There's a Visual Studio plugin available, and I know VS Code has a nice plugin as well ( you need to install certain tools yourself in that case ), as well as other editors with their own feature set. There is also Dub[0] which is a build tool for D and gives you access to all sorts of D packages. I'm still a beginner to D so forgive me if my answer doesn't suffice.
