value (string): The current value of the input field. This is a controlled component, so you must update this prop whenever the onChange callback is called.
onChange (function): A callback that is called whenever the input value changes. It receives the new value as its only argument.

Usage

🚀 Here are some examples of how to use the CustomInput component:

A very basic example with only the required props

import React, { useState } from "react";
import { CustomInput } from "react-custom-inputs";

function Example() {
  const [value, setValue] = useState("");

  return <CustomInput value={value} onChange={setValue} />;
}

A more advanced example using more props!

import React, { useState } from "react";
import { CustomInput } from "react-custom-inputs";

function Example() {
  const [value, setValue] = useState("");

  const handleChange = (value: any) => {
    setValue(value);
  };

  return (
    <CustomInput
      id="my-text-input"
      value={value}
      onChange={handleChange}
      type="text"
      unitLabel="PIN"
      placeholder="Enter your PIN"
      errorText={value.length > 5 ? "The maximum PIN length is 5" : null}
      borderColor="transparent"
      width="200px"
      paddingSize={8}
      borderRadius="4px"
      noLeadingSpaces
    />
  );
}

Another example using even more props!

import React, { useState } from "react";
import { CustomInput } from "react-custom-inputs";

function Example() {
  const [weight, setWeight] = useState(0);

  const handleChangeWeight = (value: any) => {
    setWeight(Number(value));
  };

  return (
    <CustomInput
      id="my-input"
      value={weight}
      onChange={handleChangeWeight}
      type="number"
      unitLabel="kgr"
      label="Your weight"
      placeholder="Enter your weight in Kgr"
      errorText={weight < 30 ? "The minimum weight is 30 Kgr" : null}
      shadowColor="rgba(0, 0, 0, 0.15)"
      textColor="blue"
      bgColor="whitesmoke"
      borderColor="transparent"
      width="200px"
      paddingSize={12}
      borderRadius="10px"
      noLeadingSpaces
    />
  );
}

In this example:

label is set to "My Label", which might be displayed as a label for the input field.
placeholder is set to "Enter some text", which is displayed when the input field is empty.
errorText is set to "This field is required", which might be displayed if the input value is invalid.
unitLabel is set to "kg", which might be displayed next to the input field to indicate the unit of the value.
id is set to "my-input", which can be used to identify the input field in your CSS or JavaScript.
shadowColor is set to "rgba(0, 0, 0, 0.15)", which might be used to set the color of the input field's shadow.
textColor is set to "blue", which sets the color of the text in the input field.
width is set to "200px", which sets the width of the input field.
type is set to "text", which sets the type of the input field.
borderRadius is set to "8px", which sets the border radius of the input field.
noLeadingSpaces is set to true, which might be used to remove leading spaces from the input value.
borderColor is set to "gray", which sets the color of the input field's border.
bgColor is set to "lightgray", which sets the background color of the input field.
paddingSize is set to 20, which sets the padding inside the input field.

Tips

💡 Useful Tips for Validations

An easy way to validate the user input and feed the component with error text accordingly:

import React, { useState } from "react";
import { CustomInput } from "react-custom-inputs";

function Example() {
  const [value, setValue] = useState();

  const handleChange = (value: any) => {
    setValue(value);
  };

  // Basic Text length validation
  const getErrorText = () => {
    const re = /^\d{10}$/;
    return re.test(value) ? null : "The maximum PIN length is 5";
  };

  return (
    <CustomInput
      type="number"
      id="my-phone-input"
      value={value}
      onChange={handleChange}
      placeholder="Enter your phone"
      errorText={getErrorText}
    />
  );
}

Similar if for email validation:

import React, { useState } from "react";
import { CustomInput } from "react-custom-inputs";

function Example() {
  const [value, setValue] = useState();

  const handleChange = (value: any) => {
    setValue(value);
  };

  // Basic Email format validation
  const getErrorText = () => {
    const re = /\S+@\S+\.[a-zA-Z]{2,4}$/;
    return re.test(value) ? null : "Email format is not correct";
  };

  return (
    <CustomInput
      type="email"
      id="my-phone-input"
      value={value}
      onChange={handleChange}
      placeholder="Enter your phone"
      errorText={getErrorText}
    />
  );
}
