Package Exports

@wessberg/typescript-language-service

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@wessberg/typescript-language-service) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

TypescriptLanguageService

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.

Usage

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

Dependencies

TypescriptLanguageService is built to fit dependency injection systems. Thus, it requires three services to be constructor-injected: implementations of IModuleUtil, IFileLoader and IPathUtil. You can npm-install both of them: npm install @wessberg/moduleutil, npm install @wessberg/fileloader and npm install @wessberg/pathutil and either pass them on to the constructor or add them to your dependency injection system.
