Simple share

A simple and customisable knowledge sharing system. When publishing a link the open graph metadata are automatically scraped from source. When publishing a post the use can use markdown.

DEMO

This uses Supabase - the open source Firebase alternative

and Next.js - the React framework for production.

Getting Started

Make a .env file like this:

NEXT_PUBLIC_SUPABASE_URL=
NEXT_PUBLIC_SUPABASE_ANON_KEY=
NEXT_PUBLIC_WEBSITE_NAME=Your site name
NEXT_PUBLIC_TAGS_PIPE_SEPARATED=tag1|tag2|tag3

You can get SUPABASE_URL and SUPABASE_ANON_KEY from Supabase project API keys page at this url: https://app.supabase.io/project/<your-project-id>/settings/api

then, run the development server:

npm run dev
# or
yarn dev

Open http://localhost:3000 with your browser to see the result.
