如何让Express输出格式正确的HTML? [英] How can I get Express to output nicely formatted HTML?

问题描述

使用Express for Node.js时，我注意到它输出的HTML代码没有换行符或制表符.尽管下载可能更有效，但在开发过程中可读性不强.

When using Express for Node.js, I noticed that it outputs the HTML code without any newline characters or tabs. Though it may be more efficient to download, it's not very readable during development.

推荐答案

在主app.js中或它所在的位置:

In your main app.js or what is in it's place:

Express 4.x

if (app.get('env') === 'development') {
  app.locals.pretty = true;
}

Express 3.x

app.configure('development', function(){
  app.use(express.errorHandler());
  app.locals.pretty = true;
});

Express 2.x

app.configure('development', function(){
  app.use(express.errorHandler());
  app.set('view options', { pretty: true });
});

我在development中放了漂亮的印刷品，因为您希望使用production中的丑陋"来提高效率.在生产中进行部署时，请确保设置环境变量NODE_ENV=production.这可以通过在package.json的脚本"字段中使用并执行以启动的sh脚本来完成.

I put the pretty print in development because you'll want more efficiency with the 'ugly' in production. Make sure to set environment variable NODE_ENV=production when you're deploying in production. This can be done with an sh script you use in the 'script' field of package.json and executed to start.

Express 3 已更改因为:

Express 3 changed this because:

不再需要视图选项"设置，app.locals是与res.render()合并的局部变量，因此[app.locals.pretty = true与传递res.render(view ，{pretty:true}).

The "view options" setting is no longer necessary, app.locals are the local variables merged with res.render()'s, so [app.locals.pretty = true is the same as passing res.render(view, { pretty: true }).
