Assemble is a powerful, extendable and easy to use static site generator for node.js. Used by thousands of projects for much more than building websites, Assemble is also used for creating themes, scaffolds, boilerplates, e-books, UI components, API documentation, blogs, gh-pages and more! Plugins for gulp and grunt are also supported.
We're happy to announce the release of Assemble v0.9.0! If you're new to assemble, the About section and FAQ might be a good place to start.

What is Assemble?
Assemble makes it easy to create, customize, generate and maintain complete web projects. Here are some highlights:
Install with npm:
$ npm i assemble --save
If you plan on using assemble's CLI, you'll need to use an assemblefile.js. Otherwise, assemble can be used like any other node.js library.
Example
Render a template with with handlebars:
var assemble = require('assemble');
var app = assemble();
var locals = {title: 'Home!'};
// add a "page"
app.page('home.hbs', {content: 'This is {{title}}'});
// render it!
app.render('home.hbs', locals, function(err, view) {
if (err) throw err;
console.log(view.content);
//=> 'This is Home!'
});
Create an assemblefile.js and add tasks to run:
var assemble = require('assemble');
var htmlmin = require('gulp-htmlmin');
var app = assemble();
app.page('a.hbs', {content: '...'});
app.page('b.hbs', {content: '...'});
app.page('c.hbs', {content: '...'});
app.task('default', function() {
return app.toStream('pages')
.pipe(app.renderFile())
.pipe(htmlmin())
.pipe(app.dest('site'));
});
// expose your instance of assemble
module.exports = app;
Use assemble via CLI or API
To run tasks, you can do one of the following:
assemble command.build methodCLI: Install Assemble globally
Install assemble using npm with the following command:
$ npm i -g assemble
With assemble installed, you may now run assemble from any project that has an assemblefile.js in its root (the "root" of a project is wherever package.json is).
API: Use the .build method
(This can be in any file, not just an assemblefile.js)
app.build('default', function(err) {
if (err) throw err;
console.log('done!');
});
Learn more about tasks.
Run assemble from the command line.
$ assemble <tasks> [options]
Note that for most command line options, order or definition makes no difference, so tasks can be defined before or after options.
Optionally specify one or more tasks to run. Multiple tasks are separated by a space.
Example
To run tasks foo and bar, you would enter the following in the command line:
$ assemble foo bar
Non-task commands and options are prefixed with -- and are specified using any of the following formats:
--foo, or--foo=bar. Also, key-value pairs may be separated by either = or a single whitespace, so --foo=bar and --foo=bar should both work.Additionally, as mentioned above, tasks may be defined before or after options, so both of the following are equivalent:
$ assemble --cwd foo bar
# or
$ assemble foo bar --cwd
Example
To emit views as they're loaded and log them to stderr, run assemble with the following command:
$ assemble --emit view
# or
$ assemble --emit=view
Object-paths may be specified using dot-notation for either the key or value in a command line argument.
Additionally, assemble uses expand-object (and some custom parsing) to make it easier to pass non-trivial options and commands via command line. So all of the following formats are possible.
Examples
Boolean values:
$ assemble --foo
# { foo: true }
Key-value pairs:
$ assemble --foo=bar
# { foo: 'bar' }
Nested booleans:
$ assemble --option=foo
# {options: { foo: true }}
Nested key-value pairs:
$ assemble --option=foo:bar
# {options: { foo: 'bar' }}
Deeply nested key-value pairs:
$ assemble --option=foo.bar.baz:qux
# {options: foo: { bar: { baz: 'qux' }}}}
Or on the left-side of the =:
$ assemble --option.foo.bar.baz=qux
# {options: foo: { bar: { baz: 'qux' }}}}
Change the cwd for the assemblefile.js to run, optionally specifying any tasks to run:
$ assemble <tasks> --cwd [directory]
Example
To run the scaffolds example in the examples/ directory, you would enter:
$ assemble --cwd examples/scaffolds
If successful, in the command line, you should see something like this:
The name of which file to load when running, defaulting to assemblefile.js:
$ assemble --file assemblefile.dev.js
Create an assemble app. This is the main function exported by the assemble module.
Params
options {Object}: Optionally pass default options to use.Example
var assemble = require('assemble');
var app = assemble();
Assemble has an extensive API for working with templates and template collections. In fact, the entire API from the templates library is available on Assemble.
While we work on getting the assemble docs updated with these methods you can visit the templates library to learn more about the full range of features and options.
Assemble offers the following low-level methods for working with the file system:
Assemble has first-class support for vinyl-fs, so any gulp plugin can be used in your assemble pipeline.
Create a vinyl stream. Takes glob patterns or filepaths to the source files to read.
Params
glob {String|Array}: Glob patterns or file paths to source files.options {Object}: Options or locals to merge into the context and/or pass to src pluginsExample
app.src('src/*.hbs');
// define `src` options
app.src('src/*.hbs', { layout: 'default' });
Specify a destination for processed files.
Params
dest {String|Function}: File path or rename function.options {Object}: Options and locals to pass to dest pluginsExample
app.dest('dist/');
Copy files with the given glob patterns to the specified dest.
Params
patterns {String|Array}: Glob patterns of files to copy.dest {String|Function}: Desination directory.returns {Stream}: Stream, to continue processing if necessary.Example
app.task('assets', function() {
// return, to let assemble know when the task has completed
return app.copy('assets/**', 'dist/');
});
Same as .src but takes glob patterns or filepaths for the symlinks to read.
Params
glob {String|Array}: Glob patterns or file pathsExample
app.symlink('src/*.hbs');
Assemble has the following methods for running tasks and controlling workflows:
Define a task to be run when the task is called.
Params
name {String}: Task namefn {Function}: function that is called when the task is run.Example
app.task('default', function() {
app.src('templates/*.hbs')
.pipe(app.dest('site/'));
});
Run one or more tasks.
Params
tasks {Array|String}: Task name or array of task names.cb {Function}: callback function that exposes errExample
app.build(['foo', 'bar'], function(err) {
if (err) throw err;
console.log('done!');
});
Watch files, run one or more tasks when a watched file changes.
Params
glob {String|Array}: Filepaths or glob patterns.tasks {Array}: Task(s) to watch.Example
app.task('watch', function() {
app.watch('docs/*.md', ['docs']);
});

If Assemble doesn't do what you need, please let us know
Is the assemble website up-to-date?
No, it's completely out-of-date. If you're using grunt-assemble, some of the documentation at assemble.io might still be useful. If you're using assemble v0.6.0 and higher, the documentation is probably wrong in almost every way.
We're actively (daily) working on a refactor and it's a very high priority.
What's the difference between assemble-core and assemble?
Assemble adds a CLI, a few built-in view collections: pages, layouts, and partials, middleware for parsing front-matter, and a few other basic defaults that we've found many users expect. If you'd prefer different defaults, assemble-core is a great starting point.
If you want something that handles templates, rendering, engines, helpers, collections, etc. but you don't need to run tasks or work with the file system, then consider using templates instead of assemble-core.
