Vuejs uses vue-markdown to render comment methods
If you want to use an editor or support markdown in the comment system. This package has quite a few advantages. For example, it supports emoji by default, which is perfect! The new version of laravist uses vue-markdown to render comments. This article mainly introduces examples of using markdown in Vuejs. The editor thinks it is quite good. Now I will share it with you and give you a reference. I hope it can help you.
Installation
Use npm directly to install:
npm install --save vue-markdown
It is also very simple to use
, It can be like this directly:
import VueMarkdown from 'vue-markdown'
new Vue({
components: {
VueMarkdown
}
})Or like this, a concrete example is: For example, we have a Comment.vue component used to render comments. You can directly specify it in this component:
import VueMarkdown from 'vue-markdown';
<template>
<p>
<vue-markdown :source="comment.body"></vue-markdown>
</p>
</template>
export default { // ... other codes
props:['comment'],
data(){
return {
comment : this.comment
}
},
components: {
VueMarkdown
},
// ... other codes
}Then when rendering:
<p class="comments"> <p class="comments" v-for="comment in comments"> <comment :comment="comment"> </comment> </p> </p>
Here we first pass in the entire comment through comment props (this comment is actually an object), and then pass it in to the veu-markdown component through :source in Comment.vue The content of the body field of each comment. Note that comment.body here saves the content of the comment in markdown format in the database.
Vuejs server-side rendering markdown example
const Koa = require('koa');
const _ = require('koa-route');
const vsr = require('vue-server-renderer');
const fs = require('fs');
const indexjs = require('./component/index.js');
const Vue = require('vue');
const MD = require('markdown-it')
const server = new Koa();
const route = {
index: (ctx, id) => {
// 解析markdown
const md = new MD().render(fs.readFileSync('./markdown/' + id + '.md', 'utf-8'));
// vue插入html代码
const app = new Vue({
data: {
main: md
},
template: `
<p>
<p class="main" v-html="main"></p>
</p>`
});
// 其他变量设置
const context = {
htmlTitle: id
};
// 加载模板html文件
const renderer = vsr.createRenderer({
template: fs.readFileSync('./template/index.template.html', 'utf-8')
});
// 渲染
renderer.renderToString(app, context, (err, html) => {
if (err) {
ctx.response.status = 500;
} else {
ctx.response.body = html;
}
})
}
};
server.use(_.get('/post/:id', route.index));
server.listen(8080);<!DOCTYPE html>
