nunjucks-hapi's Introduction

nunjucks-hapi

A simple wrapper to let you use Nunjucks as a Hapi templating engine.

Usage

The following example will let you use Nunjucks templates, including template inheritance, inside Hapi. This assumes:

your templates are in a directory called "views"
they have the extension "html"
you have a template file in there called "mytemplate"

var Hapi = require('hapi')
var Path = require('path')
var NunjucksHap = require('nunjucks-hapi')

var server = new Hapi.Server()
server.connection({port:5000,host:'localhost'})

// set up templates
server.views({
  engines: {
    html: NunjucksHapi
  },
  path: Path.join(__dirname, 'views')
})

// Add a route
server.route({
  method: 'GET',
  path: '/test',
  handler: function (request, reply) {
    reply.view('mytemplate',{
      'myvariable': 'myvalue'
    })
  }
})

// start server
server.start()

Using Nunjucks filters and environments

If you want to go beyond the default configuration of Nunjucks, you need to configure an environment. Once that's done, you can do anything to the environment, like add filters or custom tags via extensions. This works just like the Nunjucks documentation says it does, with the exception that the path to templates is now required.

The example is otherwise the same as the above

var NunjucksHapi = require('nunjucks-hapi');

// set a common view path
var viewPath = Path.join(__dirname, 'views')

var env = NunjucksHapi.configure(viewPath)

// do anything you want to the env here
env.addFilter('somefilter', function(str, count) {
  // return some string
})

// set up templates with the same view path
server.views({
  engines: {
    html: NunjucksHapi
  },
  path: viewPath
})
