Get your Figma file into R

Pedro Duarte Faria

1. Introduction

You might have some Figma files that you want to bring into R, to analyze, or, use the visual attributes of the objects from this file to compose a layout that you want to use in a RMarkdown/Quarto file.

The figma package allows you to that. It uses the Figma API to bring all of your Figma file data into R. It does this, by sending a HTTP request to the Figma API to collect all of your Figma data, and then, it parses this data into a R native object, so you can easily use it in your R process.

library(figma)

But in order to use the Figma API, you need to collect two key variables about your file and your credentials. They are:

However, if you want to use get_figma_page(), you will need to collect a third information, which is the node_id, or the ID that identifies a canvas/page of your Figma file. We will talk about this ID on section 1.2.

1.1 Is always nice to read the official Figma API documentation

Some of the information described in this vignette comes from the official Figma API documentation, and in order to learn more about a specific subject, is always a good idea to read about that subject directly from the source 😉.

I will give you direct links to specific parts of the documentation throughout this vignette, but if you want to read the complete documentation, you can access this link.

1.2 Finding the key (or ID) of your Figma file

The file key (or the file key), is a random text that identifies your Figma file. The Figma API uses this key to identify which specific Figma file you are requesting for.

You can find the key (or ID) of your Figma file by looking at the URL in your web browser, when you access your Figma file at the Figma platform. As an example, lets use this Figma file entitled Untitled (I will not make a joke on that 😅):

An example of Figma file

An example of Figma file

If we look at the top of my web browser, we have the following URL:

https://www.figma.com/file/hch8YlkIrYbU3raDzjPvCz/Untitled?node-id=0%3A1

The key (or the ID) of this file is "hch8YlkIrYbU3raDzjPvCz". This means that the URL of every Figma file is composed of this structure. So in order to use the functions from the figma package, you should always collect this :file_key portion of the URL, to get the key to your file.

https://www.figma.com/file/:file_key/:file_title?:node_id

This also means that, if you want to use get_figma_page(), you will need to collect the :node_id portion of the URL as well. This portion gives you the node ID, or, in other words, the ID that identifies the canvas/page you are on. This portion of the URL is usually a key-value pair, where the ID of your node is after the equal sign (=).

For example, by looking at the URL example that we gave above, we know that the canvas/page where I am is the page of node_id = "0%3A1".

1.3 Get your personal access token

You can read more about the authentication process and the use of personal access tokens, in the section “Authentication” of the Figma API documentation. If you do not have a personal access token, you can create one in the Figma platform. Just log in the platform, and click on the Settings section, like in the image below:

Settings of Figma platform

Settings of Figma platform

After that, look for the Personal access token section of the settings, like in the image below. This is where you can create all of your personal access tokens. Just add a description (or a “alias”) to your token, and press Enter. A pop-up should appear in your screen with your new token.

Personal access token section in settings

Personal access token section in settings

The Figma API uses this secret token to identify you, to know that is you that is requesting for a file, and not someone else. Because of this, is important to keep this token a secret, because if someone have it, they can access your Figma files through the API.

A standard way to store these passwords, is to store them in the .Renviron file, but there are many other methods that are good alternatives too. A good place to start is the vignette from Hadley Wickham.

1.4 Use get_figma_file() to get your Figma file

Now that you have the key (or ID) that identifies your Figma file, and your personal token that identifies yourself, you can use get_figma_file() to get your Figma file:

file_key <- "hch8YlkIrYbU3raDzjPvCz"
# Insert your personal token:
token <- "Your personal token ..."

result <- figma::get_figma_file(
  file_key, token
)
# A `response` object:
print(result)
Response [https://api.figma.com/v1/files/hch8YlkIrYbU3raDzjPvCz]
  Date: 2022-10-29 16:56
  Status: 200
  Content-Type: application/json; charset=utf-8
  Size: 4.58 kB
{"document":{"id":"0:0","name":"Document","type":"DOCUMENT","children":[{"id":"0:1","name":"Page 1","typ...

1.5 Using the response object

The functions from figma package have the philosophy of giving (by default) the most raw and unprocessed result as possible to the user. This is good for debugging situations, because it gives all the available information to the user.

However, this unprocessed result is usually not strucutured in a very friendly and useful format, which makes analysis and transformation pipelines harder and more complex. That is why get_figma_file() comes with more output formats available through the .output_format argument, which we will describe later.

To give you an useful example, you can access the exact response object shown in the example of section 1.4. This response object is stored in a data object called untitled_file, that you can access with data("untitled_file", package = "figma"). This object untitled_file contains all of the data from the Figma file shown in section 1.2.

As you can see in the result below, a response object is just a simple R list with many elements:

str(untitled_file)
#> List of 10
#>  $ url        : chr "https://api.figma.com/v1/files/hch8YlkIrYbU3raDzjPvCz"

#>  - attr(*, "class")= chr "response"

All of your Figma file data is in the content element, so, you would use the command untitled_file$content to access it. But, by default, the Figma API sends the data of your Figma file as raw bytes:

head(untitled_file$content)
#> [1] 7b 22 64 6f 63 75

So you need to convert these bytes in a more useful format like a JSON object, or a character vector, or as pure text. To do this conversion, I recommend you to use the httr::content() function. By default, this function converts the raw bytes into a R list.

list_of_nodes <- httr::content(untitled_file)
names(list_of_nodes)
#>  [1] "document"      "components"    "componentSets" "schemaVersion"
#>  [5] "styles"        "name"          "lastModified"  "thumbnailUrl" 
#>  [9] "version"       "role"          "editorType"    "linkAccess"

