Getting Started

New to Nightmare? The most basic way to use it is with promises or callbacks. Here are a few examples:

• Native promises
• Callbacks

Nightmare and Generators

Several JavaScript libraries use generators to give you a simpler way to deal with asynchronous events. Here’s how to use Nightmare with some of them:

• vo
• co
• mocha-generators

Extending Nightmare

Nightmare may not do everything out of the box that you need it to do.

• .action() - Look here if adding a method that does a specific activity in the browser.
• .use() - Wrap several actions up for reusability in one tidy place.

Common Pitfalls

Working with an automated web browser can be complex. Here are a few common gotchas and issues you might run into while working with Nightmare:

• Asynchronous operations and loops
• Variable lifting with .evaluate()

Known Issues

Here are some known problems with Nightmare:

• Uploads
• then...catch
• Globally defined variables in injected scripts

Examples

All pages above have accompanying scripts you can actually run. To get started, you’ll need to make sure you install their dependencies first by running npm install.

After that, all the examples are runnable using node [example].
