VScode配置vue2用户代码片段

介绍

如题，使用VScode新建一个文件的时候，比如 vue 文件，我们需要手动输入以下内容：

<template>
  <div>

  </div>
</template>

<script>
export default {
    name: "component_name",
    data() {
        return {

        }
    },
    created() {

    },

    mounted() {

    },

    methods() {

    },

    destroyed() {

    }
}
</script>

<style scoped>

</style>

每次新建都需要这么做，显得很麻烦，所以，我们需要配置一个模板

配置步骤

点击顶部菜单，文件-首选项-用户代码片段， 选择新建全局代码片段文件，随便输入一个文件名，比如vue

文件默认内容如下：

{
    // Place your global 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": "javascript,typescript",
    //  "prefix": "log",
    //  "body": [
    //      "console.log('$1');",
    //      "$2"
    //  ],
    //  "description": "Log output to console"
    // }
}

格式说明

配置文件需要三部分，prefix就是触发此模板文件的命令，body是模板内容，description就是描述信息

配置内容

以 vue 文件为例，配置模板内容如下：

{
    "Create vue template": {
        "prefix": "vue2",
        "body": [
            "<template>",
            "  <div>\n$0",
            "  </div>",
            "</template>\n",
            "<script>",
            "export default {",
            "    name: \"${1:component_name}\",",
            "    data() {",
            "        return {\n",
            "        }",
            "    },",
            "    created() {\n",
            "    },\n",
            "    mounted() {\n",
            "    },\n",
            "    methods() {\n",
            "    },\n",
            "    destroyed() {\n",
            "    }",
            "}",
            "</script>\n",
            "<style scoped>\n",
            "</style>"
        ],
        "description": "default vue template"
    }
}

注意：模板里不能使用tab制表符，否则会报错

此时，新建一个 vue 文件，输入vue2，按回车，会自动创建模板

其他格式代码参考 vue 语法即可
