ReactJS Component Names Must Begin with Capital Letters?

When working with ReactJS, it is important to follow certain naming conventions to ensure consistency and readability in your code. One such convention is that ReactJS component names must begin with a capital letter. In this blog post, we will explore why this convention exists and how to adhere to it in your ReactJS projects.

Why Do ReactJS Component Names Need to Start with a Capital Letter?

The reason behind this naming convention is that ReactJS treats components starting with lowercase letters as DOM tags. For example, if you have a component named “button”, ReactJS will assume that it is an HTML button element rather than a custom React component.

By starting component names with a capital letter, you can differentiate them from regular HTML tags and make it clear that they are React components. This convention helps to avoid confusion and maintain a consistent naming pattern throughout your codebase.

How to Adhere to the Naming Convention?

1. Class Components:

When creating a class component in ReactJS, make sure to start the component name with a capital letter. Here’s an example:

class MyComponent extends React.Component {
  // component code here
}

1. Functional Components:

For functional components, the same naming convention applies. Begin the component name with a capital letter. Here’s an example:

function MyComponent() {
  // component code here
}

1. Exporting Components:

When exporting a component, ensure that the exported name also starts with a capital letter. This is important for importing the component correctly in other files. Here’s an example:

export class MyComponent extends React.Component {
  // component code here
}

Alternative Solution:

If you have a specific reason for not adhering to the naming convention, you can use the “displayName” property to override the default behavior. This property allows you to specify a custom name for your component. However, it is generally recommended to follow the naming convention for better code readability and maintainability.

class myComponent extends React.Component {
  // component code here
}

myComponent.displayName = "MyComponent";

Conclusion:

In conclusion, ReactJS component names must begin with a capital letter to differentiate them from regular HTML tags. By following this naming convention, you can ensure clarity and consistency in your codebase. Remember to start both class and functional components with a capital letter and export them accordingly. Happy coding!
