It is better to use templating engine such as Mustache . 最好使用诸如Mustache之类的模板引擎。 For example: 例如：
Your txt file: 您的txt文件：
<html>
<head></head>
<body>
<p>{{abc}}</p>
</body>
</html>
And your code: 和你的代码：
const Mustache = require('mustache')
var abc = "Hi there"
var dat = fs.readFileSync('home.txt', 'utf8');
var html = Mustache.render(dat, {abc: abc});
fs.writeFile('index.html', html, (err) => {
if (err) throw err;
console.log('The file has been saved!');
});
