Visual Studio es una herramienta poderosa para desarrolladores, pero a veces nuestro código HTML puede volverse desordenado y difícil de leer. Para mantener nuestro código organizado, podemos utilizar la función de formateo de Visual Studio.
Hay varias formas de formatear código HTML en Visual Studio, pero la forma más común es utilizar el menú "Editar" y seleccionar "Formatear código". Esto aplicará las reglas de formateo de Visual Studio al código seleccionado.
La función de formateo de Visual Studio también puede ser configurada para adaptarse a nuestras preferencias personales. Por ejemplo, podemos cambiar el tamaño de los espacios entre las etiquetas HTML o configurar la indentación de los códigos.

Code Formatters
Code formatters are a must-have tool for any developer working with HTML in Visual Studio. They help keep your code clean and consistent, making it easier to collaborate with others and maintain your project over time.
Visual Studio Code has a built-in HTML formatter based on js-beautify, which can be accessed using the Format Document command ⇧⌥F (Windows Shift+Alt+F, Linux Ctrl+Shift+I). This will format the entire file, or you can use the Format Selection⌘K ⌘F (Windows, Linux Ctrl+K Ctrl+F) command to format just the selected text.

If you want more control over the formatting, you can customize the settings in the VS Code settings. For example, you can set the html.format.wrapLineLength to control the maximum amount of characters per line.
If you prefer to use a different formatter, such as Prettier, you can install the extension in Visual Studio Code and configure it to your liking. Prettier has a simple configuration file, .prettierrc, where you can specify your formatting rules.
One of the key features of Prettier is its automatic formatting, which reformats the code according to the rules when you save the file. This ensures that the code always follows the same style without requiring manual intervention.
Here are some key features of Prettier:
- Automatic formatting: Prettier reformats the code according to the rules when you save the file.
- Support for multiple languages: Prettier supports a variety of programming languages, including HTML, CSS, and JavaScript.
- Default opinions: Prettier has strong opinions about how the code should be formatted, which makes it easy to get started.
- Simple configuration: Prettier has a simple configuration file, .prettierrc, where you can specify your formatting rules.
- Integration with development tools: Prettier integrates well with various development tools and editors, including Visual Studio Code.
- Extensibility: Prettier is extensible, allowing you to customize certain aspects of its behavior to suit your needs.
By using a code formatter like Prettier, you can save time and effort in maintaining your codebase and ensure that it remains clean and consistent.
Archivo .prettierrc
The archivo .prettierrc is a configuration file used by Prettier, a code formatting tool. This file allows you to personalize the rules and settings of Prettier according to your project's specific needs.

The archivo .prettierrc is in JSON format and can contain various options for configuration. For example, you can specify whether to use single quotes or double quotes, whether to add semicolons, and the indentation width.
Here are some examples of rules you can establish in the archivo .prettierrc:
- "singleQuote": true indicates that Prettier will use single quotes instead of double quotes.
- "semi": false means that no semicolons will be added to the end of declarations.
- "tabWidth": 2 sets the indentation equivalent to a tabulator to 2 spaces.
- "printWidth": 80 specifies that the maximum line length before applying formatting will be 80 characters.
You can adjust these settings according to your project's preferences and standards. The archivo .prettierrc is placed in the project's root directory and is used to configure Prettier according to the project's specific needs.
Indentation and Formatting
You can use the Format Document command ⇧⌥F (Windows Shift+Alt+F, Linux Ctrl+Shift+I) to format the entire file, or the Format Selection⌘K ⌘F (Windows, Linux Ctrl+K Ctrl+F) command to just format the selected text.
The HTML formatter in Visual Studio Code is based on js-beautify, which offers various formatting options. You can access these options by going to the VS Code settings.
To configure the HTML formatter, you can set the following options:
- html.format.wrapLineLength: Maximum amount of characters per line.
- html.format.unformatted: List of tags that shouldn't be reformatted.
- html.format.contentUnformatted: List of tags, comma separated, where the content shouldn't be reformatted.
Here are some additional tips for formatting HTML code in Visual Studio Code:
- The formatter doesn't format the tags listed in the html.format.unformatted and html.format.contentUnformatted settings.
- Embedded JavaScript is formatted unless 'script' tags are excluded.
- You can use a different formatter by defining "html.format.enable": false in your settings.
Visual Studio Code offers several alternative formatters, including Prettier, which can be installed as an extension.
Evita Errores Comunes Con La Indentación
Mezclar espacios y tabulaciones para la indentación puede causar confusiones y problemas de visualización en diferentes editores y plataformas. Es recomendable elegir uno y mantener la consistencia en todo el proyecto.
La indentación para formatear código puede parecer simple, pero hay errores comunes que debes evitar para asegurarte de que tu código funciona correctamente y sea legible.
Usar tanto espacios como tabulaciones para la indentación es uno de los errores más comunes. Esto puede causar problemas en diferentes editores y plataformas.
Alt + Shift + F es un atajo para acomodar la indentación del código.

Extensions and Tools
To formatear codigo html en Visual Studio, you can install extensions to add more functionality. Go to the Extensions view and type 'html' to see a list of relevant extensions.
Some popular extensions include CSS, SCSS, and Less support, as well as Emmet, the essential toolkit for web-developers. Emmet can help with auto-completing code, including closing parentheses, brackets, and semicolons.
To install the Prettier Code Fomatter extension, follow these steps:
- 01 Instalar la extencion Prettier Code Fomatter de VSC
- 02 En VSC hacer el comando shift+comand+p (mac) o shift+control+p (windows)
- 03 Una vez que tenemos abierta la paleta de comandos debemos escribir lo siguite: >format document
- 04 Si cuentas con otras extenciones instaladas, posiblemente te salga una ventana emergente diciendo que tienes varios formateadores.
- 05 Ahora ya puedes utilizar el comando para formatear el código, shift + alt + f (mac y windows).
Emmet Snippets
Emmet snippets are a game-changer for anyone who spends a lot of time writing code. VS Code supports Emmet snippet expansion, which means you can expand abbreviations into full code snippets with just a few keystrokes.
Emmet abbreviations are listed along with other suggestions and snippets in the editor auto-completion list. This makes it easy to find and use the abbreviations you need.
You can find valid Emmet abbreviations in the HTML section of the Emmet cheat sheet. I've found it really helpful to keep this cheat sheet handy when I'm working on a new project.
If you want to use HTML Emmet abbreviations with other languages, you can associate one of the Emmet modes with other languages using the emmet.includeLanguages setting. This setting takes a language identifier and associates it with the language ID of an Emmet supported mode.
