Changes

JavaScript API

• Add a sass.initCompiler() function that returns a sass.Compiler object which supports compile() and compileString() methods with the same API as the global Sass object. On the Node.js embedded host, each sass.Compiler object uses a single long-lived subprocess, making compiling multiple stylesheets much more efficient.

• Add a sass.initAsyncCompiler() function that returns a sass.AsyncCompiler object which supports compileAsync() and compileStringAsync() methods with the same API as the global Sass object. On the Node.js embedded host, each sass.AsynCompiler object uses a single long-lived subprocess, making compiling multiple stylesheets much more efficient.

Embedded Sass

• Support the CompileRequest.silent field. This allows compilations with no logging to avoid unnecessary request/response cycles.

• The Dart Sass embedded compiler now reports its name as "dart-sass" rather than "Dart Sass", to match the JS API's info field.
