Fk-mui NPM | npm.io

Typesafe Formik + MUI library

Formik is a form library for React
MUI is a React UI library

Both of these libraries are very popular and widely used in the React community. There are many places where we have to use both of these libraries together. This library (fk-mui) is a collection of components that are built using both of these libraries to reduce the boilerplate code and make the development process faster 🏎️ (for now only the TextField component is available 🙂).

Installation

If you are using npm

npm install fk-mui

If you are using yarn

yarn add fk-mui

If you are using pnpm

pnpm add fk-mui

Available components

FMUITextField - MUI TextField integrated with Formik

FMUITextField

This is a wrapper around the MUI TextField component integrated with Formik. It has all the props that are available in the MUI TextField component with two additional props:

name: string - name of the field
form: Formk form

name should be a key of values of form. Seat belts are on 🚗. If you are using TypeScript, it will give you an error if you pass a name that is not in the form.
This component will automatically populate onChange, onBlur, value, error and helperText for you. You don't have to do anything. Just pass the name and form props and you are good to go.

Example

import { useFormik } from "formik";
import { FMUITextField } from "formikmui";

const MyForm = () => {
  const form = useFormik({
    initialValues: {
      name: "",
    },
    onSubmit: (values) => {
      console.log(values);
    },
  });

  return (
    <form onSubmit={form.handleSubmit}>
      <FMUITextField
        name="name"
        form={form}
        label="Name"
        variant="outlined"
        sx={{ width: "100%" }}
      />
    </form>
  );
};

SSR

These components do not support Server Side Rendering because they need client interactivity. For example, the FMUITextField component needs to show errors dynamically when user changes the text input. It needs JavaScript in client side to do that.
These components are marked with "use client" and they will be rendered on client side.
