasts<T> = (args?: {
   onToastAdded?: (toast: T & { id: string }) => void;
   removeToastsAfterMs?: number;
}) => {
   toasts: (T & { id: string })[];
   onRemoveToast: (toastId: string) => void;
}

type ToastProvider<T> = (props: {
  renderToasts: (props: {
    toasts: (T & { id: string })[];
    onRemoveToast: (id: string) => void;
  }) => ReactElement;
  removeToastsAfterMs?: number;
  onToastAdded?: (toast: T) => void;
  portal?: undefined | HTMLElement;
}) => (ReactPortal | ReactElement);

type SubscribeToToasts<T> = (callback: (toast: T & { id: string }) => void) => (() => void);

initToast<T>

Arguments: Takes one Typescript generic to specify the desired toast interface. The generic should extend Record<string, any>.

Returns:

The following (toast, useToasts, ToastProvider & subscribeToToasts):

toast

Takes whatever interface you specified as a generic when initializing with initToast, as well as an optional argument:

• removeAfterMs - (optional) Lets you specify a delay for this specific toast to be removed after.

useToasts

Arguments:

• onToastAdded - (optional) A function that is run whenever a new toast is dispatched. Returns the toast in its argument. Useful for logging the toasts, or syncing them with an external store.
• removeToastsAfterMs - (optional) Determines if toasts should be removed from the list, and how long they should stay. (number | undefined)

Returns:

• toasts - A list of all current toasts.
• onRemoveToast - A function that takes one argument, toastId: string, and removes the given toast from the internal list.

ToastProvider

Arguments: Same arguments as useToasts, but laid out in a different manner:

• renderToasts - Takes a function that returns a ReactElement. Has the following props:
  • toasts - The list of toasts
  • onRemoveToast - A function that takes one argument, toastId: string.
• removeToastsAfterMs - (optional) An argument that lets you configure a timeout for automatically removing the toast from the list.
• onToastAdded - (optional) A function that is run whenever a new toast is dispatched. Returns the toast in its argument. Useful for logging the toasts, or syncing them with an external store.
• portal - (optional) If supplied, specifies which HTMLElement to render a portal to for renderToasts. If not supplied, no portal is rendered.

Returns: Whatever renderToasts returns.

Notes: ToastProvider is not strictly nessecary if you are using useToasts. This component is just a helper/HOC for utilizing the hook.

subscribeToToasts

Lets you subscribe to toasts outside of React. Takes one argument, callback which is a callback function that gets called whenever a new toast is added. Returns a unsubscribe function, that stops listening for events.
