@primer/figma-theme

Generate a JSON representation of style colors from a Figma file. Forked from jxnblk/figma-theme, which was created by Brent Jackson.

Installation

@primer/figma-theme requires Node.js 11.0 or higher.

To use the command-line API, you may want to install the package globally:

# with npm
npm i -g @primer/figma-theme

# with yarn
yarn global add @primer/figma-theme

If you plan on using the package as part of another Node.js project, you can install it to your dependencies:

# with npm
npm i @primer/figma-theme

# with yarn
yarn add @primer/figma-theme

If you've installed the package as a local dependency, you can run the binary with:

./node_modules/.bin/figma-theme

Basic usage

The CLI can parse JSON created from the Figma API and outputs JSON data to standard output.

Local files

To parse a JSON file created from the Figma API, pass the filename of the JSON file to the command:

figma-theme my-figma-export.json

You can also use - to specify stdin as the source for the JSON data:

./my-export-script.sh | figma-theme -

Download from the Figma API

If you specify your Figma personal access token via an environment variable or a .env file, the CLI can contact the Figma API and export the file for you:

# using an environment variable
FIGMA_TOKEN=asdf1234 figma-theme ...

# using a .env file
echo "FIGMA_TOKEN=asdf1234" > .env
figma-theme ...

To specify which file to export, use the --fetch option to specify a Figma file ID:

FIGMA_TOKEN=asdf1234 figma-theme --fetch xRlnI4wD4TEQGzOERdUfJz

To identify the Figma file ID, look at the part of the URL after /file/. For example, in the URL:

https://www.figma.com/file/abcdef123456/My-Figma-File

the ID is abcdef123456.

Figma styles

The styles in your Figma file must adhere to the following rules:

  • Create a nested structure by using / in your style names, e.g. functional / text / primary (spaces are optional)
  • Your style names must not contain a period
  • Every style you want to be a part of your theme must be used in the file; if a style is unused, its color will be null

Options

Options are passed as CLI flags.

  • --out <file>: redirect output to the given file
  • --pretty: format the JSON output to be more human readable
  • --metadata: include additional metadata for each style
  • --fetch <file_id>: fetch the specified Figma document from the Figma API

For a full list of options, run figma-theme --help.

Example

$ figma-theme --pretty test/fixtures/figma-file.json

{
  "functional": {
    "fill": {
      "red": "#ff0000",
      "blue": "#0085ff",
      "blue-alpha": "rgba(0,133,255,0.7)",
      "gray": null,
    }
  },
  "borders": {
    "green": "#007521",
    "orange": "#ff7a00",
    "black-fade-30": "rgba(0,0,0,0.3)",
  }
}
