assemble-core

assemble-core

The core assemble application with no presets or defaults. All configuration is left to the implementor.

This library, assemble-core, was designed to give implementors and hackers the baseline features and API for creating rich and powerful node.js applications. Learn more about what you can do with assemble-core.

Install

Install with npm

$ npm i assemble-core --save

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();
app.create('pages');

app.page('foo', {content: 'Hi, my name is <%= name %>'})
  .use(function (view) {
    if (!view.contents) {
      view.contents = fs.readFileSync(view.path);
    }
  })
  .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();

Templates API

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.

---

File System API

Assemble has the following methods for working with the file system:

• src
• dest
• copy
• symlink

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 to src 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 to dest 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
• build
• watch

.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 name
• fn {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 exposes err

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']);
});
