Ace vs CodeMirror: What are the differences?

Introduction

Ace and CodeMirror are two popular JavaScript libraries for creating code editors in web applications. While they both offer similar functionality, they have some key differences that set them apart. In this article, we will explore six main differences between Ace and CodeMirror.

1. Architecture:

Ace uses a single JavaScript file for its core, which makes it easier to integrate into a project. On the other hand, CodeMirror provides a modular architecture, allowing developers to include only the necessary components, resulting in a smaller file size.

2. Browser Support:

Ace has better browser support compared to CodeMirror. It is compatible with all major modern browsers, including Internet Explorer 10+. CodeMirror, on the other hand, may have limited support in older browsers.

3. Extensions and Plugins:

Ace has a rich ecosystem of extensions and plugins available, offering additional features and customization options. CodeMirror also has a good selection of extensions, but it may not be as extensive as Ace.

4. Performance:

When it comes to performance, CodeMirror is known for being more lightweight and faster compared to Ace. This can make a difference, especially when dealing with larger codebases or complex editing operations.

5. Community and Documentation:

Ace has a larger and more active community compared to CodeMirror. This means that there are more resources, discussions, and examples available for Ace. Additionally, Ace has comprehensive documentation, making it easier for developers to get started and find answers to their questions.

6. Customization Options:

Both Ace and CodeMirror offer a wide range of customization options, allowing developers to tailor the editor to their specific needs. However, Ace provides more out-of-the-box customization options and themes, making it easier to achieve a desired look and feel without additional coding.

In summary, Ace and CodeMirror differ in their architecture, browser support, extensions/plugins ecosystem, performance, community/documentation, and customization options. Each library has its strengths and weaknesses, and the choice between the two depends on the specific requirements of the project.
