MobileFrontend Extension

The MobileFrontend extension adds a mobile view to your mediawiki instance.

Installation

See https://www.mediawiki.org/wiki/Extension:MobileFrontend#Installation

Development

Directory structure

• resources/: Files for PHP consumption.
• src/: Files to be processed by Webpack.

Coding conventions

Please follow the coding conventions of MobileFrontend: https://www.mediawiki.org/wiki/MobileFrontend/Coding_conventions

Git hooks

Git hooks are provided by default to assist with adhering to JavaScript code standards, optimizing PNG files, etc. Running these hooks requires node.js, NPM, and grunt.

Install like so:

npm install

If you are not running Vagrant, be sure to set your MEDIAWIKI_URL env variable to your local index path, e.g. MEDIAWIKI_URL=http://localhost/index.php/

Committing

Commits are important as they give the reviewer more information to successfully review your code and find errors or potential problems you might not have thought of.

Commits are also useful when troubleshooting issues and refactoring. If it's not clear why a line of code is in the repository important bug fixes could be lost.

Commits should be as minor as possible. Please avoid removing unrelated console.log statements, fixing unrelated whitespace etc. do that in a separate commit which mentions the word cleanup.

First line commit should summarise the commit with bug it fixes if applicable. e.g. Fix problem with toggling see bug x.

Second line should be blank. Third line should go into detail where necessary providing links to blog posts/other bugs to provide more background. Mention the platforms/browsers the change is for where necessary, e.g.:

• This is a problem on Android but not OSX, see http://<url></url> which explains problem in detail
• This is a workaround for a known bug in opera mobile see http://<url></url>

Testing

Unit tests

To run the full test suite run:

npm run precommit

To run only PHP tests:

php ../../tests/phpunit/phpunit.php "tests/phpunit/"

To run only MobileFrontend JS tests:

npm run test:unit

Releasing

A new version of MobileFrontend is released every two weeks following the Wikimedia release train if there are new changes.

MobileFrontend follows the version naming from MediaWiki.

Configuration options

MobileFrontend

The following configuration options will apply to all skins operating in useformat=mobile mode.

$wgMFEnableXAnalyticsLogging

Whether or not to enable the use of the X-Analytics HTTP response header. This header is used for analytics purposes.

See: https://www.mediawiki.org/wiki/Analytics/Kraken/Data_Formats/X-Analytics

• Type: Boolean
• Default: false

$wgMFUsePreferredEditor

Use the user's preferred editor (i.e. visual editor or source editor) on first load. Uses the visualeditor-editor user option.

• Type: Boolean
• Default: false

$wgMFEnableMobilePreferences

Enable mobile preferences in Special:Preferences (currently only accessible in desktop). Currently this allows users to disable many of mobile's special page optimisations.

• Type: Boolean
• Default: false

$wgMFUseDesktopSpecialHistoryPage

Enables the desktop version of the history page if set to true. If set to false, the mobile version will be enabled but can still be overridden by the user's mobile preferences option.

• Type: Array
• Default:

  [
    // Enable mobile version of history page for all users by default
    'base' => false,
    'beta' => false,
    'amc' => false,
  ]

$wgMFEnableJSConsoleRecruitment

Controls whether a message should be logged to the console to attempt to recruit volunteers.

• Type: Boolean
• Default: false

$wgMFIsBannerEnabled

Whether or not the banner experiment is enabled.

See: https://www.mediawiki.org/wiki/Reading/Features/Article_lead_image

• Type: Boolean
• Default: true

$wgMFContentProviderClass

Name of PHP class that is responsible for formatting HTML for mobile. Must implement IContentProvider.

• Type: string
• Default: DefaultContentProvider

MFContentProviderTryLocalContentFirst

When using a ContentProvider in MFContentProviderClass, specify whether you want to allow local content as well as provided content. This is useful if you are wanting to run Selenium browser tests against locally created content but also have the benefit of testing content on a production wiki.

• Type: boolean
• Default: true

MFContentProviderScriptPath

When set will override the default script path to a foreign content provider e.g. https://en.wikipedia.org/w will route queries (e.g. API) to English Wikipedia.

Note, this will make the wiki read only. Non-anonymous HTTP requests will throw CORS error. This may also cause compatibility problems with other extensions. This should not be used in production, it is strictly for development purposes.

• Type: string
• Default: ''

$wgMFMwApiContentProviderBaseUri

URL to be used by the MwApiMobileFormatter class. Points to a MediaWiki API that can be queried to obtain content.

• Type: string
• Default: https://en.wikipedia.org/w/api.php

$wgMFAlwaysUseContentProvider

When enabled the ContentProvider will run on desktop views as well as mobile views.

• Type: boolean
• Default: false

$wgMFMobileFormatterOptions

This provides options for the MobileFormatter.

