vue3+vite+ts使用monaco-editor编辑器的简单步骤
Best_卡卡 人气:0前言
近期要完成一个代码编辑器的内容,用的vue3.0+ts+vite架构,学习尚浅, 常在插件上遇坑
特此记录下在monaco-editor的使用
需求:yaml和sql的文件的高亮、补全
实现
1.安装
// ^0.34.1 yarn add monaco-editor
2.在vite.config.js中配置(如果不需要ts\js\html就不需要这么做)
// 强制预构建插件包 optimizeDeps: { include: [ `monaco-editor/esm/vs/language/json/json.worker`, `monaco-editor/esm/vs/language/css/css.worker`, `monaco-editor/esm/vs/language/html/html.worker`, `monaco-editor/esm/vs/language/typescript/ts.worker`, `monaco-editor/esm/vs/editor/editor.worker` ], },
3.组件封装与使用
monacoEditor.vue组件
<template> <div ref="codeEditBox" class="codeEditBox" :class="hightChange&&'codeEditBox1'" /> </template> <script lang="ts"> import { defineComponent, onBeforeUnmount, onMounted, ref, watch, } from 'vue' import JsonWorker from 'monaco-editor/esm/vs/language/json/json.worker?worker' import CssWorker from 'monaco-editor/esm/vs/language/css/css.worker?worker' import HtmlWorker from 'monaco-editor/esm/vs/language/html/html.worker?worker' import TsWorker from 'monaco-editor/esm/vs/language/typescript/ts.worker?worker' import EditorWorker from 'monaco-editor/esm/vs/editor/editor.worker?worker' import * as monaco from 'monaco-editor' import { language as sqlLanguage } from 'monaco-editor/esm/vs/basic-languages/sql/sql.js'; import { language as yamlLanguage } from 'monaco-editor/esm/vs/basic-languages/yaml/yaml.js'; import 'monaco-editor/esm/vs/basic-languages/sql/sql.contribution' import { editorProps } from './monacoEditorType' export default defineComponent({ name: 'MonacoEditor', props: editorProps, emits: ['update:modelValue', 'change', 'editor-mounted'], setup(props, { emit }) { (self as any).MonacoEnvironment = { getWorker(_: string, label: string) { if (label === 'json') { return new JsonWorker() } if (['css', 'scss', 'less'].includes(label)) { return new CssWorker() } if (['html', 'handlebars', 'razor'].includes(label)) { return new HtmlWorker() } if (['typescript', 'javascript'].includes(label)) { return new TsWorker() } return new EditorWorker() }, } let editor: any const codeEditBox = ref() const init = () => { monaco.languages.typescript.javascriptDefaults.setDiagnosticsOptions({ noSemanticValidation: true, noSyntaxValidation: false, }) monaco.languages.typescript.javascriptDefaults.setCompilerOptions({ target: monaco.languages.typescript.ScriptTarget.ES2020, allowNonTsExtensions: true, }) monaco.languages.registerCompletionItemProvider('sql', { provideCompletionItems() { const suggestions:any = []; // 这个keywords就是sql.js文件中有的 sqlLanguage.keywords.forEach((item:any) => { suggestions.push({ label: item, kind: monaco.languages.CompletionItemKind.Keyword, insertText: item, }); }) sqlLanguage.operators.forEach((item:any) => { suggestions.push({ label: item, kind: monaco.languages.CompletionItemKind.Operator, insertText: item, }); }) sqlLanguage.builtinFunctions.forEach((item:any) => { suggestions.push({ label: item, kind: monaco.languages.CompletionItemKind.Function, insertText: item, }); }) sqlLanguage.builtinVariables.forEach((item:any) => { suggestions.push({ label: item, kind: monaco.languages.CompletionItemKind.Variable, insertText: item, }); }) return { // 最后要返回一个数组 suggestions, }; }, }) monaco.languages.registerCompletionItemProvider('yaml', { provideCompletionItems() { const suggestions:any = []; // 这个keywords就是python.js文件中有的 yamlLanguage.keywords.forEach((item:any) => { suggestions.push({ label: item, kind: monaco.languages.CompletionItemKind.Keyword, insertText: item, }); }) return { // 最后要返回一个数组 suggestions, }; }, }) editor = monaco.editor.create(codeEditBox.value, { value: props.modelValue, language: props.language, readOnly: props.readOnly, theme: props.theme, ...props.options, }) // 监听值的变化 editor.onDidChangeModelContent(() => { const value = editor.getValue() // 给父组件实时返回最新文本 emit('update:modelValue', value) emit('change', value) }) emit('editor-mounted', editor) } watch( () => props.modelValue, (newValue) => { if (editor) { const value = editor.getValue() if (newValue !== value) { editor.setValue(newValue) } } }, ) watch( () => props.options, (newValue) => { editor.updateOptions(newValue) }, { deep: true }, ) watch( () => props.readOnly, () => { console.log('props.readOnly', props.readOnly) editor.updateOptions({ readOnly: props.readOnly }) }, { deep: true }, ) watch( () => props.language, (newValue) => { monaco.editor.setModelLanguage(editor.getModel()!, newValue) }, ) onBeforeUnmount(() => { editor.dispose() }) onMounted(() => { init() }) return { codeEditBox } }, }) </script> <style lang="scss" scoped> .codeEditBox { width: 100%; flex: 1; min-height: 100px; // height: 200px; overflow-y: auto; } .codeEditBox1{ height: calc(100% - 323px); } </style>
