garnet v0.1.9
Garnet
Garnet is a fast and minimalist template engine for Node.
Installation
$ npm install garnetFeatures
- Compatible with Express
- Performant due to precompilation and caching
- Evaluate JavaScript (e.g., for conditionals and loops):
<% code %> - Evaluate and embed (with sanitization):
<%= code %> - Evaluate and embed (without sanitization):
<%- code %> - Render a template from within a template:
<%- render(path, locals) %>
API
Compiling and rendering
To compile a template (or fetch an already-compiled template from cache):
var template = garnet.compile(path);To render a template:
var output = template(locals);To render a template from within another template (and compile it if necessary):
<%- render(path, locals) %>Default template directory
By default, Garnet looks in ./views for unqualified template names. If you want to change the default path to ./templates, for example, use:
garnet.templateDir = path.join(process.cwd(), 'templates');Default template extension
If you refer to a view without a file extension, Garnet assumes .garnet by default. You can change this like so:
garnet.templateExt = '.html';Caching
By default, Garnet will only load and compile a template once. If you want Garnet to reload and recompile templates whenever they are rendered, you can do so with:
garnet.enableCaching = false;This is useful for development (you don't need to restart the server for every change), but you should leave caching enabled in production.
Examples
Using Garnet with Express
To render a view with Express:
app.get('/', function(req, res) {
res.render('index.garnet');
}If you want to omit the .garnet extension from the line above, you can tell Express to assume it:
app.set('view engine', 'garnet');If you want to use a different file extension (e.g., .html) for views, use this:
app.set('view engine', 'html'); // Tell Express to assume this extension
app.engine('html', garnet.__express); // Tell Express to use Garnet for this extension
garnet.templateExt = '.html'; // Tell Garnet to assume this extensionLocals
You can pass data to a view using the locals argument.
For example, in app.js:
res.render('user.garnet', { name: 'Stephan Boyer' });In views/user.garnet:
Name: <%= locals.name %>Conditionals
<% if (user) { %>
Name: <%= user.name %>
<% } %>Loops
<% users.forEach(function(user) { %>
Name: <%= user.name %>
<% } %>Layouts
We simply pass the name of the view to the layout as a local:
<!DOCTYPE html>
<html>
<head>
<title>Layout Demo</title>
</head>
<body>
<%- render(locals.view, locals) %>
</body>
</html>In Express, you might render a view with this layout as follows:
app.get('/', function(req, res) {
res.render('layout.garnet', { view: 'index.garnet' });
