Introduction

The goal for this project roughly aligns with the WinterTC Minimum Common Web Platform API. Kiesel itself only provides an implementation of ECMA-262 and ECMA-402, other commonly available APIs like console will be implemented here.

Build

This is included in the kiesel CLI by default, follow the instructions in the main repo.

To include this runtime in your own project using Kiesel for JS evaluation:

1. Add the dependency to your build.zig.zon

2. Supply the kiesel module import:

   constkiesel=b.dependency("kiesel");constkiesel_runtime=b.dependency("kiesel-runtime");kiesel_runtime.module("kiesel-runtime").addImport("kiesel",kiesel.module("kiesel"));

3. Add bindings to an object (usually the global object) as follows:

   constkiesel_runtime=@import("kiesel-runtime");// ...
   trykiesel_runtime.addBindings(realm,global_object);
