swig-package-tmpl-loader

Swig template loader

Allow you to reference npm://<package name>/filepath in your Swig template's include and import tags.

It extends swig default loader: swig.loaders.fs Swig builtin loaders

e.g.

{% import "npm://package-a/spec/template-3.html" as foo %}

{% include "npm://@scope-name/package-b/views/template-2.html" %}

{{foo.doSomething()}}

It uses require.resolve() to locate and cache package path by its name, replace npm://... with exact package path when swig loads your template

npm install swig-package-tmpl-loader

var swig = require('swig');
var templateLoader = require('swig-package-tmpl-loader');
templateLoader.swigSetup(swig); // Calls swig.setDefaults({loader: templateLoader.createLoader()});

swig.renderFile('sampleFile', {locals: {}});

Now you can split your template files to different Node modules , publish and share them with fellows.

Injection

When Working with require-injector, it supports package Name and package path injection, like IoC container does.

var rj = require('require-injector');
var tmploader = require('swig-package-tmpl-loader');
// Setup injector
var injector = rj();
injector.fromDir(process.cwd())
	.substitute('oldPackage', 'newPackage');
// Or
injector.fromDir(process.cwd())
	.swigTemplateDir('oldPackage', 'node_modules/newPackage');

// Setup Swig
tmploader.swigSetup(swig, {injector: injector});
var out = swig.renderFile('./template.html'), {locals: {}});

While in template.html

{% include "npm://oldPackage/includedTemplate.html" %}

Will actually work as {% include "npm://newPackage/includedTemplate.html" %}

API

1. swigSetup(swig, opts)

It calls swig.setDefaults({loader: templateLoader.createLoader()})
Parameters:

• swig
  Instance of require('swig')
• opts.memoize, True if use _.memoize() to cache require.resolve's result, default is true.
• opts.prefix, default is npm://
• opts.injector require-injector

2. createLoader(swig, basepath, encoding, opts)

create file system loader.
Parameter is same as what swig.loaders.fs has, except:

• swig

• opts.memoize, True if use _.memoize() to cache require.resolve's result, default is true.
