Manual:Composer.json best practices/es

When creating a composer.json file for your extension/library/etc that will be used inside MediaWiki, here are a few best practices to follow. You should also run composer validate, which will point out schema errors.

Configuración

prepend-autoloader: false. Composer's autoloader is slower than MediaWiki's, and most of the classes being loaded are likely to be found inside MediaWiki, so append the Composer autoloader instead of prepending it. Véase esto para más detalles.
optimize-autoloader: true. No reason not to optimize.

Buen ejemplo: mediawiki/core

Dependencias

Dependencies should be pinned to a specific version number or sha1 commit if a tag isn't available.

Naming

Libraries hosted in Gerrit or by the Wikimedia GitHub account should typically be published under the "wikimedia" namespace (e.g. "wikimedia/cdb", "wikimedia/simplei18n"). The use of the "mediawiki" namespace should be reserved for extensions and other intrinsically MediaWiki related components (bot frameworks, etc). Projects hosted at GitHub under an independent organization are encouraged to adopt a similar convention of an organization namespace to be applied consistently across the libraries published by the group.

Autores

Major authors to the project should be documented in the "authors" property. At least the name and email fields should be filled out.

Extensions and skins

Extensiones

Extension names should be all lowercase with hyphens as word separators. For example:

Extensión:WikiEditor --> mediawiki/wiki-editor
Extensión:MassMessage --> mediawiki/mass-message

To make themselves installable, a dependency upon "composer/installers" with version >= 1.0.1 is required (a reasonable value for this field is "^2|^1.0.1"), and the type needs to be set to "mediawiki-extension".

Good example: Bootstrap extension

Skins

Mainly the same as extensions, except the type should be "mediawiki-skin". The names should end with a suffix of "-skin".

Because Composer uses lowercase names for packages (e.g. mediawiki/vector-skin), the extra.installer-name property must be set to the uppercase name (e.g. Vector) so it is cloned in the right directory.

Buen ejemplo: mediawiki/skins/Vector

Overlaps with extension.json and skin.json

Extensions and skins register information about themselves using an extension.json or skin.json file. Some metadata fields in these files overlap, including:

homepage vs. url
license vs. license-name

The redundancy of data between extension/skin.json and composer.json has been discussed (see <translate> task <tvar name=1>T89456</tvar></translate>), but current consensus is that it is unavoidable.
