How do I install ChakraCore-Delphi in my Delphi project?

Clone the repository with submodules, download ChakraCore binaries from the specified release page, and add the source files to your project path. Follow the README steps for platform-specific setup.

ChakraCore-Delphi vs DWS for Delphi: which is better?

ChakraCore-Delphi uses Microsoft's engine for high performance and modern JS support, while DWS is a native Pascal script engine. Choose ChakraCore for JS compatibility in desktop apps, or DWS for pure Pascal integration without external dependencies.

Does ChakraCore-Delphi support async/await or ES6 modules?

It depends on ChakraCore 1.11.24, which has partial ES6 support but may not fully include newer features like async/await. Check ChakraCore's documentation for specific version capabilities.

Can I use this with Free Pascal on Linux?

Yes, the project supports x86_64-linux via Free Pascal, allowing cross-platform application development. Ensure you have the correct binaries and compiler settings as per the README.

How to handle JavaScript errors in ChakraCore-Delphi?

Use the provided Object Pascal classes to catch exceptions from JavaScript execution, similar to native error handling. Implement callbacks or checks in your Delphi code to manage errors gracefully.

Is ChakraCore still maintained by Microsoft?

ChakraCore is no longer actively developed by Microsoft, which could impact future updates, security patches, and compatibility with new JavaScript standards for this binding.

How to update to a newer version of ChakraCore?

You would need to manually update the bindings, as the project is tied to 1.11.24. Check the repository for forks or community updates, or modify the source code yourself to adapt.

What is chakracore-delphi?

ChakraCore-Delphi is a set of Delphi and Free Pascal bindings and classes for Microsoft's ChakraCore JavaScript engine. It allows developers to integrate and execute JavaScript code within Delphi and Free Pascal applications, enabling scripting capabilities and interaction with JavaScript objects directly from Object Pascal code.

Target Audience

Delphi and Free Pascal developers who need to embed a JavaScript engine into their desktop applications for scripting, automation, or extending functionality with JavaScript.

Value Proposition

It provides a native, performant, and cross-platform solution for integrating ChakraCore into Object Pascal projects, with support for multiple compilers and target platforms, making it easier to add JavaScript capabilities without relying on external tools.

Overview

Delphi and Free Pascal bindings and classes for Microsoft's ChakraCore library

Use Cases

Best For

Embedding a JavaScript engine in Delphi desktop applications
Adding scripting capabilities to Free Pascal projects
Executing JavaScript code from Object Pascal programs
Building cross-platform applications with JavaScript integration
Extending Delphi apps with JavaScript-based plugins
Integrating ChakraCore into legacy Delphi codebases

Not Ideal For

Projects requiring the latest JavaScript features (ES2020+), as it's bound to ChakraCore 1.11.24 which is outdated
Applications needing server-side JavaScript with full Node.js APIs, since it's a bare engine without Node ecosystem support
Teams using modern IDEs or frameworks incompatible with older Delphi versions, as it supports Delphi 7 or newer with potential legacy issues
Developers seeking a plug-and-play solution, due to manual download and integration of ChakraCore binaries adding setup complexity

Pros & Cons

Pros

Cross-Platform Compatibility

Supports Windows, Linux, and macOS via Free Pascal, and Windows via Delphi, enabling multi-platform desktop applications with JavaScript integration, as stated in the README for target platforms.

Multi-Compiler Support

Works with Delphi 7 or newer and Free Pascal 3.0.4 or newer, ensuring broad compatibility with legacy and modern Object Pascal projects, per the README's compiler requirements.

Native Integration

Provides Object Pascal classes that wrap ChakraCore functionality, simplifying interaction with JavaScript objects and code from Delphi without low-level binding complexities.

Performance Focus

Leverages Microsoft's ChakraCore engine, known for high-performance JavaScript execution, beneficial for scripting-intensive applications in Delphi environments.

Cons

Complex Setup Process

Requires manually downloading ChakraCore binaries from external sources and managing git submodules, adding steps compared to integrated solutions, as noted in the installation instructions.

Outdated Engine Version

Binds to ChakraCore 1.11.24, an older release that may lack support for recent ECMAScript features and optimizations, limiting modern JavaScript capabilities.

Limited Documentation

The README only covers basic installation without detailed usage examples or API references, making it challenging for new users to implement advanced features.
