URL-parameters and URL-hash

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:favourites,menu:community,menu:privacy,menu:advanced

theme-menu:intro,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:

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
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.
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
Use the navigator-language (if available)
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.
