Does VS code support starting a gulp-watch task on startup? I\'d like to start the watcher when I open the editor.
No, sorry. This is a good suggestion (ability to run a task on startup), can you please file an issue in the microsoft/vscode repo on GitHub? (Sorry, I can't post more than 2 links yet)?
In the meantime, here are a couple of options:
You can specify a particular task as a Build task and then press CMD+SHIFT+B when you open the folder to start the task. See here: https://code.visualstudio.com/docs/editor/tasks#_mapping-gulp-grunt-and-jake-output-to-problem-matchers
You could write an extension that is activated on startup and then runs gulp with the task name. See here for extension activation options: https://code.visualstudio.com/docs/extensionAPI/activation-events#_activationevents.
