But you don't need to, because Bricks is a blazing fast masonry layout generator for fixed width elements.

5. Review Example Code

Bricks was developed with a modern JavaScript workflow in mind. To use it, it's recommended you have a build system in place that can transpile ES6, and bundle modules. For a minimal boilerplate that does so, check out outset.

Using NPM, install Bricks.js, and add it to your package.json dependencies.

$ npm install bricks.js --save

Refer to the releases page for version specific information.

Simply import Bricks, then instantiate it.

It's recommended that you assign your Bricks instance to a variable. Using your instance, you can:

• enable and disable the resize handler
• add and remove event handlers
• accommodate dynamically added elements

// import Bricks
import Bricks from 'bricks.js'

// create an instance
const instance = Bricks({
  // ...
})

Parameters passed to the constructor are detailed below.

Note that all parameters are required:

• A container selector
• A packed attribute
• A sizes array

A CSS selector that matches the grid wrapper.

const instance = Bricks({
  container: '.selector'
})

Note that the direct children of this element must be the grid items.

An attribute added to items already positioned within the grid.

const instance = Bricks({
  packed: 'data-packed'
})

Note that if the attribute is not prefixed with data-, it will be added.

An array of objects describing the grid's properties at different breakpoints.

When defining your sizes, note the following:

• Sizes must be listed smallest to largest
• Sizes must use min-width media queries (any unit)
• Width of the grid items at each breakpoint should be set in your CSS (in px)
• The size without the mq property is assumed to be your smallest breakpoint, and must appear first

// mq      - the minimum viewport width (any unit)
// columns - the number of vertical columns
// gutter  - the space (in px) between the columns and grid items

const sizes = [
  { columns: 2, gutter: 10 },
  { mq: '768px', columns: 3, gutter: 25 },
  { mq: '1024px', columns: 4, gutter: 50 }
]

const instance = Bricks({
  sizes: sizes
})

Bricks instances are extended with Knot.js, a browser-based event emitter. Use the event emitter syntax to add and remove handlers for the events emitted by the API methods. Review the emitter syntax here.

Bricks exposes the following methods, and corresponding events:

• pack
• update
• resize

Note that all methods, including those from the event emitter, are chainable.

Used to pack all elements within the container.

// pack ALL grid items
instance.pack()

// 'pack' is emitted when ALL items have been packed
instance.on('pack', () => {
  // ...
})

Note that it should be called when creating your instance, to pack the initial items.

Used to pack elements without the packed attribute within the container.

// pack NEW grid items
instance.update()

// 'update' is emitted when NEW items have been packed
instance.on('update', () => {
  // ...
})

Note that this is the preferred method for handling dynamically added items, because it will only operate on items that have not yet been packed (i.e. don't have the packed attribute).

Used to add or remove the resize event handler. It's recommended that you add the resize handler when you create your instance.

// add or remove the resize handler
instance
  .resize(true)       // 'true' adds it
  .resize(false)      // 'false' removes it

// 'resize' is emitted when resizing has resulted in a new matching 'size' object
instance.on('resize', size => {
  // 'size' is the newly matching size object
  // ...
})

Note that the resize handler fires the pack method if the resulting screen size matches a size parameter other than the current one. In this case, the pack event will be fired immediately before the resize event. Use the resize event only for breakpoint specific code, not code meant for when the grid has been packed.

Bricks depends on the following browser APIs:

• ES5 array methods: forEach, map, indexOf
• requestAnimationFrame
• matchMedia

Consequently, it supports the following natively:

• Chrome 24+
• Firefox 23+
• Safari 6.1+
• Opera 15+
• IE 10+
• iOS Safari 7.1+
• Android Browser 4.4+

To support older browsers, consider including polyfills/shims for the APIs listed above. There are no plans to include any in the library, in the interest of file size.
