Getting Started with React Time Picker: A Beginner's Tutorial

Time Picker is a user-friendly TimePicker component that allows users to select specific hours and minutes in your React app. This time picker is a crucial component in many React apps, especially when you need to handle time values. The Time Picker is a part of a larger family of date and time-handling components, which also includes the React Date Picker.

Time Picker is a versatile component that can be customized to fit the needs of your React app. For example, you can set a default time, specify a time range, or even disable the time picker in certain situations. The time values selected by the user are easy to manage, making it a valuable tool for any React app.

‍

Why use Time Picker?

In a React app, dealing with time values can be a bit tricky. This is where the Time Picker comes in. By using this TimePicker component, you can provide a consistent and user-friendly way for users to input time values.

Whether you're creating a booking form or a time-tracking app, the Time Picker can save you a lot of time and code. Instead of creating your own time picker from scratch, you can simply import TimePicker from the react-time-picker package and use it in your app.

Moreover, Time Picker is not just about picking hours. It also supports different time formats, allowing users to input time in a format they are comfortable with. This flexibility makes the React Time Picker a must-have component in your React app.

‍

Importance of Time Picker in Web Applications

In many web applications, time input is a common requirement. Whether it's for scheduling appointments, setting reminders, or tracking time, a reliable time picker is essential.

React Time Picker shines in this aspect. It provides a clean, intuitive interface for users to select time. The Time Picker component is not just about appearance, though. It also ensures that the time values entered by the user are valid, taking care of the validation for you.

Furthermore, the Time Picker is highly customizable. You can style it to match the look and feel of your app, hide it when not in use, or even disable it in certain situations. This level of control makes the React Time Picker a valuable addition to any React app.

Getting Started with Time Picker

‍

Prerequisites for using Time Picker

Before we dive into using the Time Picker, there are a few prerequisites you need to have in place. Firstly, you need to have a basic understanding of React and how to create components in a React app. Secondly, you need to have a React app set up where you can implement the Time Picker. Lastly, you need to have Node.js and npm installed on your machine, as we will be using npm to install the react-time-picker package

‍

Installation and setup of React Time Picker

To install react-time-picker package, you need to run the following command in your terminal:

Copy
1
2
     npm install react-time-picker
     

Once you've installed the package, you can import TimePicker into your component file like this:

Copy
1
2
     import TimePicker from 'react-time-picker';
     

‍

Basic structure of a Time Picker

Now that you've installed and imported the react-time-picker, let's look at the basic structure of a React Time Picker component.

In its simplest form, a Time Picker can be implemented as follows:

Copy
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
     import React from 'react';
    import TimePicker from 'react-time-picker';
    
    function App() {
      return (
        <div>
          <TimePicker
            onChange={this.onChange}
            value='10:00'
          />
        </div>
      );
    }
    
    export default App;
     

In the above example, we have a TimePicker component with two props: onChange and value. The onChange prop is a function that will be called whenever the user changes the time. The value prop is the initial time value that the TimePicker will display.

Understanding the properties of Time Picker

‍

Time Format

Time Picker supports different time formats. By default, it uses the 24-hour format, but you can also set it to use the 12-hour format. This is done using the format prop. For example:

Copy
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
     import React from 'react';
    import TimePicker from 'react-time-picker';
    
    function App() {
      return (
        <div>
          <TimePicker
            onChange={this.onChange}
            value='10:00'
            format='hh:mm a'
          />
        </div>
      );
    }
    
    export default App;
     

In this example, the format prop is set to 'hh:mm a', which represents the 12-hour format.

‍

Default Time

You can set a default time for the TimePicker using the value prop. This is the time that will be displayed when the TimePicker is first rendered. For example:

Copy
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
     import React from 'react';
    import TimePicker from 'react-time-picker';
    
    function App() {
      return (
        <div>
          <TimePicker
            onChange={this.onChange}
            value='10:00'
          />
        </div>
      );
    }
    
    export default App;
     

In this example, the value prop is set to '10:00', so the TimePicker will display 10:00 when it's first rendered.

‍

Time Range

You can limit the range of time that can be selected by using the minDetail and maxDetail props. For example, if you want to limit the time range to hours only, you can do so like this:

Copy
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
     import React from 'react';
    import TimePicker from 'react-time-picker';
    
    function App() {
      return (
        <div>
          <TimePicker
            onChange={this.onChange}
            value='10:00'
            minDetail='hour'
            maxDetail='hour'
          />
        </div>
      );
    }
    
    export default App;
     

In this example, both minDetail and maxDetail are set to 'hour', so the user can only select the hour, not the minutes.

‍

Common Issues and their solutions

While implementing the Time Picker, you might encounter some common issues. Here are a few of them and their solutions:

Issue:

The TimePicker is not displaying the correct time.

Solution:

Make sure that the value prop is a string in the format 'hh:mm' or 'hh:mm:ss'. Also, ensure that the time is within the range specified by minDetail and maxDetail.

‍Issue:

The TimePicker is not updating when the user selects a time.

Solution:

Make sure that you're correctly handling the onChange event. The onChange prop should be a function that updates the state of your component with the new time value.

Here's an example of how to handle the onChange event:

Copy
1
2
3
4
5
6
7
8
9
10
11
12
13
14

     import React, { useState } from 'react';
    import TimePicker from 'react-time-picker';
    
    function App() {
      const [time, setTime] = useState('10:00');
    
      const onChange = (value) => {
        setTime(value);
      };
    
      return (
        <div>
          <TimePicker
            onChange={onChange}
            value={time}
          />
        </div>
      );
    }
    
    export default App;

Best practices when using Time Picker

‍

Accessibility Considerations

When using the Time Picker, it's important to keep accessibility in mind. Make sure to provide labels for the Time Picker and use semantic HTML where possible. Also, ensure that the Time Picker is usable with a keyboard.

‍

Performance optimization

To optimize the performance of the Time Picker, avoid unnecessary re-renders by using React.memo function. Also, make sure to debounce the onChange function so it doesn't fire too often and slow down your app.