The canvas/pages nodes are in the list_of_nodes$document$children element, and the objects nodes are in the children element of each canvas/page node (e.g.  list_of_nodes$document$children[[1]][["children"]]).

first_canvas_node <- list_of_nodes$document$children[[1]]
first_object_node <- first_canvas_node[["children"]][[1]]

1.6 Output a Figma Document object

With .output_argument = "figma_document", get_figma_file() will output a Figma Document object, instead of a response object.

file_key <- "hch8YlkIrYbU3raDzjPvCz"
# Insert your personal token:
token <- "Your personal token ..."

figma_document <- figma::get_figma_file(
  file_key, token,
  .output_format = "figma_document"
)
# A `figma_document` object:
print(figma_document)

Or, analogously:

figma_document <- figma::as_figma_document(untitled_file)
figma_document
#> <Figma Document>
#> 
#>  * Number of canvas: 2 
#>  * Number of objects in each canvas: 3 2

This object is just a R list with class figma_document. The main differences between this object and the response object are:

In a figma_document object, all of the document metadata of your Figma file (like the name/title of the file, the last time it was modified, its components, etc…) is available in the document element:

str(figma_document$document)
#> List of 13
#>  $ id           : chr "0:0"
#>  $ type         : chr "DOCUMENT"
#>  $ name         : chr "Untitled"
#>  $ components   : Named list()
#>  $ componentSets: Named list()
#>  $ styles       : Named list()
#>  $ schemaVersion: int 0
#>  $ lastModified : chr "2022-10-25T00:36:59Z"
#>  $ thumbnailUrl : chr "https://s3-alpha-sig.figma.com/thumbnails/065f8c7c-af9c-4f7f-bb80-e1c9ad6b62b5?Expires=1667779200&Signature=Gz5"| __truncated__
#>  $ version      : chr "2514657369"
#>  $ role         : chr "owner"
#>  $ editorType   : chr "figma"
#>  $ linkAccess   : chr "view"

Furthermore, you can get the data of each canvas/page (and their respective objects) in the canvas element:

names(figma_document$canvas[[1]])
#> [1] "id"                   "name"                 "type"                
#> [4] "objects"              "backgroundColor"      "prototypeStartNodeID"
#> [7] "flowStartingPoints"   "prototypeDevice"

And the data of all the objects present in each canvas is found in the objects element:

first_canvas_node <- figma_document$canvas[[1]]
first_object_node <- first_canvas_node$objects[[1]]
str(first_object_node)
#> List of 12
#>  $ id                  : chr "1:2"
#>  $ name                : chr "Background"
#>  $ type                : chr "RECTANGLE"
#>  $ blendMode           : chr "PASS_THROUGH"
#>  $ absoluteBoundingBox :List of 4
#>   ..$ x     : num -379
#>   ..$ y     : num -277
#>   ..$ width : num 793
#>   ..$ height: num 549
#>  $ absoluteRenderBounds:List of 4
#>   ..$ x     : num -379

#>   ..$ :List of 3
#>   .. ..$ blendMode: chr "NORMAL"
#>   .. ..$ type     : chr "SOLID"
#>   .. ..$ color    :List of 4
#>   .. .. ..$ r: num 0.851
#>   .. .. ..$ g: num 0.851
#>   .. .. ..$ b: num 0.851
#>   .. .. ..$ a: num 1
#>  $ strokes             : list()
#>  $ strokeWeight        : num 1
#>  $ strokeAlign         : chr "INSIDE"
#>  $ effects             : list()

1.7 Output a tibble::tibble() object

With .output_format = "tibble, get_figma_file() will output a tibble::tibble() object, instead of a response object. This is probably the most useful and friendly output format that you can use:

file_key <- "hch8YlkIrYbU3raDzjPvCz"
# Insert your personal token:
token <- "Your personal token ..."

tibble <- figma::get_figma_file(
  file_key, token,
  .output_format = "tibble"
)
# A `tibble` object:
print(tibble)

Or, analogously:

tibble <- figma::as_tibble(untitled_file)
tibble
#> # A tibble: 5 × 7
#>   canvas_id canvas_name canvas_type object_id object_name   objec…¹ object_attrs
#>   <chr>     <chr>       <chr>       <chr>     <chr>         <chr>   <list>      
#> 1 0:1       Page 1      CANVAS      1:2       Background    RECTAN… <named list>
#> 2 0:1       Page 1      CANVAS      5:2       Paragraph     TEXT    <named list>
#> 3 0:1       Page 1      CANVAS      5:3       Arrow         VECTOR  <named list>
#> 4 5:4       Page 2      CANVAS      5:5       BackgroundPa… RECTAN… <named list>
#> 5 5:4       Page 2      CANVAS      5:6       Texto da pág… TEXT    <named list>
#> # … with abbreviated variable name ¹​object_type

Each row in the resulting tibble, is a object present in one of the canvas of your Figma file. As an example, the Figma file stored in untitled_file have 2 canvas/pages: 3 objects in the first canvas, and 2 objects in the second canvas. So 3 objects + 2 objects = 5 rows in the output tibble.

The columns with canvas_ prefix stores the metadata about the canvas on which the object of the corresponding row is. And the columns with object_ prefix stores the data about the object of the corresponding row.

Each object can have a different type (it can be a RECTANGLE, a TEXT, a VECTOR, etc.), and different types of objects usually have different kinds of attributes. The attributes of each object are stored in the object_attributes column.
