Why Use Zustand for Forms?
Zustand makes it easy to:
- Share form data across steps and components
- Avoid prop-drilling
- Reset, patch, and validate input centrally
- Build reactive UIs around step-based workflows
Itβs an ideal replacement for useReducer() or heavy form libraries in multi-step flows.
Creating a Store for Form State
Letβs define a simple multi-step form store:
import { create } from "zustand";
type FormState = {
step: number;
data: {
name?: string;
email?: string;
password?: string;
};
next: () => void;
back: () => void;
updateField: (field: keyof FormState["data"], value: string) => void;
reset: () => void;
};
export const useFormStore = create<formstate>((set) => ({
step: 1,
data: {},
next: () => set((s) => ({ step: s.step + 1 })),
back: () => set((s) => ({ step: s.step - 1 })),
updateField: (field, value) =>
set((s) => ({ data: { ...s.data, [field]: value } })),
reset: () => set({ step: 1, data: {} }),
}));
Managing Multi-Step Navigation
In your components:
const step = useFormStore((s) => s.step);
const next = useFormStore((s) => s.next);
const back = useFormStore((s) => s.back);
{
step === 1 && <stepone></stepone>;
}
{
step === 2 && <steptwo></steptwo>;
}
Trigger actions:
<button onclick="{next}">Next</button>
<button onclick="{back}">Back</button>
Validating Fields and Conditional Steps
You can implement validation logic before moving forward:
const { data, next } = useFormStore();
const handleNext = () => {
if (!data.email?.includes("@")) {
alert("Email is invalid");
return;
}
next();
};
Resetting or Submitting the Form
const reset = useFormStore((s) => s.reset);
const formData = useFormStore((s) => s.data);
// Example on final step
const handleSubmit = () => {
api.submitForm(formData);
reset();
};
Summary
- Zustand is perfect for managing wizard forms
- Centralizes form state, steps, and actions
- Avoids deeply nested props or form libraries
- Enables progressive validation and conditional steps
