Debug node program with kate

Help
1

How do I write debug.json so that it will start the dap for node? I have the following configuration that does not work:


      node = {
        run = {
          request = "${pkgs.vscode-js-debug}/bin/js-debug";
          port = 9229;
        };
        configurations = {
          "Node (Launch)".request = {
            type = "pwa-node";
            request = "launch";
            program = ''''${file}'';
            args = ''''${args|list}'';
            cwd = ''''${workdir|dir}'';
            stopOnEntry = true;
            sourceMaps = true;
            protocol = "inspector";
            console = "integratedTerminal";
            enableDWARF = true;
            env = ''''${env|list}'';
          };
          "Node (Launch npm)".request = {
            type = "pwa-node";
            request = "launch";
            runtimeExecutable="npm";
            runtimeargs=["run""\${program}"];
            args = ''''${args|list}'';
            cwd = ''''${workdir|dir}'';
            stopOnEntry = true;
            sourceMaps = true;
            protocol = "inspector";
            console = "integratedTerminal";
            enableDWARF = true;
            env = ''''${env|list}, NODE_OPTIONS=--inspect-brk=9229''  ;
            port = 9229;
          };
          "Node (Attach)".request = {
            type = "server";
            request = "attach";
            processId = ''''${pid|int}'';
            stopOnEntry = true;
            sourceMaps = true;
            protocol = "inspector";
            console = "integratedTerminal";
          };
          "Deno (Launch)".request = {
            type = "pwa-node";
            request = "launch";
            program = ''''${file}'';
            args = ''''${args|list}'';
            cwd = ''''${workdir|dir}'';
            env = ''''${env|list}'';
            stopOnEntry = true;
            sourceMaps = true;
            protocol = "inspector";
            console = "integratedTerminal";
            enableDWARF = true;
            runtimeExecutable = "deno";
            runtimeArgs = [
              "run"
              ''--inspect-wait=localhost:9229''
              "-A"
            ];
          };
        };
      };

That doesn’t look like valid json to me. Perhaps I misunderstand something.

3

yeah it is nix language that eventually will be converted into the appropriate json note that:

‘‘$ become a literal $ as \$

“${pkgs.vscode-js-debug}/bin/js-debug” becomes the path to the js-debug executable

4

Can you paste the converted json? And can you tell me about the problems/issues you face when you try to use this configuration? It has long been on my list to get this particular debugger working
