Info: This is an Elm 0.19 update of an older Elm 0.18 package. What follows is the old readme. It's content's haven't been updated yet. Take the 'Missing pieces' section with a grain of salt: It's been a while since it has been updated.

Figma API with Elm

This package aims to provide a typed, Elm-friendly access to the Figma web API.

The API currently supports view-level operations on Figma files. Given a file, you can inspect its Elm representation, read or post comments, or export a rendered image of any node subtree.

Live "Swatches" example

The example below fetches a given Figma file and collects all the found colors and gradients used as background or paint fills.

Get a document file

First, let's create a authentication token and pass that to the getFile function, together with the file key we want to retrieve.

import Http
import Figma as F 


F.getFile
    ( F.personalToken "your-token" )
    "your-file-key"
    |> Http.send FileReceived

Then in the update function we can extract the FileReceived message payloadand store it in the model app:

FileReceived result ->         


    case result of 
        Ok response -> 
            ( { model | documentRoot = response.document }, Cmd.none )


        Err error -> 
            let 
                _ = Debug.log "Error while fetching file" error
            in                
            ( model, Cmd.none ) 

Note: The key can be extracted from any Figma file URL: https://www.figma.com/file/:key/:title, or via the getFiles function.

Export a document node to PNG

Here we start a request to export the node with ID 1:6 into a PNG file.

import Http
import Figma as F 


F.exportNodesAsPng 
    ( F.personalToken "your-token" ) 
    "your-file-key" 
    [ "1:6" ]
    |> Http.send ExportFinished 

Once finished the ExportFinished message will contain a list of ExportedImage, with the URL's for the rendered images.

Changes from previous version

• All top module functions now return a Http.Request value instead of Cmd, so you can chain calls together. See getFile documentation for an example.
• Added BooleanGroup and BooleanOperation.
• Added support for file versions.

Missing pieces

• Export geometry data
• Prototype transitions and easing settings
• Styles (see https://www.figma.com/developers/docs#style-type)
• Get specific nodes (see https://www.figma.com/developers/docs#nodes-endpoint)
• Starting frame for prototypes (see https://www.figma.com/developers/docs#canvas-props)