4.monacoEditorType.ts类型定义文件
import { PropType } from 'vue' export type Theme = 'vs' | 'hc-black' | 'vs-dark' export type FoldingStrategy = 'auto' | 'indentation' export type RenderLineHighlight = 'all' | 'line' | 'none' | 'gutter' export interface Options { automaticLayout: boolean // 自适应布局 foldingStrategy: FoldingStrategy // 折叠方式 auto | indentation renderLineHighlight: RenderLineHighlight // 行亮 selectOnLineNumbers: boolean // 显示行号 placeholder:string minimap: { // 关闭小地图 enabled: boolean } // readOnly: Boolean // 只读 fontSize: number // 字体大小 scrollBeyondLastLine: boolean // 取消代码后面一大段空白 overviewRulerBorder: boolean // 不要滚动条的边框 } export const editorProps = { modelValue: { type: String as PropType<string>, default: null, }, hightChange: { type: Boolean, default: false, }, width: { type: [String, Number] as PropType<string | number>, default: '100%', }, height: { type: [String, Number] as PropType<string | number>, default: '100%', }, language: { type: String as PropType<string>, default: 'javascript', }, readOnly: { type: Boolean, default: false, }, theme: { type: String as PropType<Theme>, validator(value: string): boolean { return ['vs', 'hc-black', 'vs-dark', 'hc-light'].includes(value) }, default: 'vs', }, options: { type: Object as PropType<Options>, default() { return { automaticLayout: true, // foldingStrategy: 'indentation', foldingStrategy: 'indentation', // 折叠方式 auto | indentation // renderLineHighlight: 'all', renderLineHighlight: 'all' || 'line' || 'none' || 'gutter', // 行亮 selectOnLineNumbers: true, // 显示行号 minimap: { // 关闭小地图 enabled: false, }, placeholder: 'ss', // readOnly: false, // 只读 fontSize: 16, // 字体大小 scrollBeyondLastLine: false, // 取消代码后面一大段空白 overviewRulerBorder: false, // 不要滚动条的边框 } }, }, }
5.在父组件中使用
<monacoEditor v-model="value" :language="language" :hight-change="hightChange" :read-only="tablist.length===0" width="100%" height="100%" @editor-mounted="editorMounted" /> import monacoEditor from './monacoEditor.vue' const value = ref('-- select * from infrastructure;') const language = ref('sql') const hightChange = ref<any>(false) const editorMounted = (editor: any) => { console.log('editor实例加载完成', editor) }
value:编辑器代码显示的值
language:要加载的语言类型
hightChange:改变编辑器的高度(可去掉,我这边有个sql查表的实现,需要在编辑区下面加一个sql查询的表格,所以需要这个参数)
read-only:编辑区是否是只读的,当左侧文件树为空时没有文件,编辑区不可写
editorMounted:加载完成操作
//记得在env.d.ts配置包的 declare module 'monaco-editor'; declare module 'monaco-editor/esm/vs/language/typescript/ts.worker?worker' declare module 'monaco-editor/esm/vs/basic-languages/sql/sql.js'; declare module 'monaco-editor/esm/vs/basic-languages/yaml/yaml.js'; declare module 'monaco-editor/esm/vs/language/json/json.worker?worker' declare module 'monaco-editor/esm/vs/language/css/css.worker?worker' declare module 'monaco-editor/esm/vs/language/html/html.worker?worker' declare module 'monaco-editor/esm/vs/editor/editor.worker?worker' declare module 'monaco-editor/esm/vs/basic-languages/javascript/javascript.js'
打包报错的处理
yarn build 时会发生下述报错
我在这里看到了解决办法https://github.com/microsoft/monaco-editor/blob/main/docs/integrate-esm.md
在monacoEditor.vue组件,重写getWorker方法
<template> <div ref="codeEditBox" class="codeEditBox" :class="hightChange&&'codeEditBox1'" /> </template> <script lang="ts"> import { defineComponent, onBeforeUnmount, onMounted, ref, watch, } from 'vue' // 减去以下包 -- import JsonWorker from 'monaco-editor/esm/vs/language/json/json.worker?worker' -- import CssWorker from 'monaco-editor/esm/vs/language/css/css.worker?worker' -- import HtmlWorker from 'monaco-editor/esm/vs/language/html/html.worker?worker' -- import TsWorker from 'monaco-editor/esm/vs/language/typescript/ts.worker?worker' -- import EditorWorker from 'monaco-editor/esm/vs/editor/editor.worker?worker' import * as monaco from 'monaco-editor' import { language as sqlLanguage } from 'monaco-editor/esm/vs/basic-languages/sql/sql.js';
