Please add access to Abstract Syntax Tree

Please expose Abstract Syntax Tree from Language service for TypeScript. It will be of great help to analyze code model rather then reparsing it again (as there is no way to access internal model), I want to access imported modules.

Update

Can you add a method that goes inside worker and can access the model and return the result?

        function nodeVisitor(root) {
            // .. ast related code without any closure...
            return // ... some result...
        }

        // source of nodeVisitor is passed to 
        // typescript worker
        const result = await worker.processAst( nodeVisitor.toString() );

The underlying code simply passed this function as source code, which is executed in worker’s context and result is returned either as string or or some JSON.

A worker is async background code which you don’t really have access to in a general sense from your user-land code.

@luminaxster’s idea of being able to add your own dynamic import is probably the best option here - perhaps a new function in here: https://github.com/microsoft/monaco-typescript/blob/master/src/tsWorker.ts#L235 which calls importScripts with your own URL which has a default export as a function which receives a copy of ts and and the TypeScriptWorker this instance.

https://github.com/microsoft/monaco-typescript/pull/65 would allow you to create your own webworker which can do AST stuff I the background
