AppCode 2018.3 Help

JavaScript Documentation Look-Up

AppCode shows you reference for standard JavaScript APIs, for symbols from your project and from its dependencies, as well as for symbols defined in external libraries. You can view the documentation for symbols in the Documentation pop-up window, get information on method parameters, and open documentation on external sites if links to them are available.

To view documentation for a symbol at caret

  • Press F1 or choose View | Quick Documentation Lookup on the main menu. The reference for the symbol is shown in the Documentation pop-up window.
    • For a project symbol or for a symbol from the project dependencies, AppCode generates the documentation from the corresponding JSDoc comment.

    • For a standard JavaScript object or method, AppCode shows the corresponding JSDoc comment from the built-in TypeScript definition files (d.ts). These files are bundled with AppCode and updated on a regular basis.

    • If no comment is found in the d.ts files, AppCode shows a summary from the corresponding MDN article.

To view the MDN documentation for a symbol at caret, do one of the following:

  • In the Documentation window (F1), click the link at the bottom of the window:

  • Press ⇧F1 or choose View | External Documentation on the main menu.

To view documentation for a third-party JavaScript library

  1. Download the required library or framework, configure it as an external JavaScript library, and specify the link to its external documentation, see Configuring a custom third-party JavaScript library for details.

  2. Position the cursor at the symbol in question and press ⇧F1 or choose View | External Documentation on the main menu.

To view documentation for an npm package

  • In a package.json file or in a require or import statement, position the cursor at the name of the package and press F1

  2. Select the Show the documentation popup checkbox and specify the elapsed time.

To change the font size of quick documentation, do one of the following:
