Framer Symbols

Create symbols* in Framer

Description

Easily create reusable components in Framer, without the hassle of actually writing a class.

Check out some demos:

Form Element Symbols | iOS Control Center | Intro Animation | Common Event Buttons

Installation

Automatic Installation with Framer Modules

Manual Installation

Step 1 Download and copy Symbol.coffee in your project's /modules-folder.

Step 2 Require the Symbol-module in your project

{Symbol} = require 'Symbol'

Usage

Create a new Symbol

SymbolName = Symbol(template, states, events)

The Symbol-class has the following parameters:

Example

Let's create a Button-Symbol in its simplest form as an example:

#Require the module
{Symbol} = require 'Symbol'

# Initialize your symbol
Button = Symbol(button_default)

# Create buttonInstance
buttonInstance = new Button
  x: Align.center
  y: Align.center
  ...

... now you have your Button-symbol ready to use and you can go back in Design-Mode, edit away and the changes will reflect in all of your instances in Code!

Symbol States

The module also gives you the ability to create different states for your symbol in Design-Mode and apply those in Code.

You can either apply common or specific states.

Common States

Common states apply to ALL symbol-instances. They are being applied on initialization of the Symbol.

For each state you can define following properties:

Example

#Require the module
{Symbol} = require 'Symbol'

# Create common states
commonStates =
  disabled:
    template: button_disabled
    animationOptions:
      curve: Spring(damping: 1)
      time: 0.7
  active:
    template: button_active
    animationOptions:
      curve: Bezier.easeInOut
      time: 1

# Initialize your symbol
Button = Symbol(button_default, commonStates)

# Create buttonInstanceOne
buttonInstanceOne = new Button
  x: Align.center
  y: 100
  ...

# Create buttonInstanceTwo
buttonInstanceTwo = new Button
  x: Align.center
  y: 200
  ...

... now both buttonInstanceOne and buttonInstanceTwo have the 3 states default, disabled and active.

The animationOptions don't need to be supplied for each commonState, but can also be set as default for all states like this:

...
# Create common states
commonStates =
  animationOptions:
    curve: Spring(damping: 1)
    time: 0.7
  disabled:
    template: button_disabled
  active:
    template: button_active
...

Specific States

Specific states apply to a specific instance :scream_cat:

Specific states are being applied with layer.addSymbolState(name, template, animationOptions = false)

Example

#Require the module
{Symbol} = require 'Symbol'

# Initialize your symbol
Button = Symbol(button_default, commonStates)

# Create buttonInstanceOne
buttonInstanceOne = new Button
  x: Align.center
  y: 100
  ...

# Create buttonInstanceTwo
buttonInstanceTwo = new Button
  x: Align.center
  y: 200
  ...

buttonInstanceTwo.addSymbolState('specific', button_specific)

... now buttonInstanceOne has the state default and buttonInstanceTwo has the 2 states default and specific.

Buttons Prototype

Symbol Events

You can apply common events to ALL symbol-instances. They are being applied on initialization of the Symbol.

Define the commonStates-object like so:

commonEventsObject =
  eventName: -> yourEvent

You can also supply events to descendant-layers of your symbol, like so:

commonEventsObject =
  eventName: -> yourEvent
  descendantName:
    eventName: -> yourEvent

Example

...

# Create common events
commonEvents =
  MouseOver: -> @.animate "hover"
  MouseOut: -> @.animate "default"
  TapStart: -> @.animate "active"
  TapEnd: -> @.animate "hover"
  descendantName:
    Tap: -> print "Foo"

# Initialize your symbol
Button = Symbol(button_default, commonStates, commonEvents)

...

Working with text

As usual in Framer, text that is different between instances or changes its content between states, should be declared as template.

Text that stays the same for all instances and states, should be a normal text.

Framer Docs for textLayer

Under the hood

For your better understanding and if something shouldn't work as expected, I want to give you a little insight into what the module does.

tl;dr

The module basically animates between the default states of different layers.

...a little more detailed

The module creates a new layerType that extends Layer. This layer basically makes a copy of all the layers of the supplied symbol-template.

When you supply templates-layer for a new symbolState, the module applies the the target-layers default-state properties as properties for the new state you are creating. This happens recursive for all descendants of your symbol, so that every child-layer of a symbol has the same states as the parent.

On StateSwitchStart-event of the symbol, the module applies the stateSwitch to all descendants recursively, so that all states stay in sync.

Disclaimer

This module is meant to be filling the gap until Framer releases their own implementation of Symbols/Components. Even though I try to thoroughly test everything before I release new features, there's always a risk of me breaking stuff or API changes.

If you have any problems you run into or feature requests, feel free to open an issue or (even better) create a pull-request! <3

The code is based on the earlier exploration of Andreas Wahlström's createClass-module - so thanks for that! :tada:

Google Analytics

Out of curiosity I've integrated Google Analytics into the project to get an idea of how many people are using the module.

If you don't feel comfortable showing up in the stats, simply remove useGA(true) inside Symbol.coffee file.
