More comprehensive consolidate-style engine support for nunjucks. Should work with express, assemble, verb, generate, update, and any other app that follows consolidate conventions.

Install

Install with npm:

$ npm install --save engine-nunjucks

Usage

var engine = require('engine-nunjucks');

API

Initialize Nunjucks with the given options and default settings from engine-nunjucks.

Params

  • options {String}

Example

engine.configure([options]);

Add a global value that will be available to all templates. Note: this will overwrite any existing global called name. Returns env (the nunjucks instance) for further method chaining.

Params

  • name {String}
  • returns {any} value

Example

engine.addGlobal(name, value);

Add a custom nunjucks extension. Also called "tags". This exposes the parser API and allows you to do anything you want with the template.

Params

  • name {String}: The name of the extension to add
  • returns {Function} fn: function

Example

env.addExtension(name, fn);

Asynchronously compile the given string, with the given options and callback. If no callback is passed, .compileSync is called with the given arguments.

Params

  • str {Object}: The string to compile
  • options {Object|Function}: Options object to pass to nunjucks or callback function
  • cb {Function}: Callback function
  • returns {undefined}

Example

engine.compile('foo  bar', function(err, fn) {
  console.log(fn({title: 'AAA'})); //=> 'foo AAA bar'
  console.log(fn({title: 'BBB'})); //=> 'foo BBB bar'
  console.log(fn({title: 'CCC'})); //=> 'foo CCC bar'
});

Synchronously compile the given string with options.

Params

  • str {Object}: The string to compile
  • options {Object}: Options object to pass to nunjucks
  • returns {Function}: returns the compiled function

Example

var fn = engine.compileSync('foo  bar');
console.log(fn({title: 'AAA'})); //=> 'foo AAA bar'
console.log(fn({title: 'BBB'})); //=> 'foo BBB bar'
console.log(fn({title: 'CCC'})); //=> 'foo CCC bar'

Asynchronously render the given template string with locals and callback.

Params

  • str {String}
  • options {Object|Function}: or callback function
  • callback {Function}

Example

var locals = {name: 'engine-nunjucks'};
engine.render('abc engine-nunjucks xyz', locals, function(err, html) {
 console.log(html);
 //=> '[foo:bar]'
})

Asynchronously or synchronously render the given str with locals and optional callback.

Params

  • str {Object|Function}: The string to render or compiled function.
  • locals {Object}
  • returns {String}: Rendered string.

Example

var engine = require('engine-nunjucks');
engine.renderString('engine-nunjucks', {name: 'engine-nunjucks'}, function(err, str) {
  console.log(str);
  //=> 'engine-nunjucks'
});
// or
var str = engine.renderString('engine-nunjucks', {name: 'engine-nunjucks'});
console.log(str);
//=> 'engine-nunjucks'

Synchronously render the given str (or compiled function) with locals.

Params

  • str {String|Function}: The string to render or compiled function.
  • locals {Object}
  • returns {String}: Rendered string.

Example

var engine = require('engine-nunjucks');
engine.renderSync('engine-nunjucks', {name: 'engine-nunjucks'});
//=> 'engine-nunjucks'

Render the contents of the file at the given filepath, with locals and optional callback.

Params

  • filepath {String}
  • options {Object|Function}: or callback function
  • cb {Function}

Register custom filter name with the given fn. nunjucks filters are technically similar to handlebars helpers, but they're used differently in templates. This method is also aliased as .filter.

Params

  • name {String}: Filter name
  • fn {Function}: Filter function.

Example

engine.addFilter('foo', function(str) {
  // do stuff to `str`
  return str;
});

Register multiple template filters. Also aliased as .filters.

Params

  • filters {Object|Array}: Object, array of objects, or glob patterns.

Example

engine.addFilters({
  foo: function() {},
  bar: function() {},
  baz: function() {}
});

Register an async filter function. Also aliased as .asyncFilter.

Params

  • name {String}: Filter name.
  • fn {Function}: Filter function

Example

engine.addAsyncFilter('upper', function(str, next) {
  next(null, str.toUpperCase());
});

Register multiple async template filters. Also aliased as .asyncFilters.

Params

  • filters {Object|Array}: Object, array of objects, or glob patterns.

Example

engine.addAsyncFilters({
  foo: function() {},
  bar: function() {},
  baz: function() {}
});

Get a previously registered filter.

Params

  • name {String}: Filter name
  • returns {Function}: Returns the registered filter function.

Example

var fn = engine.getFilter('foo');

Get a previously registered async filter.

Params

  • name {String}: Filter name
  • returns {Function}: Returns the registered filter function.

Example

var fn = engine.getAsyncFilter('foo');

Default options

These are the actual default options used. These can be overridden with custom values on any of the methods.

var defaults = {
  ext: '.html',
  name: 'nunjucks',
  base: 'templates',
  throwOnUndefined: true,
  autoescape: false,
  watch: false
};
