JSDoc Auto-Generation in PhpStorm – No Empty Lines Before Parameters

Are you tired of manually writing JSDoc comments for your JavaScript code in PhpStorm? Do you wish there was a way to auto-generate these comments and avoid those annoying empty lines before parameters? Well, you’re in luck because in this article, we’ll show you exactly how to do just that!

What is JSDoc and Why Do I Need It?

JSDoc is a documentation generator for JavaScript that helps developers create beautiful, readable, and maintainable code. It’s an essential tool for any serious JavaScript developer, and PhpStorm has built-in support for it. But, let’s be real, writing JSDoc comments can be a tedious task, especially when you have a large codebase. That’s where auto-generation comes in.

Why Auto-Generate JSDoc Comments?

Auto-generating JSDoc comments has several benefits:

• Save time: Writing JSDoc comments manually can take hours, even days. With auto-generation, you can focus on writing code, not comments.
• Consistency: Auto-generated comments ensure consistency in your code, making it easier to read and maintain.
• Accuracy: Auto-generated comments are less prone to errors, which means fewer bugs and more reliable code.

Configuring PhpStorm for JSDoc Auto-Generation

To auto-generate JSDoc comments in PhpStorm, you need to configure the editor to use the JSDoc plugin. Here’s how:

1. Open PhpStorm and navigate to Preferences (or Settings on Windows/Linux).
2. In the Preferences window, navigate to Editor > JavaScript > Code Quality Tools.
3. Click on the (gear icon) next to JSDoc and select Configure JSDoc....
4. In the JSDoc Configuration window, select the Enable JSDoc support checkbox.
5. Configure the JSDoc options as desired (e.g., template, output directory, etc.).

Configuring the JSDoc Template

The JSDoc template determines the format and structure of your auto-generated comments. You can customize the template to fit your coding style. Here’s an example of a basic template:

/**
 * {{description}}
 *
 * @param {{paramName}} {{paramType}} - {{paramDescription}}
 * @returns {{returnType}} - {{returnDescription}}
 */

You can customize this template to include or exclude specific parameters, change the formatting, and more.

Generating JSDoc Comments in PhpStorm

Now that you’ve configured PhpStorm for JSDoc auto-generation, let’s generate some comments!

Place your cursor on a function or variable declaration, and then:

1. Press Alt + Shift + J (Windows/Linux) or Cmd + Shift + J (Mac) to invoke the JSDoc comment generation.
2. PhpStorm will auto-generate a JSDoc comment based on the template you configured.

No Empty Lines Before Parameters!

One of the most frustrating things about JSDoc comments is the empty line before the parameters. But fear not, dear developer! You can configure PhpStorm to remove these empty lines. Here’s how:

1. In the JSDoc Configuration window, navigate to the Format tab.
2. Uncheck the Blank line before parameter checkbox.
3. Click Apply and then OK.

Now, when you generate JSDoc comments, the empty lines before parameters will be gone!

Troubleshooting Common Issues

Like with any tool, you might encounter issues with JSDoc auto-generation in PhpStorm. Here are some common issues and their solutions:

Issue	Solution
