如何在 mui v5 Snackbar 中动态创建多个警报

Question

I am calling an API to do few actions.
I want to take the response of each action and show it inside Snackbar/alert.

I am able to show only the first response and nothing else even after iterating the messages in a map.

Here is my business logic calling the api

try {
      const deletedUser = await deleteUser({ username: username });
      [deletedUser.data.status.action1, deletedUser.data.status.action2].map(
        (msg) =>
          setNotify({
            isOpen: true,
            message: msg,
            type: "success",
          })
      );
    } catch (error) {}

setNotify will open the Snackbar with the alerts

import React from "react";
import { Snackbar, Alert } from "@mui/material";

import { styled } from "@mui/material/styles";

const StyledSnackbar = styled((props) => <Snackbar {...props} />)(
  ({ theme }) => ({
    "& .MuiSnackbar-root": {
      top: theme.spacing(15),
    },
  })
);

export default function Notification(props) {
  const { notify, setNotify } = props;
  const handleClose = (event, reason) => {
    setNotify({
      ...notify,
      isOpen: false,
    });
  };
  return (
    <StyledSnackbar
      open={notify.isOpen}
      autoHideDuration={10000}
      anchorOrigin={{ vertical: "top", horizontal: "right" }}
      onClose={handleClose}
    >
      <Alert severity={notify.type} onClose={handleClose}>
        {notify.message}
      </Alert>
    </StyledSnackbar>
  );
}

The only issue it's only displaying the first action and nothing else.

Edit On Sandbox

I suspect the alerts are overlapping on top of each other Maybe we need to add some sort of AutoGrow prop

You have to use notistack as described in the MUI doc :

This example demonstrates how to use notistack . notistack has an imperative API that makes it easy to display snackbars, without having to handle their open/close state. It also enables you to stack them on top of one another (although this is discouraged by the Material Design guidelines).

Start by wrapping your app inside a SnackbarProvider component then use useSnackbar hook to access to enqueueSnackbar in order to add a snackbar to the queue to be displayed:

App.js

import "./styles.css";
import React from "react";
import { SnackbarProvider } from "notistack";
import Notification from "./Notification";

export default function App() {
  return (
    <SnackbarProvider maxSnack={3}>
      <div className="App">
        <h1>Dynamic Snackbar Alerts</h1>
        <Notification />
      </div>
    </SnackbarProvider>
  );
}

Notification.js

import React from "react";
import { Button } from "@mui/material";
import { useSnackbar } from "notistack";

export default function Notification(props) {
  const { enqueueSnackbar } = useSnackbar();

  const handleClick = async () => {
    try {
      const deletedUser = await deleteUser({ username: username });
      [deletedUser.data.status.action1, deletedUser.data.status.action2].forEach((msg) => {
          enqueueSnackbar(msg, {
            variant: "success",
            autoHideDuration: 10000,
            anchorOrigin: { vertical: "top", horizontal: "right" }
          });
      });
    } catch (error) {}
  };

  return (
    <Button variant="outlined" onClick={handleClick}>
      Generate Snackbar Dynamicly
    </Button>
  );
}
