muban-convert-hbs

Convert Handlebars templates to HTL, django, twig and others. It supports all of the commonly used features, and will add support for additional Handlebars Helpers to implement additional features that are popular in the target template language.

Handbelars templates are used in Muban to optimize frontend development for server-rendered HTML pages. This module is used to convert the development templates into server templates that can be used for the actual implementation, without having to do that manually.

Using this module doesn't guarantee 100% perfect target templates, so some manual checking is required to make sure the resulting templates are doing what is intended.

Installation

yarn add muban-convert-hbs

npm i -S muban-convert-hbs

Basic usage

import fs from 'fs';
import path from 'path';
import convert from 'muban-convert-hbs';
// var convert = require('muban-convert-hbs').default; // when using es5

const htl = convert(fs.readFileSync(path.resolve(__dirname, './foo.hbs'), 'utf-8'), 'htl');
const django = convert(fs.readFileSync(path.resolve(__dirname, './foo.hbs'), 'utf-8'), 'django');
const twig = convert(fs.readFileSync(path.resolve(__dirname, 'foo.hbs'), 'utf-8'), 'twig');
