Extension:QuickSurveys

The QuickSurveys extension displays in-article banners, through which users can be canvassed for their feedback.

Documentation and features
As of 2021, QuickSurveys can:
 * Rationale
 * Deploying surveys
 * Documentation on metawiki

Known problems:
 * target random readers
 * target readers of a specific page
 * ask one multiple-choice question
 * collect one or more responses to that question ("pick the best answer" vs. "check all that apply")
 * offer a link to another page (e.g., to provide information about a longer survey)


 * Some ad-blocking software blocks this extension.
 * Setting up a survey requires support from a developer.

Prerequisites
QuickSurveys depends on EventLogging and won't work without it.

Configuration
Here are configurations for the two major types of survey: an "internal survey" which displays a question and a set of possible answers in the article itself, and an "external survey" which links to another platform (e.g. Google Forms).

Defining an audience
It is possible to define audiences for a survey based edit count, whether a respondent is logged in, user registration date, and their country (based on IP).

The audience field is optional and can be omitted if you want the survey to show to everyone (as defined in coverage). You can also only include some of the parameters. For example, including just  will target users who have at least that many edits with no maximum.

Note, the audience is not included in sampling, so for example if coverage is 0.5, 50% of all users will be bucketed for the survey, but only the users in that 50% that match the audience will actually see the survey.

All audience keys are additive.

We will accept several keys:


 * minEdits: the minimum number of edits a user should have
 * maxEdits: the maximum number of edits a user should have
 * anons: is the survey targeted to anons (true) or logged-in (false) only? If undefined, both groups will potentially be included.
 * registrationStart: if the survey is targeted by registration date, user had to join on or after this date. Date is in format YYYY-MM-DD
 * registrationEnd: if the survey is targeted by registration date, user had to join before or on this date. Date is in format YYYY-MM-DD
 * countries: a list of two letter country codes that are matched against window.Geo.country
 * pageIds: a list of article IDs, the survey can only be displayed on matching pages

Survey layout
The following configuration fields control how the survey will be displayed:


 * type: external - The survey is hosted on an external website, all we show is a link.QuickSurveys "external" mode.png
 * layout: single-answer - Choices are each presented as a button. Clicking a choice will immediately submit and dismiss the survey, unless a freeform text input is enabled.Single-answer QuickSurveys survey.png
 * layout: multiple-answer - Choices are each presented as a checkbox. Multiple choices can be selected.  A freeform text input will not be provided.Multiple-answer QuickSurveys survey.png
 * freeformTextLabel - The respondent is prompted to enter freeform text, in addition to an optional choice of answer.Freeform text in QuickSurveys.png
 * shuffleAnswersDisplay - The answers will be randomized and displayed in a different order for each respondent. This helps average out a response bias caused by the order of answers.  Defaults to true.
 * embedElementId - When this field is present, the survey can only be injected into a page with a DOM element matching the configured value by ID. For example, a survey with   will be displayed on a page with HTML , immediately after that element.QuickSurveys embedded survey.png

Adding message keys
Messages can be defined as part of an extension e.g. WikimediaMessages or by wiki page. For example the message "ext-quicksurveys-example-internal-survey-answer-positive" can be defined by editing the wiki page MediaWiki:ext-quicksurveys-example-internal-survey-answer-positive

For editing messages ensure you have the right permissions. You will need edit-interface right.

How to load a specific survey
You can bypass the sampling and load a survey using one of the methods below. Please note that the survey you want to load needs to be enabled and passed to the front end. See the "Notes and Gotchas" section if you are having trouble seeing a survey.
 * To load a random survey append  to the URL;
 * To load an internal survey whose name is 'internal example survey' append  to the URL;
 * To load an external survey whose name is 'external example survey' append  to the URL.

Note: The  parameter is not the literal survey name. It's the type and survey name. The leading  or   is stripped when looking up the survey name in the configuration. E.g.,  picks the survey named   not.

Rules for displaying a survey
Much of this logic seems to reside on the client.

mw.config.get( 'wgEnabledQuickSurveys' )

tells you what surveys are available.

Results
The initial impressions and responses are recorded in EventLogging. Initial impressions are in the QuickSurveyInitiation schema and responses are in QuickSurveysResponses. The  field in both schemas corresponds to the survey's configured.

Troubleshooting
For local development using Docker, to see quick surveys rendered on an article page, the page must exist locally when using Content Provider. Once the local page is created, appending the appropriate query parameters to the url will make the quick survey visible.

Notes and Gotchas

 * is provided by CentralNotice. To avoid setting up an extension run  in production and add   to your code.

Note that a survey won't show up when:


 * on the Main Page;
 * on non-article page;
 * on non-existent article page. Be careful when using the MobileFrontend content provider!;
 * on skin Minerva when the beta opt in panel is shown;
 * (Broken: if a survey is an external one and points to non-https location. TODO: Pending .)
