Leaflet is a JavaScript library. Leaflet has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can install using 'npm i zv-leaflet' or download it from GitHub, npm.

Leaflet was created 11 years ago by Vladimir Agafonkin, an Ukrainian citizen living in Kyiv. Vladimir is no longer in Kyiv, because Russian bombs are falling over the city. His family, his friends, his neighbours, thousands and thousands of absolutely wonderful people, are either seeking refuge or fighting for their lives. The Russian occupation of Ukraine contravenes and violates several international laws, including the United Nations Charter. It is an unprovoked, unjustifiable, and despicable action that endangers countless civilians.

            First, this error message is indeed expected on Jan. 11th, 2022.
            See "Improving Git protocol security on GitHub".

            January 11, 2022 Final brownout.

            This is the full brownout period where we’ll temporarily stop accepting the deprecated key and signature types, ciphers, and MACs, and the unencrypted Git protocol.
            This will help clients discover any lingering use of older keys or old URLs.

            Second, check your package.json dependencies for any git:// URL, as in this example, fixed in this PR.

            As noted by JΓΆrg W Mittag:

            There was a 4-month warning.
            The entire Internet has been moving away from unauthenticated, unencrypted protocols for a decade, it's not like this is a huge surprise.

            Personally, I consider it less an "issue" and more "detecting unmaintained dependencies".

            Plus, this is still only the brownout period, so the protocol will only be disabled for a short period of time, allowing developers to discover the problem.

            The permanent shutdown is not until March 15th.

            Issue when several users are saving data in postgresql database with Rshiny (many duplicates of an unique row are created)
            Asked 2022-Mar-08 at 09:57

            I need some clarification on how to properly send queries to my database within RShiny...

            I have build-up an application in which anyone can create an account and then write some informations in a dataframe before saving those rows to my database.

            The app works perfectly well when testing my it with a single user but shows some issues when several users send data to my database at the same time. All the informations sends are duplicated 2 to 10 times in postgresql...

            For instance if I add an unique observation of 5 individuals of species "A" with an observation date on the 25th of february I will get 3 rows (sometimes it can be up to 10 duplicates) in my database instead of one. (like shown in the table below):

            Below please find a reproducible example using library(RSQLite) - just switch back to your postgres connection / schema.

            I don't think the issue is pool related. I guess (I can't verify without your DB) your call to rbind is problematic - as it sends multiple lines if the reactiveVal was used before.

            Furthermore, in a case like this it is much more efficient to create a cross-session reactive (here reactivePoll) to share the DB information among sessions, instead of having each session query the DB every second.

            How to create maps based on conditional panel in R with Shiny?
            Asked 2022-Feb-25 at 22:47

            I am trying to create several leaflet maps based on what the user select. I tried to produce a reproducible example. I have a sf with four shapes (i.e., representing four counties in NC). The user can choose to plot one to four maps based on the choice of the county (made through the "checkboxGroupInput". If the user select one county, I should plot one map representing the county the user selected. If the user selected two counties, two maps should be plotted, etc.

            I got several lines of code but I could not connect the user selection to my map. Below you can find what I tried to do. Thanks for any help.

            Interesting question. I would use a rather different approach to get the job done. Instead of creatign that many conditional panels, I would write a function that creates a collection of columns depending on the number of counties selected.

            Once you have populated your Leaflet GeoJSON Layer Group (typically with geojsonLayer.addData(geoJsonObject), then instead of adding that group to your map, simply add it into your MarkerClusterGroup:

            I tried using the leafletObject.invalidateSize() method but nothing changed.

            As has been commented, There seems to be an issue with flexdashboard in R 4.1. It does work (on MacOS) with R 3.6. I'd suggest filing an issue on their GitHub repo.

            Besides downgrading R, you could also "automatically" zoom in at the beginning and use flyTo() instead of setView().

            Both solutions are rather hot fixes but I am afraid that the core problem must be fixed by flexdashboard itself.
