TypescriptLanguageServiceHost

A host-implementation of Typescripts LanguageService.

Installation

Simply do: npm install @wessberg/typescript-language-service.

What is it

This is an implementation of Typescript's LanguageService. It can resolve .ts and .js files and builds up an AST from both kinds of files. It can recursively add all imports of a module to the AST if required. Otherwise it can be used to parse and generate Statements, Expressions and (Typescript) Nodes from source code.

Additionally, if a file is added (either directly or automatically) that has a definition file (.d.ts) with the same name in the same directory, it will merge the two before adding the file to the LanguageService.

Usage

const languageService = new TypescriptLanguageServiceHost();
languageService.addFile({
	path: "foo.ts",
	content: `
		import {bar} from "./bar";
		export const foo = bar + 2;
	`,
	addImportedFiles: true
});
