Handlebars + Helpers Together

tests codecov npm version GitHub license npm

Handlebars + Handlebars-helpers (helpers are now maintained in this project) combined into a single package. Easily use in your nodejs as it is a drop in replacement when using handlebars directly.

We plan to make significant changes over time with this project such as the following:

Breaking Changes from v2 to v3

Because of the complexity in the legacy helpers library we have moved to exporting the libraries and a helper function to make it easier to use. Here are the exports:

Please see the examples below for how to use the library.

Table of Contents

Usage Nodejs

npm install @jaredwray/fumanchu --save

var {handlebars, helpers} = require('@jaredwray/fumanchu');
helpers({ handlebars: handlebars });
var template = handlebars.compile('{{#if (eq foo "bar")}}<p>Foo is bar</p>{{/if}}');
var html = template({foo: 'bar'});
console.log(html);

If using it with es6 you can access handlebars and helpers:

import {handlebars, helpers} from '@jaredwray/fumanchu';
helpers({ handlebars: handlebars });
const template = handlebars.compile('{{#if (eq foo "bar")}}<p>Foo is bar</p>{{/if}}');
const html = template({foo: 'bar'});
console.log(html);

If you want to just get an instance of handlebars via createHandlebars you can do the following (it is async):

import {createHandlebars} from '@jaredwray/fumanchu';
const handlebars = await createHandlebars(); //this will return a handlebars instance with all helpers
const template = handlebars.compile('{{#if (eq foo "bar")}}<p>Foo is bar</p>{{/if}}');
const html = template({foo: 'bar'});
console.log(html); // <p>Foo is bar</p>

It's just that easy! No need to add Handlebars to your project, it's already included.

Using Handlebars Helpers

If you only want to use handlebar helpers you can easily do that by doing the following:

var {helpers} = require('@jaredwray/fumanchu');
var handlebars = require('handlebars');
helpers({ handlebars: handlebars });
var fn = handlebars.compile('{{add value 5}}');
console.log(fn); // 10

If using it with es6 you can access helpers via destructuring:

import {helpers} from '@jaredwray/fumanchu';
import handlebars from 'handlebars';
helpers({ handlebars: handlebars });
const template = handlebars.compile('{{#if (eq foo "bar")}}<p>Foo is bar</p>{{/if}}');
const html = template({foo: 'bar'});
console.log(html); // <p>Foo is bar</p>

Helpers

More than 180 Handlebars helpers in ~20 categories. Helpers can be used with Assemble, Generate, Verb, Ghost, gulp-handlebars, grunt-handlebars, consolidate, or any node.js/Handlebars project.
