Presets: Create your own

A preset is a setup function and a folder including _assets, _data and _includes (all optional).

To play around with a preset you can create a folder fire-theme.

You then create the setup function for it with only one property called path which will allow Rocket to properly resolve it.

Create a Preset Config File

👉 fire-theme/fireTheme.js

import path from 'path';
import { fileURLToPath } from 'url';

const __dirname = path.dirname(fileURLToPath(import.meta.url));

export function fireTheme() {
  return {
    path: path.resolve(__dirname),

Once you have that you can start filling in content you need.

For example a we could override the full layout.css by adding a it like so

👉 fire-theme/layout.css

body {
  background: hotpink;

Once you have that you can add it to your Rocket config.

NOTE: The order of presets is important, as for example in this case we take everything from rocketLaunch but later override via fireTheme.

👉 rocket-config.js

import { rocketLaunch } from '@rocket/launch';
import { fireTheme } from 'path/to/fire-theme/fireTheme.js';

export default {
  presets: [rocketLaunch(), fireTheme()],

Publish a Preset

If you would like to publish a preset to use it on multiple websites or share it with your friends you can do like so.

  1. Pick a name for the package => for this example we take fire-theme.

  2. Create a new folder fire-theme

  3. Create a folder fire-theme/preset copy fireTheme.js from above into preset/fireTheme.js

  4. Add a 👉 package.json

      "name": "fire-theme",
      "version": "0.3.0",
      "description": "Fire Theme for Rocket",
      "license": "MIT",
      "type": "module",
      "exports": {
        ".": "./index.js",
        "./preset/": "./preset/"
      "files": ["*.js", "preset"],
      "keywords": ["rocket", "preset"]
  5. Add a 👉 index.js

    export { fireTheme } from './preset/fireTheme.js';
  6. Add a 👉

    # FireTheme
    This is a theme/preset for [Rocket](
    ## Installation
    npm i -D fire-theme
    Add it to your 👉 `rocket.config.js`
    import { fireTheme } from 'fire-theme';
    export default {
      presets: [fireTheme()],
