This document gives an overview of which URL-parameters can be used to influence MapComplete.


 What is a URL parameter?
--------------------------


"URL-parameters are extra parts of the URL used to set the state.

For example, if the url is `https://mapcomplete.org/cyclofix?lat=51.0&lon=4.3&z=5&test=true#node/1234`, the URL-parameters are stated in the part between the `?` and the `#`. There are multiple, all separated by `&`, namely:


  - The url-parameter `lat` is `51.0` in this instance
  - The url-parameter `lon` is `4.3` in this instance
  - The url-parameter `z` is `5` in this instance
  - The url-parameter `test` is `true` in this instance


Finally, the URL-hash is the part after the `#`. It is `node/1234` in this case.

The URL-hash can contain multiple values:


- The id of the currently selected object, e.g. `node/1234`

- The currently opened menu view

- The base64-encoded JSON-file specifying a custom theme (only when loading)


### Possible hashes to open a menu


The possible hashes are:


`menu:about`,`menu:settings`,`menu:community`,`menu:privacy`,`menu:advanced`

`theme-menu:intro`,`theme-menu:filters`,`theme-menu:download`,`theme-menu:copyright`,`theme-menu:share`


 language
----------

 The language to display MapComplete in.
The user display language is determined in the following order:

1. Use the language as set by the URL-parameter `language` (following ISO 639-1 | ex. `language=nl`). This will _disable_ setting the language by the user
2. If the user did log in and did set their language before with MapComplete, use this language. This language selection is synchronized accross devices using the openstreetmap.org user preferences.
3. If the user visited MapComplete before and did change their language manually, this changed language will be saved in local storage. Use the language from local storage
4. Use the navigator-language (if available)
5. Use English

Note that this URL-parameter is not added to the URL-bar by default.
Note that the _loading_ screen will always use the navigator language.

Translations are never complete. If a translation in a certain language is missing, English is used as fallback.

This documentation is defined in the source code at [Locale.ts](/src/UI/i18n/Locale.ts#L35)

 No default value set
