ClearScriptLib

1 year ago Hi @stone89son,
ClearScript doesn't implement Node.js functionality such as node_modules path resolution or package.json support. However, if you've installed an npm package, you can use its modules from ClearScript with some setup.
Here's an example. Suppose you've installed the Lodash standard modules via npm install -g lodash-es. You can then do this:
var appDataPath = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
var nodeModulesPath = Path.Combine(appDataPath, "npm", "node_modules");
_engine.DocumentSettings.AccessFlags = DocumentAccessFlags.EnableFileLoading;
_engine.DocumentSettings.SearchPath = Path.Combine(nodeModulesPath, "lodash-es");And now you can import the Lodash modules:
_engine.AddHostType(typeof(Console));
_engine.Execute(new DocumentInfo { Category = ModuleCategory.Standard }, @"
import * as _ from 'lodash';
const result = _.defaults({ 'a': 1 }, { 'a': 3, 'b': 2 });
Console.WriteLine(JSON.stringify(result));
");This code produces the output {"a":1,"b":2}, as expected. Keep in mind that, unfortunately, many npm packages depend on Node.js or Web APIs and therefore can't be used from ClearScript without modification or additional setup.
Good luck!
