Writer

The writer takes your token collection and writes them to the disk. Theemo can write to multiple targets, like so:

import { styleDictionaryWriter } from '@theemo/style-dictionary';
import { defineConfig } from '@theemo/cli';

export default defineConfig({
  sync: {
    writer: {
      targets: styleDictionaryWriter({ ... })
    }
  }
});

All these targets are writer plugins. Theemo provides some, but you can write your own, too.

Available Writer Plugins

• Style Dictionary Writer

Write your own Writer Plugin

The plugin should implement the WriterTool interface, with only one write() function to keep the API fairly minimal.

Here is the minimal starter code:

index.ts

import YourWriter from './reader';

import type { YourWriterConfig } from './config';
import type { TokenCollection } from '@theemo/tokens';
import type { WriterTool } from '@theemo/sync';

export function yourWriter(config: YourWriterConfig): WriterTool {
  return {
    write(tokens: TokenCollection) {
      const writer = new YourWriter(config);
      const tokens = writer.write(tokens);
    }
  };
}

writer.ts

import type { YourWriterConfig } from './config';
import type { TokenCollection } from '@theemo/tokens';

export default class YourWriter {
  #config: YourWriterConfig;

  constructor(#config: YourWriterConfig) {
  }

  write(tokens: TokenCollection): void {
    // do your work here
  }
}

config.ts

export interface YourWriterConfig {
  // place your config options here
}

Use your reader aside to the figma reader:

import { styleDictionaryWriter } from '@theemo/style-dictionary';
import { yourWriter } from '<see-above>';
import { defineConfig } from '@theemo/cli';

export default defineConfig({
  sync: {
    writer: {
      targets: [
        styleDictionaryWriter({ ... }),
        yourWriter({ ... })
      ]
    }
  }
});
