Installation

Requirements​

  • Node.js version >= 20.x.x or above (which can be checked by running node -v). You can use nvm for managing multiple Node versions on a single machine installed

Scaffold project catalog​

The easiest way to install EventCatalog is to use the command line tool that helps you scaffold a skeleton EventCatalog. You can run this command anywhere in a new empty repository or within an existing repository, it will create a new directory containing the scaffolded files.

npx @eventcatalog/create-eventcatalog@latest my-catalog

Project structure​

Assuming you named your site my-catalog, you will see the following files generated under a new directory my-catalog/:

Running the development server​

To preview your changes as you edit the files, you can run a local development server that will serve your website and reflect the latest changes.

cd my-catalog
npm run dev

You will be able to see your EventCatalog at http://localhost:3000/docs

Congratulations! You have just created your first EventCatalog site!

Build​

EventCatalog uses Astro under the hood. To build the catalog run the following command:

npm run build

All contents will be generated within the /dist directory.

EventCatalog is currently a static website so you can host this folder anywhere you like.
