A、安装

npm install ace-builds

B、在uniapp中使用

<template>
	<view class="content">
	   <div id="editor">ssss</div>
	   <button v-on:click="bb">格式</button>
	   <button v-on:click="aa">压缩</button>
	</view>
</template>

<script>
	 import ace from 'ace-builds/src-noconflict/ace';
   import 'ace-builds/src-noconflict/mode-javascript';
	 import 'ace-builds/src-noconflict/mode-golang';
	 import 'ace-builds/src-noconflict/mode-json';
	 import 'ace-builds/src-noconflict/mode-html';
    import 'ace-builds/src-noconflict/theme-monokai';
	 import 'ace-builds/src-noconflict/theme-dracula';
   import 'ace-builds/src-noconflict/ext-language_tools';
	 import 'ace-builds/src-noconflict/ext-beautify';
	export default {
		data() {
			return {
				title: 'Hello'
			}
		},
		  mounted() {
		    this.initEditor();
		  },
		onLoad() {

		},
		methods: {
			initEditor() {
				    const editor = ace.edit('editor'); // 初始化Ace Editor
             //editor.setTheme("ace/theme/dracula");
				    editor.setTheme("ace/theme/monokai");    //主题
					  editor.session.setMode("ace/mode/json"); //语言类型
				    //editor.session.setMode("ace/mode/golang");
				    //editor.session.setMode("ace/mode/javascript");
				    editor.setValue('{}'); // 设置初始代码值
			},
			bb(){
				const editor = ace.edit('editor'); // 初始化Ace Editor
				editor.session.setMode("ace/mode/json");
				var code =editor.getValue();				
				JSON.stringify(JSON.parse(code), null, 2)
				editor.setValue(JSON.stringify(JSON.parse(code), null, 2));
			},
			aa(){
				const editor = ace.edit('editor'); // 初始化Ace Editor
				editor.session.setMode("ace/mode/json");
				var code =editor.getValue();
				let ss = JSON.stringify(JSON.parse(code))
				editor.setValue(ss);
			}
		}
	}
</script>
<style>
  #editor { width: 100%; height: 700px; font-size: 14px;line-height: 20px;}
</style>

注意点：使用主题和模型一定要对应引用

如：使用editor.setTheme("ace/theme/dracula") 就需要引用 import '
ace-builds/src-noconflict/theme-dracula'
