Nebula Genesis

nebula-genesis is part of the Nebula suite.

Nebula connects Notion API and GatsbyJS to automatically create static websites.

Nebula Genesis acts prior to the website generation, by querying and caching Notion data and files.

How to use

1. Install

Install nebula-genesis as a dev dependency in your website project.

npm i -D nebula-genesis

2. Run

Query databases and pages according to your needs.

It is a normal use case to run 2 or more times nebula-genesis, with different CACHE_FOLDER_NAME, to fetch content from mutiple databases or varying filters.

This will download content in a cache folder, as detailed in Download folder section.

Required and optional arguments are detailed in the Arguments section.

node node_modules/nebula-genesis/index.js [...args]

Inside CACHE_FOLDER_NAME folder, content is stored on the following structure :

• cache.json, which contains nebula-genesis metadata, currently only the LAST_RUN date,
