assemble-core
Built on top of base and templates, assemble-core is used in assemble to provide the baseline features and API necessary for rendering templates, working with the file system, and running tasks.
Implementors and hackers can use assemble-core to create rich and powerful build tooling, project scaffolding systems, documentation generators, or even your completely custom static site generators.

Install
NPM
Install
Install with npm:
$ npm install --save assemble-core
yarn
Install with yarn:
$ yarn add assemble-core && yarn upgrade
Usage
var assemble = require('assemble-core');
var app = assemble();
Examples
view collections
Create a custom view collection:
var app = assemble();
app.create('pages');
Now you can add pages with app.page()
or app.pages()
:
app.page('home.hbs', {content: 'this is the home page!'});
render
Render a view:
var app = assemble();
var view = app.view('foo', {content: 'Hi, my name is <%= name %>'});
app.render(view, { name: 'Brian' }, function(err, res) {
console.log(res.content);
//=> 'Hi, my name is Brian'
});
Render a view from a collection:
var app = assemble();
app.create('pages');
app.page('foo', {content: 'Hi, my name is <%= name %>'})
.set('data.name', 'Brian')
.render(function (err, res) {
console.log(res.content);
//=> 'Hi, my name is Brian'
});
API
Assemble
Create an assemble
application. 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();
File System API
Assemble has the following methods for working with the file system:
Assemble v0.6.0 has full vinyl-fs support, so any gulp plugin should work with assemble.
.src
Use one or more glob patterns or filepaths to specify source files.
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 tosrc
plugins
Example
app.src('src/*.hbs', {layout: 'default'});
.dest
Specify the destination to use for processed files.
Params
dest
{String|Function}: File path or custom renaming function.options
{Object}: Options and locals to pass todest
plugins
Example
app.dest('dist/');
.copy
Copy files from A to B, where A
is any pattern that would be valid in app.src and B
is the destination directory.
Params
patterns
{String|Array}: One or more file paths or glob patterns for the source files to copy.dest
{String|Function}: Desination directory.returns
{Stream}: The stream is returned, so you can continue processing files if necessary.
Example
app.copy('assets/**', 'dist/');
.symlink
Glob patterns or paths for symlinks.
Params
glob
{String|Array}
Example
app.symlink('src/**');
Task API
Assemble has the following methods for running tasks and controlling workflows:
.task
Define a task. Tasks are functions that are stored on a tasks
object, allowing them to be called later by the build method. (the CLI calls build to run tasks)
Params
name
{String}: Task namefn
{Function}: function that is called when the task is run.
Example
app.task('default', function() {
return app.src('templates/*.hbs')
.pipe(app.dest('dist/'));
});
.build
Run one or more tasks.
Params
tasks
{Array|String}: Task name or array of task names.cb
{Function}: callback function that exposeserr
Example
app.build(['foo', 'bar'], function(err) {
if (err) console.error('ERROR:', err);
});
.watch
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']);
});
FAQ
How does assemble-core differ from assemble?
| feature | assemble-core | assemble | notes |
| --- | :---: | :---: | --- |
| front-matter parsing | No | Yes | use assemble or use parser-front-matter as an .onLoad
middleware. |
| CLI | No | Yes | Create your own CLI experience, or use assemble |
| Built-in template collections | No | Yes | Use .create()
to add collections |
| Built-in template engine | No | Yes | assemble ships with engine-handlebars. Use .engine()
to register any consolidate-compatible template engine. |
Toolkit suite
assemble-core is a standalone application that was created using applications and plugins from the toolkit suite:
Building blocks
- base: framework for rapidly creating high quality node.js applications, using plugins like building blocks.
- templates: used to create the foundation of assemble-core's API, along with support for managing template collections, template engines and template rendering support
Plugins
- assemble-fs: adds support for using gulp plugins and working with the file system
- assemble-streams: adds support for pushing views and view collections into a vinyl stream
- base-task: adds flow control methods

