前后端分离的项目，我们经常需要和 JSON 打交道，如果是在浏览器里面，我们可以使用控制台的输出直接格式化 JSON 数据，并且还可以任意的折叠展开每个节点，但是如果我们想把 JSON 直接在网页中格式化输出，我们就需要 vue-json-viewer 这样一款插件了。

vue-json-viewer 是一款，简单的 JSON 数据查看器组件，适用于 Vue.js 2.x.x 版本，并且支持动态增量更新组件数据。

安装

使用 npm:

$ npm install vue-json-viewer --save

使用 yarn:

$ yarn add vue-json-viewer

示例

<json-viewer :value="jsonData"></json-viewer>

<hr />

<json-viewer
  :value="jsonData"
  :expand-depth=5
  copyable
  boxed
  sort></json-viewer>

import Vue from 'vue'
import JsonViewer from 'vue-json-viewer'

// Import JsonViewer as a Vue.js plugin
Vue.use(JsonViewer)
// or 
// components: {JsonViewer}

new Vue({
  el: '#app',
  data() {
    return {
      jsonData: {
        total: 25,
        limit: 10,
        skip: 0,
        links: {
          previous: undefined,
          next: function () {},
        },
        data: [

            description: `Augusta Ada King, Countess of Lovelace (née Byron; 10 December 1815 – 27 November 1852) was an English mathematician and writer,
            chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer,
            the Analytical Engine. She was the first to recognise that the machine had applications beyond pure calculation,
            and published the first algorithm intended to be carried out by such a machine.
            As a result, she is sometimes regarded as the first to recognise the full potential of a "computing machine" and the first computer programmer.`,

            she was a pioneer of computer programming who invented one of the first compiler related tools.
            She popularized the idea of machine-independent programming languages, which led to the development of COBOL,
            an early high-level programming language still in use today.`,

添加 theme="my-awesome-json-theme" JsonViewer的组件属性
复制粘贴下面的模板并且根据自定义的theme名称做对应调整:

// values are default one from jv-light template
.my-awesome-json-theme {
  background: #fff;
  white-space: nowrap;
  color: #525252;
  font-size: 14px;
  font-family: Consolas, Menlo, Courier, monospace;

  .jv-ellipsis {
    color: #999;
    background-color: #eee;
    display: inline-block;
    line-height: 0.9;
    font-size: 0.9em;
    padding: 0px 4px 2px 4px;
    border-radius: 3px;
    vertical-align: 2px;
    cursor: pointer;
    user-select: none;
  }
  .jv-button { color: #49b3ff }
  .jv-key { color: #111111 }
  .jv-item {
    &.jv-array { color: #111111 }
    &.jv-boolean { color: #fc1e70 }
    &.jv-function { color: #067bca }
    &.jv-number { color: #fc1e70 }
    &.jv-object { color: #111111 }
    &.jv-undefined { color: #e08331 }
    &.jv-string {
      color: #42b983;
      word-break: break-word;
      white-space: normal;
    }
  }
  .jv-code {
    .jv-toggle {
      &:before {
        padding: 0px 2px;
        border-radius: 2px;
      }
      &:hover {
        &:before {
          background: #eee;
        }
      }
    }
  }
}
