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

class="codeEditBox"
:class="hightChange&&'codeEditBox1'"
/>
</template>
