If you want to use handlebars, just grab the npm module:
npm install handlebars
Then in your script, you can use handlebars to render your output based on a simple template that iterates over the array foo
and creates a <p>
for each item, containing the text of the bar
property:
var handlebars = require('handlebars');
// get your data into a variable
var fooJson = require('foo.json');
// set up your handlebars template
var source = '{{#each foo}}<p>{{this.bar}}</p>{{/each}}';
// compile the template
var template = handlebars.compile(source);
// call template as a function, passing in your data as the context
var outputString = template(fooJson);
If you want to use a .hbs template file instead of a string source
you can use the fs
module to read the file with fs.readFile
, call toString()
on the returned buffer, and use that to call a rendering function. Try this:
var handlebars = require('handlebars');
var fs = require('fs');
// get your data into a variable
var fooJson = require('path/to/foo.json');
// read the file and use the callback to render
fs.readFile('path/to/source.hbs', function(err, data){
if (!err) {
// make the buffer into a string
var source = data.toString();
// call the render function
renderToString(source, fooJson);
} else {
// handle file read error
}
});
// this will be called after the file is read
function renderToString(source, data) {
var template = handlebars.compile(source);
var outputString = template(data);
return outputString;
}
