TypeScript

Node interpreter

In this field, specify the Node.js interpreter to use. If you choose the Project alias, AppCode will automatically use the project default interpreter from the Node interpreter field on the Node.js and NPM page .

In most cases, AppCode detects the project default interpreter and fills in the field itself. You can also choose another configured local interpreter or click and configure a new one.

TypeScript

In this field, specify the version of the TypeScript to use (AppCode displays the currently chosen version).

• By default, the typescript package from the project's node_modules folder is used.

• Bundled: choose this option to use the typescript package that is shipped with AppCode without attempting to find another one.

• Select: choose this option to use a custom typescript package instead of the one bundled with AppCode. In the dialog that opens, choose the path to the relevant package.

• If your project package manager is Yarn 2, you have to use the typescript package installed via Yarn 2. In this case, yarn:package.json:typescript is by default selected.
