Parse array to http params Angular

Question

Hi I would like to parse array with strings/enumerates into http params in Angular.

My example http request:

http://localhost:8091/air-quality?cities=cityname1,cityname2,cityname3

Example arrays (I didnt realize this yet but I will probably use the 2nd option):

cities = ["london", "madrid", "paris"] or cities = [LONDON, MADRID, PARIS]

request:

this.httpClient.get<number>(this.url, {params: params});

At this moment I can just build long string but it will look pretty bad. I tried use stringify but this method added %5D at the begin and end of params.

You can use array join():

let params = cities.join(',');
