Re: Request for feedback: Alternate desktop runtime architecture

I had a look — running it on Safari/OSX/High Sierra.

it started fast and seemed responsive.

I couldn’t get it to start a SQL query session to put in some query to see how that went, bu I did click on a bunch of other things and it seemed very responsive.. which is what you want to know.

I was able to put the URL into another tab and have two copies running. that was easy enough.

Without a bunch of hoopla, I couldn’t get it to run in firefox or chrome to see how that might run.

and it seems like it needs to be started from the app — as I couldn’t just stick the URL into second browser.

the end goal — is use the browser.

I”m not sure if that means I’ll be able to bookmark the URL and then just use it locally. if so… that might be nice.

and getting a SQL session in another browser applicaiton .. that would be good too.

just my thoughts.

Like some other similar applications, a server process is launched and lives in the system tray, from where it can be shutdown at any time, or new windows opened. When it is first started, it will launch a browser window to render pgAdmin automatically. If additional instances are launched, the previously running instance will be re-used to avoid wasting resources.
