JavaScript API Support
Javy by default supports ES2023, plus partial support for additional APIs. NodeJS APIs are not supported.
This document aims to give an overview of the additional APIs provided by Javy.
In general the ultimate goal of Javy is to provide a WinterCG Common
API compatible
implementation, however, currently some APIs are not fully
compliant and therefore are provided under a custom Javy namespace or
explicitly marked as partially supported in the table below.
Compatibility table
| API | Support | Comments |
|---|---|---|
JSON | ✅ | Improved performance through SIMD JSON, when using the -J simd-json-builtins flag |
String.prototype.normalize | ✅ | |
TextDecoder | 🚧 | Partial support, not fully compliant |
TextEncoder | 🚧 | Partial support, not fully compliant |
console | 🚧 | Partial support, console.log and console.error |
Javy provides a custom Javy namespace, which includes the following
functionality:
IO: providesreadSyncandwriteSync, analogous to Node’sfsAPI.
