# SnackBar
This component is embedded in the default layout. It remains hidden watching for changes in vuex status 'mapo/app/snackbar'. If a message is gained from the vuex getter, it shows up revealing the message.
To open the snakbar from wherever you want, you can refer to this.$mapo.$snack.open;
# Example usage:
this.$mapo.$snack.open({
message: "Only one file can be uploaded at a time..",
color: "error",
});
