I am sending my HTML file to the client in node.js as shown below
app.get('/get', function(req, res) {
res.render(index.html);
});
Here, index.html refers to a json file. How can I send both together or refer the json file in the client?
HTTP only sends one resource at a time. If your page is requesting a JSON file, it needs to be served as a second request.
Alternatively, you can render HTML with a <script>
block that has a variable assignment with your JSON-encoded data as a value.
If you don't want to request the JSON file from the client as an independent HTTP request you can do one of the following:
Full server side rendering:
Use a template technology like moustache or handlebars , and try to render that data inline with the response. For example if you your JSON file returns a name and an address the index.html could look like:
<div>
<span>Name: {{name}} </span>
<address>Address: {{address}} </span>
<div>
Then when rendering you could pass a js object with properties name
and address
to the template and you wouldn't need to ask for the JSON file separately. This example follows moustache guidelines just in case I wasn't explicit enough.
Inline object
A bit like the previous solution but less elegant, you can add the full JSON response as an object with within a script tag, and then use it however you see fit. Try to append a block to he HEAD of index.html
like this:
<script>
var myObject = <contents of your JSON object>
</script>
The other possible solution was just described in another answer.
I hope this helps.
You can't send two types of files back in a single request, but you could either do an ajax call in the html to get the json you need:
<script type="text/javascript">
var json_data;
$.getJSON("URL_HERE", function(data) { json_data = data; });
</script>
or add the json to the html as a javascript object via a template engine (jade shown below):
script(type="text/javascript").
var json_data = #{ JSON.stringify(JSON_OBJECT_HERE) }
