Add side button in Brackets extension

Question

I'm developing Brackets extension and want to add side button. What module can do that?

Answer 1

Short answer: There is no module or API for it, you have to do it yourself.

Helpful answer: You can use this snipped to add a Button to the toolbar:

$toolbarButton = $(document.createElement("a"))
    .attr("id", "phanect-extensionname-toolbar-icon")
    .attr("href", "#")
    .attr("title", Strings.TOOLBAR_ICON_TOOLTIP)
    .on("click", function () {
        // Handle click
    })
    .appendTo($("#main-toolbar .buttons"));

For the icon of the Button and the css see Extension Icon Guidelines
