QUESTION
I have a pipeline set up for my Bitbucket repository that runs npm install
if there is no node
cache. Up until now it has worked fine, but the node
cache was recently cleared, and now I'm getting the following output from Bitbucket (Pastebin link, due to character limit): https://pastebin.com/fY9TznNn

Answered 2021-May-05 at 12:45Looks like my intuition was right—it was because of the node-sass
package. Apparently it's deprecated. Installing sass
instead fixed the problem!
QUESTION
I am bringing up aws_ecs_task_defintion
with following terraform configuration.
I pass local.image_tag
as variable to control the deployment of our ecr image through terraform.
I am able to bring up the ecs_cluster on initial terraform plan/apply cycle just fine.
However, on the subsequent terraform plan/apply cycle, terraform is forcing the new container definition and thats why redeploying the entire task definition even though our ecr image local.image_tag
remains just same
This behaviour, is causing the unintended task definition recycle without any changes to the ecr image and just terraform forcing values with defaults.
TF Config
...ANSWER
Answered 2021-Apr-16 at 15:41There is a known terraform aws provider bug for this issue.
In order to make terraform not replace the running task / container definition, I have to fill out all the default values that its showing on terraform plan with either null or empty sets of configuration.
Once all the parameters are filled out, I ran the terafform plan/apply cycle again to ensure its not replacing the container definition like it was doing it before.

After figuring out how to deal with TypeScript and use-supercluster library I have "made it work" until I got a new problem: I get an empty array whenever I use useSuperCluster()
function.
I am following the creator's guide so I can handle my own project.
This is what I do:

QUESTION
I am having troubles while implementing use-supercluster with TypeScript. I am trying to use clusters to differentiate two types of data in a Google Map with something like red clusters vs. green clusters.
I can't find any documentation related to use this library with TypeScript and I am not getting enough information from its types:
So, what is argument P
? I was following the use-supercluster
creator's guide to add clusters but after installing supercluster
types I am getting errors here:
ANSWER
Answered 2021-Feb-01 at 21:27Well... I found this file on the library's repo on Github and it explains pretty straightforward how to use useSuperCluster()
on TypeScript.
Answering to my own question, it seems that points
is in fact declared as an array of PointFeature
where JsonProperties
comes from geojson library.

QUESTION
I am trying to use marker clustering because I have over 2000 markers being mapped currently, but I am not sure how to implement it with the way that I am loading the markers. Do I have to use a GeoJSON in order to use marker clustering? I would prefer to not use GeoJSON if possible, I am using a JSON file at the moment and looping through the data stored on Firebase. I would like to use the supercluster library if possible (https://github.com/mapbox/supercluster) but I am not sure what to load into index.load(points). Is clustering possible the way I have my code at the moment?
...ANSWER
Answered 2019-Dec-08 at 23:00The easiest way to do clustering in Mapbox-GL-JS is using a GeoJSON source with cluster: true
as in this example. It doesn't matter that your data is being sent to the browser as some other format, you can convert it into GeoJSON easily and then add it.
Currently you are representing your points using Markers, rather than a layer within the map such as circle
or symbol
. That would be more complex to combine with clustering, as you would need to create and destroy markers on demand, as the user zooms in and out. It will be much simpler to manage with a map layer, although it will limit your ability to style the marker symbols.

As I understand this is related to android support library version mismatch, so i have forced using same library version . However, the problem has persisted. Here is the root level build.gradle:

attribute was added in API Level 28.
Set your compileSdkVersion
to 28 or higher to be able to use libraries that reference this attribute.
QUESTION
I have some rows with geo points in an ElasticSearch index. Now, I search for all rows e.g. in the radius of 5 kilometers. The result is a list with all points matching the query. Is it possible to cluster the result in ElasticSearch to get all "hotspots"? Already found the geo centroid aggregation function of elasticsearch but thats not the thing Iam searching for. I know, it is possible to do it with libraries like Supercluster by Mapbox or something like that. But is it possible with ElasticSearch? please see the two pictures. The second picture shows the result I want to get. Cheers!
...ANSWER
Answered 2019-Nov-06 at 07:49I haven't used it but i think you need a geo hash grid aggregation. See: https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-geohashgrid-aggregation.html
You should be able to vary your precision and it will return geo_hash buckets with counts of docs.
QUESTION
I'm making a clustered map with mapbox supercluster. The problem I face is that clusters are not at the correct location. For example I only have dogs in the netherlands
but when zoomed out they are in france aswel.
When I zoom further the clusters slowly move al to the Netherlands. When I am scrolling the clusters move on the map aswel.
The problem can be seen here on my site https://v2.sayhi.dog/?dog-map=true.
My code looks like this (I use vue.js):

Answered 2019-Sep-02 at 16:02This link here says you need an offset for your markers so they can stay centerd all the time, and going through your code quickly i think you need it here
