</note>Integration with Prettier
This feature demonstrates how to integrate the XML plugin with Prettier. By adding the plugin to your Prettier configuration, you can ensure that XML files are formatted according to the same rules as your other code.
module.exports = {
plugins: [require('@prettier/plugin-xml')],
xmlWhitespaceSensitivity: 'ignore'
};xml-formatter is a standalone library for formatting XML files. Unlike @prettier/plugin-xml, it does not integrate with Prettier but can be used independently to format XML strings or files.
pretty-data is a package that provides functions to pretty-print XML, JSON, and CSS data. It offers more versatility in terms of data types but does not integrate with Prettier like @prettier/plugin-xml.
xml-beautifier is another standalone XML formatter. It focuses solely on XML and provides a simple API for beautifying XML strings. It lacks the integration with Prettier that @prettier/plugin-xml offers.
@prettier/plugin-xml is a prettier plugin for XML. prettier is an opinionated code formatter that supports multiple languages and integrates with most editors. The idea is to eliminate discussions of style in code review and allow developers to get back to thinking about code design instead.
To run prettier with the XML plugin, you're going to need node (version 8.3 or newer).
If you're using the npm CLI, then add the plugin by:
npm install --save-dev prettier @prettier/plugin-xml
Or if you're using yarn, then add the plugin by:
yarn add --dev prettier @prettier/plugin-xml
The prettier executable is now installed and ready for use:
./node_modules/.bin/prettier --write '**/*.xml'
Below are the options (from src/plugin.js) that @prettier/plugin-xml currently supports:
| API Option | CLI Option | Default | Description |
|---|---|---|---|
printWidth | --print-width | 80 | Same as in Prettier (see prettier docs). |
tabWidth | --tab-width | 2 | Same as in Prettier (see prettier docs). |
xmlSelfClosingSpace | --xml-self-closing-space | true | Adds a space before self-closing tags. |
xmlWhitespaceSensitivity | --xml-whitespace-sensitivity | "strict" | How to handle whitespaces. Options are "strict" and "ignore". |
Any of these can be added to your existing prettier configuration file. For example:
{
"tabWidth": 4
}
Or, they can be passed to prettier as arguments:
prettier --tab-width 4 --write '**/*.xml'
You can use two special comments to get prettier to ignore formatting a specific piece of the document, as in the following example:
<foo>
<!-- prettier-ignore-start -->
< this-content-will-not-be-formatted />
<!-- prettier-ignore-end -->
</foo>
