如何将JS对象从服务器端传递到NodeJS中的客户端

Question

In PHP I used to pass objects from the backend to the front end in JSON form, using script tags.

<script>

var serversideStuff = '<?php echo json_encode($serversideArray); ?>';

</script>

How can I pass JS objects from the server-side to the clientside using nodeJS, express and Jade. There is probably a really good way that I'm just not aware of.

Hope you can help me out.

Answer 1

In PHP you use bad practices (dynamically generating javascript as part of an application).

With node you do it right. This means you

• Either write the data to the HTML (How would your website work without javascript, you are using progressive enhancement, right?)
• Expose that data as a web service you talk to over Ajax or WebSockets

Answer 2

<script type="text/javascript">
  var clientVar = {{JSON.stringify(serverVar)}}
</script>

change {{}} to whatever your template engine uses to interpret code
