Vue3+vite
没用过monaco-editord，照教程实践一下
效果：
- 安装依赖
pnpm install monaco-editor
- 在vite.config.js配置插件
export default defineConfig({
plugins: [
vue(),
......
...
],
......
...
// 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`
],
},
})
- codeEdit组件，文章原作者是ts，我是js项目，下面是把ts部分去掉的组件内容
<template>
<div ref="codeEditBox" class="codeEditBox"></div>
</template>
<script>
import { defineComponent, onBeforeUnmount, onMounted, ref, watch } from 'vue'
import jsonWorker from 'monaco-editor/esm/vs/language/json/json.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'
export default defineComponent({
name: 'monacoEditor',
props: {
// 绑定的值
modelValue: {
type: String,
default: null,
},
// 编辑器宽度
width: {
type: [String, Number],

},

}
},
},
},
emits: ['update:modelValue', 'change', 'editor-mounted'],
setup(props, { emit }) {
self.MonacoEnvironment = {
getWorker(_, label) {
if (label === 'json') {
return new jsonWorker()
}

},
}
let editor
const codeEditBox = ref()
const init = () => {
monaco.languages.typescript.javascriptDefaults.setDiagnosticsOptions({

noSyntaxValidation: false,
})
monaco.languages.typescript.javascriptDefaults.setCompilerOptions({

})
editor = monaco.editor.create(codeEditBox.value, {
value: props.modelValue,
language: props.language,
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.language,
newValue => {
monaco.editor.setModelLanguage(editor.getModel(), newValue)
}
)
onBeforeUnmount(() => {
editor.dispose()
})
onMounted(() => {
init()
})
return { codeEditBox }
},
})
</script>
<style lang="scss" scoped>
.codeEditBox {
width: v-bind(width);
height: v-bind(height);
}
</style>
- 使用方法
<codeEdit
v-model="text"
language="html"
width="100%"
height="700px"
@editor-mounted="editorMounted"
></codeEdit>
const text = ref('let a = 234')
const editorMounted = (editor) => {
console.log('editor实例加载完成', editor)
}
