接着输入vue

vs code自动生成vue.json文件

{
    // Place your 全局 snippets here. Each snippet is defined under a snippet name and has a scope, prefix, body and 
    // description. Add comma separated ids of the languages where the snippet is applicable in the scope field. If scope 
    // is left empty or omitted, the snippet gets applied to all languages. The prefix is what is 
    // used to trigger the snippet and the body will be expanded and inserted. Possible variables are: 
    // $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders. 
    // Placeholders with the same ids are connected.
    // Example:
    "Print to console": {
        "scope": "vue,javascript,typescript",
        "prefix": "vue3.2",
        "body": [
            "<script setup lang='ts'>",
            "</script>",
            "<template>",
            "</template>",
            "<style>",
            "</style>",
        ],
        "description": "Log output to console"
    }
}