• headings: is a list of html tags, that could be recognized as the first heading of a page. This is an interim solution to fix Bug T110436 and shouldn't be used, if you don't know, what you do. Moreover, this configuration variable will be removed in the near future (hopefully).

• maxImages - if a page has more than this number of image tags then the formatter will not run

• maxHeadings - if a page has more than this number of heading tags then the formatter will not run

• Type: Object

• Default: { headings: ['h1', 'h2', 'h3', 'h4', 'h5', 'h6'], maxImages: 1000, maxHeadings: 4000 }

$wgMFSiteStylesRenderBlocking

If set to true, styles inside MediaWiki:Mobile.css will become render blocking.

This is intended for situations where the TemplateStyles extension cannot be used. When enabled, this may increase the time it takes for the mobile site to render, depending on how large MediaWiki:Mobile.css is for your wiki.

• Type: Boolean
• Default: false

$wgMFSchemaSearchSampleRate

Defines the sampling rate for the Search schema.

• Type: Number
• Default: 0.001

$wgMFSpecialCaseMainPage

If set to true, main page HTML will receive special massaging.

See https://m.mediawiki.org/wiki/Mobile_Gateway/Mobile_homepage_formatting

Use is discouraged as it leads to unnecessary technical debt and on the long term the goal is to deprecate usage of this config variable. Use at your own risk!

If this feature is enabled you can disable it temporarily by appending ?debug=1&mfnolegacytransform=1 to the main page URI.

• Type: Boolean
• Default: false

$wgMFMobileHeader

Requests containing header with this name will be considered as coming from mobile devices.

  ]

$wgMFLazyLoadImages

Do load images in pages lazily. Currently it doesn't affect HTML-only clients (only JS capable ones) and it lazy loads images when they come close to the viewport.

• Type: Array
• Default:

  [
    // These will enable lazy loading images in beta mode
    'beta' => false,
    // These will enable lazy loading images in all modes
    'base' => false,
  ]

$wgMFMobileFormatterNamespaceBlacklist

Array of namespaces that blacklists certain namespaces from applying mobile transformations to page content. This will disable lazy loading images and references; special casing and section formatting on the given page. MFRemovableClasses will not apply for any blacklisted pages.

• Type: Array

• Type: Array
• Default:

  [
    'name' => 'prefixsearch',
    'prefix' => 'ps',
  ]

$wgMFMinCachedPageSize

Pages with smaller parsed HTML size are not cached. Set to 0 to cache everything or to some large value to disable caching completely.

• Type: Integer
• Default: 64 * 1024

$wgMFAutodetectMobileView

Set this to true to automatically show mobile view depending on people's user-agent.

WARNING: Make sure that your caching infrastructure is configured appropriately, to avoid people receiving cached versions of pages intended for someone else's devices.

• Type: Boolean
• Default: true

$wgMFVaryOnUA

Set this to true, if you want to send User-Agent in the Vary header. This could improve your SEO ranking.

WARNING: You should set this to true only, if you know what you're doing!

CAUTION: Setting this to true in combination with a (frontend)caching layer (such as Varnish) can have a huge impact on how your caching works, as it now caches every single page multiple times for any possible/different User Agent string!

• Type: Boolean
• Default: false

$wgMFShowMobileViewToTablets

Controls whether tablets should be shown the mobile site. Works only if $wgMFAutodetectMobileView is true.

• Type: Boolean
• Default: true

$wgMobileUrlTemplate

Template for mobile URLs.

This will be used to transcode regular URLs into mobile URLs for the mobile view.

It's possible to specify the mobileness of the URL in the host portion of the URL.

You can either statically or dynamically create the host-portion of your mobile URL. To statically create it, just set $wgMobileUrlTemplate to the static hostname. For example:

$wgMobileUrlTemplate = "mobile.mydomain.com";

Alternatively, the host definition can include placeholders for different parts of the host section of a URL. The placeholders are denoted by %h and followed with a digit that maps to the position of a host-part of the original, non-mobile URL. Take the host en.wikipedia.org for example. %h0 maps to en, %h1 maps to wikipedia, and %h2 maps to org. So, if you wanted a mobile URL scheme that turned en.wikipedia.org into en.m.wikipedia.org, your URL template would look like:

%h0.m.%h1.%h2

• Type: String
• Default: ''

$wgMobileFrontendFormatCookieExpiry

• Type: Boolean
• Default: true

$wgMFStopRedirectCookieHost

Set the domain of the stopMobileRedirect cookie.

If this value is not set, it will default to the top domain of the host name (e.g. en.wikipedia.org = .wikipedia.org)

If you want to set this to a top domain (to cover all subdomains), be sure to include the preceding . (e.g. yes: .wikipedia.org, no: wikipedia.org)
