I am able to run deno from command line (deno vs ts-node : what's the difference). I would like to run it from VS code. I also tried to compile it first (by deno run) and run from vs code on result. I made repo to show how to run it, but it runs two times, first time to compile source, second to run in vscode on compiled source. I would like to just run deno from vs code directly or compile ts file with deno before run them.
To compile TS files first without running the code, you could try deno fetch <filename>. This command downloads all the remote dependencies, compiling the code, but not evaluating the code.
Not clear what does "run deno from VSCode directly" mean, but you might visit vscode-deno and file a feature request.
