Template helper for parsing YAML from a string.
Install with npm
npm i helper-yaml --save
var yaml = require('helper-yaml');
Usage with [handlebars]
var handlebars = require('handlebars');
handlebars.registerHelper('yaml', yaml.sync);
handlebars.compile('{{{yaml "name: Halle\nage: 4\n"}}}')();
//=> {first: 'Halle', age: 4}
Usage with Template
var yaml = require('helper-yaml');
var Template = require('template');
var template = new Template();
/**
* Register an engine
*/
template.engine('foo', require('engine-handlebars'));
/**
* Register the helper
*/
template.asyncHelper('yaml', yaml);
template.helper('stringify', function (o) {
return JSON.stringify(o);
});
/**
* Add some templates
*/
// note that JSON.stringify and JSON.parse are only
// necessary here since I'm defining the YAML string inline.
// If it's passed as a variable JSON.parse/stringify aren't needed
template.page('abc.foo', '{{{stringify (yaml "first: Halle\nlast: Schlinkert\n")}}}');
template.page('xyz.foo', '{{{stringify (yaml "first: Brooke\nlast: Schlinkert\n")}}}');
/**
* Render the templates
*/
template.render('abc.foo', function (err, res) {
if (err) console.log(err);
console.log(JSON.parse(res));
//=> { first: 'Halle', last: 'Schlinkert' }
});
template.render('xyz.foo', function (err, res) {
if (err) console.log(err);
console.log(JSON.parse(res));
//=> { first: 'Brooke', last: 'Schlinkert' }
});
