這個插件是jsfmt，可以直接在package裏搜索到；

2.user setting裏放入如下配置:

{
    "autoformat": true,
    "extensions":
    [
        "js",
        "jsx",
        "sublime-settings"
    ],
    "options":
    {
        "jsx":
        {
            "alignWithFirstAttribute": true
 
,
            "attrsOnSameLineAsTag": false,
            "firstAttributeOnSameLine": false,
            "formatJSX": true,
            "maxAttrsOnTag": 1
        },
        "plugins":
        [
            "esformatter-jsx"