Heads up!
Please let us know if any of the following heading links are broken. Thanks!
0.31.0 - 2017-11-2011
dependencies
- Bumps assemble-streams to ensure that
view
is decorated with.toStream()
when created by app (instead of a collection). This is arguably a bugfix, but it might break someone's code.
0.30.0 - 2017-08-01
dependencies
- Bumps assemble-fs and assemble-render-file to get updates that merge the dest path information onto the context so that it can be used to calculate relative paths for navigation, pagination, etc.
0.29.0 - 2017-02-01
dependencies
- Bumps assemble-fs to v0.9.0 to take advantage of improvements to
.dest()
handling.
0.28.0 - 2017-02-01
dependencies
- Bumps templates to v1.2.0 to take advantage of new methods available on
list
s

- Bumps templates to v0.25.0 to take advantage of async collection loaders. No changes to existing API.
0.25.0 - 2016-07-05
changed
- Minor code organization and private properties were changed. This is technically a housekeeping change since these methods weren't exposed on the API, but it's possible someone was using them in an unintended way.
0.24.0
dependencies
removed
- The bump in
templates
removes therenameKey
option from the.data
method. Use thenamespace
option instead.
0.23.0
fixed
- Bumps templates to v0.23.0 to fix bug with double rendering in engine-cache.
0.22.0
dependencies
- Bumps templates to v0.22.0 to take advantage of fixes and improvements to lookup methods:
.find
andgetView
. No API changes were made. Please let us know if regressions occur. - Bumps base to take advantages of code optimizations.
fixed
- fixes
List
bug that was caused collection helpers to explode
changed
- Improvements to lookup functions:
app.getView()
andapp.find()
0.21.0
dependencies
- Bumps templates to v0.21.0.
removed
- Support for the
queue
property was removed on collections. See templates for additional details.
0.20.0
dependencies
- Bumps templates to v0.20.0.
changed
- Some changes were made to context handling that effected one unit test out of ~1,000. although it's unlikely you'll be effected by the change, it warrants a minor bump
0.19.0
dependencies
- Bumps templates to v0.19.0
housekeeping
- Externalizes tests (temporarily) to base-test-runner, until we get all of the tests streamlined to the same format.
0.18.0
dependencies
- Bumps assemble-loader to v0.5.0, which includes which fixes a bug where
renameKey
was not always being used when defined on collection loader options. - Bumps templates to v0.18.0, which includes fixes for resolving layouts
0.17.0
dependencies
- Bumps templates to v0.17.0
0.16.0
dependencies
- Bumps assemble-render-file to v0.5.0 and templates to v0.16.0
0.15.0
dependencies
- Bumps assemble-streams to v0.5.0
0.14.0
dependencies
- Bumps templates to v0.15.1
deprecated
.handleView
method is now deprecated, use.handleOnce
instead
changed
- Private method
.mergePartialsSync
rename was reverted to.mergePartials
to be consistent with other updates in.render
and.compile
.
added
- adds logging methods from base-logger (
.log
,.verbose
, etc) - No other breaking changes, but some new features were added to templates for handling context in views and helpers.
0.13.0
- Breaking change: bumps templates to v0.13.0 to fix obscure rendering bug when multiple duplicate partials were rendered in the same view. But the fix required changing the
.mergePartials
method to be async. If you're currently using.mergePartials
, you can continue to do so synchronously using the.mergePartialsSync
method.
0.9.0
- Updates composer to v0.11.0, which removes the
.watch
method in favor of using the base-watch plugin.
0.8.0
- Bumps several deps. templates was bumped to 0.9.0 to take advantage of event handling improvements.
0.7.0
- Bumps templates to 0.8.0 to take advantage of
isType
method for checking a collection type, and a number of improvements to how collections and views are instantiated and named.
0.6.0
- Bumps assemble-fs plugin to 0.5.0, which introduces
onStream
andpreWrite
middleware handlers. - Bumps templates to 0.7.0, which fixes how non-cached collections are initialized. This was done as a minor instead of a patch since - although it's a fix - it could theoretically break someone's setup.
0.5.0
- Bumps templates to latest, 0.6.0, since it uses the latest base-methods, which introduces prototype mixins. No API changes.
[0.4.0]
- Removed emitter-only since it was only includes to be used in the default listeners that were removed in an earlier release. In rare cases this might be a breaking change, but not likely.
- Adds lazy-cache
- Updates assemble-streams plugin to latest
