What is NAPI-RS and How to Use It with SWC?

What is NAPI-RS?

NAPI-RS is a library written in Rust that is used to develop Node.js addons. This library allows developers to create high-performance applications and bridges the gap between JavaScript and Rust, enabling you to take advantage of the best features of both languages.

By combining Node.js with Rust, it is possible to develop large-scale, performance-oriented applications. NAPI-RS serves as a guide in this area, ensuring that code developed with Rust can work seamlessly with Node.js.

My Contribution to SWC

SWC is a rapidly growing JavaScript/TypeScript compiler written in Rust. While contributing to SWC, I worked on making error formats configurable in the minify_sync function. This change provides flexibility in error reporting formats, giving developers more control.

My Contribution: Making Error Formats Configurable

Related PR

The contribution I made to the SWC project focuses on making error formats configurable. Here’s a summary of the changes:

• Added the ErrorFormatConfig enum to enable configuration of the ErrorFormat used in the minify_sync function.
• Updated the minify_sync function to accept an optional error_format parameter, which can be set to “normal,” “json,” or “color.”
• If the error_format parameter is not provided, it defaults to ErrorFormat::Normal.
• This change makes error formats more flexible, allowing developers to choose different error formats based on their needs.

Code Example

Below is an example of how the minify_sync function can be used:

const result = minify_sync(codeBuffer, optsBuffer, "json");
