setting also lets you change where snippets appear in the suggestions: at the top ('top'

project file.allowSyntheticDefaultImports
compiler option to true
. This tells the compiler to create synthetic default members and you get IntelliSense. React Native uses Babel behind the scenes to create the proper run-time code with default members. If you also want to do debugging of React Native code, you can install the React Native Extension.Automatic Type Acquisition
works for dependencies downloaded by npm (specified in package.json
), Bower (specified in bower.json
), and for many of the most common libraries listed in your folder structure (for example jquery-3.1.1.min.js
).allowSyntheticDefaultImports
to true.|>
) operator. However, these are currently not supported by VS Code's JavaScript language service and are flagged as errors. For users who still want to use these future features, we provide the javascript.validate.enable
setting.javascript.validate.enable: false
, you disable all built-in syntax checking. If you do this, we recommend that you use a linter like ESLint to validate your source code. Since VS Code's JavaScript support doesn't understand ES7 constructs, features like IntelliSense might not be fully accurate.
